Dad's first flight RV-7 @ Tyler TX...Kyle Gee post

After trading a partially built kit for his Globe Swift, my Dad, Robert Gee, got his airworthiness certificate last Monday from Mel after working on it off and on for at least 5 years. I moved to California a couple of years ago for work, so I hopped in my RV-7 and flew from Bay Area to Tyler TX in 2-4 hour legs. My brother came up from Houston and we flew chase as my Dad piloted the RV for the first time. Flew perfect. Had to work some baffling due to some warm cylinders and some panel bugs still to work out. He definitely had the RV grin....we all did.


Thank you to Aerotronics

Would like to acknowledge the great service I have received from Jason Smith at Aerotronics. They built my panel years ago and I recently had some issues with my ADS-B (pointed out to me by a friendly call from the FAA). When I called them they said to ship them my transponder, did a no charge software update and sent in back..... and the problem was worse than before. When I reached out for help getting things working I felt like I was their number one customer and that when I called they dropped whatever they were doing to chat with me. They were very helpful and helped me work through the issue and get it fixed. While I did spend a fair amount of money with them years ago, it certainly wasn't a "warranty issue" and I feel they really went above the call of duty. Thanks guys

Sky Designs RV-6/7 Wheel Pant Design ...budy O mine Ken.

A More Minimalist Approach
The timing of this thread coincides nicely with development of an integrated gear leg & lower intersection fairing for the RV-6 and RV-7.

The design approach I chose is a fun counterpoint to the approach WAT chose for their Cirrus fairings. You can see that the intersection fillet is much smaller resulting in less wetted area and less frontal area.

Another factor in sizing of the intersection fillet was my desire to not have so many "extra" screws just for attachment of the intersection fairing to the wheel fairing. Only one of the five screws attaching the intersection fairing is not already part of either holding the front and rear wheel fairing halves together or a bracket attach location.

Help with Pilots n Paws Mission ...Dan Langhout post

Just thought I would put this out here to see if there was any interest. I have thrown my hat in the ring to help transport a 48 lb, 2 year old, female hound mix that needs to get to the Richmond, VA area. I have signed up to pick her up near Alexandria, LA and transport her to the Huntsville, AL area (KMDQ, KFYM, etc). She still needs a ride or two from there to the Richmond area. No takers so far after a week on the PnP ride board. Here is a link to the PnP posting.  They have apparently been trying to move this dog for several months.


Fast?  ...JFCRV12

So, we're having incredible weather today in southwest Ohio (75 degrees, blue skies, calm winds). And figured I'd try seeing how my 12 does vs POH. Mind you, mine does not yet have Wheel Pants on. Turns out I'm beating (according to Dynon) the POH #s. But, admittedly, I'm not at gross. This was full fuel + me (190lbs) and some miscellaneous stuff (towbar, quart of oil, etc.). Net, lets say I was at 1075lbs or so. 755 (empty) +200 (me with stuff) +120 (fuel)

POH says @ 7500 ft I should see the following KTAS:


Q: Prefabricated Fuel Tank ...RV-12

Whilst I await my Emp & Wing kits to ship I am getting ready to order the Fuse kit, but can't decide whether to also order the pre-made fuel tank or just build it myself.

For those that have gone before - if you done it over would you build it again yourself, or go with the $600 pre-built option? And how much time would this save?

Reading a few threads I know it looks like one of the messier jobs on the build but my main concern is having to chase around finding & fixing leaks, but again i'm not sure how much of a problem this is in reality?

A: (Scott) The prefab RV-12 tanks are built (and then leak tested) with pride right here at the Van's Aircraft facility in Aurora Oregon. They guys that do the work have built hundreds of tanks.
They are used in all production SLSA RV-12's and are offered to RV-12 home builders as an option.

The alternative of course is to build it yourself. Many hundreds of builders have done so successfully by carefully following the KAI instructions.


Air Box to Cowling Connection ....various methods

Q: I'm looking for ideas on how to connect the front of the air box on a vertical induction IO- 360 to the air scoop on the cowling. This is the air scoop below the propeller, directly in front of the Vans air box - not the snorkel setup.



T-Bolt Hanging ...Bart.

About a year after ordering, my Thunderbolt rolled into the hangar on Friday. Great excitement followed by a whole Saturday of my wife and I muscling that beast into the 4 engine mounts. Hi temps and hi humidity - lots of cursing - but got it hung! For some reason I just don't remember the IO-540 being so difficult but that was ten years ago

Thanks to Dave Farmer, a great guy! ...Ken C.

There are lots of great folks associated with RV airplanes, and Dave Farmer is among them. Short Explanation: My wife and and I have an unpainted RV-12 built by the wonderful young folks of Aviation Nation. Unfortunately, somewhere along the way some of the decals got lost. Some of those, Van's no longer keeps in stock with no plans to carry again. On VAF, I put out a feeler to find those decals. Enter Dave. He had some of the ones I was looking for. He sent them and refused any payment. Many Thanks Dave. I hope I can return the favor. One more little thing about Dave. He's retired MD State Highway Police. For me, that's a double "Thanks"!

  Got to fly Monday up to KGLE and back for gas - first RV time in two weeks.  Light winds from the north (for a change) had the morning temps in the 70's.  Drug it down a friend's runway north of Denton and rocked the wings.  Got a text later...he saw it.  Felt great to be off the surface RV'n and a grin'n.

My RV Weekend ...many

"As for me, I flew twice, Fallbrook (CA) to Santa Paula (CA) and back to Fallbrook. L18 - KSZP - L18

We grabbed lunch in Santa Paula today (airport restaurant is open, with patio seating available), and enjoyed watching the banner towing airplanes, and the tailwheel aircraft practicing their pattern work. As we departed, a red RV was entering the pattern for landing.

Really nice day to fly today, despite a bit of smoke in the air from the fire to the east. Perfectly smooth air, and while it was a bit hot on the ground, it was a comfortable 60* F at 10,500' / 11,500' flying to and from.

Hope that everyone was able to do something enjoyable with their RV this weekend!"

"I flew my 9 on my first Petsnpaws mission. Flew 1A3 to D73 where I picked up a lab mix puppy. Then fly him to KHKY And then back to 1A3 the next day.  10,000 MSL over the NC mountains on the return flight. Three RNAV GPS approaches. Great flying."

"Getting ready for condition inspection and finding issues with airplane..."

"With a pending hurricane looming in Florida, (a big nothing as usual), I took the opportunity of no-fly to replace my yellowing flap tape. I installed the new stuff under the wing this time. I can't say enough good things about this Goo Gone stuff. The adhesive was hard as a rock stuck to the paint. I sprayed this stuff on, waited 30 minutes, and it scraped off with my fingernails. Totally non toxic and easy on the hands. Plane is so much cleaner looking."

Debrief: 9A Trip to San Juan Islands ...tcard


9A Status Update ...PilotjohnS

Today was a warm day, perfect for canopy work.

This weekend was all about cutting the canopy down to size. The on-line experts suggested to use the Dremel Max Saw. This worked out very well. However, they recommended the SM500 plastic blade, I found this to be a really coarse cut. I chose to use the SM510 metal blade. This blade is just like the cut off wheel Van's supplies in the kit, but for the Max Saw. With this blade, if the cuts are made carefully, there is very little clean up sanding. I took everything down to 240 grit after the cut, before moving the canopy.

The cutting wasn't as bad as others have made it out to be.It is only a (very expensive) piece of plastic. It isn't like it is a Ferrari or anything. Like everything else on this build, I was stressing over it and it turned out to be not worthy. With all the others writing of their experience, that background helped a lot. (Thank you)

I taped the canopy to the frame for a fit check using wire as a Sika spacer. Seems I have a few more trim cuts to make, so I figure another whole day in the sun and then it will be ready to bond.

I am thinking of not using the trim piece that sits on the outside, down the middle spine. It seems with the Sika bonding method, there is no need for this strip. But
I think I will need to bond on a thrust washer for the handle thou.

Trip Report: DFW to Yellowstone ...Walt 7A

Just got back from a GREAT 6 day trip to Yellowstone and thought I'd share a few pictures. Approx 1000 miles/6 hrs flying each way and 600 miles of driving thru the Yellowstone and Grand Titan National Parks, also spent a day in Jackson Hole. What a great trip, wife is already planning the next adventure! (many pics)


Boat Trip Update: Disembark Day ...tcard 9A

The sun rose on our final morning. It was departure day. The shore trips were completed and up came the anchor. Once again, the magenta line kept us clear of shore, and with almost no wind we motored home.


Point the Nose Toward Home ...tcard 9A

Being exhausted is a tremendous sleep aid. My head hit the pillow a little after 10pm, and I'm not sure I moved until the alarm went off at 6. We are crossing desert and high terrain, a combination for rough air, so we try to get out of Dodge early. I was moving before Scott, so I ran for coffee and muffins to deliver to the other half and returned just as Scott was becoming consicous. And we weren't behind schedule...YET. So far as our hosts knew, it was still 5-something in the morning.


My Father's RV-4 from 1996 ...NotaPilot

My father had an RV-4 with a pretty nice paint job. He also wrote two books on the RV-4 in the 1990's. One was an operators manual, the other was a maintenance manual. They aren't doing us any good sitting in a box. I scanned them both in and so if someone wants a copy I can give you a PDF to use and share.


Tricky Electrical Issue - Need advice

Fellow RVers,
I have a RV-7A with Titan IOX-360, Plane Power alternator (with internal volt reg), VPX (Vert Power sport) and dual Dynon Skyview Classic. For some time now I've been experiencing fluctuating and high ammeter readings on the Skyview EMS (jump from normal to 90+ Amps) anytime I fly. At first I was quick to land but after replacing the alternator, checking all wiring for loose connections, and replacing the battery (PC 680) I am still having the same issue. This only occurs once the engine is warmed up (happened much less in winter when temps were cooler) so I suspect maybe the voltage reg or one of the shunts is overheating and causing the faulty readings. There has been zero signs of damage due to high amperage on any wires, battery, etc and I even had the old alternator bench tested and both it and the volt reg checked out fine (so now I have a spare...). I am considering making a hole in the front left intake air ramp and running a hose to put air directly onto the voltage regulator to cool it...I have seen others do this but I'm still shooting in the dark and was hoping this sage and experienced group might offer thoughts, experiences to help. TIA! and pictures attached.


JDAir Latch Install Pics ...Swiss14A

Made new angles and tested on scratch (which was good, especially because I made a lock as well). With new angles you can testfit the whole assembly including latch and angles and then matchdrill the upper angle from the skin. I figured this is easier than using the stock angles and match everything else...

RV-10 Grip Bushing Reconfigured 7*

Tosten mfg has reconfigured the RV 10 mounting bushing.  The new bushing works with both the stock and Aerosport panels. The 7 degree offset brings the grip aft to clear the panel and provide a more ergonomic feel. We also cut and mount the grips to your existing shafts similar to what we do for the RV-14.   Contact Kevin @ Tostenmfg.com for more info.

Boat Day (9A trip) ...tcard trip installment


Electrical system issue during Comm Transmission

Not that it matters for this question, but I have an RV-8A that I bought a little more than a year ago, constructed by a reputable builder and with avionics installed professionally.

About two weeks ago, keying the radio for transmission with the switch on the grip caused the AP to disengage and reboot. Further, I noticed that the manifold pressure increase 10# during transmission, dropping back down to the correct pressure when I released the mic key.

There is no static in the radio at any time, including during transmission.

I was on a trip and determined to get back to home base and did so, but an additional symptom occurred - now when I key the mic the ammeter goes to -20.

I do not know the make of the grip, but it has switches for the mic, AP disengage and trim (although no problems when I trim the aircraft). The logical place to start the search seems to me to be in the grip - looking for a frayed wire. My bet is that I have something going to ground when I trip the mic hence the ammeter reading.

Anyone have any similar experience or advice?


Angled bush for Tosten stick grips ...Andy Miller RV-10

Just another data point...

I made a replacement bush for the Tosten grips, where the bore (to accept the shaft of the Tosten grip) is angled about 8 degrees back. This increases the clearance between the instrument panel and the grip by about 3/4" - 7/8".

This is not critical for us as we have the standard Vans instrument panel, but it improves the ergonomics of the grip as it moves it to a more natural vertical orientation, rather than its standard angled forward fit.


Repitching Prop Continues: Video ...NinerBikes RV-12 video

This was taken after re pitching the prop on N72DJ for the 2nd time, from 71.4 to 72.0, for less cruise speed bite and more climb. Getting 5100 rpm on the runway and 5000 to 5020 rpm at 75 kts on takeoff. Still doesn't have a great climb rate.

Will re pitch again to get closer to 5150 to 5175 at 75 kts for a better fpm climb rate. Will probably try 72.8 degrees this time.

At 28 yrs old....she deserved a little nip tuck ...BH1166

Love my 1992 6A....It is not new, so I thought a little facelift ( paint and vinyl striping) might be fun. Repainted the entire tail ( vertical, horizontal stab , rudder and elevator) new N numbers on rudder, painted leg fairings, wheel pants, cowl and spinner. This week I put on the striping I purchased from Aerographics. I like the new clean look. Now what to do on the spinner ? Gotta have some red there for visual balance . <g>


Sucia Islands ...tcard

Monday morning arrived, and it was time to fuel up on a full breakfast. Thanks Sandy! Then, off to the marina for a shower. You buy tokens and get 7-minutes of water per token. Scott and I both hatched a plan for an abbreviated shower, but it turned out seven minutes was plenty of time if you treated it like a clearance from tower that include the words 'No Delay.'


Critique my G3X VFR Load Analysis ...Draker

Recently working on a load analysis for my build's future electrical system, for the purpose of correctly sizing my alternator. This is a pretty simple single alternator, single main battery, small backup battery system. But it has a pretty much fully loaded Garmin G3X setup. Was hoping I could get away with a 40A alternator, but unless I estimated something wrong here, that doesn't look achievable. I cannot squeeze myself under 40A (minus 10% safety margin) in either takeoff or approach configurations.

Can anyone see a flaw in my calculations or reasoning here? If not, it looks like I'd be better off with a 60A alternator than a 40A and will need to pay the weight penalty.


High Oil Temp ...jtate747

My oil temperature has been increasing over the last few months. In an effort to troubleshoot, I have operated in harsh conditions to check temp accuracy, oil cooler in/out temps when high, etc. Harsh meaning afternoon flights (103*F, full power)
Details: RV-6A, O-360, constant speed prop
I have checked the following:
- Baffles - all appear to seal very well
- Oil Temp accuracy- checked sump at 240*F, after shutting down at 241*F
- Vernatherm (boiled in H2O..... opened at 184-188*F
- upgraded from 7 row cooler to 9 row cooler
- changed ducting from 3" to 4"

It takes about 15-20 minutes to reach 245*F with OAT of 103*F.

My thoughts are
(A) vernatherm expands ok, but not seating right- restricting flow
(B) timing haven't checked that, but a friend mentioned that today
(C) outflow duct. Right now the oil cooler is open on bottom side. Another friend said to duct the flow out of engine compartment into stream for "suction"

Any help would be appreciated.

Getting ready to countersink the holes for the front seat shoulder harness screws. Took me forever to find a suitable bit. Got excited, then discovered you have to have a $45 minimum order. Another site sells it for $76. Anyone have a bit they can loan my husband and I? Another option is to see if 5 or more folks want to get together to do a bulk order and then just mail the bits to those who want in. The bits would cost each of us $9.58 including the company shipping cost. I don't even care how much it would cost to send out those 4 other bits...

Do you know this pin?  ....Bob Collins -12iS

Anybody know this pin?

It's the pin from one of the wires in a Rotax 912iS connector. The one in which is twist and remove the white pins in page 46is-10 Step 1. The one in which it's anticipated that the pins you're removing my break.

Yep, and when it did, the recoil of my needle nose pliers took out pin #10.

I recognize the connector -- the same ones Vertical Power used in the VP-50 and fortunately I still had those fabulous manuals Marc Ausman provided way back then. So I eventually figured out the proper way to remove the pin on the broken wire.

But now I need to find these pins.

Anyone recognize it, have a part number/description and know a supplier?

Closing Wheel Pant Gap to the Tire ...DanH input

950 hours now. There is no glass bottom in the rear portion of the wheel pants; it was cut away after the mold process. The urethane rubber/glass fabric can ride over moderate rough places without damaging the pants. Clearance at the lowest point is only 3/4" inch, so I do apply a patch every few years over a worn spot which tends to form just aft of the tire. I've never had a flat, but there should be enough clearance along the sidewall to not break the pant.


Quirky Thing Seen.  Whatsit?  ...Vlad


Engine Quit on T/O ...DanH input

IF my guess is correct, you're going to find trash in the divider and the nozzle restrictors, notably the cyls reported as cold, #'s 3/4. I'd go straight to those restrictors first. You can see through them if you hold them up to the light, or just use a 10x magnifier. The nozzle passage is larger than the restrictor bore, so no real need to remove the nozzles from the cylinder head unless you want to do a bottle check. Just unscrew the little nut on the end of the stainless line, bend the line very slightly to the side, and remove the restrictor from the top of the nozzle.

Emergency Landing This Morning ...airguy

This happened to me this morning about 7am just after sunup, I'm still processing the details in my head, but here's the short version.

I was headed out to go see some friends up north, wheels up at first crack of dawn 6am this morning, and cruising along fat dumb and happy at 9500 on VFR flight following when I noticed that my AFR (air-fuel-ratio) was quite a bit leaner than I normally run it. I tweaked my mixture a bit to get it back where it should be, but my mixture control was significantly richer than it should have been for that condition. That made me take a good long look at the engine, specifically the fuel pressure - which normally runs 40-42 psi (SDS injected engine), and it was down around 29. I watched it for a few more minutes, 28. 27, 25. Definitely slowly dropping and my low fuel pressure alarm goes off. The engine starts to stumble, the AFR indicates 18 (way too lean), so I go full rich, AFR only comes up to mid-16's and my fuel pressure continues to drop. Of course I changed tanks, changed fuel pumps, changed injector boards, all the things you are supposed to do - and it didn't do anything.  --->

I have a Ray Allen flap position sensor and I need to help on how connect the 3 wires on the sensor to the Dynon EMS. The picture below shows the wiring diagram of the Ray Allen position sensor and the the Dynon EMS wiring to a generic flap sensor.

My question is the EMS diagram only shows 2 connections, one from the sensor wire (Green) and Ground wire. On the Ray Allen it doesn't show the ground wire or power wire. From the picture below, can you tell me which wire goes to where, and does it mean one of the 3-wires on the Ray Allen sensor is not connected?

Announcement: RV-10 parts will be transitioning to final-sized matched holes ...mothership

Over the next several months, we will be transitioning RV-10 kits parts to final-sized matched holes (they are currently a slightly-undersized matched-hole design). We're excited to make this enhancement available to builders and shave some build time off their projects as a result. Details are at the link below. There's no price increase associate with this change.

Eagle's Nest Projects News - Central High School ...R.E. Butcher

Travis Senft - Central High School's 8th Private Pilot!

With guidance and support from an outstanding team of mentors, Student Pilot Travis Senft earned his Certificate of Private Pilot. The plan was for Travis to take his check ride on his 17th birthday but weather, Covid-19, and other factors beyond control delayed the flight for 7-days. Close enough, Travis!

Travis demonstrated his proficiency and professional piloting skills in a Van's RV-12 aircraft, the aircraft he helped build and the second Eagle's Nest Projects RV-12 (Falcon-2) completed at Central high school; they're currently working on their 3rd. Travis marks the 8th Central high school student to receive a Private Pilot License in an aircraft they built... pretty impressive!

Travis will be starting his junior year at Central High School in Salem Wisconsin. Travis has been on the academic honor roll since 6th grade. He is a varsity trap shooter on the high school team that has won numerous state and national tiles. Travis earned his Boy Scout Eagle Scout rank at the age of fifteen with over 40 merit badges and holds rank of Brotherhood in the Order of the Arrow. He soloed on the 4th of July 2019, his 16th birthday; and yes, before he could drive himself to the airport. After graduating high school, his plans are to become a professional corporate pilot and will be available for hire in about 5 years. Travis is a great example of 'hard work matters'. His plans are to use the rest of the summer working at the local FBO and playing with his two dogs. --->


Vibration after lift off ...Mike Howard RV-12

I have developed a strange engine vibration that occurs approximately 3 to 5 seconds after I lift off while at full throttle. The vibration started just after I replaced my nose gear leg and fork. I do not believe that it is related to an out of balance nose wheel because it does not happen until more that 5 seconds after the nose wheel lifts off.
Here is the strange part the vibration goes away completely if I pull the throttle back to about 50% for a second or two and then push it back in for full throttle. The vibration does not occur for the remainder of the flight for any throttle position.
I have checked the lower engine mounts where the new gear leg clamps to the firewall. I thought that the nuts might have bottomed on the bolt so I added a washer under the nut. The problem seems a little less but it is still there.
Any ideas?

PMag and backup generator fit ...Carl Froehlich RV-10


Yesterday I installed the production verson of the six cylinder pMag on the RV-10. Install was simple and it functions as advertised.

As many are now adding a B&C backup alternator on their RV-10 I wanted to show how both fit. This is the 20 amp B&C 410-H alternator. I suspect that the larger 30 amp B&C 462 unit may not fit as well, both for the pMag and other interference. For a backup alternator it is way overkill anyway.

Getting Warmer on the Bad 'B' Ignition on Rotax ...mwardle7

I switched the red wires from the generator in the ignition harness from the "A" to "B" plugs and vice-versa. These wires power the ignition modules. The problem moved to lane "A." It's either a wiring issue to the generator, a bad ground in the generator, or a bad stator. Hoping it's not a bad stator $$$. Still more diagnosis to do. I'm going to check the resistance of both red wires going into the harness plug to ground, wiggle the wires, and see if the resistance changes. That test may reveal a broken red wire in the insulation. If that checks out, I'll check the stator grounds, which are here (Photo provided by Brett L. at Leading Edge Airfoils):

Given how tight it is inside the cowling, I've ordered an inspection camera so I can see the stator grounds.

As a side note, I disconnected the pins for from the cockpit ignition switches, inserted two 18 ga wires stripped on both ends where each pin was removed. Then I ran the two wires into the cockpit. I started the engine and separately touched each wire on a ground in the cockpit. It was a makeshift ignition switch system that bypassed the cockpit switch system. It didn't make a difference in the behavior of the ignition, but I ruled out a bad switch or a bad ground on the ignition wires that the KAI has you ground on the bare cable clamp on the aft ignition module bolt. Note to self - get rid of the clamp and use a solder sleeve to ground the ignition wire shielding at some point in the future. The design on the clamp ground seems odd to me.




AN816 Nipple - Which One? ...fl9500

Exhaust Spring Update ...Taco RV-12

OK folks, here is more and what I did. The spring was rubbing on the exhaust tube as well as hitting the radiator shield. It was destined to fail. In addition, the exhaust ball joint was leaking, note carbon jet from the joint and on the spring, radiator shield, and welded hooks. So....

I bent out the hooks a bit. Replaced the spring and plan to wrap the radiator hose in insulating foil. Check out the clearance now. Adequate? Also re-lubed the joint with more Heavy Duty Anti-Seize. Will watch for leaking on next flight.


Don't be a Doofus like me ...NinerBikes

Had a great flight lesson in my RV-12 last Friday. Flying around a central point, full on power stalls, full off power stalls. 30 deg turns, 45 degree turns, slow speed 50 kt's keep it level almost completely power off flight without stalling.

Every thing went great. Very good, steady straight final approach, good elevation and speed management.

Made the runway, half flaps to full flaps, and chopped the throttle. Made the numbers maybe 4 or 5 feet over them. Instructor tells me again, urgently, to chop the throttle. I give the throttle a good tug, again.

This is where it got interesting.... NOT! We hit a wind burble, instructor had the controls and the plane flared up, stall horn speaks up, I am still hand on the throttle, we are about 10 feet above the ground, and the engine stopped running. Stone cold stopped. Numbers are way behind us.

Not a good situation! My instructor demanded I get a AP to fix the throttle problem. I get that signed off by an AP, it was at 1600 to 1650 rpm, Idle, warm.

Friend Bob shows me in the owners manual where Van's specifically states DO NOT PULL hard on the throttle, you can flex the arms on the throttle arm against the throttle stop and stall the engine.

I'm getting the replacement throttle springs from Van's ASAP.

My instructor called late Monday night while I was trying to schedule some more instruction hour flight lessons this week. "Different variables" had come up, and he suggested I find another flight instructor. When asked, he wouldn't go into the specifics.

He quit on me. Due to me being a student, and operator error.

Have to find a new flight instructor. His landing was perfect, even with dead stick, like a pro.

Folks, get those **** CARB springs on those Bing CARBS R&R'd, and don't scare yourself or your flight instructor with the creeping throttle problem.

Don't be a Doofus like me, and have the motor stall on you with your flight instructor... it doesn't build confidence, in the student, or the plane.


Kevin Lippert's Ceramic Coated Pipes

I had my exhaust ceramic coated by a local company, don't know the brand but they claim 2000 degree coating. Here's why I did it, reduce engine compartment heat, resist chipping and rust. The pipes are coated inside as well, and literally can touch the pipes minutes after shutdown.


Sagging engine

My 8 is showing some motor sag ( alternator pulley is touching lower cowl) after 16 yrs of hanging and 750 hrs. It's the standard dynafocal Mount with o360a1a engine. I am aware of shortening the alternator belt, but I understand that the lower bolts are a little longer than the upper bolts so that a washer can be added. Is this standard practice and how hard is the procedure? Would it be better to replace all mounts? They still appear to be in good shape from a visual perspective. If a washer is all that is needed, what part number is it?

Trimming canopy ...Jeff Wright RV-12

Hey all, I'm starting on the canopy and just curious how much did you have to trim it to get a good fit? The plans state you can elongate the canopy latch hole a tad, was that necessary? I think i may need to.

Did you need to trim the forward outboard corners? I don't have a good sense what a good trim at this location would like like.

Fuel Line Routing Update ...Tom Marshall

Thanks all for the replies and pictures. I am trying to make this work, but it's not coming easily.

Jeremy: My engine mount is a bit different. Mine has a triangular brace to the outside as well as underneath the Dynofocal cup that the fuel line has to go around, robbing it of a bit of length. After reading your post, I removed the #4 exhaust pipe, re-attached the line, and mounted the Adel clamps. In my application, the fire sleeve is fully compressed and the line itself is rubbing against the engine mount as it goes around the corner. If I relieve the tension on the hose by pulling it back in the Adel clamp so that it does not touch the engine mount, it then is stretched across the sump at the front of the engine and it is a stretch to connect it to the fuel injector

Tom: You can pass the tube under the Dynofocal cup, but there is also a piece of metal welded there so the line has to pass around that as well. Length is again a problem.

My conclusion is that this fuel line, for whatever reason, is a bit
short for my needs. My goal would be to have it routed so that does not rub against anything, and it is not under any undue tension. My inclination would be to return it for some credit and order a custom-length line.

I've attached some pictures.

Milestone, Engine hung !!  ...riseric

Long time with no updates.  I thought I could just share this as I believe it a milestone.  Engine hung today.  It was a challenge as I was alone with only my trusted engine hoist.  Tail down with no extra weight in the rear.

I had to temporarily remove the oil filter so the back could fit through the engine mount.
Then a combination of up/down & left/right moves and I could insert the top bolts, then the bottom ones which were a bit more hassle. I used a lone bolt on one side without the aft Lord mount to help align the bottom engine holes.

Once the 4 bolts bottomed-out, I relieved the hydraulic pressure from the hoist to check for balance and nothing moved, no tip over...
Between 2 & 3 small washers were needed for the castle nuts, then I torqued and installed the cotter-pins.




Initial Contact:  Aldo Perotto ...RV-7 #74830

Just wanted to do a quick "fly-by" and introduce myself. My name is Aldo Perotto and I've been working on a RV-7 tail kit since February 2020 (before the Coronaverse began!). So far I have almost finished the Vertical Stabilizer (i would like a real builder to I nspect it before I close it up) and I'm currently working on "take 2" on the Horizontal Stabilizer Front Spar ( yes, I screwed up the first one). Looking forward to any advice or pointers from the community.


What I'm Doing Instead of OSH ...RV6_flyer

Completed the Condition Inspection on my RV-6 and was hoping to take it to a Wedding in Sacramento since AirVenture was CANCELLED. Found ELT not working so it was shipped to manufacturer for repair. FAA allows me to make log entry and placard airplane "ELT not installed" and fly for 90-days. (good till 03 October 2020) Mags almost do for 500-hour inspection. Did that and I messed up timing. Test runup had CHT hit 350 F on the ground. More adjustment and now ready to test fly. Only had 2450 RPM on takeoff roll, aborted takeoff, and returned to hangar.

Adjusted timing, ground run felt better, and another test flight. Test flight had 400 CHT on downwind so pulled power and landed. Mag went in and out of airplane several times with the hope of getting it right. Ended up pulling the gear off the mag and placing it in the T-100 tool. Found that I was setting the LASAR "Speed Sensor / TDC Sensor" to the wrong side of the OFF-ON-OFF indication. Set LASAR Sensor Mag up according to the Champion LASAR Overhaul Manual and reinstalled. I have a good feeling that this will fix the issue. Ground runup was perfect. Was able to do full power (2,700 RPM) runup on the ground and have tire skid marks on ramp in front of my hangar to prove that a 160 HP RV-6 with CS prop does not weigh enough to go full power without being tied down. IF nothing else goes wrong, I can take the RV to KJAQ and attend the wedding. I believe "Time to Spare, Go by Air." I can make it but there is no margin for anything else to go wrong or any Wx delays.

Hello Southwest, I need transportation to SMF. Flew to Sacramento and back on Southwest and was able to be at my first COVID-19 wedding. Had to wear a mask in the terminals and on the airplane. All middle seats are blocked off on Southwest to promote Social Distancing. BWI terminal had LOTS of people. Hard to believe that COVID-19 slowed travel there. CLT and SMF were both light on people. CLT felt empty.

After getting home and some sleep, the airplane test flew great. CHTs got HOT but I expected them to with the power I was using and the OAT. Landed and filled up with $3.44 / Gallon 100LL. Another full power climb with hot engine to get two CHTs to 400, pulled prop back to 2,300 RPM with oversquare MAP. LASAR off so running on fixed timing mags. Watched CHTs all drop to or below 350 with 27 C OAT. Use to seeing 390 CHTs with high power, hot start engine, and higher air temps so was happy with what I was seeing.  --->




Interesting Things Seen in the Hangar ...SeanB

I always enjoy getting to visit someone else's hangar on occasion. Seeing their projects/planes is always great, but along the way, you may see something you didn't expect. An artifact, a jig, wall art, etc.

My friend and hangar mate, John Armstrong (9A), has been very busy perfecting his fiberglass items over the past several months. I admire his tenacity and pursuit of a top notch product.

Sometimes after such mundane tasks, we end up shooting the breeze around a table while enjoying a beer or equivalent. During one such conversation, I looked up and saw John's "recipe" for good epoxy. This looks like a throw back bottle and takes care of the job. Wonder if he's using Turbo, Zesty, or Classic epoxy?

What funny/interesting things have you seen in hangars?

Fuel Air Vent/Siphon (12) Update ...seagull

The air vent line had become disconnected from the "T" and the "T" was turned down. There was evidence fuel had been on the inside skin coming from the "T" . I believe that has been my gas smell when the canopy is slightly open, I'll know for sure after a few flights.

I added 6" of line and raised the loop well above the "T" intersection and zip tied it in place. I tested by overfilling the tank into the neck, the overflow drained out the bottom and stopped when the level was 2" below the cap.


Fuel line routing in an RV-7A ...Tom Marshall

I am a first-time builder, and this is my first post.

Engine: Lycoming IO-360 M1B
Fuel injector: Avstar
Engine mount: Legacy nose gear
Exhaust: Vetterman crossover

I am trying to understand how to safely route the fuel lines of my RV-7A project. I am using a VA-136 fuel line which was supplied in the firewall forward kit from Van's. It is 23 inches long with a 90 deg connector on one end, and a straight connector on the other. The OP-22 drawing that Van's provides depicts a taildragger engine mount and it states that the 7A should be similar. But, I cannot seem to route the VA-136 line without stretching it around and contacting the engine mount or having it come so close to the exhaust pipes that I don't think a heat shield would even fit.

Has anyone successfully installed this fuel line in a configuration similar to mine? I am thinking that I should return the Van's supplied hoses and order something longer.

I've tried two different routes, reversing the orientation of the fuel line for each, and neither seems satisfactory. I've attached some pictures. You should rotate the first image 90 CW for it to make sense...sorry.

Six cylinder pMag - flying ...Carl Froehlich


I installed the final production version of the six cylinder pMag on my old RV-10. I had installed a beta version, it is now replaced with this standard version that is being shipped out to customers.

Installation was very simple. On install you set the timing to whatever you want. For me I decided on MIN timing at 25 degrees BTDC (same as the mag), MAX timing at 34 degrees BTDC. I still have the standard Slick mag on the left side for now.

The plane flew home to Florida yesterday. Preliminary performance indicated measurable gains in efficiency. I'll have better data as we build time but for now some examples:
- 12K', LOP, 169kts TAS, 2380 RPM, 19.8" MP, 9.6 GPH. CHTs in the 350-360 range.
- 10K' LOP, 169kts TAS, 10.1 GPH
- 12K' ROP, 177kts TAS, 12.7 GPH

For this trip the plane was flown solo, with perhaps 150 pounds of cargo.

Updated Scat Setup ...jcarne 7A

Thanks everyone for the great response to this question, it helped me big! Pics below.

I have decided to give the method in the pics below a try with some heat shields and Dan's fiberfrax trick (I even have some leftover from the firewall). It seems that I have pretty good clearance to the number 3 exhaust pipe and about 1/2"-3/4" to number 1. If this method doesn't work I really think it will be because of the proximity to number 1. In which case I will order a muff with a different clocking that will make it a more direct shot to the inlet. Thanks again for all your help.

Carl, I'm also going to try some of your air trickery to get that heat transfer up, thanks for the suggestions.


Phase 1 report - first 50 hours...cacflyer

Greetings to all! I thought some might be interested in a first 50 hours report for my RV8. A brief history... build started in Feb 2011, first flight Sep 29, 2019 with plans for arriving at OSH unpainted with Phase 1 done. Then COVID...

My transition training with Jan Bussell went well, and the first flight ended with perhaps the best landing to date, a nice three pointer with no left over energy. I'm a low time tail wheel pilot so take off and landings have been somewhat adventurous during phase 1 and since.

Phase 1 issues encountered:

(1) loose jam nut on throttle cable at fuel servo after 10 hours - surprised by this one because I am a student of Vic's forums.
(2) oil leak at the right magneto gasket, detected by oil in bottom of cowl after flight, replaced gasket.
(3) fuel leak at the AN fitting aft side of the boost pump, detected by erratic fuel pressure readings, tighten fitting.
(4) erratic manifold pressure readings - solved by placing a rivet inside the an fitting on the #3 cylinder with a 1/16" hole to moderate the pulses.
(5) hartzell blended airfoil prop seeping grease - detected on windscreen. Turns out there's an issue if the prop sits up for a while (mine did) the aero shell 6 breaks down. Serviced the prop, took 5 squirts of the gun, and over the last 10 hours or so, seems to be slowing down (per advice of Hartzell). If it does not stop completely, I'll send it back to Hartzell for overhaul under warranty.
(6) This is an overhauled IO360 180 hp Lycoming. Now sorting out a higher than desired CHT on #2. I've reworked the baffle material the ring gear, but hard to tell any improvement since I'm now in the middle of GA summer.

That's all folks! The plane flies with no heavy wing since the beginning, very happy with the flight characteristics. If the stars align, she goes to paint on Sep 1, I've been working with Jonathan at Plane Schemer on the design, and really looking forward to the finished product, so to speak.

I'm still a bit stunned with having a plane that flies... sometimes I just stare at it after a flight in a bit of disbelief!


Abbreviated Engine Checklist ...Jim Stricker RV-12


Fuel hose torque requirements ...Bob Collins -12

Sorry to dig up an old thread, but I just happened to be reviewing 5.14 tonight with the 75-125 inch pound reference for 3/8" tubing (-6) when I noticed something.

That doesn't match 43.15

... which shows something along the lines of 120 for -6 AN818 nut.

So obviously Van is referencing something that is apparently in the Standard Handbook (why can't I find my copy), but what am I missing as to why it doesn't match 43.15?

Is it because 43.15 is geared toward the airline maintenance folks and the alloy is 5052 (because god forbid the government should recognize we use 3003)?

I'll hang up and listen.


DIY Valve Compression Tool ...BillL


Stick Changes / Elevator Stop ...Bill.Peyton RV-10

Here is how much I shortened the bottom. No changes to the pushrods, just had to play with adjustments. I also added a limit stop to the elevator.


Status ...David Paule -3B

Before I went to bed that night I glued the inner flange on, I pulled that green electrical tape off on the inside. It's purpose was to keep the black sticky 2216 glue off of the canopy. The glue had flowed over the tape, not unexpectedly, and there were some glue tentacles that remained as I pulled that tape off. I tried to keep it off the canopy but was unsuccessful. It was still in a state where its adhesion was greater than its cohesion; I couldn't pull it off the canopy where it had touched. I went to bed knowing that I'd have a real problem.

When I got the canopy back upside down the next morning and had a look inside, I thought that maybe I could grind the epoxy off. Yeah, that would work, sort of, leaving a lot of polishing ahead. But the glue hadn't completely cured. I could sand or file it, no problem, but an Xacto chisel blade was able to remove it. In most case there was no residual mark. I was so lucky. Problem solved.

On the flanges, though, it wasn't so easy. The canopy itself had been unprepared where I removed the excess glue from it. The canopy flange was fiberglass and had a roughened surface. The 2216 didn't come off there. For those, I'll have to grind them off.

3M's 2216 epoxy really does a good job of sticking to things.

In case you're wondering how the flanges and the canopy all go together, here's a sketch that I made. The flanges are rounded at their apexes but that's a bit hard to do with my drawing package. You'll have to imagine that for yourself.

For the true gurus...what is this o-ring.

I've attached a Vans Aircraft photo of inlet and outlet fitting they sell for the Lycoming mechanical fuel pump. These fittings screw into the fuel pump with a straight thread that incorporates an o-ring. I believe the same o-ring is used on each fitting.

I want to replace my o-rings. Does anybody here know authoritatively (not guessing) what spec these o-rings are.

I suspect they are either an MS29513-112 or they could be an MS29512-06. Or these could be interchangeable.

Vans doesn't seem to list these o-rings as spares. Feedback would be appreciated.

Exhaust Spring Clearance and Radiator Hose ...Tacco

I was really uncomfortable with the clearance of this exhaust spring and the lower radiator hose. So I put on a heat shield consisting of a cork and aluminum sheet. About 3/32 thick. This is how it looked at my 100 hour inspection. The spring is definitely contacting the shield and look at the heat discoloration on the aluminum. Thinking about replacing spring with the tip ground down a bit to increase clearance. What do you think? BTW turning it around so the curved radius is facing the radiator hose is worse, i.e. closer.

Second question, what is your experience with stainless steel springs?

Wednesday we awoke to BKN016, virga and 81F for a change.  It had been nine days since the last RV flight (very high temps around here keeping us indoors), so we're not going to pass this opportunity up.  Nothing fancy planned, just saying hello to some friends that live on airparks and taking a lap around the lake in mostly shade.  It felt pretty nice to get off the surface and not flirt with heat exhaustion.  That was for later on the treadmill ;^).

RV itch scratched and mental gyros recalibrated for a few days.  Back to Mt. Email a little refreshed...don't give up on me!  It's a big pile.

My RV Weekend ...Sam_B

Ok, so it doesn't involve flying or working on an RV....  But scroll to the bottom, there's a picture of my partially finished -8. And it's a couple weeks old (life's been hectic lately, but it was an 'RV weekend', just not this past weekend).

You may ask how I knew she was a keeper... shortly after we met and she learned what an RV-8 was, I was told: "well I don't want to sit in back, you have to build ANOTHER plane". I let her pick it out at Oshkosh.... and here we are.  --->

My RV Weekend ...crabandy

The RV turned a 30 minute drive into 10 minutes of getting the oil up to temp thanks to the 90+ weather. Lil' dude was all in for today's mission of helping Cindy out, unfortunately her husband flew west 7 months ago dropping his airplane off at the shop for an ADSB upgrade. When I go it'll be too soon but if I could coordinate it at the end of a flight like Gary did that would be great.

Engine miss-fire LOP diagnosis ...Wunderon

New IO-360M1B, 13 hours. Starting to investigate LOP operations. As I lean past peak (8000', around 60% power) I get continuous 'miss-fires' or 'burbling', which continue as I lean further until the engine starts to quit. Enriching back to ROP clears any symptoms.

I'm assuming injector nozzle or perhaps spark plugs. All other engine operations seem normal as far as I can tell. Mag check at altitude seemed ok, generally increased EGT but smooth running.

Avstar servo, spider, and injectors. Slick Impulse and PMAG. Checked timing, cleaned and gapped plugs before first start.

Can we tell which one or more cylinders might be causing the issue from this info?

You can see that number 2 stays pretty rich, hardly peaking, while the misfiring appears in the RPM. #2 CHT also runs higher, which I suppose makes sense. I did check the #1 and #2 probes for accuracy.

The gami spread is around 0.5 I think.

New RV 14 Build Redlands, CA
Hi everyone-
First time builder here in southern California. I got my emp kit for the RV-14A last week. Inventory went well but one of the bags was B/O and so I am unable to begin. Literally the piece I am missing out of BAG 3037 is the first piece called for in section 6. (The piece missing is the front spar doubler VS-01401).
I called Van's and they told me that the cable in the bag was actually the piece on B/O and that it should be ready around July 30. They mentioned that I might consider doing another section of the plane in the meantime. What do you think about that? I've read through the plans and it looks like I could start on the rudder and then when the B/O bag gets here in a month I could go back and complete the VS?
PS. I had intended to do a training course but as the COVID-19 virus has shut down all of these EAA classes I am unable to get that experience. I completed the lightbox project and the practice kit they send with the empanage, is there anything else I could maybe do while I wait for the parts that are back ordered?

My RV Weekend ...pgrowell

"Did some acro on Saturday."


Phase 1 at 10.5 hours ...wjb

N430WB wanted to leave the nest and stretch the wings .. after some local flights above the home field, it was time to fly south for a while .. out of gliding distance to a home field runway. Did some 60 deg steep turns, all manner of stalls (clean, half and full flaps, straight and turning, power on), worked on the envelope speed runs to 160 and 170 kts IAS in a power on dive (with some maneuvering on the way down). Most of the time was spent doing engine break-in. CHT1 was always the black sheep, running about 35F higher than all the rest (which limited the high power break in runs). After some VAF research, I decided to remove the dam in front of Cyl1 .. the next flight, all CHTs were within 10 deg of each other .. perfect!

In the end, I was seeing ~355 F CHT (plus and minus a bit across the four) at 75% power at ~6500 MSL .. sweet! (Houston, we have break-in)

Landings have been at 75kts, half flaps, which floats the landing about half of our 5000' runway. No problem at this point, but I'll keep working to bring the fence speed down. Still, the plane lands great! Lots of positive control authority in our windy and gusty costal climate.

Big thanks go to Brian, my AC 90-116 qualified pilot who helpd through the rough parts (and gave a insider's tour of the coastal landmarks during the droning parts)

Keep pounding those rivets .. the final result is a joy!


Tank Fitting Leak ...Straban

I did not build my RV 8. Doing the condition inspection and noticed this. So my question is, how is this fitting sealed? Would there be proseal on the tank side? Am I looking at removing the tank? BTW, there is also a very small weep at an accessible rivet I thought I could clean up and seal without removing the tank.


CMW E-Lift -- My take on lifting for emergency tire repair ...VAF advertiser

Those of us that travel much have all thought about what we need to fix a flat away from home. Of course we all carry the requisite tools, but lifting the airplane is a tricky part. This is my lift solution for those emergency cases. It isn't appropriate for normal everyday maintenance, and I still use a wing jack in the hangar. There are a lot of ways to skin this cat. I think I've seen most of them, but this is what gives me some piece of mind when far from home at that desolate fuel stop that had the cheapest fuel, but looks like you just landed on the face of the moon without a soul in sight.

It consists of a lift shaft, a steel bracket bolted to U-403 via some new CNC solid aluminum spacers, and a steel foot with a thrust bearing in the bottom. The bracket is plugged, top and bottom, to keep terrestrial gunk out while hopefully never in use.


My RV Weekend ...rcsilvmac

This weekend flew a friend north from Sacramento to McMinnville / Bend Oregon and over Crater Lake. Visited the Spruce Goose at the Evergreen Aviation Museum. They had a great collection with a wide variety of very nice planes as well as a space museum across the street. They did have an RV-6! Definitely recommend a visit. If you don't want to rent a car there are a couple hotels within a few miles and the museum is across the street from the airport.

Was fortunate to have nice calm winds on the way up and over from MMV to BDN, allowing us to fly close "The Sisters" and get some great views. Bend, Oregon is a great destination with a beautiful river flowing through and a cute downtown area. My first time there, but not my last. On the way back south we took a slight diversion and did some steep turns over Crater Lake. Gorgeous!


Canopy, Part 1B ...PilotjohnS

So, today was a good day. I managed to wrestle the canopy frame into submission and I think it fits well. In total, I think a good 8 hours with a 1/2" and 3/4" conduit bender should be a reasonable time to allocate for this task.

I started with the front hoop, and then did the rear hoop today. The rear hoop requires much less force; I over bent and had to unbend several times. My only advice is to realize the levelness of the top horizontal portion is caused by the side bends. The front hoop and the side rails form a rigid structure that the rear hoop bends around. The original fit of the rear hoop was really close, I just had to do a minor tweak. I did the tweak and the shape of the rear hoop became a disaster. I freaked out for about a minute and did the opposite of what I thought it needed and it all came back in line. I used reverse psychology and the metal tubes fell for it. Gosh I am good.

In summary, I started with the side rails (no adjustment needed), did the front hoop, and then the rear hoop. I think this order worked out well.

I used wedges under the side tubes and that was good. This allowed me to put on, and take off, the canopy frame all day as I adjusted the bends.

I am saying it is done. I will check the dimensions and fit tomorrow just to be sure it hasn't decided to spite me and regress to its prior mental state.

Here is a picture showing the wedges I used. I could not imagine doing this with the tracks in place.  --->


Prettiest Day of the Year ...Piper_J3

I didn't want to start a new thread, so I'll stick this here...

For about as long as I can remember I have had a compulsion to judge the weather and in particular to try to pick the prettiest day of the year.

So, this morning I fired up the 12 and headed south for a three-airport round-robin. Did all the compass points. Sparse clouds with bases right at 2500 MSL and easy to climb on top. Visibility literally unlimited. I could see the Canadian shoreline (70nm) from Northern Ohio at pattern altitude.

I think today is the prettiest day of the year so far. In the spring it's easy to pick a good day; no rain - good day. As the season turns to summer, it's a subtle difference that allows the current day to outshine all previous days. Today is that day...

Van's Airplanes: Is there anything they can't do?  ...Dgamble

Just about a year ago, I was sitting at the departure end of runway 22 at Bolton Field (KTZR) in my RV-12 preparing to launch on yet another $25 hamburger run ($100 hamburgers are for Lycomings and Continentals) when I got to thinking. I have over 1,000 hours in my logbook, 355 of which are in the 12, I have an IFR rating that hasn't been current in over 15 years, and a growing sense that I might be becoming dangerously complacent.

I started to think that I ought to find another form of flying that would instill more professionalism and purpose in my flying. I had also recently made a new Facebook friend who just happened to be the Major in charge of a local Civil Air Patrol squadron. We will call him Maj. Joe. I had never paid much attention to CAP - my perception of it was that it was basically Boy Scouts that guided me to a parking spot at the Dayton Air Show, and were nowhere to be found after the show when 100,000 cars all tried to leave the parking lot together.

I ended up giving Joe a ride in my 12 and during that ride he disabused me of that perception. While there are obviously a whole lot of CAP cadets, it turns out that there are also what are known as Senior Squadrons. Those squadrons are all adults and airplanes. It also turned out that there was just such a squadron based right up the road at Don Scott (KOSU) airport, and he was the Squadron Commander. He painted a very intriguing picture of that part of CAP and invited me to sit in on a meeting or two. Just about a year ago, I joined.

A year later and I have yet to fly a CAP airplane. Covid and other factors have kept me out of the airplane (a gorgeous Cessna 182T, G-1000 equipped), but I have undergone a lot of training. There are three positions in a CAP mission: Flight Commander/Pilot, Observer, and Scanner. The pilot is not necessarily the Flight Commander, but usually is. The Observer is the right-seater and responsible for operating the radios and search equipment. The Observer does not have to be a pilot, but it helps. The Scanner is in the backseat and is the only crewmember tasked exclusively with looking out the window trying to find the target, whatever it might be.

Maj. Joe flies with me in the 12 quite often now. I have him trained up enough that I will let him fly from the left seat on one of the legs on our flights. We made such a trip yesterday. We were flying down to Jackson Co (I43) to pick up a Koger sunshade that I bought used from Phil Boyer. I flew left seat on the outbound leg, so Maj Joe was in the left seat as we climbed out on our return flight. As Observer, I dialed 121.5 into the Comm radio and set it to Monitor - a habit Maj Joe had instilled in me.

We were immediately hit with the squeal of an ELT. It was a very strong signal, and as the area around Jackson is very rural, my first thought was that the source must be located on I43. Without a Becker system (basically an ADF that points at ELTs) we didn't have a solid indication of where the beacon could be.

Having just finished Observer training a couple of weeks ago, I knew about a technique called "wing null." It's very intuitive - you roll the plane into a fairly steeply banked turn and listen for the ELT signal to be blocked from the comm antenna by the wing or fuselage. The comm antenna on the 12 is down on the bottom of the fuselage, so the moment the ELT signal was blocked I was able to look up through the canopy in the direction of the signal. Sure enough, there was I43. Having narrowed down the source sufficiently to assume the beacon was at least in the neighborhood, we called Flight Service and reported it.

This morning our squadron (OH-085) was tasked with confirming the location of the ELT. They did so, contacted the airport manager, and within half an hour the beacon was found and silenced.

The cool thing is not just that I will be awarded the privilege of wearing a "Find" ribbon on my uniform, the airplane that found the beacon is also qualified for the ribbon. I might have the unique distinction of owning the only RV-12 that can wear that ribbon (in the form of a decal, of course).

When I say "Mission Accomplished," I'm not talking about the find. I am referring to using my airplane and license for something much more rewarding than an airport hamburger.

First Family Flight

Took the family up for the first time in the -10. Each of my wife and two kids had flow a few times with me but not as a family to stretch the legs a little on the -10.

In-laws live in Prescott, AZ so off we went Saturday Am, departing KSEE about 8:00am arriving about 1.9 hours (6.5 hours drive). SPent the night and flew back this morning.

Great first family trip.


Question on Location of ADAHRS in Relation to Static Port ...PhatRV

I am relocating my ADAHRS to a place that is easier to maintain. However, the location of the ADAHRS is lower than the location of the static port. The embedded picture below shows the relative location of the ADAHRS and the static port. The static line is tee-off from a location near the top longeron to mitigate any moisture condensation and runs forward to the front panel. The static line is tee again downward toward the ADAHRS, and its location is slightly lower than static port in level flight. When the airplane is sitting tail down, both are located at about the same level.

Question: Is this location acceptable in term of mitigating moisture condensation with the distance between the static port and the ADAHRS is about 36inches? Are there other problems with this setup? Thanks.

  The move of VAF data from its Windows-based server environment to a Linux-based one will occur soon - if not this weekend then almost certainly sometime next week.  Final testing underway now...  This will fix an email notification issue, will allow turning on image hosting options that didn't exist before (Yes!!!), will bring background software up to a newer, more stable versions and other big words from the tech bullshit generator.
  What does this mean to the average reader?  Probably nothing, it's possible you might not even notice it happened.  I'm saying all this that on the chance you can't get into the forums or front page for a few hours, that's probably the reason.  It takes time to move 1.1 million posts, change DNS entries, and have that propagate around the globe.  Thanks again to VAF user 'bkervaski' for his help with all this.  That guy knows his bits and bytes!  Built a dang nice RV too...
  Wishing you and yours a happy, safe and RV-filled weekend.

RV-8 landing attitude ...lucaperazzolli

An evening team formation training flight gave the opportunity to a photographer to take this shot. It's a picture itself that took my attention thinking to high level of concentration needed in this particular moment. A couple of words about my tail that probably seems too far from the ground, against the perfect "two and a half points" attitude as Vans says. I'm leading a landing of two planes and giving my friend more room needs more ground roll speed. I love how you can manage the RV as you need, it is balanced, quick, solid and a grin maker as a rule.
ps: in the background you can see the HomeBase of our Mountain Search and Rescue team, great guys are there !


High Oil Temp when Coming in to Land (Long) ...Darren Kerns

I have been experiencing an high oil temperature indication when coming into the pattern to land. I have AFS 3400s screens with engine monitoring sensors.

My oil temperature sensor was replaced at 310 hours and now may have to be again at 344 hours. During climbout and cruise it seems to be indicating fine. It is running a little warmer but it has been extremely hot here.

I called Rob and he told me to check of my wiring to and from the engine. So tonight my wife pulled both cowls and checked the engine ground to airframe wire. It had some oil on it but I cleaned it up and refastened. No crimps were lose. I checked all wiring to & from the alternator it seemed fine. Nothing lose. I then climbed underneath the panel and check breakers, crimps, and wiring and found nothing lose.

Rob suggested I turn off the alternator field and see what it did. My oil temperature was indicating 266 degrees and when I turned it off, it dropped to 187 within seconds. It seems I have some type of electrical interference.

I am getting so frustrated because I do not know what else to look at.

Can anyone help me to look at something else I have not thought of? I am going to order a new oil temperature sensor from AFS. However, this may not fix the problem.

Sidenote: When I replaced it back at 310 hours it was doing the same thing. I installed a new oil temperature sensor and it fixed the problem.

The other day when I was flying my 7 my oil temperature jumped to 366 degrees & then dropped to 204 within 2 seconds. This was without me turning my alternator field off. This is impossible for oil temp to change that much in 2 seconds.

Please, if anyone can give me some advice I would greatly appreciate it.


Social Distancing Airshow ...tcard's July 4th weekend

The airshow season has been pretty quiet this year. Falcon Flight performed in Laredo in February before the madness started, but the rest of the spring shows were canceled.

Normally each year around July 4th, we are part of an airshow over the Cedar Creek Reservoir located southeast of Dallas. Until just a few weeks ago the show's status was in question, but the organizers decided to move forward. The vast majority of spectators are in boats - so socially distancing among groups was possible. They normally have a large crowd on the shoreline by the club house, but that was scaled way back this year. it was a hazy afternoon with the Saharan dust, but the afternoon show went well.

My first ever 'social distancing airshow'.


A Good Reply on Nomex and Cotten ...krwalsh

[ed. A reply in a 'First Flight Clothing' thread.  v/r,dr]

Nomex & Cotton
I've been on fire once before in my life (not in an airplane) and it is not something I'd wish on my worst enemy. So for my first flight, I went with the following:

Nomex Flight suit. Search eBay for a new old stock one and save some money.

Long sleeve cotton shirt underneath. You can buy fire resistant (FR) shirts from quite a few places too. I ended up getting an Oakley FR Carbon-X shirt for some of my flights, but only because I was flying faster than I could do laundry for my long sleeve cotton shirts, and I was flight testing in the middle of summer and would soak my shirts in sweat.

Lightweight, but calf-height wool socks.

Nomex high-top shoes. You can get them from the race shops online (Pegasus Auto Racing is one of my favorites). I have Piloti brand, but Simpson sells similar ones.

Leather gloves. Thin TIG welding gloves are great low-cost alternatives.

I wore a helmet (MSA Gallet), but no parachute. That's an entirely different discussion on those choices.

That's it. After my flight testing was done my flight suit and shoes have pretty much been sitting in a bag at the hangar. Everything else you can use in normal circumstances.

Mag Check Issues after Installing New Cylinders ...Dan Langhout RV-7

So I am about out of ideas. I have an Aero Sport Power IO-375 (Precision Airmotive Silverhawk FI / Lightspeed electronic ignition top and Slick impulse mag bottom) with almost 600 hours since new. Oil consumption rate has never been great (~ 7 hr/qt at best) and in the last year or so it had increased to 3-4 hrs/qt. I decided that at this annual, I would replace the ECI Nickel-Carbide cylinders with genuine new Lycoming Nitrided cylinders. Did the cylinder swap and now have about 11 hours on them - all following the recommended break in protocol (75% power etc, etc.)

Problem is, ever since the cylinder swap, The magneto really doesn't pass a mag check at full rich mixture. EGTs all climb, but can be erratic. This is a change from the previous 600 hours. Leaning the mixture improves it significantly. In flight mag checks look good. The engine runs fine on either ignition (at least as well as any engine runs on one ignition). Of course the mixture is leaned normally during the in flight check.

Given that the mag check on the Lightspeed was still fine, I made the assumption it was some sort of mag ignition system issue. Short version is after swapping plugs, a new ignition harness, and even swapping out the mag, the issue is still there. Lower plugs basically come out black and somewhat wet looking.

Beginning to think the problem may be with the Silverhawk injection running too rich under typical run-up/mag check conditions - but that would certainly be a big co-incidence in that it just happened to develop the problem at the same time as the cylinder swap.

In looking for what items were "touched" during the cylinder swap, all spark plugs and leads were obviously moved, and the individual injectors and injector lines were removed and re-installed. If trash got into the injectors while they were out, I would expect lean issues - not rich issues. The magneto itself and the rest of the injection system were not touched (other than removing the "snorkel" where it bolts to the front of the fuel servo).

My next steps will be to do some of the recommended trouble shooting procedures for RSA type injection systems (injector volume flow test, etc.) but failing that - I am at a loss.

Any ideas?


Baffle inlet seal question ...jcarne RV-7A

As you can see in the pic below I have a little gap between the air filter and the inlet baffle seal. How would you guys address this? Is it even necessary or will the air pressure seal it up? I though about putting some proseal or something on the filter rubber but I'm worried it won't stick to it. Thanks for your thoughts!


It's Always Something Gilda... ...Jim Stricker RV-12

Just some random thoughts while sheltering-in-place...

Remember Gilda Radner from Saturday Night Live? She used to say "it's always something". I kind of adopted that philosophy with the RV-12 that I bought flying from original builder. I have owned 633CM now for almost 5 years and 500 flight hours and "it's always been something Gilda".

So, why am I writing this? Not complaining one bit. All the labor and time spent has been a wonderful learning experience and the plane is safer today than ever before. I have learned the airplane intimately. I think I'm finally done with SB's, addressed everything on my squawk sheet, done tweaking and polishing, and even the hanger is cleaned out. Having said all that, I'm probably setting myself up for a major maintenance event.

It feels good to just drive out to the hanger and go fly. The 12 is such a nice design for both owner maintenance and its wonderful flying characteristics. Control harmony and light stick forces, wide cabin with ergonomic seating, excellent visibility, modern avionics, 5 GPH Mogas, 130 MPH cruise, 1000 FPM climb, and 550 lbs. useful load. Couple all of that with the 12 being eligible for Repairman (light sport) with an Inspection Rating (LSRI) and it just doesn't get any better.

I've been flying for 50 years. My father taught me to fly when I was in high school. Dad and I owned a Cub for 23 years. I traded the Cub for the 12 and never looked back. My father passed on July 9, 2006 and never got to see or fly my 12. He would have been amazed. I have his Air Force Wings proudly displayed on the instrument panel. I flew one hour this morning and passed over Ohio Western Reserve National Cemetery and dipped the wings...

So, now we have COVID and everyone is flying solo.

It's always something Gilda...

Rebuild Update ...jamlip RV-6

Latest update on this treacle-paced project...

Made a manual trim bracket. I never liked the flimsy centre console setup in the RV-6, so I re-routed the cable and figured I'd mount it sideways, so the knob rolls forwards and back, like a mini version of the trim wheel in a spam can.

It has taken me the best part of a year to commit to this design. Here is the bracket, and here is how the cable is now mounted. The bracket is mounted using two of the wing spar bolts.


Unbalanced elevator heavy on the ground ...Lufthans


Picking up my new-to-me RV-3B in Germany turned out to be quite an adventurous two-hour flight. The prop had so much imbalance in it that anything over 2100 rpm felt unsafe, after 5 minutes of flight the throttle came loose from its cable due to the piece of wire that was supposed to imitate a cotter pin parting ways, leaving the pin free to fall out, and to top that off the MGL engine monitor turned to reading very improbable (yet very unnerving) values for oil temp, oil pressure and EGT.

Returning to field of origin not really being an option due to narrow runway and a stiff crosswind making my upcoming dead-stick first ever landing in an RV3 less appealing than heading home and landing on our generous 3000' x 3000' grass airfield, I continued the flight. Juggling the throttle cable by reaching over the quadrant, pulling on the 3/4" of exposed cable with my middle and ring finger against the spring in the carb that wanted to pull to a highly vibrating full-throttle the whole time, in happy anticipation of the inevitable landing.

In short: my observations regarding control feel have been overshadowed somewhat by events. And after safely (dead stick) landing at my home airfield, the first thing I have done is take the plane apart for a FULL rebuild (despite the thing only having logged 34 hours total time since new).

What I recall though is that the elevator really felt heavy on the ground. It felt nothing like the lightness of an RV4 (which of course has a balanced elevator), and also a lot heavier than my Jodel or Fly Baby (which haven't). More akin to the feel of the T6 that I fly on occasions. Like you really need to put some muscle in keeping the stick pulled while taxiing.

This alone makes me consider balancing the elevator.

Or has my memory been blurred and are RV3 stick forces on the ground really not that high? Everything was moving freely, nothing binding. Just felt like somehow I had to lift a lot of elevator.

Altitude Puzzler: Discrepancy between altimeter and Mode C readout

I recently was in IMC in light turbulence. I experienced a brief excursion to 6160'. ATC informed me that my transponder indicated flight level 063 and generated an automated pilot deviation. I'm puzzled why there would be such a discrepancy and looking for ideas how to prevent reoccurrence.

I'm flying a recently completed RV-7A with a Dynon HDX EFIS, IFD540 GPS, and Dynon transponder, ADS-B in/out, ADAHRS and pitot-static system.

As I understand the system operation, the ADAHRS receives a pressure on the static port input and reports it to the EFIS. The EFIS adjusts based on the barometer setting and displays my altitude MSL. It also records the pressure altitude (relative to 29.92) in the EMS log. It sends this pressure altitude over a serial link to the transponder, which broadcasts to ATC, who in turn corrects based on barometric pressure to generate a 3-digit flight level on the controller's display.

In my case, I had been given a barometer reading of 29.73 11 minutes prior to the deviation. My engine logs show a maximum pressure altitude of 6351' at the time of the deviation. This corresponds to 6351 + 1000*(29.73-29.92) = 6161' MSL, in accordance with my recollection of what was displayed on the EFIS.

I expect the same 6351' pressure altitude should have been broadcast by the mode C transponder and ATC should have corrected it to read Flight level 062. However, Center sent me a picture showing me at 063.

Given the digital communication paths, I don't see how there could be a calibration error that would cause the pressure altitude recorded by my EMS to be different than that received by ATC. And the only way the altitude displayed on my EFIS would be different than that displayed by ATC would be if we were referencing different barometer settings. The pitot-static system tested within spec in January, and even if it had an error, I would think it would affect the EFIS and transponder identically. To the best of my understanding, my altitude seen by ATC comes from my static system and transponder, not a geometrical altitude from my IFR GPS and ADS-B. My ADSB also recently passed its PAPR check.

I'm pretty confident that I read back and entered the correct barometer setting shortly before the deviation. But I'm puzzled what else could cause this discrepancy and whether the problem might reoccur in the future. Maybe I misunderstand how my altitude is determined for reporting to ATC? Any other ideas? (I don't know the answer to this puzzler...)

Thank you,

Milestone: Windscreen Glued On ...Jereme Carne RV-7A


Failed mechanical fuel pump field fix

Just experienced a failed mechanical fuel fuel pump discovered at a fuel stop at a relatively remote field.

The pump still made good pressure but the leak rate was way too much to fly it.

Turns out that the KB fittings that most of us use to route the in/out fuel lines into the pump have the same 9/16-18 threads on both ends. Remove this fitting from the pump and it can be used to connect the in/out lines together, "jumpering out" a leaking mechanical pump.

You can then make it to civilization using the boost pump to fly, assuming you have a reliable electric boost pump.

Hope this helps someone in a jam.

(more info from a later reply)

...one of the fittings on my pump had a flare on one end and a flare with the o ring boss on the other end - nice!

Bobby, yes, the folks at this very small municipal field always come out to pump and they noticed it. I would probably have caught it as it takes a minute or so for the fuel in the system to back flow through the leak. It also is enough to leave a significant puddle.

I had always thought that a pump diaphragm failure would cause a small relatively insignificant leak. In this case the leak was estimated to be a gallon in four minutes at 1400 rpm during a subsequent ground run up. Needless to say, that was un-sat for further flight even though the pump was still making 25 psi!!

This happened at the end of a 2.5 hr cross country. Not sure when it started or how fast it leaked in flight, but I estimate 1.5 gallons were lost in flight using totalizer data. Engine never missed a beat.

My RV Weekend ...Planecrazy232

On 7/3 I took on the task of replacing my old sagging engine isolators with new Lord mounts. Scored a new set on the auction site for 300 bucks! I would rather have a root canal than to do this again! My bolts are the old style that use castle nuts and cotter pins. If I was to do it again I would definitely get the new bolts with the steel locking nuts. Went for a flight afterwards and it was smoooth!!  --->


Tank to wing leading edge gap ...TG777 RV-14

Plans say" The edges of the T-00001 Fuel Tank Skin must have a zero to 1/64 [0.4 mm] gap between the adjacent wing skin edges. A larger gap may be desireable if the aircraft is to be painted, while zero gap may be desireable if the aircraft is to be left in natural aluminum." Right now I have zero gap with a very tight fit and it looks great. What potential problems are there with leaving this a zero gap vs filing edges to make a gap for a painted wing. My concerns would be a lack of expansion space and its effect on cracking paint.

This is mostly about easing removal of the tank if ever necessary.
Some paint shops put paint and clear coat on so thick that it can be difficult to remove the tank without damaging the paint.
With a gap, the paint can be more easily scored/cut if tank removal becomes necessary.


Got it! ...JFCRV12

My RV-12 is home Tomorrow, I'll be getting checked out in it (insurance requirement).

Such a cool machine. One new squawk on the transport to Ohio from Sacramento that I need to sort is the right strobe light isn't working..but the nav light does. I suspect it's a loose connection at wing root.

Then, I need to start the wheel pants and get em on to get her 'prettier'

4th (and 5th) of July RV Formations ...ChrisF16

A bunch of us in the San Antonio and Austin area did some flyovers for events in the Hill Country around Comfort, TX this Independence Day weekend. I temporarily traded my RV-4 for the SNJ but was joined by several other RV owners and a Nanchang CJ-6 in flyovers on Saturday and Sunday.

Every aircraft was flown by USAF veterans.  ---> & video


4th of July Formation Tributes by the KFFC RV Squadron ...rswalden

Lots of patriotic formation flyovers this weekend by our Falcon RV Squadron.

But this has to be the winning photo...Don Roberts is the "missing man" in this flight, "heading west" in honor of all who have given their lives in service of others.
This photo was taken at our Peachtree City Hall... under a giant "Heart of Thanks" that the flight previously created.

At the same time, two other of our RV flights were performing identical tributes over the historic courthouse flags in Newnan and Fayetteville.


19 aircraft flyover ...intothinair video

On Saturday July 4th, the Norcal Beechboys and the Memorial Squadron performed a combined flyover of 19 aircraft over Buchanan Field (KCCR). Aircraft participating included a group of 12 Bonanzas, a Beechcraft Mentor, a T6, a Marchetti SF-20, a Pitts, and one each of a Van's RV6a, RV7, and RV8.

One More July 4th Celebration....the Sound of Freedom ...39sec video

Randy Richmond (RV-8) video of the B-29 'FIFI' flying over our home field 52F on her way back to Meacham airport (KFTW) Sunday 4:30pm.  FIFI participated in the flights over the Mall in D.C. on Saturday.  I could just barely see it off in the distance just above the trees from my house, and another friend said it went just north of his house.  Monk got the best view, though - show pass over the field due to it being almost exactly on the straight line from the fuel stop to home base.  Dang.

The Van's RV tie in?  The guy in the left seat of FIFI flies an RV-8 ;^)

Happy Birthday America, turn that volume up and have a nice week.

PS:  FIFI got back at the right time.  An hour later the pop-ups started and a bunch of folks started doing laps.


Sec 46 Step 2 Getting Hosed ...RV-12iS

So step, or maybe it's 3, calls for removing the preformed radiator hose. Move the spring clamp. Tug. Tug some more. Nothing. Couldn't get any sign of its interest in being disunited from her friend,, the engine.

There is, of course, very little room to work. Has anyone encountered this and how much do I want to manhandle the poor thing?


Surface Tension/ Riblets / Laminar Flow  ....just read every reply and learn as I did.

(It started with this post)
Surface Tension - Aero Drag
Back in the day, I raced RC boats. We used Imron paint over carbon/kevlar laminates to finish the boat. The first time I took my bright glossy boat to the lake, it would not get up on plane. This was a proven design that would go 100 mph. I was stumped and started looking at engine and drive train. Then someone came up to me and said "Your boat will never get up on plane until you scuffed the bottom of the boat". I said "I just spent days prepping and painting this thing to get it perfect." He replied "Well, it will make a nice looking bouy until you scuff the bottom of the boat.
Eventually, I gave in. The boat immediately took off on plane. I went home and did some research. He was absolutely correct, the shiny paint finish on the bottom of the boat was allowing the water to just grap the boat with surface tension.
My point to all this is, does this apply to air over a surface?
Eventually, I scuffed the top of the boat as well to reduce aero drag and picked up 8 more MPH.
Interest to hear if anyone has experimented with this? The closest thing might be a painted plain vs an unpainted plane. As most do not paint until the 40 hours are flown.

Advice on conical bend rivets? ...mattasmith12

Happy 4th all,

Hoping for some advice. How did you tackle the transition where the conical bend from the forward side skin matches with the aft side skin. These two skins don't transition smoothly and there is a wedge-shaped gap between them.

The build manual is lacking in detail. I've scoured builder threads and haven't really seen how to handle this. I know just driving rivets will cause pretty large dimples. I could fabricate wedge-shaped shims to take up the space... Any tips?


Torquing engine bolt in tiny space ...RV-12iS

What is the tools-combination-of-choice for torquing down (or even threading it beyond finger tight) for the top left Allen bolt where the cylinder gives you all of about an inch or two of access on the Rotax 912iS?

I was thinking of cutting down an Allen wrench to next to nothing, then using a crows foot in a rachet but perhaps there are more elegant, less tool-destructive solutions.


Firewall Fwd Continues ...jcarne

Got the PCU5000 on Friday from the VAF group buy, thanks VAF members who ordered! I was worried this was going to be difficult to install with the engine already on, it was probably the easiest thing so far! Plenty of room to work back there. I could even get a torque wrench on all the nuts! You can do almost all of the assembly with it swung out of place, then just put it on the mount with the gasket and torque it down.  --->

In Congress, July 4, 1776.
The unanimous Declaration of the thirteen united States of America, When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world.

He has refused his Assent to Laws, the most wholesome and necessary for the public good.
He has forbidden his Governors to pass Laws of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, he has utterly neglected to attend to them.
He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only.
He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their public Records, for the sole purpose of fatiguing them into compliance with his measures.
He has dissolved Representative Houses repeatedly, for opposing with manly firmness his invasions on the rights of the people.
He has refused for a long time, after such dissolutions, to cause others to be elected; whereby the Legislative powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within.
He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws for Naturalization of Foreigners; refusing to pass others to encourage their migrations hither, and raising the conditions of new Appropriations of Lands.
He has obstructed the Administration of Justice, by refusing his Assent to Laws for establishing Judiciary powers.
He has made Judges dependent on his Will alone, for the tenure of their offices, and the amount and payment of their salaries.
He has erected a multitude of New Offices, and sent hither swarms of Officers to harrass our people, and eat out their substance.
He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures.
He has affected to render the Military independent of and superior to the Civil power.
He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his Assent to their Acts of pretended Legislation:
For Quartering large bodies of armed troops among us:
For protecting them, by a mock Trial, from punishment for any Murders which they should commit on the Inhabitants of these States:
For cutting off our Trade with all parts of the world:
For imposing Taxes on us without our Consent:
For depriving us in many cases, of the benefits of Trial by Jury:
For transporting us beyond Seas to be tried for pretended offences
For abolishing the free System of English Laws in a neighbouring Province, establishing therein an Arbitrary government, and enlarging its Boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule into these Colonies:
For taking away our Charters, abolishing our most valuable Laws, and altering fundamentally the Forms of our Governments:
For suspending our own Legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever.
He has abdicated Government here, by declaring us out of his Protection and waging War against us.
He has plundered our seas, ravaged our Coasts, burnt our towns, and destroyed the lives of our people.
He is at this time transporting large Armies of foreign Mercenaries to compleat the works of death, desolation and tyranny, already begun with circumstances of Cruelty & perfidy scarcely paralleled in the most barbarous ages, and totally unworthy the Head of a civilized nation.
He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country, to become the executioners of their friends and Brethren, or to fall themselves by their Hands.
He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions.

In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free people.
Nor have We been wanting in attentions to our Brittish brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which, would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends.
We, therefore, the Representatives of the United States of America, in General Congress, Assembled, appealing to the Supreme Judge of the world for the rectitude of our intentions, do, in the Name, and by Authority of the good People of these Colonies, solemnly publish and declare, That these United Colonies are, and of Right ought to be Free and Independent States; that they are Absolved from all Allegiance to the British Crown, and that all political connection between them and the State of Great Britain, is and ought to be totally dissolved; and that as Free and Independent States, they have full Power to levy War, conclude Peace, contract Alliances, establish Commerce, and to do all other Acts and Things which Independent States may of right do. And for the support of this Declaration, with a firm reliance on the protection of divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.

Tested out my Flyleds combo lights today ...N546RV

It's been a while since I assembled these units and gave them a nighttime test, but today my wigwag controller arrived, which of course necessitated another test. This time I decided to set both lights on a table out on the ramp, pointed down the runway. Then I went to the far end (~3/4 mile away) to "evaluate."

Yeah, pretty sure people will be able to see me. The video doesn't do it justice.

Also, on my return trip on the golf cart a neighbor flagged me down, and we chatted a bit. At one point he commented that I wouldn't be able to log night currency with these on the plane...

And one final note...a few months ago, I was tying myself in knots trying to figure out how to include the fourth tax-light projector in the wigwag circuit, and folks told me that the three landing projectors would be just fine. They were definitely right.

RV Build - Take Two ...Tim Foster

After selling my last project I had immediate sellers remorse. Basically before it was out of the driveway.
So about a year later I begin again. This time with quite a bit of head start thanks to a great builder in Colorado.

My RV-14A project has begun - or at least the waiting stage. It's at the QB stage in wings and fuse and the emp is done. Now I'm waiting for shipping- hopefully sometime in April.

I am passing the time organizing the shop and building a bench and wing stand. This time opting for the shorter wing stand that doesn't take up as much shop space.

My wife will remind me not to sell this time as I have promised her some good cross country flights at some point.

My wife (Sha) is very quiet for the most part. But she is the one that prepares everything for the annual RV ice cream social. She also funds it. The event has been very successful and has allowed for our RV community to flourish with new friendships and continue the on going ones.

She is also one of the people that helps during the RV formation clinics. Check-ins are her deal. Paper work better be right or you ain't flying.

So if you have a moment and can wish her happy birthday or share an experience of how the events are meaningful, it would be appreciated.

Another 'Getthereitis' cautionary tail, ground version ...flion

This has been an exhilarating month. Since being released from a heavy teaching load thanks to the CoV-2 strain, I've finally been able to get to the panel change on my RV-6A and have accomplished more in the past month than in the previous two years. In fact, I have finished the work, done the G3X calibrations, and completed a condition inspection so the aircraft is ready to fly. But I'm not, and I'll explain the symptoms that convince me that I need to cool off a bit before taking to the air.

Two days ago, I finished connecting all the FWF sensors. The CHTs and EGTs had previously been connected and tested, as has been all other peripherals to the G3X system. Everything had been flawless so I was not expecting problems but a test showed that the oil temp sensor was not reading. I checked the connections - all good. It was the same sensor that had been there before and looked identical to the one shipped with the G3X, but I was tired so I figured I'd come back the next morning and try the new sensor. Fortunately, overnight my brain reengaged, so before swapping the sensors out, I checked the configuration and tried changing from the default to a K-type sensor and magically it worked. Ok, not too serious, but it's the beginning of the curve.

The rest of that day, I put the tank/wing root fairings back on, since there were no signs of leaks other than a dripping sump (replaced O-ring, problem fixed), buttoned everything up, and pulled it out to try an engine start. About when it should have started I got two backfires in succession and then the prop wouldn't turn. With not enough battery, I put it on the charger overnight. My guess (wrong) was that I had flooded it and didn't have enough battery to try a hot start procedure. Trying again in the morning again gave me backfires and eventually the prop would not turn, until I attached a boost battery - but you could see it straining at times. Now, finally, the brain wakes up - it acts like the lightspeed ignitions are out of phase. I had tested those before, but I would pull the top plugs to test again.

The procedure is to rotate the prop rapidly by hand back and forth across TDC. The plug wires are removed from the coils (and the top plugs are out), so there is no danger of starting but you will see a spark jump the coil outputs each time the prop moves past TDC in the right direction. Which coil sparks for #1 TDC also tells you which coil to connect #1 and #2 cylinders to. Repeat 180 degrees off to spark the other coil for a 4-cylinder engine. But, as I prepared to test the phase, the brain finally fully wakes up and reminds me that the marks on the front of the flywheel are different than those on the back. Yep, I had connected them out of phase but it was an easy fix to swap the coil connections at the lightspeed boxes.

After that, the engine started normally and I did a run-up and tested the engine and prop controls. Then I re-buttoned up the cowling, restarted, and taxied out to the compass rose to do the magnetometer calibrations. The magnetic interference check was no problem, so I restarted to do the compass swing, but there was too much airframe movement with the engine running so I shut down and called a friend to help run the calibration while I used my towbar to pull the plane around the circle. No problems and afterward I went to start the engine to taxi back but no joy. Even the hot start procedure did nothing.

Rather than run the battery down again, I pulled the plane back to the hangar with the towbar (fortunately not far) and put it back on the charger. When asked if I was going to fly it, I declined, preferring to wait until tomorrow when (I hoped) the engine would be in cool start condition again. It was not until I was on the way home when I realized what the trouble had been. With my mind on all the other things involved in completing the condition inspection, instrument calibrations, etc., I had forgotten to push the fuel purge control back in (AFP injection). My mind was clearly not 'flight ready' and I was not using my checklists or thinking my procedures through on something 'as simple as taxiing back to the hangar.'

So, beware tiredness, excitement, or other conditions that can lead to mistakes, even while building, or maintaining, as opposed to flying. We've all heard stories of people who left off a cap or forgot to safety a fastener or some such but we tend to think 'not me!' I did not realize how far away from flight ready I was until I reflected on the events above. But now I'm aware and I'm pulling out my POH to review procedures. More importantly, I will have the checklists in hand before I operate the aircraft again, rather than cavalierly assuming I know them well enough for ground operations. If you've had a bad building or flying day, maybe you should rethink your headspace, too.

Mobile Plans Relocating Device (Cheap Lectern to hold plans) ...Packetpusher

While working on the RV-14 HS and rudder, I quickly realized that I spent roughly 10% of my time deciphering what the plans were telling me to do and 15% of my time finding a good place to lay out the plans so they were convenient but not in the way. I figured there had to be a better way. I couldn't find anything free, but I did find this inexpensive wheeled lectern on The Amazon. TLDR; this might be the greatest addition ever to my shop. I don't know how I could live without it. I'm so in love with this thing that I had to share how wonderful and life-affirming it is.

There are lots of styles available for around $60-$80 brand new. You might even be able to find one used if you have a local church going out of business. It holds the plans at the perfect height to read while standing or even sitting on my shop stool (get your own stool) and the angle makes it easier to read than on a flat table. There's even a small lower shelf to hold my cup of rivets before I spill them. I can wheel it around to always be nearby no matter what area of the shop I'm working in. As a bonus I'm always ready to deliver a sermon to anyone foolish enough to enter the shop asking about airplane building.

Assembly was really straightforward and my contract labor was able to get everything put together in about an hour (see below). I'm thinking about future upgrades to include LED reading light, ground effect lights, Blue Sharpie holder, holder for inferior pens, insulated beer caddie and airbrushed flames so it rolls faster.  --->

Building Advice ...alwaysoutdoor

I am hopeful that this may help someone who is about to start the building process

I am on my 3rd Rv-7. The rv-7 is extremely easy to build if you enjoy building: I found out early on that I enjoyed building just as much as flying. Don't think of it as an airplane until you have the paperwork signed in your hands- think of it as lots of little fun tasks that you get to be lucky enough to be a part of. As a young adult I had all the time in the world after work, between classes, on weekends, before parties, in the middle of the night, etc. so I got a little carried away with putting too much time in on the project. I finished the tail in just a few weeks but probably was only sleeping 3-4 hours a night and my 4.0 gpa turned into a 3.6 almost instantaneously.

The big mistake I had with my first plane is that I didn't budget anything. I was being a perfectionist and wanted top notch everything so I quickly realized I had to sell it before I had to drop out of college. (I really was at the point where it was "finish the last 2 years of college or buy the extremely expensive avionics I was drooling about" ): still don't know if I made the right choice ;-).

The second rv-7 I built was a few years after college. Still no kids and no wife. I did it the opposite way completely when it came to money- I tried to get everything I wanted in a plane but wanted to build it where I could actually afford it. I bought everything I could second hand (which ended up to be just about everything) and budgeted everything like a crazy person. I ended up finishing it with a 0 time smoh engine and beautiful Harley Davidson copper/orange and black paint and glass panel for just under 45K... this plane would have cost about 90K-95K going with brand new kit and components (searching classified ads and PMing people on this site really makes that much of a difference)... saved me 45K over the 2 year build process.

I made myself only work on it 1 weekend day a week so I still had a life with dating and hanging with friends after work.. I put in 18-20 hours in that 1 day though and think I pissed off the local wildlife by riveting early in the morning and past 2am as well. Never lost a chicken to the owls, coyotes, raccoons, or bobcats on those nights!

Now I have 2 young kids (1yo and 4yo) and sold that plane last summer after flying it for about 6 years and bought into a partnership in a 182. After buying part of the 182 last year and flying it I said to my wife "I am just gonna search around for the next few years and see if there is a abandoned rv-7 kit somewhere so maybe our kids and I can build something together someday". She was supportive until I immediately found an rv-7a kit online and said I had to do a 25 hour drive to go pick it up before someone else buys it. I convinced her it was something we needed for the family and I promised I wouldn't neglect everything in our lives to build this one. I got a completely un opened 2006 rv-7a kit including the finish kit for $12,500 from a very nice old timer who wasn't flying anymore and was about to sell his hanger (will be investing in buying or trading nose gear parts for the 3rd wheel to be in the right spot!).

Now building this one we are taking our sweet *** time on it and get about 30 minutes to an hour a week, at most, building! (most likely will be a 9-12year build). Most days when we have build time I get my 4 year old boy out in the shop and before I even turn the lights on we are headed off to bother the chickens, play in the mud pit in the garden, or throw rocks into the river instead :-). My life sure has changed! The only thing constant is everyone always knows I'll have a rv-7 project going!

Tips for people
- these planes are fun to build but can get addictive.
- make sure you know your personality before you start
- if you want to give up, sell your kit super cheap to someone on this site
- every time you cook - make extra so you can eat the leftovers while building
- if you want to save money get good on the World Wide Web
- sleep is sometimes more important than 4 hours of deburring
- Know what kind of plane you want and can afford before you start
- don't sell your rv-7 too early if you have kids (you probably won't need a 4 seater until both kids are at least 4 years old)
- take breaks to go to the bathroom, eat food, study for a test, or sleep at least once a day.
- when you promise something to yourself, or your wife, make sure you stick to it by setting a timer so you aren't late or buying her a present from Wyoming so when you arrive home after 50 hours of driving in 3 days and can't watch the kids till after a nap she will thank you instead of being pissed.


Still amazed by this airplane! ...DougCronkhite

Quick little story about my 8..

I hadn't flown it in 7 months, between being deployed to Afghanistan, and needing to get the ADS-B stuff done when I got home.. Anyway.. EchoUAT + SkyFX EXT installed, Engine Boroscoped (no rust anywhere.. very happy), and I changed out the tailwheel springs/chains for a direct link. Time to fly!

I take off.. get a LITTLE BIT of PIO from the tailwheel initially.. much less movement required.. and we're off.. I climbed up to 3500' to start the ADS-B verification stuff.. After about 20 minutes ATC tells me they're not getting altitude info from me.. I surmise it's the threshold setting, and decide to land.. KMYF clears me into the pattern immediately but I've got 2000' to lose to get to pattern altitude. Ease the nose down to about 600-700' / minute descent with a little power on to keep the cylinders warm. I'm sitting there fat dumb and happy until I realize I'm screaming into the pattern at 195mph.. LOL. Forgot how slippery this machine is!

Anyway.. I level out at 1400' and make a steep turn into the downwind to scrub the speed, and it feels like home again. Hit all the speeds with ease on the approach into a perfect wheelie a couple hundred feet past the numbers. Held the tail off until it wanted to come down and then pinned it.. straight as a string, no issues even with a crosswind. Slide the canopy open on the taxiway and feel the cool breeze and I've got the RV grin again like the 1st time I flew it!

What a wonderful thing we get to do here, this flying obsession!!!

Well birddogs posts got me motivated to install the filtered airbox before continuing on my baffle journeys and I'm glad I went that route. The FAB affected quite a bit of things on my front left baffles.

After getting the flange fit it was time to cut the 3/8" gap below the ramp.  ---> More Pics


Prop Lever...AJPope

There have been several discussions prop levers moving forward when the throttle friction is loosened. Some have had luck with the longer Hartzell control arm. I have an MT governor and received no reply when contacting them. Everyone's good buddy, Squaz, suggested a spring on the prop lever going back to the bulkhead. The angle bracket attached nicely to an existing bolt with a nutplate behind it. Works like a champ! (Turns out I didn't need to remove the top panel on the throttle quadrant.)  --->

Love my big screens ...Greenley

Saturday evening I flew from SW MI to SW TN to pick up a sister-in-law and niece to help prepare for a family wedding. It was an IFR flight and I was so thankful for the big beautiful screens. I have never made so many diversions for weather during a flight. While I do count on ATC to help with current weather conditions, even with the delays ADSB helps to much with having a picture of what is happening. With the combination I was able to stay well clear of trouble spots. The direct flight home however did have a detour almost to St Louis, added 200 nm to the trip of normally 450 nm. Would not have been able to do this with my 172. Here a few pics I snapped during the flight.  --->


Finishing Kit, Canopy Part 1A ...PilotjohnS 9A

So I have been working on the fitting the canopy frame, the first step on the canopy tasks. I had taken a month off to do yard work and whatever else I could find to avoid the canopy stuff. Finally I decided it needed to get done while the weather was warm.

The canopy frame was fairly close to perfect from the factory. I had to tweak 6 spots in the front hoop. I have a little more to go in the back hoop. But the back hoop requires less force and is already really close.

I took the advice of others and will cut the canopy front tubes, and will put the canopy track on after the frame is bent. I found it was much easier to do this without the tracks being on; I just used a wood space under the front tubes to raise the canopy frame up to about the right spot.

Here is how I bent the front hoop use a 3/4" conduit bender from the precision tool isle at Lowe's:  --->


Clunking Canopy when Closing ...design4p video


I have a clunking sound when the canopy is being closed. There is no connection with the rear of the canopy and the only connection at the point of clunk is the 2 hinges.

Please view a YouTube movie of the clunk.

It would appear that the hinge connected to the bulkhead jerks at the point of clunk.

Any suggests of a remedy would be most welcome.


Compression tests-hot vs cold? ...Aviaman

I had what seems a counter intuitive result. I got compression readings that were slightly higher measured cold, than when measured hot. It wasn't a big difference, something like 72,73,73,73 hot vs. 76,77,77,77 cold. It seems when hot, the clearances and fit would be tighter, causing compressions to be higher. Any ideas?

Panel Options ...David Paule -3B


I know that it is sometimes said that "anybody" can build an RV, but really .. can I? ...Lemos

Hi all. First time poster, long time reader. Finally mustered up the courage to register and post.

So I have had a dream of building an airplane for a long time. 20+ years. But I must admit, I have nearly no mechanical skills. I can do an oil change on my car or motorcycle. I can change the air filter on them too. But that is simple stuff.

Can I really build an airplane? Nobody online can give me an answer to that of course, but is there a baseline mechanical ability that one must have to assemble an RV14 kit? Can I learn as I go? Are other builders willing to come to my workshop to help?

Folks on here make this look easy, and talk like assembling the RV14 kit is nothing but matching parts and riveting them together. It can't be that easy.

I do not want to start a project that I will not finish. I can commit to 5 hours per day 5 days per week. I have the time to do this. I marginally have the money to do it. But, is it normal for me to sit here and wonder if I can do it, skill wise? Is it normal for me to fear assembling the airplane wrong and having it be junk and need to be scrapped?

I guess what I am concerned about is my own ability. If I believe I can do it, can I? Certainly I cannot be alone.

Oh, and if anyone has an RV-14 or RV-14A they want to sell to someone unsure of their own abilities, shoot me a message. In full or San Diego Area partnership.

RV-8 Misfit Canopy ...goatflieg

When initially fitting my canopy to the frame and fuselage, it looked like I would have problems fitting the canopy to the aft end of the canopy frame. Terry Lutz and Carl Franz were helping me with the fitting; I pointed out the large gaps between the aft canopy and the frame on both sides. They advised me to get the fit correct at the front and on the hoops, get the Big Cut done and see where I was at. I also called Van's Builder Support prior to the Big Cut to discuss both the Big Cut and the large gaps. I don't remember who I spoke with, but he was an experienced RV-8 builder. His suggestion was that after the Big Cut was done, I should start clamping the canopy to the frame at the front and work toward the back, clamping as I went, and see how it well it would pull together. Today I began the process, making sure the bottom edge of the canopy would fit around the vertical tubes of the canopy frame skirt. After setting three clamps on each side, it wasn't looking good at all.  --->


Some data for efficient cross country ...Carl Froehlich

Some flight data for you guys that like such stuff.

Just ~1 hour to go for the 40 hour test period. Yesterday was the high altitude data run (up to 17.5K'). As part of this run I wanted some raw data to develop cross country cruise setting. At first blush it looks like ~14.5K' is where, for the same speed, efficiency starts to fall off.

For these typical high speed cruise settings I got 27.3MPG at 14.5K', then slowly dropping off to 26.5MPG at 17.5K'.

I'm sure I could enhance the MPG numbers at slower speeds, but shoot fire, we fly RVs!

14.5K' screen shot attached.

In the meantime, I thought that you might be interested in the maintenance manual that I've been preparing. When I come across something that seems like it's worth remembering for future maintenance, I've been jotting it down, along with photos. At first it was all in one manual but the organization got unwieldy, so I separated it into chapters. At the time, I was using the Mac software Pages. More recently I changed to the free open-source Office-like package, Libre Office, which I like a lot. Hence the ".odt" suffix.  --->gt;

A Good Piece of Text To Read

Last action before advancing the throttle should be a control check.  During the 1950's there was a gentleman who took his lady friend on a flight in a tandem aircraft. As they took off his controls were jammed and they stalled and crashed with an ensuing fire. Both occupants survived a short while before succumbing that day. The cause of the accident is the lady had worn high heels for the date. While getting into the aircraft unbeknownst to either person the very bottom of her high heel came off leaving the little nail protruding from her heel. As she sat down, the nail penetrated the flooring and pinned the control cable in one spot. That resulted in the loss of control on takeoff unfortunately. Crazy things did and can happen. I suggest the last thing you do before slipping the surly bonds is a complete control check just prior to advancing the throttle. Be safe out there!

Panel Layout Review / Comments ...oren_rokach pic/vid



Dimple Dies ...Jarrett

Hello all! Just finished my vertical stabilizer last week and I am now moving forward with both the rudder and horizontal stabilizer. Today I was looking over my vertical stabilizer and I noticed that there was a very small gap between the manufactured heads and the dimpled portion of the skin denoted by the slight shadow under the heads.

My first thought was that the manufactured head was not perfectly flush with the skin (maybe a riveting mistake), so I put the flat end of a ruler over top of the rivets and saw that the rivets were indeed flush. I then took a look at my practice project and realized that these rivets did not have this same shadow under the rivets. This is when I realized that on the practice project I used Brown dimple dies and on my V-Stab I used Cleaveland dies. I then went ahead and did a controlled test. I took a piece of scrap and dimpled two #40 holes using both dies.

Notice how with the die on the left there is the slight gap, and on the right there is none, which is what I had suspected. I have had a great experience with both companies, so I'm not trying to start any wars Is this gap normal for those that have used the Cleaveland Dies? Once the plane is painted these gaps won't be visible so it's not the end of the world, but as I am ready to dimple the rudder skins I want to know if I should change back to the other dies, or be worried at all? Thanks!

Sometimes, you just have to sit back and enjoy the hilarity...N546RV

So for several work sessions, over the past couple weeks, I've been agonizing over my pitot tube position. Inboard of the bellcrank? Just outboard? Further outboard? Out at the wingtip?

I spent literal hours clamping the mast here and there, envisioning line routing, thinking of what I'd need to fabricate to secure things, considering what it'd be like to have to remove the pitot down the road for maintenance, etc etc etc. I even went so far as to test how the hard lines heated up to get an idea of how much I might be able to trim them.

After all of this, I finally settled. It was going to go one bay out from the bellcrank, against the outboard rib. So tonight was the night to make the cut and commit. Despite my agonizing, I was comfortable with my choice and didn't second-guess myself at all. It didn't even feel that odd making a hole in the skin.

Maybe it should have felt odd, because I put the hole in the wrong *** place, one bay outboard from my intended location.

I'm not even upset about it, just thoroughly amused at the irony of it all. This location is perfectly workable, I'll just need to lengthen the wiring harness between the tube and heat controller a bit.

Maybe that's the funniest part, how completely at peace I am with it not being in my carefully-chosen location. Almost amusingly anticlimactic.

Just gotta build on...

End of an era ...rongawer

I've done so many VOR approaches into Palo Alto over the years, I took a moment to reflect on the change when I got the notice from the FAA aerochart folks saying the approach would be cancelled effective 8/13/2020.

It's always been my "quick turn in" compared to the longer route needed for the RNAV. Not really impactful in the big scheme of things, but sad to see it go. Kind of reminds me of when I removed the ADF unit from my Baron and no longer did NDB approaches.

Change may be good, but it's still change. Kind of like my old coffee cup, the VOR was a faithful servant. RIP.

My RV Weekend



Updated: June 23rd, 2020

While certain businesses have been reopening for our local access, Vans currently remains closed for any walk-ins, tours and demos. You may place an order either on the phone or online and ask for a will-call pick-up, in which case our staff will make arrangements for no-contact pick-up.

We hope, of course, to be able to reopen again soon for customers to come into the building. We appreciate your understanding and patience in the meanwhile.

Much of our Oregon headquarters staff continues to work-from-home in order to ensure we are best protecting our team. We are taking orders, performing phone support, building aircraft parts and shipping kits.

Because most of our business staff are now operating away from the office, some functions may take a little longer than usual.

The following changes and limitations continue to be in place while we work under limited in-house staffing:

  • Will call orders for kits and parts are available only on a limited, pre-arranged basis. Please order and call ahead to arrange. Details are below.
  • We cannot combine multiple orders - they will need to be shipped as ordered, so please place your orders accordingly.
  • We cannot modify orders once they've received (last-minute additions and deletions).
  • Returns will be processed on a time-available basis and may be delayed due to limited staffing.

We are doing our best to keep things running as close to "normal" as possible, and the above operational limitations help us facilitate that.

Thank you for your support and understanding. We appreciate you!

Checklist Chrysalis

Made some changes in the last 24 hours after getting feedback and suggestions.  Typos, changed the order of a couple of items, formatted section titles in reverse-highlight, relabeled 'HS Trim' to 'Elevator Trim', added 'Taxi' section. 

Progress, and slowly getting there...  Probably change some more...

With the new 'Taxi' section including the line 'Transponder Verify ALT' (the new ADS-B changes require ALT while taxiing), the 'T' in GIFTSTPC2B2C now stands for 'make sure XPNDR is in ALT'.  The whole mnemonic is now:  Gas (verify L or R), Instruments (Baro, HDG bug, Altitude level-off set), Flaps (up), Trim (for T/O), Strobes (OFF), Transponder (ALT), Pump (OFF), Canopy Canopy (both latches secure - RV6 tip up has two) Belt Belt (both belts secure) Controls (free/correct).  12 seconds to say and point.

And in the last 18 years, I've started the engine in the chocks, taken off with the pitot cover on, taken off with one of the two canopy latches unlatched, and left the oil door open (it pops up at rotation).  Using this checklist faithfully would have caught those.  I'd like to avoid doing these things again.

Nuckolls Z-12 Basic Question....Reflex

After pouring through a significant number of wiring diagrams on this site and looking though several others, I've decided that staying as close as possible to Bob Nuckolls Z-12 diagram would be best for me. Some of you have a real knack for seeing things in a diagram that I just don't. With this mind, I still have a question.

Below is the Z-12 wiring diagram from The AeroElectric Connection. I have a couple of questions:
Why is there a Hall Effect sensor AND an amp meter on the battery side of the secondary alternator?
If this is necessary, why isn't there both on the primary alternator?

See lower right side of the drawing below denoted by the red arrows.

CHT Fluctuations ...RVG8tor

So my #2 cylinder CHT will set off a shock cooling alarm right from the start through the flight. I was fairly certain it was the probe. It would climb several degrees and come right back to what I figured was normal.

I finally go around to swapping the #2 for #4 probes and went for a flight. Much to my surprise the problem did not follow the probe, issue the same on cylinder #2.

I recently had morning sickness on this cylinder and did the ream procedure, exhaust valve was definitely stuck. I had to use a brass drift to get the thing out. After the reaming, smooth as butter. I don't think these two things are related, but maybe.

My only thought is that some sort of electronic interference is causing the fluctuation. Maybe from the plug wire. It the only thing I can think of that would cause this. Today I had a couple of fluctuations with more movement that before. At a steady CHT of 377 I had a swing up to 399 which set off the high CHT alarm.

So as anyone experienced anything similar? Mags are good (Dual Pmags). Just flew today and did a LOP mag check at 8500' and it was good.

I still need to download the data.

Previously this was an intermittent problem, it would be there one flight then not the next, but lately it is there all the time.

Thanks for any help.

Tate Reeves photo

One of the reasons for the flight Monday morning was to see how well a revised checklist I've been reworking performed in practice.  I took the look/feel from the sim part time stuff I've been exposed to and made one for the RV.  It's a work in progress (below), but when I get the kinks worked out I'll run it up to Office Depot and get it laminated and store it where the glareshield and the canopy meet.  On the back will be emergency checklists, light gun signals, etc.

I'm doing this in Pages (Mac) and I'd be happy to put the file online when I finish with it if anyone would like to use it as a starting point for theirs.

And before you ask, GIFTSTPC2B2C stands for:  Gas (verify L or R), Instruments (Baro, HDG bug, Altitude level-off set), Flaps (up), Trim (for T/O), Strobes (OFF), Transponder (STD), Pump (OFF), Canopy Canopy (both latches secure - RV6 tip up has two) Belt Belt (both belts secure) Controls (free/correct).  Been using this for 18 years and it covers most of the 'killer items' nicely.  'GIFT' 'STP' gets you mostly there...

From lurker to builder? ...sloengineer

Well after much pontification and persuasion of the silent partners (aka wives), it seems my dad and I are finally preparing for an RV-14A build!! The shop site is being prepped and should be done, covid permitting, in the next couple months. As I plan, please let me ask a question to the collective.

If you could only pick one item to quick build, would you pick wings or fuselage? I figure the empennage will last us until we have to make that decision, but I'd rather be prepared.


VAF Moved Over The Weekend

The VAF data moved 700.5 statute miles over the weekend from St. Louis to the buildings pictured below, around 8 miles north of the Steven F. Udvar-Hazy Center in Virginia.  Or at least most of it did, as cloud EBS volumes are explained to me.  Still wrapping my head around cloud computing, but I'll get there I promise.

This move would not have gone as smoothly as it did without the help of RV-14A builder 'bkervaski'.  One sharp guy.  Very glad Bill and RVs found each other - we're all benefiting from that!

So for a bit it's the same VAF in a faster, more stable, new location.  You should notice the faster part now.  Updated/upgraded forums software is in the warm up circle and at the plate next.  Sooner than you might think.

RV-8 throttle travel shrinking ...Pilot8

A new throttle cable from Van's has 2 1/8" travel- over time the travel will decrease by 3/8" on my IO360-M1B RV8. The throttle cable is firesleeved from the fuel servo end to the engine mount. Aluminum fiberglass tape wraps the firesleeve, and exhaust heat shields protect the cable at the crossover spots. The cable travel doesn't get any shorter after 3/8 is lost- at 50 hours, 1/4" of travel is gone. It's been repeatable with two cables. Anybody else seen this issue? 3/8" is a lot of horsepower!


Can someone tell me how Van's does this MAP line? ...jcarney

Q: Hello, I pulled this pic from Van's 360 view of the RV-14 engine.

I want to do my manifold pressure line just like they did. It looks like the line is just hose clamped on the left to the MAP sensor but what did they do on the right where it attaches to the engine? I have an AN816 coming out right there, do they just hose clamp the line to it?

Finally, what type of hose is that? Thanks!

A: AN840-4D
1/4 ID fuel rated hose

Fitting should have a restrictor added to it if you make your own.

  The move over to the new hosting platform will most likely occur this coming Sunday morning (Texas time).  What that means is that the site will definitely be offline for a bit, and might not be accessible for a few hours.  If everything goes OK and you didn't check in on the site during the first half of Sunday (Texas time), you may not notice a thing has even changed.  It could be a perfectly seamless update to you.  Also, it could explode and go full excrement, getting switched back to the current location for a bit.

  This first hurdle, and it's a big one, is to get the current data over to a more stable, robust and scaleable location.  Two test runs have worked swell in the last two weeks and testing looks good.  I've been updating the front page in parallel to the new location daily this past week, and that flow seems to be fine.  So if all goes as planned you'll see the same VAF Monday morning.  New host.  Same look and feel.
  After this weekend's move, there are some forum upgrade paths already in the pipeline that might make a few folks shat their pantaloons.  Mobile friendly, user blogs, private and public groups, chat, PM custom folders and .........wait for it.......almost certainly........image hosting.  Clean up on isle four please!   Don't scream too loud, but it'll probably happen.
  The goal of the move this weekend is to get what we already have in a new, safer, more stable place.  Then the feature upgrades get underway.  Think good thoughts, and thanks for understanding during construction.  We're swinging big, so hang on!  Up yours, 2020!  Up yours like a fox!
  Wishing you and yours a happy, safe and RV-filled weekend.

Help... Cannot get brake lines to stop adding air to the lines. ...hughfi

Hi there,

I am just about finished my RV12is E-LSA but the brakes master cylinders keep adding air into the lines right from the first compression. Any ideas what I am doing wrong. Anyone know of an instruction guide on how to make the lines just right? I talked to Matco and they pretty much told me they should be fine if they extend fully open to allow fluid in from the top. Well, they are not and they are extending fully.

I am inclined to believe it has to do with the way I constructed the lines. Also, there appears to be different fittings to go over the lines on the top 45 degree fittings compared to the bottom 90 degree fittings.

Seems simple, and I have bled a bunch of brakes before on my RV6 with no problems, but I cannot stop these cylinders adding air to the lines.

Any advice or instruction greatly appreciated.

Did you know about hurricane relocation reimbursement? ...VAF advertiser

Did you know about hurricane relocation reimbursement?
We understand that everyone has a lot more on their plates than usual this year, so we wanted to send out a reminder about the hurricane relocation programs that most insurance companies offer. I recently read an interesting article on Accuweather.com com stating that the forcasters were thinking that 2020 was going to be an above-normal season. With everything else 2020 has brought us, maybe we should have expected this

Each company is different, but many aviation insurance policies will reimburse you to move your aircraft out of the path of a named hurricane or wind storm if possible. These companies would rather pay the reimbursement expenses (usually up to a set limit) rather than pay for a totaled aircraft. If you're wondering if your insurance company partakes in a program like this, it will be listed in your policy. You can also contact your insurance broker for more information.

If you are unable to move your aircraft and need to turn in a claim, here are numbers for the companies we insure Vans Aircraft through:  --->


Edge distance issues at firewall ...Aero_Octaveus

Has anyone else had edge distance issues on the topmost hole of the side skin F-770 where the AD3 rivet attaches to the firewall flange. I haven't drilled mine yet, but it really looks like i'm going to blow the edge distance here and I cannot for the life of me figure out how to get more distance.


A shoutout to Flyleds

Just wanted to comment about my recent experience with Paul at Flyleds.

I ordered two sets of his combo landing/taxi lights for my RV7 wings a few months ago. Shipping from down under took about a month and when the box showed up, I tore in to put these together.

I found the assembly to be straightforward, but afterward, when I bench checked them I discovered that one of the 3 LEDs on one of the boards wasn't lighting up.

I emailed Paul and asked about warranty replacement and he replied right away. He said he would send out a replacement unit right away if I was close to flying, but if it wasn't urgent he would appreciate if I could send the faulty one back and he would just replace the one bad LED.

I don't even have the fuselage kit yet, so urgency wasn't an issue. He suggested that I disassemble the unit and just send back the main board in a padded envelope to cut down on shipping costs. He also mentioned that they bench check all of them, so he was a little surprised.

When I took the lenses off, I could barely see a a scratch across the face of the faulty one. Theres a good chance I did this to myself when I was assembling the lenses on top of the board. There is a note in the instructions that says you may have a little of the heat sink glue ooze up through the mounting holes when you glue them on the back and screw everything together, and that you can pick this out as long as your careful to not damage the led. I can't honestly say whether I picked the glue out of this particular LED or scratched it, but it's at least a possibility, and he said they bench check them all before sending them out...

I emailed him back and confessed that I thought this was what happened and that I'd be happy to cover shipping and whatever he thought was fair for a repair. His immediate response was don't worry about it, just cover shipping to get it to him and he would take care of it.

I shipped the board back on 4-3-2020 and thanks to the chaos Covid-19 subsequently caused with air travel, it took a while for him to get it but on 5-19-2020 I got an email from him that basically said "got it yesterday, repaired it today, will ship it out tomorrow."

It showed up at my house a couple of weeks later, repaired, with a new tube of glue to put the heat sinks back on, and some lens inserts to help center the lenses when I snapped them back in place. He didn't want any payment for the repair, or even shipping it back to me.

Long story, but it seems like we will go into all sorts of detail when we're complaining about being taken advantage of. I felt like it was important to throw out the same level of detail for a vendor who really went above and beyond to back up their product and really give customer service thats second to none.

ps- these things are super bright, and have a tiny current draw compared to incandescent. They are also reasonably priced. Same with the Flyled wingtip strobe/nav lights. I'm not flying yet, but have every reason to think that they'll fit my mission perfectly at a reasonable price. I'd happily buy this whole setup again.

RV7 N430WB First Flight! ...wjb

After 8.5 years of slow building, 2311 hours in the builders log, RV7 N430WB finally broke the surly bonds today for a successful first flight from KHAF Half Moon Bay, CA. Engine ran well; CHT's a little hot prior to break in but totally manageable. The pitot ASI died on takeoff, but I was able to fly with the GPS GS reading on Garmin. Slightly heavy right wing, but very easy to trim out.

Overall, it was a non-event! I went up with Brian Branscomb under AC 90-116, a hangar neighbor, ATP, CFI, A&P and lifelong home builder with ~10 first flights in his logbook to help keep eyes on things; he said he was a little bored -- a perfect low drama flight.

I even managed a totally respectable 3 point landing; of course it was early morning at the field and there was no one to see it.

Post flight de-cowling showed no leaks or any other issues.

Finally happy to be flying!  --->Many Pictures

Nineteen days since the last RV flight, but N617AR went flying on 6/17...and then I called 'AR' to wish her a happy birthday.

Broken bathtub, broken a/c in Tate's car, error codes in my car, squirrels in attic, ISP move planning/testing and more perfect storm items keeping me on the surface waaaaay too long, but Wednesday I finally went out and RVated!!!!  $2.60 gas over at Bridgeport and washed the plane when back.  The field shown below had just been cut, and looked really nice in the morning light.  Full size iPhone pic here.

My RV Weekend ...mr.sun

We flew the -7 back from SoCal To the Seattle area on Sunday. Had the opportunity to fly the grandson around a bit while down there. We departed vfr about 9:30 am, fueled in Red Bluff. Filed IFR and headed north. Had some IMC in layers along the way. Nearing home, runway was closed due to somebody's gear up landing. Nobody hurt. Diverted to a friend's AirPark runway and visited from opposite ends of their picnic table. Got word all was clear so flew to our home airport, put her away in the hangar and went out to dinner.

No long commutes to big airports, no long lines, security hassles, cramped metal tubes full of germs or parking hassles.

These are amazing time machines. Especially these days.......

JD Air RV14 latch ...VAF Advertiser

For all of you RV14 builders with intentions of using the Classic Aero interior, the new JD Air canopy latch is ready for immediate shipping. I have them in both Red anodized and natural aluminum.

Luke has assured RV 14 builders that the new panels are in the works and should be available soon. Specifically, you'll have to check with Luke on availability.

There is no difference mechanically between the existing latch and the new latch. The new latch only addresses additional clearance needed for the Classic Interior.

Fuel flow problem

Looking for some help diagnosing a fuel flow problem. I have a MGL Stratomaster Infinity FF-1 fuel computer with a Floscan 201 sender. It has always worked great, but all of the sudden the FF reads 1.1 gal/hr regardless of throttle/RPM. It reads 0 gal/hr with the engine off as it should. I have checked the settings, K-factor and electrical wires and all appears fine. Before I drop $400 on another Floscan that might not be the problem, I am wondering if anyone has any ideas to try. I have read that an air bubble in the sender will cause errors, but the Floscan is supposed to vent those. I did replace the fuel lines recently, but it was working fine after that. Any help would be appreciated.

An Update on AndyWAUS's "Overwhelmed After A Month of Building"

Thank you everyone again for the incredible outpour of support! Your advice is very much appreciated. I will definitely make that trip to Eugene one day when this lockdown is over. I came in person to Aurora to pick up my empennage, but couldn't get a factory tour or a demo flight because of corona, so I don't actually know how the plane flies. I only ever flew C152 and C172 (and a Yak-52 once).

So I concluded that even if I did mess up the parts with my deep countersinking, I'll just keep going and treat it as a practice project. When I see what a bad result look like, I'll reorder all VS parts and corresponding rivets and start over.

Yesterday I was busy priming for my first time. The result of course looks like ****. I did the advised here 1:2 P60G2:R7K44 ratio instead of Sherwin's recommended 1:1.5. But I had skipped over the advice to apply it lightly. So I have some spots that are very dark from the excess of paint running on the uneven surface collecting in low points and then drying up, while other spots have light tint. Only after I was done priming I went to my computer and read a thread about the SW P60G2 primer, which said spray just enough you can barely tell the difference from unprimed. Another day, another lesson, I guess. Also I learned that an N95 respirator is useless, and inhaling atomized primer is no fun. I tried buying something more advanced, but you can't just buy a respirator these days.

I finally got to riveting today. This is what I thought building a plane would be - riveting pre-manufactured parts - not all the prep that comes before it. I only set 20 or so rivets in countersunk holes with a squeezer, took me a while, but I love seeing how clean they look. I guess rivets in dimpled skin set with a gun and a bucking bar won't look nearly as neat. We'll see.

I get enough enjoyment out of it to keep coming to the garage. I'm not even dreaming about flying it when I'm so early in the build. It's just so many new little things that I try doing for the first time in my life, and the resulting quality less than desired. All your words of support helped tremendously! Even Dan's advice to quit now (I ain't quitting until I'm done ruining the parts that I paid 4 grand for). Good to know I don't need to worry about mods now and will have plenty of time to decide.

Also I was stressing about a bunch of scratch marks on the pieces that I left while pushing the countersink cage, drilling, and fitting parts together. But then I took that maroon pad to prepare parts for priming and soon realized how stupid it was to worry about scratches.

Milestone: First Meeting w/my Tech Counselor Today ...msmst25 RV-10

I met my EAA tech counselor, Jim Frisbee, today. That has to be the greatest benefit of EAA membership. It was extremely informative, and now I feel (mostly) comfortable enough to move on with the rudder assembly. I used the double sided tape on the trailing edge wedge and have it all clamped together. Planning to do the double blind rivets tomorrow. I practiced on the trailing edge of the practice kit, and the results with the pneumatic squeezer and the trailing edge set from Cleaveland tool seemed very good. If you wonder why there aren't clekos in every hole, it's because the holes drilled in the angle aluminum didn't line up well enough and I didn't want to force it and risk damage to the rudder skins.

Keeping my seats cool in the summer sun ...seagull

If you live in a hot climate like me or leave your plane in the sun you have experienced putting on seat belts with extremely hot buckles. I found a solution using a spring type windshield sun screen. This type coils up when not being used, it's light weight and fits behind the seat. It covers both seats from the panel to behind the seats. Cost on Amazon was (2) for $15.99.

Feeling overwhelmed after a month of building

Hello fellow builders. I'm a new builder, just registered, and this is my first post here.

I was very excited to buy an empennage kit for RV-10 and all the tools. I watched hours of youtube videos and read the Van's builder's manual twice.

Quite frankly, I expected more of an IKEA experience with finished parts and exact assembly instructions. What I found was more of an art project where it's up to me to decide when edges are deburred smooth enough or holes countersunk deep enough. I just can't seem to get the hang of it - using countersinking as an example - the manual says countersink 7 microstop clicks deeper than flush for the piece to accept dimpled skin. But then it says the dimpled piece should sit flat on top of the countersunk piece. If I do 7 clicks and test with a dimpled piece, it doesn't sit anywhere near flat. If I countersink deeper it does sit flat, but how deep can I go before compromising the structural integrity? I have a vertical stabilizer rear spar sitting on the workbench with a bunch of holes all countersunk to different depth, and I'm not sure what to do.

That was just an example. Another thing I just found a few days ago is the idea of "mods". I want to build the best airplane for myself that I would love flying. Now I'm thinking if I don't make proper decisions early in the building process I would regret not having something (like a rudder servo trim).

Did you feel this way when you were just starting?


Proseal fillet question ...Jskyking

This is my first pro seal job and I'm trying to visualize the "generous fillet of sealant approx 3/8" radius at the interior corner of the rib".......

1. Are they saying the Proseal radius should be 3/8" tall?


The radius should extend 3/8" from the flange. In other words to a build up vertically or laterally.

2. What are they calling the "interior corner". I would think that would be the corners where the rear baffle mates up to each rib.
I suppose one could interpret the paragraph as to do each corner of only the most inboard rib and the most outboard rib.

It's a head scratcher, I appreciate an interpretation.

Since the first inner flange was unsatisfactory, I made another one. Here it is, still in the canopy as laminated. I've removed the peel ply but haven't separated it yet. I hope it's not too thin....


After a long hiatus, back with a question about the aileron inboard bracket ...Scott Emerson RV-14A

On the Aileron inboard bracket safety bulletin, unlike the initial instructions that are replaced by the bulletin, the bulletin instructions did not specifically mention to remove the same "hatch area" as the initial instructions and so I forgot to do that on the right wing when I installed it.

I am in the process of building the left wing and am wondering if it is indeed still supposed to be removed since the bulletin that I have did not mention to do so. When I looked at the installed bracket, the tab on 1013E-L flushly meets the aileron spar face. It essentially acts as a hard stop. The deflection of the aileron seems to be within range of movement in the upward travel.

I am not sure if I should remove the right aileron and remove the tab on the installed bracket and then make the left to match, or leave the tab on both.

Looking at the SB in figure 13, it shows the parts both with the tab not cut off and there are no instructions to do so, but if you look at figure 14, the drawing no longer shows the "tab".

Its been over a year and a half since I last did metal work on this project and trying to get back into the swing of things!


Getting a correct Big Cut trim line ...Draker

Well, the weather in NorCal this weekend isn't going to get very hot, so I'm going to put off the big cut. This gives me another week to agonize over the cut line on my (tipper) canopy. I can't seem to get the top of the canopy less than an inch or so from the roll bar. I've trimmed and trimmed and trimmed (probably trimmed too much) and it still doesn't rest close to the roll bar. Van's says to draw the line "when you have gotten the fit to be somewhat close". Does 1 inch count as somewhat?

  Lots of good Wx and I'm guessing RVating.  I spent the weekend doing yardwork and fighting a lion-hearted campaign against our tub, replacing came-with-the-house circa 1987 faucet cartridges to finally stop the dripping.  Epic battle.  Much cursing.  Some crying.  A little blood.  I won.
  Hope you had a nice weekend and got to spend some quality time with your RV and/or RV project!

N418RT Gets a new home in SoCal ...GimpyPilot

Hi Folks...

I didn't build it, but I was very graciously allowed to acquire RV-7A N418RT from her builder, (Richie at KOMN), who completed it in 2016 and flew her for 200 hours. I had the distinct pleasure of taking her home to KVNY last week in 16.5 flight hours. There's not a squawk to be found, and very little I will do to make he my own. (I've just ordered the parts for my hand brakes, and I'll have a GMA-345 in the panel to go with the existing G3x/GTN 650 shortly. Beyond that, she's perfect for me already.)

Thanks so much Richie! You are a wonderful person, and I couldn't have asked for a nicer airplane.


Status Report ...vinzer RV-10

Its being a while since I have not posted here. Sorry. Was busy with everything + COVID thing. I know, no excuses when building RV-10, reports should be posted periodically
So here is my report:

Vertical stab completed 100%
Rudder completed 90% (waiting for inspection before closing)
Horizontal stab completed 90% (waiting for inspection before closing)
Elevators completed 80% (waiting for inspection before closing + planning to rebuild trailing edges)
Tailcone completed 40% (working on it right now, hope to finish it soon)

My wings kit is on its way, few days ago got confirmation from VANs about crating process and completed my payment. So will soon start to work on my wings

So far everything goes smooth, my wife and kids help me alot with this build.
I am updating my youtube channel with new videos about my build as well as my blog page. Both can be found in my signature.

On another note I am just curious if someone is currently selling or planning to sell fuselage and finishing kit. I know sometimes people give up on building or changing their minds. Anyway just curious as I would probably want to buy these kits if some one is selling. I will post in classifieds WTB.

Tailwheel shifts to "castering" mode too easily ...Leopold

Q: Hi, all.

I've got an RV8 with (I think) a Bell tailwheel. Lately, when taxiing, and turning right (right rudder), the tailwheel shifts from steerable to castering with only minimal pressure. Going left, it does not have that problem.

I took the tailwheel assembly apart yesterday, cleaned all the parts (including the spring and the dog that it fits into, and the rectangular hole in the bolt that the dog fits into) with solvent, re-greased, and put it back together. Same problem.

Took it apart, cleaned it, and looked at it (should've done that first time). There is some metal wear; the rectangular hole really is not exactly rectangular, and the place where the dog "breaks" from steering to castering also looks slightly worn.

I was thinking of just replacing all those parts...does anyone think there is an easier solution that I am missing?

Surface corrosion on tappet ...N360DF


My engine parts was stored in oily paper to avoid corrosion.
But unfortunately the paper was bleached and properly had a chlorine content. The loss is big and parts need to be bought again.

The tappets is pretty good, but some have some surface pitting.
Very shallow. I am not afraid they breaks down, they will not.
But I have not knowledge how the tappets works ?

Maybe someone may help me?

Do they seal or is the oil film leaking between case and tappet?
Could some pitting reduce pressure some way?
I was told they actually rotate to spread the wear ?
Anyone who know more in detail ?

Look at picture! This is the worst one! The rust easy goes off and
I just slightly used 1200 wet paper. I will check OD with micrometer.
And polish to get smooth surface.

The tappet surface against cam is perfect.

Thanks for all help!

Things happen for a good reason ...Sobnorslu

Last week , on take off , right around 60 knots I felt a slight vibration , I did an RTO and as soon as I exited the runway , the plane felt like it was taxiing on mud , it was after 6 pm , made a few phone calls , no answer , my mechanic said he left and was close to his house , the field is uncontrolled , there was a 172 doing touch and goes , he radioed a phone number which I called right way , within 10 minutes two guys showed up , ED's aircraft refinishing and his buddy Jay , they tried to inflate it but the tube was bad , they went back to their hangar and got me a spare nose wheel , I taxied it back and as soon as I parked , I saw this massive patch of Fog rolling in ( unforcasted ) I kid you not , within 15 minutes the field was IFR , 200 ft ceiling , mist and 1/4 mile visibility , im glad I didn't fly that day , I am instrument rated but the airplane is not ! I was planning on doing a night flight with a landing/taxiback at JFK . Things happen for a good reason , I stayed at the airport until 20:30 , kept listening to the ATIS as the weather was worsening .  --->


For The Historical Record

I realized that I never really finished this thread.

So after both tanks passing the initial leak test I removed the cork gaskets and installed the plates with just pro seal.

After letting the tanks cure for at least two weeks, I retested using the same procedure. Both tanks passed the leak tests.

Procedure used for testing tanks:
Closed or sealed up all tank openings
Installed a 0 to 15 inches of water pressure gauge on the tank drain fitting.
Set up a temp probe next to the tank.
Pressured up tank to 9 inches of water.
Recorded the pressure and temperature every 30 minutes to an hour for over 12 hours.
Used leak test fluid periodically to look for leaks. (SNOOP or equivalent)
Let sit overnight, continued recording temp and pressure for another 12 hrs.
Ended test

The pressure / temp recording allowed me to track the pressure movements (and they will move) during the 24 hr test. The method for making sense of the pressure fluctuations is:

Pressure fall and temp falls = normal contraction of air volume.
Pressure rises and temp rises = normal expansion of air volume.
Pressure falls and temp stays the same or rises = possible leak
Pressure stays the same and temps rise = possible leak
Pressure increases and the temp falls = laws of physics ceased working

Zuldarin's 507 on Glareshield ....beat me to it!

Hi everybody, at the risk of hijacking DR's thread I thought I would give a status update on my attempts at designing a similar glare-shield mount. Using Solidworks I designed something akin to what DR posted but with a couple of changes to fit my own needs. I then sent that design to Geoff at Aerosport to print on his industrial 3D printer. The result came back looking really nice as you can see in the pictures below. I know Geoff has some great idea's for modifications for future models but this is where we are for now.

One aspect specific to the RV-10 is that I used the Aerosport 310 carbon fiber panel which means my AP controller had to be adjusted to fit. Additionally, I didn't want the connector to be attached without the back-shell. I moved the mount higher up on the glare-shield so that the full connector could be used.

I'm compiling study notes once again (this time for the ATP written), and continuing on with a process that worked for me while prepping for the instrument, commercial and multi ratings.  The end goal (other than passing) is to have a several hundred page document in PDF format on my phone in my pocket so I can study during life wait times (treadmill, waiting for takeout, etc). 

Beats reading the news and I'm doing something productive...

1. I purchased a 1-year rental of popular study software that runs on my iPad and open the app.  Many to choose from.
2. I plugged the iPad into my Mac, started QuickTime Player (comes with the Mac)
3. Started a new 'recording' with the iPad as the camera input source.  This gives me a copy of what is on my iPad displayed in a window on my Mac.
4. I opened Pages on the Mac.
5. I use Command-Control-Shift-4 to copy to the clipboard a question/explanation off the iPad and paste (Command-V) it into Pages.
6. Use the same keystrokes to grab copies of the relevant figures for that question.
7. Add a 'shape' to the figures (the little fountain pen icon in the upper right corner) if needed.  Make it red, put a little arrow on the end if you feel like it.
8. Put in a page break and move on the next question.
9. Do five of these a day and before you know it you'll have some crazy good study notes - you actually learn the material.
10. When I'm done I'll have a several hundred page PDF with all of the questions answered, explained, and with annotated figures.

On my phone....in my pocket.  No fumbling through books.

A sample page from today's study session:


And yes, I create PDF lists to study.  I turned a baseball-sized pile of flash cards into a 2 1/2 page PDF doc of Phenom 300 Limitations for the part time sim side job.   Lives in my phone now.  A grab....

The roughly 3x5 card below (my Mona Lisa) shows (8) flight profiles for the Phenom, and it reads (to me) like a METAR.  For the yoke in the sim.  I'll translate the first column (Precision Approach):  Holding 170 knots, Approach checklist, 15nm or outbound Flaps 1 bug 150, Glideslope Alive Gear down, Flaps 2, Bug 130, Glideslope 1 dot Landing flaps, Vref, Outer marker/Established Glideslope set go around altitude, before landing checklist (below that the Missed Approach).

And yeah I'll probably end up typing some card like this for the RV...  I'm weird, I know.  Emergency scenarios and such...



I need to replace this sheave that lifts my hangar door via a hydraulic ram. There are 4 cables that go around the sheave, and the door is a one-piece, metal frame with corrugated steel (read heavy). I can use 6061T6 for the replacement. Opinions on the strength of that alloy? The sheave is 4" diameter with a 1" steel pin and bronze bushings. The broken pin seized in the bushings and was spinning until it (probably after a few years) wore down to 1/4" diameter then failed.  --->


Fuel tank baffle line of leaky rivets -- Advice?

After feeling really good about building one fuel tank that had no leaks upon pressure testing, I confidently undertook to seal and rivet the second one. as a new fuel tank expert, I knew exactly what to do, and it all went swimmingly well.

Until the pressure test.

Fortunately, everything is very well sealed, except for about 15 rivets on the top inboard edge of the baffle (the suds below are just from running down the tank skin). I am at a loss to understand what happened here, but I assume that it was an inadequate bead of sealant on this edge. I don't get why, though, because sealant squeezed out the rear side of this joint when it was assembled. There is a nice bead along the back side, but clearly, air is leaking in the front (internal) side and reaching the rivets.

I can see a few options for repairing, but would like some advice, if you'd be so kind...

1. Drill out these rivets, and reinstall with sealant on the heads (I didn't apply sealant to these rivets originally, assuming the bead inside the tank would be adequate). This would be super easy, but have the greatest likelihood of not working, or failing later in the life of the tank.

2. Drill out these rivets, pry the skin back and clean the faying surfaces of any sealant remaining, squirt some sealant into the gap, cleco it, shoot a few rivets for structural integrity and then try a new low pressure test to see if it worked, then drive the rest of the rivets. This seems like it would work, but there's a chance shooting new sealant wouldn't cover the whole gap. Also, a chance that I could just end up damaging the sealant bead inboard and outboard of the repair. The cleaning part would be really difficult.

3. Drill out the rivets on the entire top of the baffle and try to apply a new bead after cleaning.

4. Pull the level sensor and try to apply sealant from the inside through that hole.

5. Cut a hole in the baffle, reseal from inside, and apply a repair plate.

What would you do? What has the best chance of working?

Help ID parts..... RV-10

I got my RV-10 QB wings/fuselage and empennage kit this week. Inventory done, all good, except there was one little bundle of parts that I can't reconcile against the inventory (I may just be missing them but it's 19 pages of single spaced fun).

Any help in ID'ing these parts (just tell me where they go in the airplane, I'll figure it out from there) would be appreciated. The little aluminum strip I'm not worried about - I'm sure I'll figure that one out when I get to that page in the plans


FlyLeds Wig Wag Module

Hello All

Today I installed my Flyleds Wig Wags module that I bought last summer in Oshkosh ( Yep I know I'm slow ) and when I tested them they worked on all 8 flashing modes but that is it...They don't go back to steady lights even though I turned them off for more than a seconds as called for then back ON...

They are always flashing

Anyone here ever had this happening with their Flyleds Wig Wag module or know something I may have missed??



A: (Paul at Flyleds)
Hi Bruno

The Single Switch mode is optional.
To enable this mode of operation, press and hold the PATTERN button and then apply power.
Release the PATTERN button. The lights will flash briefly and then come on continuously.
This procedure only needs to be performed once at installation.

From there:
- Turn your panel switch ON, and both lights come on in Landing Light mode as normal.
- To activate WigWag mode, turn the switch OFF then back ON again within one second.
- To go back to Landing Lights, turn the switch OFF then back ON again after one second.

To return the module to WigWag Only mode, repeat the procedure given above. The lights will briefly flash left/right, and then begin to flash the stored wigwag pattern.


Flutter of AST in Flight ...David Rohrlick RV-12iS

I have been documenting my test flights extensively using a 360 camera mounted on the tail tie down. I have noticed that the the AST tends to flutter in flight. This it not notable whatsoever in the stick in flight. I have the older style AST trim with no bend in the rod. There is a very small amount of play when you hold the stabilator stationary on the ground and then flex the AST. I have looked at three other RV-12's and they seam to have to same amount of static play. I made a 1 min video so you can all see what I'm talking about. Anyone have any insight on this?  --->

First Flight... the pilot. Where did you solo. ...gasman

My training and solo was out of this strip in 1979. By then it had been paved but only out to a width of 25 feet... and even at that the edges were eroded back to 20 feet by the time I started training there. There was a farm fence on one end and a road with power lines at the other. The runway was 1800' long and the turnoff was 3/4 down the runway. We were trained to make that turnoff, it led straight to the gas station type fuel pump.

You think all of this is normal.... until at around 10 hours we head out of our training area and go here.  This field is 7000' long by 150' wide. For me then, it was hard to land on. Go figure. The instructors at that airport would not let their students land in Petaluma.

My little strip was "normal" to us students and all that were based there. And that included a guy with a P-51. This guy always made the first turnoff. Remember the road at the end of the runway.... Driving in for a lesson one day, I looked down the runway just in time to see the P-51 lift off!! With the sun hitting the face of the prop, it looked (the disc) as wide as the runway.

Learn to fly from a small strip and you will never regret it.


Private Airstrip Zoning ...crabandy

It's really no surprise I'm looking to the VAF community for help with this, throughout my build and beyond the people ad advice have really made things happen for me.

I rushed my "special use zoning permit" to the county just before they shut their doors due to the Covid several months ago. Depending on weather/farmer/contractor I would like to break ground next fall through next summer.

We purchased our property to build a house, airstrip and hangar on. Now we just need to make it happen. I've planned out the runway with a dirt contractor who used to be on the county planning commission and was also approved by the airport coffee drinkers association. I'm attempting to do this right for the long term, I want this runway to be there for a LONG time and need the paperwork to be in order.

It's now happening fast, the letters to the neighbors already went out and the commission meeting is next week. We've already delivered my wife's famous homemade cinnamon rolls and visited with all those affected by the zoning change except 2 which are out of town. I think this portion on the zoning application is a "go."

I'm not a lawyer but the initial planning commission findings are very favorable:  --->

What's Causing This Weird Vibration?

Since my OP last April,  I've additional info. Ideas, anyone?

The weirdness: a vibration suddenly kicks in at an IAS between 90 and 110 mph during the [i]first [i] of the day's take-offs. Nothing subsequent.

The Whirl Wind 74RV spinner has broken - thrown out a chunk - twice within 700 hours, and the third is showing damage. The spinner bulkhead is chafed on on only one side, and after a few hours the screws can again be snugged down because enough material has eroded away from spinner and bulkhead.

What on earth would cause an engine to break spinners!

I've heard of vernatherm, governor, pressure spring, sticky valve guide notions that seem to address the obvious link between oil and under cowl temperatures with the vibration; some sort of resonance interior to the engine that excites the prop/spinner combo. But, my goodness, all seem like a stretch. My gut still says engine vibration isolators are not doing their job (They are the Lord mounts with the secondary internal cone limiting start-up motion.)

A 200RV prop Whirl Wind loaned to me hasn't altered the vibration phenomenon. Curiously, Whirl Wind has stepped away from stroker 360s (and anything else with greater than 9.6:1). From their website: "(I)0-370/375 NOT SUPPORTED"

So much would seem to implicate the airframe, but I've dismissed that mainly over the temperature issue - first takeoff only, and sometimes not at all if temps are already elevated - and magnitude is linked to power.

Any further ideas, brain trust?

RV Bits Plenum Fit ...SeanB

Hi. I'm getting close to the paper clip trick with trimming my RV7 baffles, so getting close. I plan to install my RV Bits carbon plenum, so I put it on the plane for a look. Love the carbon! But...the fit fore and aft is not good. Probably half an inch off. Also, there is the piece that steps out by the oil cooler brace. Not even close to fitting. Finally, where the vertical baffles bend at cylinders one and two, the carbon plenum does not match with its contour. Anyone have experience installing one of these plenums on a 7 or 9? Pics? Thank you very much!

I had the same issues to start......
I wrestled with this for a good amount of time. I even had multiple e-mails with Jan in South Africa. What "did the trick" for me was to remove "both" the forward and aft baffle braces, then it started to seat in much better. Any small gaps will be filled with the weather stripping you choose to make the seal. And also when you actual screw it in tight. The next, and much bigger issue will be the cowl inlet to plenum seal. I designed a strip much like what Vans normally uses in the area but, that comes up much higher and wraps up and around in between the cowl and the ramps. You install them "after" the lower cowl is attached. I also used the oversized oil cooler. I'll get a few pix posted here later. All worked great in the end! Engine temps are good and no issues so far........

Are you using the "stock" Vans cowling?

Tim, thanks for your reply. I also elected not to install those two brackets. Seems the plenum will provide more than enough support. I'll need to investigate futher, but I believe the plenum flanges may be at a slightly different angle compared to the face of the baffles. This could be causing the plenum to "push" away. I also don't know if I am supposed to cut off the little extension for cylinder number four area of the oil cooler brace. Yes, using Van's pink cowling.

I too am installing a remote cooler, just behind #3. It's the Showplanes setup with large cooler and shutter. Using an IO-375 with squirters, so need the help.

The outboard baffles get a vertical bend on #1 and #2 to taper the form for the intake area. The plenum doesn't match well here either.

Appreciate seeing your pics and ideas. Thanks!

Cornucopia Getaway ...petehowell -9A

About mid-week, Andi and I decided we were going to get out of town and head up north to camp, so I searched for destinations. Bowstring is nice, but we were just over there for lunch. Browsing the RAF site, I saw there was a little strip up on Lake Superior that looked like fun - Cornucopia. 2000 ft, bikes in the shed, camping allowed, our kinda place, so I sent an email to the airport manager, and we connected on the phone. Gave me the brief - stay in the middle - and avoid the last 100 feet of the SW end - it drops off. He said camping was allowed, but that the ticks were really thick at the airport right now - maybe find a room in town. He had some suggestions - they all know each other in "Corny".  --->

New Project ...Lufthans


I am picking up this new to me -3 next weekend.

She's flying, but it's really a 50-foot aircraft. So after playing around with it for a couple of days, I plan to take her apart and bring her to my workshop (which unfortunately is not on an airport)

The plan:
* Polish all the corrosion out
* Fix crooked tailwheel
* Make new righthand elevator (some gorilla has tried to use molten lead or something on a dent, only to make things worse. And more flutter-prone)
* Smoothen all fiberglass wing/tailplane tips
* Try to get some dents out of the turtledeck (very carefully)
* Do a complete rewiring job
* Do a new panel
* Do a new canopy skirt
* Do a new windscreen frame
* Make the engine cowling presentable
* Pull all of the aluminum tape off the fiberglass and paint it
* Put 8.5:1 pistons in engine
* Do an EFI conversion on the engine
* Catto prop
* New spinner
* New lightweight starter
* Ditch the generator in favour of an alternator

On the plus side: she's light! 750 lbs with an O-320. And it's a -3B with new(ish) quick-built wing.

Can't wait to get started!!!

Houston area monthly lunch (June 2020) (WE'RE BAAACK)

That's right, it's time to get this going again. I'm putting the notice out a bit early for this one since it's different from the norm. As alluded to previously, this month I'm going to host at my hangar at Sport Flyers (27XS). Assembly time will be the usual 11:30, a week from this Saturday (June 20th).

I'll have a pile of ribs and assorted sides, plus coolers full of drinks. I'll try and rustle up some tables and chairs, but seating may be at a premium. I'd suggest you try and bring your own chairs if possible.

Here's the one request I have for everyone: Please let me know if you're planning on attending, and if you intend to fly in. The former is so I can plan for food stockpiling, the latter is so I can figure out how many neighbors I need to talk to to secure aircraft parking. I can fit four, maybe five RV-size aircraft on my lot, more than that and we'll have to get creative.

Just reply here, send a private message/email through the forums, or text me at four2three 4three2 nine4three7.

Street address is 4614 Windsock Ln, Brookshire. For fly-ins, it'll be the seventh hangar from the north, on the west side of the field.

NOTE FOR FLY-INS: Please don't park on the grass without someone on the ground guiding you. There are culverts on either side of my ramp that you do not want to put a wheel into. I'll have them flagged, but I'd still prefer to provide guidance. Better safe than sorry.


Wing Root Mounted Filter Setup for RV-14/14A ...Aircraft Specialty (VAF advertiser)

After the recent release of the RV14 SDS duplex cabin and wing root fuel line kit, we received a lot of feedback from builders who were interested in a wing root filter setup for the standard cabin fuel line setup.

We are now announcing the release of a Wing Root Mounted filter setup for the RV14/14A cabin.

This setup removes the filter in the center tunnel and adds a high quality serviceable filter in each of the wing roots with a shutoff valve for servicing during the conditional inspections. This kit is available as a complete kit which includes all the Cabin Components as well as the Wing Root components. Or it is available as an add on kit for those who are utilizing our Rv14 Cabin Fuel Kit, or for those who already completed their own cabin fuel lines.  --->

FIRST FLIGHT ...Lizard Lips

RV-14A, N468JG, matured into a real lady today by making her first flight ever into the earth's atmosphere. She flew "hands-off" from the very beginning and the Lycoming IO-390 purred like a kitten. She is now a "Real Airplane" ready to join the ranks of the thousands of RV's that have preceeded her.

The flight took place at Gladewater Municipal Airport, 07F, this morning at approximately 9:30 AM CDT after two-years, two weeks in construction.

2020 Falcon Flight Formation Clinic was a SUCCESS! ...Sid

The 2020 Falcon Flight Formation Clinic took place May 29-31 at KTPL Draughon-Miller Central Texas Regional in Temple, Texas. It was an unparalleled success. After having slipped the event from April due to the nationwide lockdown, and worries over possible bad weather, we were treated to the best possible late-spring weather; an outstanding airport staff and EXPANSIVE large hangar, ramp, and briefing facilities; and nearly three dozen pilots and RVs raring to formate.

Ron "Shorts" Walker and Bobby "Luke" Lucroy led the event, surrounded by Falcon Flight premiering our new all-blue uniforms. I think it's best to lay out the event through numbers:

34 RVs and pilots, some from as far away as Wisconsin, west Colorado, and even Tucson. And Arkansas.

6 check rides
- 3 Wingmen check rides
- 3 Flight Lead check rides
Luke and Shorts earned their Large Formation Certifications
1 Red Scary earned his 2-ship solo
1 2-Ship wingman earned his 4-ship solo
4 new Red Scaries (welcome aboard!)

Today's engine puzzler #2

I was inspired by David Harris's recent puzzler -- and who doesn't love Click and Clack? Here's my engine puzzler. Probably an easy one but I'm posting because it stumped me for a while, and perhaps some other engine-challenged folks like me can get some benefit. At the risk of getting beat up like David did, I'm not going to post the answer right away. But it will be later today or tomorrow, or as soon as someone gets it. If you're frustrated by that you can subscribe to this thread and you'll get the follow-ups in your inbox.

So here's the setup: at around 1400 hours the engine began having a hard starting issue. Mostly it would start right up but maybe 1 out of 10 times it would just crank and crank. I could get it started with some starter fluid (I know, not safe, but it did the trick).

This is an RV-6 with Lycoming O-360 A1A, cabureted, P-mag right side with aircraft ignition harness, traditional magneto left side, iridium lifetime plugs all around. I had the magneto serviced, adjusted the carb, checked the fuel screens & verified no water in the fuel, cleaned & gapped the plugs. Checked all ignition wires with no problems found. No change.

Then I listened to an EAA webinar by Vic Syracuse. Bingo!

The clues are there, if you know the answer write it on a set of James Aircraft RV-6 high speed fiberglass pressure recovery wheel pants and send it to me PO box [etc.] OR post it here :-)

RV-12 Safety Directive SD-00017 published: Check fuel return line flow ...mothership

We have published Safety Directive SD-00017, which applies only to the original/legacy RV-12 (it does not apply to the RV-12iS).

This Safety Directive requires inspection before further flight of the fuel flow return line to ensure fuel is actually flowing through the return. This is a simple and quick check and can be accomplished by the owner/operator in about 5 minutes. No tools or parts are required and there is nothing you need to order to conduct the inspection.

In the event the return line is found to be blocked, the document contains the mandatory additional steps to rectify the issue.

Context: A blocked return line fitting was discovered on one RV-12 in the field. Due to the potential risk and impact of a fuel flow issue, we have issued this as a before-further-flight notice. Performing the check of this critical system is a quick and simple process.

Canopy Inner FLange
Back to the regularly unscheduled progress report.

Also, back to the canopy. In areas, the bottom edge of the canopy was too much of a sharp edge to laminate fiberglass around, so I took a two-fold approach to that. I formed a flox bead there and then after it cured, rounded it. There were places that now protruded too much to assemble the fairing on, so I reshaped those with a more gentle radius, blending it into the outer flange. Yes, I went back and smoothed those edges.

In retrospect, flox was the wrong stuff to use here. It would have been better if I'd used micro, since this was nothing more than a bit of non-structural shaping.

With that out of the way, I taped over the area and prepared the surface to lay up the inner flange. I'm using Aircraft Spruce's crowfoot cloth, p/n 120-38 for this, because it forms better. Since this cloth is only .004 thick, I'm using six plies. And because it's warmer now and I'm still in my busy season, I decided to do it in overlapping sections. Here's the first. The diagonal white stripes are the ends the short overlapping pieces of peel ply.

Usual suspects 52F the other day.  dr



I was talking with Mel Asberry of DAR fame Wednesday evening, and he told me he recently counted up all the folders in his office (he has one for every DAR inspection he has ever done).  The count?  975.

Let that sink in a bit and ponder what it represents to the aviation (especially RV) world.  The thought did occur that if he does one each week for the rest of the year he'll break 1,000.  That would be something nice to be able to report in a troubling year.

Mel (and Ann) are RV royalty, I consider both friends, and I still remember the things he found on my RV-6 back in 2002 during her look-over.

Call Mel.  He's in the Texas section of the DAR page.



Q: Passed my Airworthiness inspection Monday and plan to make the first flight of my RV-14A Saturday. Installed is a factory new Lycoming IO-390. The first few flights will consist of exploring the envelope of the airplane and getting the feel of it's flight characteristics. What power settings would you guys suggest for a new engine during the first few hours? I had thought maybe 2300 rpm/23 "Hg manifold pressure or maybe 2400/24. During this break-in period should the engine be run "hard" or should it be run at low power settings? Your opinions are appreciated.

RE: Non-Advertisers Abusing the Posting Rules.

A special request....

If an aviation-oriented business that doesn't advertise on VAF tries to solicit your business or market/support their products through the Private Message (PM), email, or other features of the VAF Forums, would you please let me know about it?  There have been some reports of abuse of the VAF posting rules lately and I'd like to get on top of that (trying my hardest to run a tight ship during very stressful times).

'Food cart in the parking lot example' described in the rules.  I'd like to keep paying my bills and feed the fam.

Thank you as always and best,

Albuquerque RVers to the rescue

Thank you to all the RVers who assisted me when my RV was down on Memorial Day at KAEG.
My cross country trip from Florida to South Lake Tahoe was interrupted when my starter failed while attempting to leave KAEG. Then, minutes later, the calvary arrived, when I see a 7 ship overhead break with smoke. After their debrief, it was all hands on deck. David Otero was especially helpful as we pulled my plane to his hanger & proceeded to remove & bench test my starter. Hoping a good clean & lube would allow me to continue, it wasn't to be.
The starter damage was under warranty by SkyTek & they have really stepped forward to get me back in the air. They have agreed to swap out my damaged starter. That's great customer service. I'l make my way back to KAEG in a few weeks to continue my trip.
Gotta love this community!

Speed Run Data ...RV7ForMe

Although Not building related but it reminded me what a capable plane I am building. Went up in the other -7A yesterday and did a 4 leg box speed run at 5000ft at full everything. I am a bit disappointed it didn't match the VANS numbers but maybe I need to do it again at 8000ft. 8500? at what alt are the vans numbers done?

RV 9 Inboard flap fairing issues ...DennisRhodes

On an RV9 or 9A there's a fairing on the bottom side adjacent to the fuselage that covers up a small cavity at the end of each side flap. This is close proximity to the linkage that operates the flap mechanism. The fairing for this area is a extended piece of fuselage skin which must move with the extension of that Fowler type flap.

After about 750 hours I began to get some vibration noise from that fairing because its only held tight against the fuselage bottom from the spring back in the metal. I suspect the airflow is causing it to vibrate against the fuselage and or flap bracket and causing the noise. Also seeing some cracks and other indications on this moveable piece of fuselage skin was wondering if others have noticed this.

If so, has anyone just completely removed this section and left the hole exposed. Or has anyone come up with a better idea to utilize the fairing or modify the fairing to get a tighter seal . Interested in your comments or ideas for a fix. --->

Installing red cube on carburated engine ...riasbeck

I've been following the various red cube threads for a couple weeks, but can't decide how/where to install my fuel flow sensor on a RV8 with a Lyclone engine.

Basically, it seems that these sensors are very susceptible to heat and vibration. In fact Vic Syracuse, in his most recent EAA webinar called out a couple of installations that had it mounted to the engine mount as a potential source of failure. So I'd planned to put it on the firewall with a heat shield between the gascolator and the engine driven fuel pump with a teflon/SS line from the cube to the engine pump, all uphill.

On the other hand, when I opened the package yesterday, the instructions from EI said that it HAS to go between the "last fuel pump" (i.e. the engine pump) and the carburator, otherwise it may lead to vapor lock and inaccurate readings.

I can live with iffy readings, but vapor lock got my attention.

How has everyone with a non-fuel injected set up done it, and how well did it work?

Status Report ...jcarne RV-7A

Oh boy, started the cowl a couple of days ago. I can already tell this is going to be fun...

After a bit of sanding and trimming this is about the best I can get the halves nested behind the spinner. The flanges of the top don't extend down far enough and I can't bring them together anymore as the spinner area would no longer be round. Looks like I have some flox jobs in store for the future.  --->


A Great Idea For Displaying Plans

I put all the files together in a giant PDF so I could take them with me on my iPad, then mounted a TV with a laptop in the garage so I could use those and make notes on them digitally instead of having to use the paper.

It's so nice to be able to CTRL+F instead of having to flip through pages.

Flywheel timer ...greghale

I've come up with a flywheel timing pointer that allowed me to set the ignition timing from the top of the engine. It clamps to the flywheel. You point one end of the pointer at the timing mark on the flywheel, clamp that position then move the prop until the other end of the pointer points to the crankcase split. I came up with this to help in timing my IO-540 with the new 6 cylinder E-Mag from the top of the engine. It can also be used for timing a standard mag. If the crank case is covered up by a baffle, you can transfer that position to the front side of the baffle for the pointer to point at.  --->


Skin Deburring Question ...RV701775

On skins and other punched parts where there are curves or bends in the punched area there are significant burrs on each side of the curve that I am finding difficult to debur without taking off quite a bit of material from areas around the curve. If I use a flat needle file it leaves a notch that could create a stress concentration, so I have been using a curved needle file but it is necessary to increase the radius to maintain a well curved surface. This creates a slight hump. I wanted to get some feedback and possibly some photos or examples of how other handle these areas.  --->


Spark Plug Tech and Choices ...kaweeka

I added to a prior post about spark plug heat ranges after finding dry fouling on my BR8ES plugs in all cylinders. (Compression is good, 76-78/80) I run an IO 320 B1A with dual LSE Plasma III and AFP injection with 9:1 pistons. I typically fly LOP. Klaus' manual recommends the Denso IK27 which is actually a cooler plug that the NGKs in there now (the 8 heat range corresponds to a 24 in the Denso world). I wrote Klaus but, no surprise, haven't heard back. Using the 27, or even 24 when already noting fouling with the current NGK doesn't add up to me. While looking and reading, I came upon the website for Brisk Racing. There are myriad plug types and one that I am not familiar with called a multi-spark plug.

The description is this: "they produce more than one spark per impulse of the ignition system. More than one simultaneous point of ignition results in better and more spontaneous ignition of the air-fuel mixture. Spark Plug sparks are not shielded by the ground electrode; therefore it provides faster, unrestricted expansion of the flame front. The mixture burns more uniformly and more quickly. The result of better utilization of available combustion energy is more power, better acceleration, lower harmful exhaust emission and reduction in fuel consumption."

It says it is designed for high output ignition systems. Would this be applicable to my set-up? Has anyone used or considered this brand or specific plug before? I do tend to overthink things so I apologize in advance. I am NOT an engineer but want to learn and understand these questions as they arise. It makes me safer and better able to make decisions that are beneficial to my aircraft and flight safety. I appreciate any knowledge from you all.

Thanks and be well everyone,

Rudder TE Riveting Technique Question ...Randy Carmichael

First build project--having fun so far--but still in the early learning stages.

Specifically, I'll be starting soon on my rudder trailing edge. Double countersinking is done in the TE wedge, double sided tape is standing by, and everything is dimpled and ready to go as soon as I finish attaching the stiffeners and shear clips to the skins.

I've been studying ahead to the trailing edge instructions and have seen some warnings about the difficulty of achieving truly straight TE's. Also seen some posts about twists occurring in the TE as rivets are final set in the double flush fashion required. Some posts have referred to setting half of the TE rivets in one direction and half in the other to minimize twist.

OK, finally the question: Since the direction of the shop head is "builder's choice" on a rudder, has anyone tried alternating rivet direction with every other rivet in the TE? If every other rivet had the shop head on the same side, alternating with manufactured heads would that not tend to offset twisting tendency? Would it look lousy as a finished product?

Maybe I'm overthinking it--wouldn't be the first time--but just curious.


RV-10 Build First Day: Inventory Time Lapse ...Matt McCoy


Hans' RV3 - O-320 with a twist

Hi guys,

After a hiatus of about a year, the withdrawal symptoms from selling my share in the RV-4 became too much. And so I have bought myself a -3. The plane is in need of a fair dose of TLC, which I plan to give it.

Coming from a number of Subaru powered aircraft projects that are still racking up trouble-free hours and outperforming all expectations, the knee-jerk reaction was to lose the O-320 and put one of my Subaru conversions on. But I really think I'll pass this time and go with Lycoming. With a twist.

My plans thus far - and comments VERY welcome. These Lycomings are new to me ;-)

1: The plane comes with a mid-time O-320 C3B. I believe it to be somewhat of an oddball, only used on a twin (can't remember which one) in the mid-1950's. Old style parallel mounting points. 7.0:1 compression. Hollow shaft. Carburetted. I don't fancy buying a new engine and then try to get this one off my hands. So the plan is to keep this engine as the starting point.

2: As much as I'd love to go all-out, paying 13K for a C/S prop is not in the books for this plane.

3: I want to run mogas in it. 100LL costs upward of $12 per gallon here, even in this economy. Mogas is still $7-ish per gallon, but gets things within the realm of affordability. Mogas here is 98 RON, which is about 93 in US measurements.

So, the plan for the engine:
Take the cylinders off, do a valve job, check the valve guides.

Change the pistons for 8.5:1 items. I was thinking of the ASC75089F from Combustion Technologies. (what's the word on their products?). I believe 8.5 is about as far as I can go with Mogas, right?

Do I need thick piston pins for these?

Then - Can I fit new rings, or should I then also hone the cylinders?

Injection and ignition will come from two Link ECUs:
Each tank will have its own high pressure fuel pump (preferably IN the tank to eliminate all vapour lock issues) and fuel return line. Each side will have its own fuel rails and fuel injectors. And its own ECU.
Each ECU will also run its own set of ignition coils and (automotive) plugs.

Since you don't want both ECUs injecting fuel at the same time, two externally connected switches (to eliminate any single point of failure) will kill the power to the injector drivers of one ECU at a time.

There will be no more fuel selector valve. The ECU that is at play for injection determines from which tank fuel is used.

Each ECU has its own battery en bus. Batteries are fed from the alternator through a FET coupler.

So basically the only thing that is not redundant is the alternator. I can live with this. If it fails, I'll have two batteries to run things until I land.

If anything else fails, it will be on one site. I then also lose the availability of the fuel in that fuel tank. My flying is not between Iceland and Greenland, so I can live with that.

So, to continue:
Now that the carburettor is no longer needed, and carb icing no longer is an issue, I might as well get those intake runners out of the sump and get some cold air into the engine, rather than lukewarm. So I'll weld up a new oil sump and new intake manifold, with one big throttle body, and some ram air.

And yes, I know. There are vendors out there who deliver excellent products for what I am thinking of here. A few of them are even RV pilots. It's just that after half a dozen engines (including a 600 hp Ferrari V12 in a car project), I feel up to the challenge of developing my own mouse trap.

So... What do you guys think?

Oh, and what power output can I expect? I figure coming from 150 hp, the 8.5:1 will give me 160. The fuel injection and more accurate and stronger ignition 5, the cold air induction another 5 and maybe a handful for better flowing of the intake? So between 170 and 175? Or would that be overly optimistic? It would be somewhat important when ordering a prop from Catto...

I'm Back From My Camping Trip ...roofus4

I just want to thank everyone who helped me learn how to camp out of the RV. I had a wonderful 2 week long trip. All the equipment I bought as recommended by you guys worked out great. Big Agnes Copper Spur HV UL3 tent someone suggested, was perfect!

I started in Escalante, Utah (1L7) as suggested by a gentleman on this site. From Houston I made one fuel stop in Double Eagle (KAEG), before Escalante. What a nice setup. Along with a nice campsite, they have a shower and covered pavilion with gas grill, and running water. Great 1st stop to get my camping feet wet. I had the whole camp to myself, and more importantly, the courtesy car all to myself! I spent 4 nights there and did a hike a day for 4 days. It was beautiful. Might I add that May is a great month for Utah. No bugs, yet comfortable during the day, nice and cool at night.

Then, wanting to get a little more hardcore, I flew out to IBEX Hardpan to spend a night on the dry lake. It was a very unique experience. It was fun to land on such a wide open space. It was nice and smooth, however, the chalky dust gets on EVERYTHING! My shoes, my pants, my tent, my tires, my wheel pants, etc, etc, etc...

Ok, Now here's the rest of the story.  --->


PnP Flight ...mchargmg

We flew our first Pilots N Paws (PnP) flight this weekend. We went from KFLY down to Sundance airport (KHSD) on the outskirts of Oklahoma City to pick up some kitties. The momma and kittens had been living in an oil field, which is scheduled to get sprayed with poison to get rid of weeds. So a local rescue operation managed to catch the momma and two of the kittens.

We flew down to Sundance (quite a nice airport by the way!), ate a quick lunch, picked up the cats, and flew back. We were going to deliver them directly to the rescue operation in Denver at KBJC. However, the weather did not cooperate, so we landed back at KFLY, and drove the kitties halfway up to Denver, meeting one of the volunteers halfway.  --->


Smoke System Fiddling ...RV6_flyer

I removed and sold my smoke system but will comment on my experience.

Most smoke system sellers will tell you to put the injection pretty close to the exhaust port on the engine or where two or more runs from the exhaust valve comes together.

I originally installed one injection nozzle after the intersection of the #2 and #4 exhaust pipes coming together.

One injection nozzle on a 4 cylinder engine with only two cylinder exhaust created puffs. Not a big deal 75 or 100' behind the airplane but one could tell at less than 50'.

I added a 2nd injector BUT because I had a heat muff on that side, I added the inject port AFT of the heat muff or less than a foot from the end of the exhaust pipe. No difference in smoke.

When I replaced cylinders at 2,200 hours, I also installed a new exhaust system. I put both smoke injectors less than one foot from the end of the exhaust pipes. No difference in smoke output than there was before the change. Both injector ports were a few inches forward of the firewall in the top of the two exhaust pipes.

In other words, the difference in exhaust gas temperature for smoke oil vaporization is not much difference between the engine exhaust port and the end of the normal Vetterman crossover exhaust system.

Now it would be nice to instrument an exhaust system every one inch or so to get real data to actually find out how much exhaust heat is lost from the exhaust port to the exhaust pipe end. Would even be great to just use a 2nd EGT probe in the same run near the end of the exhaust pipe.

Typically the EPA recommends vaporization as the way to dispose of the smoke oil we use. Injecting it into the exhaust does the vaporization. The temperature that the oil requires to vaporize is lower than the exhaust gas temperature. Complete combustion of the air / fuel change leaves little oxygen to start a fire in the exhaust from the oil injected.

Roundtrip to Florida (again)...airguy

Didn't get any decent pics this time around, but it was time to go pick up the 172 from Jesse Saints place after the new panel install. My uncle and I departed Friday afternoon and overnighted in New Orleans, landing at an almost completely deserted KMSY. Signature did us a solid good deed there, handling everything as requested and giving us a courtesy car overnight because "ain't nobody else here and we won't need it" - and indeed he was right, the whole airport was deserted.

Ate way too much good food at Kenner Seafood Market just around the corner, and flew out in the morning for X35. Got the 172 and did several local area test flights, watched the SpaceX launch (unfortunately on the iPad rather than close enough to see it in person) and then launched back for KMSY again for the evening - for more good seafood and Signature continued their outstanding service for us again. Fought thunderstorms the whole way and snuck into KMSY right between two major cells, and then fought thunderstorms all the way back home Sunday morning. Headed out for Lago Vista KRYW for cheap fuel but the pumps were down, so we hopped to Georgetown KGTU and topped off there, and then headed for San Angelo KSJT to drop off the 172 with our local shop for annual, then home.

"Always wanted a -3B, thought about building one... ended up buying one.

Built in the UK by Ian Glenn and first flown in 2004, it was his second RV build and a masterpiece of metalwork. It's been perfectly cared-for by its last long-term owner for the last 12 years.

Powered by a 115hp O-235, it weighs 740lbs empty. To quote my friend who flew it home, "This a hoot!""


Today's Engine Puzzler ...DavidHarris

I had an engine puzzler that kept me occupied for two months. I'll post the story and clues (and red herrings) today, and then follow up with my solution and reflections in a few days.

In March I received the airworthiness certificate for N47HM, an RV7-A with a Superior XP-IO360 engine, dual PMAGs, and a Precision Airflow fuel servo.

About 8 hours into Phase 1 testing, my engine quit during stall testing (at the top of a stall at 48 KIAS, with partial flaps). Much to my surprise, it would not restart in the air despite playing with the boost pump, mixture settings, throttle, and starter, and pitching the plane down to increase the windmilling. I shut everything off and made a forced landing on the sandy bed of the dry Mojave River. Fortunately I landed into a good headwind, the sand was firmer than usual because of recent rains, and I held the stick full back, so the nosewheel didn't touch until I had come to an almost complete stop. The aircraft was undamaged. On the ground, I observed the right PMAG switch was off. I likely bumped it while entering a transponder setting during turbulence, although it is not impossible that I failed to turn it back on after turning it off during my runup test.

I had been on flight following and had reported the engine out to ATC. On the ground, I called the Victorville tower, and they sent the fire department out to meet me. I jogged about 3/4 mile to the nearest named road, met the fire department and sheriff, and then talked with the FAA. All was well, and they referred me to Jack Vanderman at Southwest Aircraft Recovery.

My family came up to meet me. The area was dubious, with burnt-out houses and ranches resembling junkyards. I found a sandy service road on the riverbank that reached within 150' of the airplane, and spent the night there in my truck to guard against looters. In the morning, I met Mr. Depue at Depue Airpark, a private dirt strip near Barstow, and got his permission to tow the plane over there. Jack Vanderman arrived with his flatbed trailer and aircraft crane, and we spent about 6 hours winching the airplane out of the riverbed, up the embankment, and onto the flatbed, then winching the trailer along the sandy road until it was firm enough to drive. He carefully drove 10 miles on Old Highway 66 to Depue, and the police car that passed us in the other direction kindly didn't bother our odd caravan. Jack's elderly father and my 14-year-old son both helped with the recovery and it was quite an adventure for four generations of aviators.

In hindsight, I would have done stall tests at 7000 AGL over Dagget airport rather than 3000 AGL over the desert. I would have looked for a dirt road rather than a riverbed. I would have aggressively tracked down engine issues on the ground before flying. I was thankful to have taken glider training last summer and to have memorized the emergency checklists and thought about them deeply. I was grateful for the help from the FAA, the Victorville Fire Department, Mr. Depue, and Jack Vanderman.

Two days later I went back to Depue, removed the cowling, did a lengthy inspection, found nothing unusual, put it back together, did a runup, and then departed the short dirt strip and flew back to my home base at Cable Airport. Flight was normal.

I had observed some issues during Phase 1 testing before the incident, and didn't troubleshoot them on the ground as much as I would have wished because I feared long ground runs while breaking in the new engine.

* The engine would sometimes quit during the rollout after landing when I was at low RPM. I attributed this (not quite correctly) to the idle being too low. Adjusting the fuel servo idle to 900 RPM prevented the problem, but caused a long landing, so I had set it back lower for further testing.

* The engine was also sometimes very difficult to start, even though I felt I was following the Superior and Precision instructions. Sometimes I would have to prime and crank up to 6 times, following the cool down instructions for the Skytek starter.

After recovering the airplane, I contacted Superior. Bill Ross, VP of Product Support, took decisive steps to help, at no cost to me, and gave instructions for testing before further flight. I wiggled the wires while monitoring the LEDs on the PMAGs to verify connectivity. The grounds both go separately and directly to the aircraft central ground stud on the firewall. The power lines go through test switches on the panel to a short shared wire going to the main power bus. The kill lines go through the key switch to ground. The PMAG LEDs turn on when the power line is at 12 volts and the kill and ground lines are properly grounded, showing connectivity. Aggressively wiggling either end of the wires on either PMAG wouldn't turn the LEDs off. I then removed the PMAGs and sent them back for bench testing. I removed the fuel servo, spider, and injectors and sent them back to Precision Airflow for bench testing. Everything came back looking normal. I reviewed the excellent Dynon engine logs and observed 0 RPM from both PMAGs after the engine failure, even though the prop was windmilling, which is an indication that the PMAGs were not powered up during the descent, despite have internal alternators that should provide backup power. I spoke with Brad at EMAG and Alan at Precision and both were very knowledgable and patient and helpful, but none of us could find a theory that explained all the facts. I was impressed by how all the vendors stood behind their products and took the time to walk me through everything even though I'm not a mechanic.

I reassembled the engine, changed the oil, replaced all the spark plugs, and started the engine again. Starting remained difficult at times. Superior confirmed from the engine logs that the engine break-in was satisfactory and that it was ok to do longer ground tests. I tuned the idle throttle and mixture settings using a screw and thumbwheel on the mixture servo, in consultation with Alan at Precision. I had a difficult time getting the idle right; if I turned it much below 800 RPM, the engine would quit at idle, while the manual called for 700-750 RPM idle. After a bunch of testing one hot afternoon, I finally found a setting at about 840 RPM where the engine would never quit on the ground at idle. Out of an abundance of caution, I waited until the cool morning to fly the aircraft. My son stood by as an observer with a fire extinguisher, and I started the engine again, but found the engine quitting when the throttle was pulled back to idle. I spoke with Alan again and he was puzzled and said there was no known temperature sensitivity for the idle RPM. My son adjusted the idle higher. Then I found the engine wouldn't start at all despited repeated priming and cranking.

Then my son told me he saw something. His statement was the clue that resolved the whole mystery. He and I made a small fix, and the aircraft has been starting, idling, and flying well for two weeks since then.

Happy puzzling,

Fuel Tank Rivets Seeping Fuel ...Jim Kranich

Q:  I've been flying my RV-7A for a year now and have just noticed about 10 rivets in the fuel tank are seeping fuel, causing a bubble in the paint around the rivet head. Most of the problem rivets are on the top side of the tank and a few on the bottom. Has anyone experienced this and if so, what's the best fix?

A: (DanH) Can't speak for consensus, but the statistics are clear. Paint blisters over tank rivets has nothing to do with MEK application. Nor is it strictly a QB tank problem.

Jim, roughly speaking, when were your QB tanks assembled?

BTW, it is not difficult or risky to install access ports in the rear bulkhead.

4-ship Fuel Run / Practice

Wednesday morning in nearly 00000KT conditions on the way out.  VIRGA in area and wind shear on the way back.  Lead changes, PO and rejoins, yada yada.  You know the drill.  Good times.  Seven of the last nine days I've been 'simulated client #1' in the sim at the part time extra gig.  The RV morning was a nice change! ;^)  dr

Half Raven Install ...KHeidorn

I installed the half Raven inverted oil system a couple of weeks ago. I had been avoiding aerobatics until I installed this. The system works really well. No more oil coming out the breather and going down the belly.

The install was not too difficult, just had to figure out were to mount the can and route the oil return line. I put the can on the left side of the engine mount and I ran the return line along the left side of the engine, across the front, to the drain in the right front corner of the sump.  --->

Haste makes Waste - Oil Filter Edition ...JKevin (RV-6

Looking for some advice...

I was changing my oil filter last night and got careless cutting the safety wire to the oil filter. I managed to tear the tab on the accessory case that has the hole for the safety wire. So there is no hole for safety wiring the oil filter in place now.

As a best I could do at the time, I ran the safety wire around the boss for the oil temp sender. It's secure, just not the way Lycoming planned it.

So as I see it my options going forward are:
-continue to wire around the base of the boss for the oil temp sender
-JB weld a small piece of tubing where the old safety wire hole was
-remove accessory case and repair via weld+drill, or replace acc case (I REALLY don't want to do this)
-don't use safety wire - has anyone ever REALLY had an oil filter fall off? Never had one fall off my car.
-something else I haven't thought of?

Any advice would be greatly appreciated.

Loss of GPS satellite signal while approaching in IMC ...GalinHdz

Since there was a tropical system overhead us yesterday and the weather really sucked I went to the hangar to do some minor cleaning. While listening to the tower I heard a Saratoga on the RNAV to Rwy 13 get cleared to land. A short while later the Saratoga told the tower the GPS had lost satellite signal (RAIM) and they had to execute the missed approach. They went around in the clouds and returned to Jacksonville approach.

Right then a Citation came on frequency also on the RNAV Rwy 13 approach and was also cleared to land. Right after being cleared the Citation told the tower the GPS had lost satellite signal and they had to execute the missed approach. The tower told him the aircraft before them had gotten the same indication and had also executed the missed approach. I heard them go around in the clouds and they also returned to Jacksonville approach.

A few minutes later the Saratoga came back on frequency but this time "VFR" below the clouds (clouds were now about 1,000ft) and they landed on RWY 13. Once on the ground the Citation came back on tower frequency but he was executing the ILS approach to RWY 31. They landed on RWY 31 with maybe a 5kt tailwind.

This is the 1st time I had heard this actually happen (GPS unuseable for landing in bad Wx) with one of the airplanes having to use the old fashion ILS to land. Now I am REALLY glad I still have ILS capability in my airplane and don't rely exclusively on the GPS "Magenta line".

Moral of the story... unless it is a life and death emergency situation, DON'T DO RNAV APPROACHES WITH A NON CERTIFIED GPS!

Going to rat out the lunch gang. Nor Cal guys meet up at 2O1 for some long awaited socializing.


Status Update ...David Paule -3B

I needed some small jobs for a bit, things I could work on for just an hour at a time, so I pulled out the elevators and stabilizer and in the middle of other things, for a break, have been working on the tips. This was actually part of the plan all along, to hold off on these until I was working on the composite canopy frame/fairing, because then I could do the first batch of the fiberglass stuff all at the same time.

Today, I bonded the left elevator tip to the elevator. Before getting to this point, though, it need a few things. As delivered, the tip was slightly fat. With the flanges nicely in place, the tip shape protruded .040 or .050 above the elevator surface, all over.

1. Drill and cleco the tip in place so that it fairs with the stabilizer tip.

2. Slit the tip along its centerline with an appropriately-thick cutter.

3. Make 1/2" squares of .040 for shims, each with a hole for the cleco.

4. Test fit them - okay.

5. Fiberglass over the slit, so that instead of two halves I had a tip again.

6. Drill the holes to #30 and dimple the skin and countersink the shims.

7. Glue the shims to the tip, more for handling than anything.

8. Glue and cleco the tips in to the elevator. Since here the glue is a gap filler rather than structure, it pretty much didn't matter what I used. But I used the thickened G-Flex.

9. Rivet the tips in place.

Right now I'm at step 8 for the left tip, shown, and at step 5 for the right tip.

The stabilizer tips, on the other hand, had the opposite problem. They were too skinny. I followed Wirejock's (Larry Larson) method and heated the tips to 150 F for an hour, then pressed them on to the stabilizer ends. They cooled slightly fat. I forced them into the stabilizer and clecoed them in place. Now they fit well.


SD-00001 for RV-12/12iS Reminder ...mothership greg

If I may make a point here: To state it plainly and simply, this is exactly why we published the Service Directive. The photos show a pre-failure condition. It's not possible to say how long the unit might take to fail, nor is it possible to say why your servo is in this condition, but this condition is exactly what was predicted and is the first step in the potential series of failure events that caused us to decide to take action. In the safety and risk management world, we call your investigation and discovery a success - It's the SD process working as a preventative measure.

In case people don't take these notifications seriously, this is a great example of why it's important to stay up to date on your service notifications (for any airplane type, not just ours). I'm posting Bob's photos inline here just to make them easier for folks to see. They are good visual examples.


My RV Weekend...Scott Hersha

Cincy River Rats did an 8 ship Memorial Day formation flight over Glendale, OH (Cincinnati suburb). We've been doing this for several years. This year was a little different. There was no Glendale parade. Just the Memorial Service, reading of names, 21 gun salute, and Taps. We made 3 passes over town, then went out and waited for the call in for the Missing Man at the end of Taps. Residents of Glendale were told to stay home, but to go out in their yards and look up. Timing worked out and the air was uncharacteristically smooth. One of our members was shooting video with a GoPro, but I haven't seen it. It was a beautiful day.

The day before - Sunday - my grandkids came out to the hangar for some family fun. We cooked on the grill, drove around on our golf cart, Yahama scooter, bicycles, AND went for a ride in the RV4. It was my 6 year old grandson's very first airplane ride. He wanted me to fly upside-down (I didn't). He said it was the most fun he had ever had - well, except for the Ninja Lego build he had just completed with his Dad (my son). The hangar is one of their favorite places to be. Mine too.


Moved from Bay Area to Austin...ssokol

Not exactly the kind RV fun the OP had in mind, but it works. I started out at Reid Hillview where I've been based for the past two years. Flew down the Central Valley to Palm Springs. Quick stop for gas just below sea level then on to Deming, New Mexico. From there a straight shot past El Paso to Breakaway in Cedar Park.

All told about 9.5 hours in the air. Not the longest XC I've done, but the most I've done in one day. (Not sure I still had the RV grin when I arrived.) Afternoon over the desert was bumpy, but the weather was clear all the way through.  --->

Latest RV Grin / Proud Daddy


What did you do with your RV Memorial Day Weekend (5/22/2020 - 5/25/2020) ...SPX

Certainly some of us did something with our RV this weekend!! Let's hear about it...

Friday, my wife & I flew up to Aircraft Spruce in Corona to go get some RV wheel chocks. We went up at 4,500' and it was pretty bumpy. Coming back home, I flew at 5,500' and it was much smoother. Quite windy both in Fallbrook and Corona.

Saturday, I flew down to Gillespie Field (KSEE) to help another VAF'er with some required dual instruction that he needed. From there, I headed up to Oceanside (KOKB) to get some "cheap" fuel ($3.80/gallon), then back to the hangar in Fallbrook.

Today was motorcycle riding day, so no flying.

We have a few more trips planned over the next few days too.. Should put another 7 hours or so on the RV between tomorrow and Wednesday

I made a mess....

Saturday was a FLY the FAMILY event for Butch Harrell in his 6A at Milledgeville GA (KMLJ). His daughter and 5 grandchildren were passing thru on their relocation move north to the DC area. 5 kids under 12 - I flew over for crowd control.  Late afternoon the skies were smooth and Butch created smiles on Maci-Kate


Am I crazy? Building an RV-10

I decided recently to sell my RV-14A and do another project. The -14A is a fantastic airplane, and I enjoyed the build and flying it (>100 hours). I've decided to build an RV-10 for a number of reasons. Of course some of this is just a need (addiction?) for another airplane project, but there are practical considerations as well.

I've been studying some RV-10 build blogs, many posts on VAF, Facebook RV-10 pages etc. I am leaning toward a "simple" build but I suspect I'll eventually get seduced by some (all?) of the extras and goodies - is there a support group for this?

I got lucky and found a QB kit (wings and fuse) available from a builder who ordered but had a change in situation. Stewart will deliver in a couple of weeks or so. I did QB wings and slow build fuse on the -14A. Not sure how I'll do the wiring and panel. I've been considering doing my own wiring (signed up for the next class at AEA). Panel will definitely be G3X touch/Garmin as in my -14A. I'm too far down that road to change, nor would I want to. I'm wondering if Garmin is going to update the PFD/MFD displays in the next year or two - seems like it may be time to improve the processor performance, but otherwise I'd be fine with existing displays...

I'm looking forward to learning from the RV-10 gurus and general experts once again and maybe even contributing a little to the knowledge base (mistakes and pain tend to foster creativity as we all know!).

RV-10 makes emergency landing on Monroeville highway


I got a build number today :-) ...Paul

Hi All - First post here after lurking, reading, and learning for some time. I have been whittling down my choices of what plane to build for the last 6 months and kept coming back to the 12 after looking at a bunch of other options.

I hold a PPL and normally fly a rented 172, and had never seen a 12 in person before Monday when I went up for a flight at a club here in NZ that operate one.

After a couple of touch and gos, 1 go around (wow they like to float if you are a tad fast!), a short field take off & landing, a couple of stalls, and some steep turns I was smiling away.
Needless to say I absolutely loved it and placed an order yesterday for empennage & wing kits, so plenty time to get tools and workshop sorted before they arrive.

So thanks for all your posts and first flight videos which influenced my decision to go with a 12, and apologies in advance for the no doubt basic new builder questions that will follow from me over the next couple of years

Fly over for the Hospitals in Maine ...Dvalcik -12

I work for a Hospital system and took a personal day with two my RV buddies to recognize the work and dedication they give day-in and day-out. We flew over 8 hospitals thanking the healthcare workers during the trying times.

Round trip was a little over 200 nm around Maine. It has been amazing the responses after we finished the tribute. Many tears, clears, and joyful thanks from the staff at the hospitals

Weather turned out great considering we planned the mission a week ago with the Hospital. The amazing thing was how nice planning was with ForeFlight for the published times for each target. Small adjustment but we were over all of the targets +- a min.

I contacted ATC the week before to plan the trip through their air space. They were great to give assistance ahead of time and during the flight.

Thanks to Jim and Jonathan for their time, fuel and commitment.


The E-buss alt feed: a different idea ...N546RV

So I've been thinking about the Nuckolls E-bus setup, specifically the handling of having an alternate feed off an always-hot battery bus in case of a failure affecting the main bus. Bob's setup takes the same basic form everywhere I've seen it: the main bus feeds the E-bus through a diode, and the alternate feed is provided through a switch and/or relay (depending on expected E-bus loads).

The reasoning behind the diode between the main and E-bus is to prevent the E-bus from feeding the main bus and possibly popping a fuse/breaker. Bob's assertion seems to be based on an alternative scenario where two switches would be provided, and it would be incumbent on the pilot to ensure the main->E-bus feed switch was opened before closing the E-bus alt-feed switch, to prevent the aforementioned backfeeding.

However, it seems this issue can be fairly easily solved with careful switch choices, such that it's not possible to have both feed paths closed simultaneously. For example, if a five-pin relay is used for feed switching, the main bus could feed through the normally-closed contact, and the batt bus through the normally-open one. The choice of how to feed the bus is still controlled by a single switch throw, the only difference being that that switch position definitively disconnects one feed while connecting another one.

Engine Rough/Rich? ...Sam Hart

I've been chasing a problem for two or three years now, so I thought I would go ahead and throw this out for ideas:

I fly an older RV-6A 0-320 E3D L-46125-27A with a Marvel-Scheber Model MA-4SP Carb Part 10-5009-1 (nozzle drilled to 0.106 in 2002). I purchased the plane in 2010 and had no real problems, but at some point I have noticed that the engine seems to be running rich because once I take off and throttle back it gets a little rough. Leaning smooths it right out. This occurs even at low altitude.

The only change I have made that is 'suspect' is that I have installed the new style CAB from VANS. The problem 'may' have started back around that time, but I am not sure. My A&P went through the carb and found nothing wrong. I am thinking about putting the old air box back on as a troubleshooting step (a fair amount of work).

Anyone else out there with my setup seen anything similar?

Metals Trending Interpretation.....bkervaski

Looking for advice!

Just had my latest oil report from Blackstone, my metals are trending like the image below.

Note that this last sample was actually from the filter, simply got distracted by hangar visitors and missed my chance to grab some from draining.

170 hours on the engine, not sure why that's not on there. Also, there could have been more oil usage since last check, it says 1.5 but it's probably more like 2-3, but certainly lower than previously.

They commented: "No one thing is terribly out of line, but this is certainly a departure from the way things were going, so it's worth watching. Any high temps? Oil use is down a bit, so maybe metals are just less diluted."

No high oil temps, things seem to be running quite normally.

Being fairly new at what numbers are normal and what to be concerned with I figured I'd get some advice from you good folks

N717AZ Flies

After a too long of period my new RV7 took flight this morning for a short shakedown flight. The 7 is equipped with a Lycoming/Barrett 220hp IO390 and Whirlwind RV74 prop.

Avionics include AFS dual 5500T's, Garmin 750, remote Garmin 330ES, TruTrak Gemini 880, CO Gaurdian, Garmin SL40. AeroLED's, VPX-Pro, Approach systems wiring hub.

Shortly after takeoff, I lost the oil pressure and manifold pressure indications. I was sure the problem was in the connectors for each. I rejoined the pattern and landed. Sure enough the connectors had come loose. They were fixed and a full inspection done. More flying in the morning. The 18kt direct crosswind now is keeping me flying.

I cannot thank my friend Ron Moring enough for his help and prodding to get the plane done. Also, Rob Hickman, Tim Haas and Stein Bruch for their continued help and patience while getting everything set up.

More later!!

Conundrum: Too much technology ...ROSSIM

Over the past few years, I have updated my purchased -6A from this:

to this:

and it has become a wonderful, fun, fully capable airplane. There is not too much this airplane cannot do ------ unfortunately, the technology has forced my partner (a really wonderful guy who loved his T-28, his T-6, and, our -10 and the -8A!) to not fly the airplane unless I am with him! ("too many buttons").

So, I have three (?) choices -- sell the airplane and get something more "steam gagy", trade the plane for a basic 8/8A that someone wants to move to a side-by-side, or---modify my panel by removing the (wonderful) screen and put in some more basic stuff -- and, yes, I know -- The AFS 5600T will display steam gages, but that requires some button pushing (two), and I also know that if I could get him to train in the current plane for a few hours, his fear of the technology would be tempered.

But, as much as I love the airplane, the way it is --- I will do something to help my partner get back to flying. So, right now I am looking at removing the screen and using that space to put in some semblance of steam gages surrounding maybe a G5, MiniX, or a even a D3. No buttons would have to be pushed and I would still have a capable airplane for VFR/IFR.

Anyway, something for me to think about other than virus stuff!

Stay safe, out there!



Weight and balance limits adjusted for RV-6/6A/7A/9A ...mothership

We've published a handful of updates related to weight limits on the RV-6/6A/7A/9A aircraft.

Change to Max Recommended Gross Weight for RV-6 (taildragger only)

The first published change is to RV-6/6A Manual Section 14 (Weight & Balance). The change raises the recommended max gross weight for the RV-6 to 1650 pounds (this is a 50-pound increase and is now the same max gross weight as the RV-6A). Previously the RV-6 recommended max gross weight had been published at 1600 pounds. The RV-6/6A aerobatic limit (1375 pounds) does not change.

Why were these numbers different in the first place? When the RV-6A was created (after the RV-6 was already available), the structure was tested to a higher value to accommodate the slightly-heavier airplane. Structurally the two models are essentially the same from a max gross weight perspective. We are issuing this change to reflect that fact. And yes, we do realize it's been 35 years.

Removal of Nose Wheel Weight Limit on RV-6A/7A/9A with U-00019 Type Nose Gear

In addition, the max nosewheel weight for the RV-6A/7A/9A has been removed for aircraft where the new-style U-00019 nose gear leg (released in 2019) and engine mount are installed. In that case, the weight limits are instead determined using the aircraft's overall weight and balance envelope. The new design was specifically tested prior to release around a worst-case forward CG loading scenario, and it was determined no limit is necessary other than the standard W&B envelope boundaries. We stated this year with the release but did not update Section 14 of the plans for each airplane, so we are formalizing that now.

The relevant documents are linked below:
RV-6/6A Section 14 (Rev 3)
RV-7/7A Section 14 (Rev 2)
RV-9/9A Section 14 (Rev 5)

Rudder Bend, Need More Bend ...Mike G -8

Looking for advice on how to get more bend out of my brake. The rudder is nearly there but I just can't seem to get the final pinch to get it to lay in the proper position on the spar.

With the rudder in the brake and just the weight of the board, the rudder is perfect but as soon as the brake is taken off it springs back to about 2" of gap too much.

I started with 2 2x8" boards as Vans suggests. That didn't seems to give me the results I needed so I switched to 2 2x4"s made out of cedar, hinged on the 4" side so I was only using the small sides to do the squeezing. That didn't seems to help so I tried this final setup witch is a 2x4" along with a 2x8".

Using the brake I can push the rudder all the way down until the stiffeners are touching the opposite skin, so I can't physically bend it any more than that. But it doesn't remain there after the brake is taken away.

I got to thinking could the vinyl backing be causing it to not bend all the way?

I would appreciate any advice.  --->


To Tailwheel or not to Tailwheel ...rockitdoc

Tailwheel easier to build?
More legroom up front?
Visibility in -14?

I'm mostly (95%) going into and out of paved runways, so no real advantage, unless it's easier, leg roomier, visibility isn't impaired, lighter, faster, and uses less fuel.

Corse I've never flown one, so that's another reason to do it!

Any MAJOR downsides to tailwheel besides risk of nose-over on hard braking?




New AFS panel installed, special thanks to VAF'er bruceh ...SPX

Today I flew my RV-9A back home after having it down for the last four weeks while VAF'er bruceh installed a new AFS panel in it.

We (really, Bruce) removed the panel and all contents (Dynon D100 and D120, Garmin GPS 496 and GTX 327, Icom A200, and aileron/elevator trim indicators), pretty much all of the wiring in the airplane, and fixed some build issues along the way.  --->

I will say the time flys.

Finishing Kit, Part 1 of 100 ...PilotjohnS

So it is time to start the finishing kit. First up is the canopy. It seems nothing has caused more trepidation from those who have gone before.

So I dive in.

The roll bar is attached first using special spacers. These have to be drilled to match the holes in the canopy rails. I drilled a pilot hole first, then flipped the spacers over and drilled the final hole from the "backside". I did this to avoid the drill bit wondering due to the "split level" top side.  --->

Over to KXBP for gas in 00000kt conditions.  Woke up to (3) RV-8s in the local air, if you trust the interweb, so it was out to fly before it got bumpy.  On the way back I went over a school (SE of Bridgeport) where it looks like some of the students have decorated their teacher's parking spaces.  Sure made me smile.

Wind Shear Video ...VAC

We were flying some AOA software tests last week and had a camera installed to record the standby airspeed indicator along with the normal forward view. My home base is a tree canyon close to the Gulf Coast 5 miles east of Eglin AFB in the Florida Panhandle. Winds were light on the surface (80' MSL), variable around 090 degrees or so at takeoff, but I encountered over 30kts at pattern altitude. As I climbed through about 3500' MSL, winds dropped off to light and variable. This abrupt shift in velocity in such a small altitude band meant the chance for wind shear would be high during RTB, and sure enough, it was: https://youtu.be/0RiB6_8bx3c

The important thing to note is how rapidly the bottom dropped out in the transition and flare. Stable is a relative term under these conditions in a light plane. I was flying a slight fast approach (high rate beeps of the tone) and transitioning to ONSPEED during transition to landing. The AOA tone provided good SA throughout, but it was sporty. If 15 kts of rapid shift is "severe" wind shear, this event was close. If shear results in a rapid loss of airspeed, it's called "performance decreasing" and if it causes a rapid increase in airspeed, it's called "performance increasing." The recent Van's EAA webinaire addressed this and I'd recommend it to anyone that hasn't watched it. If you'd like more info on our AOA work, visit our site at http://www.flyonspeed.org

N99PZ enters a new life. ...Seismo

It is with a sad heart that I inform the world that N99PZ has been sold. 20 years of flying adventures and fun surround that airplane. For 25 years she was a part of my life as the build started in Feb of 1995.

N99PZ went to an enthusiastic buyer with many plans for her. When we did the "Buyers Test Flight" the grin was there. She wants to be flown and the new buyer has put 5 hours on her in two days. N99PZ likes this. Flying is what she was built for and I was not flying her enough.

The new owner and his 17 year old son are both pilots. They plan on taking N99PZ on many memorable adventures as I and my wife did. A new chapter has opened for N99PZ.

I am so Happy for her

Safe flights, N99PZ

Van's Announces Approval of Lycoming IO-390A for RV-7 and RV-8 ...mothership

Van's Aircraft announced today that we have reviewed, approved and are now selling Lycoming IO-390A (210HP) engines for RV-7/7A and RV-8/8A aircraft. Support for installation is limited since we do not have a FWF kit specific to this engine. Many community members have used this engine on their 7's and 8's already.  --->


-3B Update ...David Paule

Well, for better or worse, this plane has a canopy. After a few lost work sessions deciding if I could form the inner flange before gluing the outer one, and deciding the day I was ready to try, that I couldn't - I glued the outer flange to the canopy.

I'd planned to glue it to the fairing at the same time but realized that was unnecessary. So at this moment it's taped and clecoed to the fairing. For that matter, there are a few clecoes through both the flange and fairing right into the turtledeck skin. I had no other way to hold things in position.

Here's the canopy glued with the black electrical tape still on. I removed the black tape shortly after this photo.  --->

Visited Blackbeard's island hideaway-Ocracoke Island ...AAflyer

An amazing day on Saturday in the East brought many planes out and about. The Mrs. & I headed out in our RV-8 to Ocracoke Island, in the Outer Banks of North Carolina for another fly-out picnic. Saturday was the island's first official "open" day, and folks were streaming out to the beach by ferry and plane. The airport, W95, located in the National Park, is in great shape, with room for a couple dozen on the ramp with tie-down ropes. It was filled to over capacity this day, with several planes pushed onto the grass. Most businesses were still closed and re-building from last year's flooding hurricane. The golf cart rentals ARE open, and some eating establishments have take-out during limited hours. At least one hotel was open, but since we didn't spend the night I did not ask about their services. CALL AHEAD for everything, as this info changes by the minute. DO NOT RELY ON WEBSITE INFO! The little Ops building is back in operation with WIFI. No phone that I could see. My Verizon iPhone worked well. Two Port-a-Jons at the airport gate. No running water.
We got picked up by one of the friendly owners of Wheelie Fun golf carts..spent a little time touring the town of Ocracoke, but very little was open...they are all working hard to get things in shape, though. If you're not carrying a lot, you could get away without the cart...town is only a 15 minute walk from the field. We ended up having our picnic at Springer's Point on the beach in the speckled shade of knocked down and dead cyprus trees. After lunch, we returned the cart and got driven back to the airport, (no carts are allowed to be driven outside the town limits) where we swapped our lunchbox for beach towels, and joined the "crowd" that was streaming to the surf, only a few hundred yards from the ramp. It's a 'drive-on' beach, so there were several trucks, fishermen and families enjoying the water.

I would suggest a close study of the sectional, so you do not bump into one of the MANY Restricted Areas used by Cherry Point Marine Corps Air Station...Osprey training!!! Use Cherry Point Approach Control if able.


Yosemite ...rcsilvmac

RV 4-ship into Sydney International ...newt

The Australian state of New South Wales rolled-back their stay-at-home order for COVID-19 on Friday, so it's the first time we've been able to get out and fly airplanes in two months.

With the airlines all but shut down, there are suddenly a lot of idle arrival and departure slots at Sydney International. What better way to celebrate the relinquishment of the lockdown than by using one of them?

Eddie Seve spent several weeks doing the legwork to organize it, coordinating with ATC, Sydney Airport Corporation's media unit, and the slot admin people at Airport Coordination Australia. Glad I didn't have his job.

The result was a departure from Wedderburn in the South of Sydney, receipt of a clearance from Sydney Centre to climb to 3000 in Sydney's class C, then handoffs through Sydney Approach, Director, and Tower for a visual approach to runway 16R at YSSY.  --->

Safety Directive SD-00001 for RV-12/12iS - Elevator Trim Servo ...mothership

Van's Aircraft has published RV-12/12iS Safety Directive SD-00001. It includes a simple inspection and modification of trim tab motor units included in RV-12/12iS kits shipped prior to the publication date (May 14, 2020).

Safety Directives are considered mandatory in nature. This safety directive does not immediately ground existing airplanes, but does require a simple inspection before further flight and action to be taken at next annual condition inspection or by a specified time in service. Details are in the document.

Synopsis of what owners need to do:
Examine the stabilator trim motor installed in your aircraft and determine which model is installed.
Examine the metal shaft on the trim motor to determine if it is bent.
If bent, order the replacement trim motor and bushing parts described in the document.
If not bent, determine which of two trim motor models is installed.
For the older (no longer shipping) model, replace with the new model if time in service is 1000+ hours. You may, of course, replace the unit before that time with the new parts as well. Note that the Ray Allen Company, which manufactures the units, has set up a low-cost exchange program for affected units of the older model. Details are included in the Safety Directive document.
For the newer (current) model, order a small and inexpensive bushing kit which MUST be installed before 1000 hours time in service. NOTE that Van's STRONGLY encourages installation now or at their next annual condition inspection since it is a simple, inexpensive and safety-related change.

Today's Top Tip: Sealing Cowl Heat Barrier ...goatflieg

I'm sure others have tried this, but I wanted to share my positive experience.
Yesterday I spent seven hours cutting and applying the aluminized heat barrier recommended for the interior of the bottom cowl, which I bought from Aircraft Spruce. It is recommended that the seams and edges be sealed with high temp RTV, but before I did I conducted some tests using aluminum tape. The results were promising, so I went ahead and sealed all the seams and edges with the aluminum tape. I used a plastic roller (bought for fiberglass layups, but never used for that purpose) to firmly press the barrier material onto the epoxy layer applied to the raw interior the day before. When I used the roller to also apply the aluminum tape, it worked perfectly to bond the tape and blend it into the panels. I'm hoping the glue on the aluminum tape will hold up to the heat exposure; it is designed for HVAC applications so it should. In any case, the results are far better than expected. It's been awhile since I had a genuine "Yee Hah" moment in the shop... but this was one of them.

The ever changing fuel flow ...bjdecker

Some background -- My RV-7 has a YIO-360-A1B6 with Dual Plasma III ignitions, Garmin G3X Touch system, with the EI FT-60 "Red Cube" fuel flow transducer located in the fuel line between the engine driven pump and the fuel servo inlet, almost the same location as per RV-14 plans (page 49-05).

Over the past 115+ hours, I have never been able to get a stable or accurate fuel burned total from flight to flight. I'm always adjusting the K factor (mostly up) by a few % after each fill up.

For example, I started with 68000 as the magic #, flew for a couple of hours with various power settings, filled up the tanks - Pump at airport said I burned 15 gallons, G3X said I burned 13.5, adjust the magic number. Wash-Rinse-Repeat, Pump says I burned 21 gallons, G3X said I burned 22.6, and so on/so forth.

Here's a picture of my installation. Any suggestions would be appreciated.

Covid-19 Sanity Trip to the Pacific and Back ...james_bakeman

I was itching to get up and go after weathering another long and cruel Michigan winter. My brother-in-law and I headed out on a therapeutic trip west from Michigan to the Pacific and back.

We crossed the mid section; Stayed nights in Rawlins, Wyoming, McCall, Idaho, Reno, Nevada, and North Platt, Nebraska. The weather was great the entire way until we hit slow moving IFR in Iowa on our return, necessitating a deviation north through Michigan upper peninsula and across the Mackinac straits to return home to Lowell, Michigan (no interest in flying across the Big Lake!).

This is my first post regarding this great plane: power, speed, and comfort over the great plains, the foothills, the desert and mountains and the coast: just a fantastic experience the whole way!  I am really looking forward to more adventures this summer! - Cheers!  --->


My RV Weekend**** ...TomVal

*I'm retired....every day is a weekend. <g>

I headed to the airport this morning with the best of intentions...to drop the cowl and complete some fiberglass work on the air inlet ducts. Well...that didn't quite happen today.

When I checked in with Charleston Approach for flight following with just my callsign, they immediately gave me a squawk code and never asked me to confirm my altitude nor where I was going...pretty laid back I guess! So I flew counterclockwise around class Charlie and did the beach tour. Landed 1.2 hrs later.

Parked and de-bugged the -12, had lunch with some friends, pulled the cowl, then went home. Fiberglass another day!


FINALLY DONE........ WELL 99.99% ANYWAY......



New Kid on the Block

Greetings All.

Just thought I'd introduce myself to this bunch since I expect I'll be spending a lot of time here and asking more than my share of (stupid?) no, lets say basic questions.

After lurking around, asking a few questions, and almost ordering an RV-7 kit I finally bit the bullet and placed an order for my RV-14 empennage kit. It ships today! I'm stoked.

Some of you folks have already answered some of my inquiries and I've even had a couple offers to let me come look over RV-14's here in Florida. Thank you. If anyone in the Melbourne area has a -14 I'd love to hear from you too.

By way of that introduction, I'm a lifetime Bonanza pilot who keeps his P35 here at KMLB. Lord willing I don't expect that to change--certainly not as a result of taking on this project.

I stay instrument current since I just put all new glass in the Bo and I love the challenge of weather flying. I also enjoy working on my toys just about as much as using them, which is why I got my A&P a couple years ago. Just for amateur/recreational use.

My goal here, as mentioned in another post, is to have a challenging long-term project and to hopefully get to the point of flying it to build tailwheel proficiency and explore the edges of the flight envelope a little more. Much as I love the Bo, it's not very well-suited for either of those missions.

So, thanks again for the help and advice so far, and please be patient with me as the questions start to roll.

If you're a 14'er in the Brevard County area, or if you're planning a visit I'd love to hear from you.

Please critique my electrical diagram ...Keith Ward

I'd like to get some feedback on a wiring diagram that I'm trying to finalize.

Full disclosure: this is for my Panther LSA build and not for an RV, but I do think it would be applicable to anyone that is at this stage in their RV build. If it helps, I have built two RV7s, partnered in an 8, and helped friends with two RV-10 builds. I also try to add value when I can here on VAF. And, for what it's worth my engine for this build came off an RV-4 that I bought from a fellow VAF member, so my Panther is sorta-kinda RVish. If the moderators still think this is an out of bounds post, then please take it down.

So here is where I am so far. I have taken the Aeroelectric Z-11 diagram and changed it to include a B&C alternator w/ B&C external voltage regulator. I've also changed to dual PMags and a push button start switch.

The questions that I have are:

Do you see any mistakes or issues?

Would you take any of the components that I currently have on the endurance bus off and move them to the main bus? Rationale would help for learning purposes.

How do I figure out the best wire and fuse size for the wire that goes from the battery bus to the ebus switch (that wire will be less than 12" inches in my application)? Aeroelectric shows a 7amp fuse with a 16AWG wire, but my equipment list for the ebus is different, so the amp draw will be different vs the original Z-11 drawing.

Here is the link to my diagram:

Thanks for the help!

Vertical Stabilizer Forward Spar ...Jarrett

Just started working on my 14A empennage and I seem to of already made a mistake... I was match drilling the reinforcement plate to the forward spar and I got to the hole that was supposed to be match drilled to 1/4 inch. Through my reading I've read that for bigger holes it is best to use a unibit to avoid the metal catching and hole distortion. I ended up going too far resulting in the reinforcement plate being chamfered, and the hole on the spar being distorted. Starting to question my choice on using the unibit... Is there anyway to fix/adapt or should I order new parts?

RV-6A Status ...PaulvS

Started on fuse skins.  It was quite a battle to get the aft side skins fitted onto the fuselage. Initially, the curved over section of the long side skins was not rolled enough to properly fit over the belly skin. So I clamped the edge of the skin between some boards and gradually curled it over to get it to fit better before starting to drill it on.

Once the sides were drilled, the next challenge was to eliminate ripples in the belly edge of the skin due to some bulging bulkhead and alignment problems. Thanks to VAF and some helpful folk I found a solution, this took about a week to work out.  --->

Q: Recessed instrument Panel ...JohnD.TF4

Greetings all!

I had an idea for a recessed or "tiered" instrument panel if you will for an RV-8. The idea came from military jets which have their PFD information (usually in the form of a HUD) and a primary FMS (knob, button, switch) panel spaced off of the main panel closer to the pilot's reach and in the center of your field of view.

I am also considering a recess or cutout for my knees. While it's not a huge inconvenience, my long legs do get caught up on the panel getting in and out.

Does anyone know of any RVs out there with modified instrument panels with extra cutouts, angles, tiers, etc.? I'd be interested in this kind of mod done to any model RV. Pics would be great.

P.S I didn't know what thread to put this under, but it seems like all of the panel nuts like to congregate here so here goes.

Thanks and happy flying!

My 2007 RV8 'Borrowed Horse' has been gone for a year now. After 750 hours of pure fun flying, I still miss having that plane. So...

I am building again. I found a Fuselage and Empennage Kit close enough to take a look at. The construction / workmanship are perfect as can be. I bought it. It's here now and I'm on it.  It will need a wing kit and it came with a Show Planes Fast Back Kit that I will not use. It's Uncrated and un touched....

My original program would take the CSV file recorded from flight, calculate some statistics, graphed various parameters and plot your flight in Google Earth. Example of graphs shown below.  --->


VOR antenna and my GTN650 ...tcoverst

Having trouble getting my VOR/ILS antenna showing signal on my GTN650.
The setup is flat antenna in the copilot side wingtip. BNC cable directly from the antenna (ring terminal connectors) to the back of the gtn650 (bnc connector).
It could be
1. The Antenna itself
2. The BNC cable run or connections
3. A menu item in the gtn650
I have checked the connections on the antenna and they are tight and solid. The cable was continuity tested when installed.
There is no signal when I try to tune a VOR or catch an ILS. Its not intermittent signal, its just no signal at all. The GTN 650 works perfectly for RNAVs and other gps navigation.

Open to any input someone may have for where and how to troubleshoot any aspect of this system. Particularly, I am wondering if there is a gtn650 menu item that needs to be selected or something simple like that - maybe the g3xpert can weigh in?
Thanks for any assistance or ideas you have. Its in the hands of the braintrust now - no problem stands a chance there!

RV-7 vs. RV-14 Decision ...Florida Boy

So here's the new builder just about to pull the trigger on a -7 empennage kit. Looked at several, sat in a few, and even at my 6'3" 250lb size had convinced myself I could fit. Cozy, but doable.

Last minute doubts set in. The larger cockpit size and MTOW of the -14 just keeps nagging the back of my mind.

Sure, I'll have to dig up another mason jar in the back yard for the budget increase, but I've begun to wonder if the comfort and overall usefulness for a guy my size won't be worth the extra AMU's.

Looking for the brain trust here to help me out:
Anybody got time and/or experience with both the 7 and the 14?
Any completed 14's in the central Florida area that would be willing to let me take a peek at their plane?

Thanks in advance for any advice you'd care to offer.

My RV Weekend ...crabandy

My brother has been furloughed indefinitely, instead of waiting around he decided to get back into trucking. He'd found the right truck for $6000, only problem was he needed a ride to go pick it up several states away. And he needed to do it on Monday. A little planning proved it could be done, leave for the 634 nm round trip at 7am and I could be back just in time for work at 2:30pm.

Staring at the sun and making good time at 15,500, we picked up the IFR on the descent to pop through a 500' layer and landed 5 minutes early.

My RV Weekend

(Jonathan Alvord)
We went on a Covid getaway trip to Idaho! Next week is AZ, NM, UT to bring Supplies to Crownpoint NM, a small Navajo Chapter that has been hit hard financially due to Covid. We are taking 250 reusable Masks with HEPA filters, and 12-24 Qts of Hand Sanitizer. Will be flying from Washington, Idaho, Page AZ, Crownpoint NM, Gallup NM, Sedona AZ, Grand Canyon, Hurricane Utah and then returning to Washington. Should have a good video when it is all said and done.

Got my collection of three projects, lots of head scratching, RV engineering and Eighteen years young aeronautical machine I call "The X" out of its hiding place (my garage) for an evening jaunt to escape the confines of my garage, home chores, CV19 shelter in place etc. I also though Mama would appreciate a Moms day ride and a temporary respite from the humdrum.

After a nice taxi out and warm up we departed, climbing to an ear-splitting height of 500' AGL (1500 MSL) and peered out the canopy at the green landscape, lakes full of fisherman's and skiers crafts whizzing about, all at a leisurely 2000RPM (4.8gph) 125KTS. We returned to our humble abode, admired our new plants from a birds eye view and barely touched the blades of grass at our home drome, another successful patrol in the books...

Took a lap arounbd Mt. Adams and Mt. St. Helen.  Went for an AM sight seeing tour of Mt. Adams and Mt. St. Helen's, then a low approach at PDX on the way back to KMMV.


Initial Contact ...bill.hutchinson

Hi there, VAF people.

I was encouraged by a couple of RV owners to read and join here with questions.

I'm in the very early stages of identifying what I want in an RV - the biggest decision has been just getting to the point of wanting one!

I'm a part-time CFI and full-time cog in a large software machine in the northern VA area near DC, and I'm very interested in owning an RV. Right now, I'm leaning toward an RV6 or RV7, but would go with the right -A model if it presented itself.

Yes, I am looking for a flying RV - do not have the space to build one.

I'm just reading and shopping for the time being but I do have a nagging question:

How do you fine folks go about finding a mech with RV knowledge for a proper pre-buy experience? Do you post here, or in your regional forum? Is it word-of-mouth?

Just curious.

Wanted to say hello. I have much reading to do. Please be gentle as I ask dumb questions.

PA-28-180 to RV12 - Am I crazy? ...JFCRV12

Hello all,

A while back, I posted I was considering building an RV. While that's still the plan, it isn't happening anytime soon. I simply do not have the time. But I do have time to fly. As such, I bought a Piper Cherokee 180 in Oct. While I love the plane and it's very nice, I'm seriously considering a 'side grade?' to an RV-12.

Here's my thinking: My long x-country is from KHAO to KUOX (Ole Miss). That's 442 SM and likely would make 3 times per year during school year to visit daughter. I've done in my Cherokee and it's simple trip and very comfortable. I've yet to have someone sit in my backseat..net, I guess I don't need it. As I still plan to eventually build, I thought an E-LSA would be a good way to learn into the experimental world. Here are some brief pros/cons. Am I thinking about this right? Understanding the forum I'm on, I expect bias in the answers

Vans RV-12 - Pre-owned, it's a wash in terms of acquisition cost vs my PA28.

Much lower operating costs (mogas, fuel efficiency, own CIs after 2 day course)
Incredible visibility in RV-12 vs. PA28
Essentially a brand new engine vs. 15 year old overhaul
modern avionics and autopilot
Strong community and documentation (vs. other experimentals)

Touch slower than PA28
2 seats vs. 4 and significantly less useful load (PA28 is like an SUV)
Light weight means much more bouncing in turblence
TIGHT nonstop range to KUOX (est. about 17gallons assuming no wind)
Higer insurance cost vs. PA28-180?

Probably my biggest concern is the tight range vs. the PA28 and maybe the extra bouncy ride vs. the Cherokee. Any thoughts from the group? Anyone made the move from a Cherokee 180 to an RV-12 for non-LSA related reasons? How'd it go?



Initial Contact ...Felipemg

I just solo'd on my RV4 (N7071J) and I'm new to tail-draggers, 1,400 hr private IFR used to fly a Piper Malibu where my approach and landing speeds were much higher.

I'm amazed of how slow you have to get in order to actually touch on all 3 wheels and I'm slowly getting used to these new parameters.

I've seen on this forum that there are 2 lines of thought on this issue, some argue to land on the mains then to slow down to lower the tail while the other argue to land on 3 even on x-wind conditions.

So far I've landed in nothing but calm conditions and 3 wheel landings, close to stall speed, have been relatively easy to learn but if feels a little exposed in the case of gusty x-wind conditions.

Can anyone share their experience on this subject to further my learning

Thank y'all for your help

XC Trip to Replace my OSH Trip ...jhk770

This year my 15 year old son and I were planning a "Father/son" trip to Oshkosh in my RV7A. Now that AirVenture has been cancelled, we are still thinking of some kind of flying adventure. We live in New Jersey and we were thinking of a coast to coast trip or something like that, lasting 7-10 days. That being said, anybody that has done a trip like this and wants to share their flight plan and cool destinations or has ideas on where to go would be much appreciated.


My RV Weekend ...various

Changed oil then went flying. Landed on Ibex hard pan

Made the flight from Orlando to the Dry Tortugas National Park before eating a picnic at X06 Arcadia on the way home. Don't forget to call FSS to close your DVFR flight plan as they will have the world looking for you, at least thats what my friends tell me will happen. cough cough.

My wife's evening jaunt.  SC lake view and Aiken, Newberry touch and goes before she took a turn back across the lake to the grass strip in Gilbert.  Thank you to Jeanette for keeping our RV-7 flying while I'm at work.


Engine momentarily dies ...Earl Findlay

For the last 25 hours, since I finished the condition inspection, about five times now, when cruising or descending, the engine stalls out for just a split second and then comes back alive. By the time one can react, it's back and purring.

I changed the spark plugs at the last condition inspection and did a compression check (78, 78, 79, 80). Oil analysis was good.

Pmag and Lightspeed ignition.

Should I change out my plugs again? Or any suggestions where to start? Prior to the RV flying it's been 25 years since I flew. I have about 50 hours on it now. Maybe this is not abnormal and I have forgot about it? Absolutely no other trouble indications.

RV-7A Performance Upgrade ...jhiggins

My RV-7A just got a BIG performance update, and so I thought I would pass along some of my experience with that. I've owned 3 RVs in the last 14 years, but I've never built anything. I don't really consider myself a builder, but more of a tinkerer. A year ago or so I decided I wanted a kick-*** RV that I can keep for a long time. I really prefer side by side, so that eliminated owning a Rocket. I wasn't really seeing anything for sale for quite a while that fit my needs, so I decided to buy something knowing I was going to do an engine/prop switch. I found a really nicely built RV-7A with an o-320 and metal fixed prop. I decided on the Thunderbolt IO-390 with a Hartzell Composite constant speed prop. Looks really nice under the cowl with the red engine paint and chrome rocker covers, and chrome battery box. My original plan was to hire out this work, but that wasn't really working out very well. I had some spare time and decided to just do the work myself. It ended up being approx. 250 hrs work in all. I replaced EVERYTHING firewall forward, including a new cowl (horizontal induction), and even the engine mount.
A few of the options I chose are: Earth-x battery, to save 10 lbs off the firewall. One regular mag and one Surefly. Vetterman exhaust, Avstar fuel injection, Plane Power alternator. The Avstar was chosen mainly to have a straightforward install of the snorkel. And it was, just bolted up nicely with no modification. I used the RV-10 oil cooler and firewall mount (with 4" scat tube), and I ended up using the RV-14 baffle kit. The baffle kit was really nicely put together, however I had to trim about an inch of height off the top of the metal baffles to fit the RV-7A cowl.
The plane ended up going from 1078 empty to 1116 empty for a 38 lb gain. Weight and balance is good as I didn't end up coming even close to the max nose weight recommended by Vans (in all weight conditions) and I also can load it up with a fat co -pilot and 100 lbs baggage and not exceed the rear CG. I plan on putting my smoke tank back in the back in the future anyway (20 lbs) and this will help a little with the nose weight.
I have flown off the 5 hrs phase 1 and everything is great! All temps are cool, especially the cylinder temps. Performance is outstanding. Acceleration on the runway feels more like a sports car than an airplane. True airspeed seen so far is 179 kts, 75% power. I hope maybe to gain a knot or two as the engine gets more broken in and I wax her up real good . The best I can calculate I am getting at least the advertised climb of Vans 200 h.p. website numbers.
Thanks to some buddies that helped: Brad Striplin, Mike Quinn, and Tom Rood. I don't think I would have attempted without some knowledgeable help around.
If someone wants to help me I can send a pic to you that you can post as I have no online picture hosting ability.


200kt GS ...KJBSouth

Thursday 5/7 on the second leg of a relocation from Michigan to Florida, RV7 N50KB joined the club; 215 kts ground speed!  There was a 72 kt tailwind component while cruising on 59% power at 14,500 ft msl.


Seriously Considering Buying a Built RV-12 ...Piper J3 reply

I guess I need to jump in here. It just depends on what you want to do in life... I'm 67 years old, been flying for almost 50 years, and I'd like to fly a lot more before I have to put down the spoon.

So, you buy a $60,000 used airplane that someone else built. About the cost of a real nice car. Fly, enjoy, and when the time comes, sell for residual value. Try selling a 15 year old car. Banks are paying <2% interest and the stock market just lost 30%.

In the meantime, E-LSA is an incredible value. FAA allows self-cert health, you do your own maintenance, take 16-hour course and do your own Annual Cond Inspection. The only "hired guns" you need are CFI for BFR and avionics shop to certify transponder.

Once all SBs are complete, the 12 is extremely easy to maintain. Treat the engine like Rotax explains and use Mobil 4T synthetic oil with 93E10 Mogas. Rotax certified technicians at KOSH last year said you need a very good set of mics to measure any engine wear at 2000TT. No Top Overhaul halfway through TBO. Water-cooled heads and heavy cast cylinders stay "round" unlike air-cooled (i.e., quench) cylinders. Almost no oil consumption between 100 hour oil changes with Mobil 4T. Buy Tier-1 auto fuel at Costco for cheap. Liability insurance costs me $400/yr. No hull insurance - I accept that risk.

Did I say enjoy flying? So, you either sit on the ground and look skyward wishing you were flying, or, you actually do the deed. So far, I've been living the dream. Best flights have been with my triplet granddaughters. Grandpa - can we go fly in your airplane?


Status Update (RV7) ...RV7ForMe

Following up on post from last year. I finished the Flap / Wig Wag Controller.

It is much nicer now. It took forever but I feel like it is ready to test in the real thing. So far it has been my daily passenger in the car. Pretty good way to check GPS speeds and such. YES, YES, I know I wish my car had wings too.

Since I wasn't sure what switch I like best I designed it in a way that it can connect to both a rotary switch or a Momentary UP/DWN switch. Works great.

I also have integrated panel position lights. That will give me an visible position of the Flap position selected. That is especially useful for the Mom Sw.

I wish my airplane was flying so I could try this out today... Guess I'll have to find a curious fellow RV flyer.

What does it do?
-Reads GPS grounds Speed.
-Over set speed the landing lights will WIG WAG
-Under set speed the landing lights will go steady ON
-Over max flap speed the deploying flaps will not work, but the will come up if you choose so
-Under max flap speed deploying flaps will work normally
-If GPS signal is faulty, unstable or not available the systems deactivates and Landing lights go steady on and flap deployment is available at all speeds
-It will read the flap position and give it out in a format that the G3X system will read, eliminating the need for another pos sensor.
(I assume it works on Dynon as well but I have only had a G3X to test)

-System uses 0,09A at 13.5V = 1.2W
-System weighs 0.25lbs / 113g
-2x DSBUB 25 Pin (I used 2 pins per wire for the high Power items)
-There is a hookup for an external GPS antenna in case I want to mount this under the floor board next to the flap motor. So that should not be an issue.
-I will need a box but my "el cheapo" china 3d printer doesn't print any nice quality stuff. It's really just good for prototyping. ideas?

PTT causing problems ...Scott Hersha

Before I call someone at GRT, maybe someone here can help, in fact I'm pretty sure of it. On my RV4 with two GRT screens and a Garmin GTR200B com radio, I often get spurious warnings, like "EGT too High, or Fuel Pressure too High". These are visual warnings on my EFIS with no oral warning given, and no exceedences noted on my engine indication system. Funny thing is, this only happens when I key my mic to transmit on VHF COM. My PTT switch is on my Ray Allen stick grip. One wire to the PTT on the stick goes to the -200B, and the other one goes to the ground buss, located on the firewall, where all my grounds are located, except for a couple out in the wingtips for lights. Also, the CHT and EGT time graphs show a dive to zero when I key the mic. Fuel pressure indication sometimes goes crazy too when I key the mic. There is no noise in my headset associated with this. Sounds like some kind of grounding issue to me, but what should I look for? I'm thinking initially of grounding my PTT to an airframe bolt near the point of origin.


RV-12 Roll Right ...Jim Stricker input

I bought my 12 from original owner with 48TT. The airplane had a small trim tab fastened to the left flaperon with double-sided tape. It worked but the trim tab looked obnoxious and tape isn't exactly structural. I removed the trim tab and the plane flew with a very heavy right wing.

I checked and adjusted the straightness of the upper wing skin that trails behind the spar and also squeezed the trailing edge of the flaperons. Neither solution fixed the problem.

What I did find extremely effective was changing the height of the flaperon pivots. Its been several years now, so I can't remember exact adjustments, but basically what you want to do is raise flaperon pivot on one wing and lower pivot on the other wing. Perhaps start with 1/2 turn up on right wing and 1/2 turn down on left wing and test fly. Again, I can't remember which flaperon I raised and lowered. No big thing - just note the change and test fly. First test flight will tell you if you're adjusting in correct direction. If wing is heavier in flight then do opposite correction.

I believe I ended up changing pivot heights by one turn of the rod ends. One wing one-turn up and the other wing one-turn down. Plane now flies hands-off and ball is centered in cruise flight. Deploying flaps anywhere in the white arc is still hands-off level flight.


Significant EGT, CHT Difference Between C1/C2 and C3/C4 ...ssokol

In the process of testing out my engine monitor (the one I'm building) I ran a detailed log of a flight which captured some interesting facts. Turns out that there's a significant difference in both EGT and CHT between the two forward cylinder and the two aft. Engine is an IO-320 160 HP.

Max EGT Values: 1042.52, 1106.60, 1408.28, 1403.06

Max CHT Values: 322.70, 358.52, 386.42, 379.22

I fully expected the cylinder head variance due to basic airflow, but I'm quite surprised to see that the max exhaust gas temps vary that much.

Note that those are the maximum temp values over the course of a 45 minute flight, sampling at 10 Hz. The averages show much the same:

Avg EGT Values: 870.57, 946.65, 1174.19, 1187.25

Avg CHT Values: 288.47, 317.31, 335.30, 337.83

Does that seem normal, or is there something odd going on here?


Canopy Release Discussion

(PandaCub)  I .... ended up putting the canopy release handle to the right of the center stack and used a cable instead of the supplied pull rod attachment

(kbalch)  That was one of the reasons I chose to remote-mount the audio panel, Comm2, and transponder.


A smooth visit to the FSDO...SPX

Today I visited the San Diego FSDO for reissuance of my operating limitations. Specifically, I needed this change to revise the Phase 1 area. Concurrent with this change, new operating limitations were issued (I had the previous format), along with a new special airworthiness certificate. The visit went perfectly smooth.

For those buying an RV from out of the area, this is a good reminder.. in case you ever need to enter Phase 1 again, you will want to get with your local FAA rep when you buy the airplane, to get new operating limitations that cover an area near you for Phase 1. If you bought the airplane 2000 miles away, and decide to change the engine or prop later on, the previous Phase 1 area won't do you much good.

For those curious, the San Diego FSDO (or, my inspector, anyhow) likes to issue the following Phase 1 area:

Southern Boundary: The Mexican border from 116 degrees 0 minutes west longitude to the intersection with the 200 radial of the Julian VOR. Special care shall be taken to avoid Mexican airspace.

Eastern Boundary: Along 116 degrees 0 minutes longitude west.
Northern Boundary: Along 33 degrees 30 minutes latitude north.
Western Boundary: A line connecting the following radial points from the Julian VOR:

200 degrees at 49.5 statute miles to a point
190 degrees at 24 statute miles to a point
230 degrees at 24 statute miles to a point
265 degrees at 26 statute miles to a point
270 degrees at 42 statute miles to a point
290 degrees at 45.5 statute miles.

Excluding flight over any densely populated area.

Practicing Rolling [Half] Circles ...1flyingyogi

My first few attempts at rolling circles in the RV. I've done a few in the Laser as well, and it's definitely more work and harder doing it in the RV.

First flight of the first RV10 in China ...Shawn Li

Glad to report the successful first flight of the first RV10 built in China. I was one of the two crews for the first flight. The Chinese regulation allows more than one test crews that are necessary for the test flights. The first flight was a bit short due to high CHT temperature, reaching 430F so we landed in about 20 min. After about 5 hours further flight in three days, all squawks are fixed. The RV10 flies really nice now. Here are some pictures from the test flights. There is a RV14 almost complete. Hope to see more RVs, and experimental aircraft in general, in China.


Airplane Mistakes and Lessons ...tjo entry

It's amazing how much cognitive ability you lose when stressed. Back when I had maybe 150 hrs, I was asked to fly my Cessna 150 over to PDX for a Horizon Air sponsored Boy and Girl Scout aviation day. No problem, I said, but inside was really stressed about landing at PDX. Flight over went great, day went great, but winds picking up in the afternoon to gusting to 19kt crosswind had me nervous. Did my preflight, weather check, etc, distracted by the stress of navigating around the airport amongst the big boys, and dealing with the wind. Managed to communicate well enough to get all the way to the hold short line and was instructed to "position and hold". At that time, I had no idea what that meant, so I asked. The reply was to "disregard and hold position", rather gruffly. At this time the radio chatter was coming hard and fast (at least to a relative newbie used to uncontrolled airports). It is now about 4:30 in the afternoon and the airport was getting busy with incoming traffic. OK, I'll just wait. After the departing plane was gone, and another landed, and traffic was stacking up behind me, I was cleared for takeoff! Cool, finally out of here... except as soon as I started my takeoff run, the oil check door started flapping in the breeze pretty violently! ****, I got on the radio and told them I had an issue and exited the runway at the first exit. Handed off to ground for coordination. Now, I'm a gnat on a huge piece of asphalt with big boys all around and no idea where I am or where to go... Got out of the plane (copilot holding the brakes), got the door closed up, got back in line worried about getting blown into next week by someone's exhaust blast, finally make it back to the hold short line. This time, the clearance was "cleared for takeoff, no delay". OK, you don't have to tell me twice; it was pretty much full throttle from the line and off as soon as I could get the thing in the air. At about 200' AGL on runway 10L I was instructed to "turn left to 010"... in other words, "get lost dude!"

Stressful, but I've never left the door open again!

Descending Curves, a Hat Sighting, Gas and a Stearman 

Flew over to Bridgeport for gas Wednesday ($3.40).  Light wind from the N so a tight constant-curve (hopefully) descending turn to a ten foot square centered on the numbers.  Drawn to that curve and the last 20 seconds or so of a landing.  All nine brain cells humming away and focused as I can make it.  Really, really enjoy that feeling.  No wind makes it that much more enjoyable.  Never perfect - always trying to improve.  I think I would have liked landing on a carrier.  In the daytime...

'42 Stearman at the pump so a pic and some gas.  Passed said Stearman on the way back to 52F, overhead for RWY 35 and another stab at a nice curve with minimal landing distance.  The ground track shows room for improvement, but I did make the Charlie turnoff.  Scratches the right itch...for a day or so.

Touch & Go - LaGuardia, JFK, Teterboro, Newark Liberty, and Hudson River Corridor 05/02/2020

(Tim's RV-10 Blog)
With Sun N Fun cancelled and Oshkosh not happening this year I figured it was time to make use of the Covid 19 pandemic and capitalize on some airspace that would typically not be available for pattern work. Without a destination to land and stay at, what better place to go than New York!

For those unfamiliar (as I was previously) with the airspace in and around NYC there is a 20 minute ALC-79: New York City Special Flight Rules Area (SFRA) course the FAA requires that you take prior to entering the area. The course is well put together and was created after a 2009 mid-air between a Eurocopter and a PA32R-300. The course is very informative and a worth while use of your time. The FAA also supplies a kneeboard printout to help identify the mandatory reporting points for those interested in flying the New York Class B Airspace Hudson River Exclusion Special Flight Rules Area (SFRA). This corridor is where you will be flying if you want to circle the Statue of Liberty.   continue


Malformed nose skin dimple update ...Jskyking

Repaired- carefully flattened dimple w/ DDRT2, drilled with #30 with a slight circular rotation of the drill bit to clean the slight crack, re-dimpled with #30 die, dropped in a #30 rivet...... drilled another #40 hole and dimpled equidistant to next rivet and put a #40 in the hole. I would have put another #40 equidistant on the other side of the repaired hole, but it fell on on a flute. Vans said I would be alright to not put any additional rivets in beside the affected mis- dimpled hole, but one or two rivets was very acceptable..... building on.


RV-3B Ground Shot ...rv3pilot


From the 'Dumbest...' Thread

A good while ago when they were still doing "position and hold" at class D towered airports, a friend of mine, Larry, was given such an instruction so he taxied onto a runway. Another airplane missed the turn off on his landing roll which meant he had to taxi all the way to the end of the runway and he wasn't being quick about it, so my friend sat there on the centerline in his Bonanza.

A student pilot in a C172 was on final. Remember Larry is holding on the runway. Paraphrasing the conversation here.

Tower: "Cessna XXX go around"
Cessna: "Cessna XXX going around"

Some time passes.

Tower: "Cessna XXX, GO AROUND"
Cessna: "Cessna XXX is going around"

A little more time.

Tower: "Cessna XXX, GO AROUND NOW, make right traffic"
Cessna: "Cessna XXX, I'm going around the right"

As Larry told the story, he was getting understandably nervous. He said he looks out and just about ground level the Cessna passes him on the right, re-aligns with the runway, and lands.


May/June 2020 FAA Safety Briefing


Flap Notch Size and PIREP (RV-4)....smokyray

I built and started flying my Four back when we had to shoo Dinosaurs off the taxiways to go fly. The RV4 plans (if you built yours)have a great description and drawing of the front seat back flap notch block the handle seats into when you lift it.
If the notches are small per the plans, I found that final approach speed faster than 60 Knots would "pop" it out of the second notch, hence retracting the flaps. Being an F16 Pilot, I'm good with it as it does essentially the same thing with hydraulic pressure.
I started experimenting with slower approach speeds which took practice with my Sterba "big bite" wood prop. I found that slowing to 65Knots (70mph) on downwind and trim almost full aft the RV4 would get into a "groove" where you control aimpoint with pitch and sink rate with power. At 60 Knots, power on and a fairly nose high approach the airplane would not float and you literally could fly it right to the ground, flaps fully extended.
The best part was my flaps stayed down and I could now quickly retract them for proper STOL quick stop technique. I also made a few small adjustments to my flap handle to keep it where I put it, mainly filing it with a more pronounced notch.

Fuse Outboard Rib Fluting? F-1018 ...bkmerrill RV-10

26-5 Step 1 calls for fluting the F-1015 ribs, which I did no problems. It does not call for fluting the F-1018 rib (next further aft outboard rib) to match the curve in the bottom skin holes. I am now clecoing on the bottom skin and finding the holes do not align. I can get the clecos in going one at a time, but the rib begins to pucker/flute itself. Anyone else have this issue? Should I just flute the rib flange? Only concern with doing so is shrinking the overall length causing a different issue. Before doing so wanted to check with the trusty VAF.  ...

Another RV grin ...Matt Ziemann RV-4

After almost 4 years I finally got to take my daughter up. We'd been taking it slow---me not pushing it. She likes to taxi with me and loves talking through her headset, but anytime I'd ask if she wanted to go up she demurred and said she'd do it when she turned 4 or 5. On Friday, after riding with me to get gas, she asked if we could "go up above the trees". It was one of those absolutely perfect days--late day sun, beautiful skies, calm air, and just happened to take off after two of her other favorite planes on the field: a yellow Piper Cub and a red Fokker biplane. It was right in that golden hour before sunset when the shadows are long and everything looks so sharp. On takeoff she said "this is fun!" Of course her first flight had to be on the grass runway, and on landing: "I loved that!"  Afterwards we got ice cream...and she asked to go again the next day. Another RV grin...


First Flight of another kind. ...ty1295

Today was the 2nd biggest day of my fairly new RV-9A. Approx 6 years ago I met my now wife. At almost the same time I purchased my RV-9A partially completed kit. As the airplane build progressed, so did our relationship. Back in Sept my airplane became airworthy, and somehow back in December I became Husband worthy.

After the first 40 hours, my now wife went from scared to fly, to asking to take a trip to Biloxi back in February, and then a few weeks ago waking up in the morning and telling me "I am going to get my pilot license"

Well today was her first official lesson. Thank you to my good friend and fellow RV Builder Dave.  ...

Rough-Trimmed the Canopy Fairing
After more than a little tweaking and alignment, I was more or less finally content with the position of the canopy, and re-clecoed the flange in place. Then I got out some Sharpies and started marking the fairing up. After erasing the marks (lacquer thinner, with the canopy off, of course) and redoing it I decided that it was time for cutting it out.

A die grinder and cutting disk sure use a lot of air, at least my Harbor Freight one does. With both the air compressor and the die grinder working, the noise level was significant. The day was nice and a neighbor abandoned her patio, so I reluctantly closed the garage door and did it without that open. Cutting disks, especially 4" ones, don't cut inside radii very well, at least with my current knowledge, so this is only a rough cut. Here's the fairing and flange. The flange is trimmed.  ...


Dumbest Mistakes in an Airplane ...thompsonbr87 entry

I know a guy who, not long after getting his private certificate, decided to take a girl for a $100 hamburger. After about an hour flight, they landed, and walked a half a mile or so to the restaurant just off the field. That particular spot is somewhat remote with no other option for miles and no crew car. The pilot didn't realize his mistake until they were met at the door by a sign saying "Closed for the week".

Those two never went for another hamburger, $100 or otherwise.

Fun at the Hangar ...SeanB

I'll spare you the details of installing the Filtered Air Box on my RV7 this weekend. The best part was being joined by my wife, Tracey. She is so willing to learn and help, and projects such a postive attitude. Really cheers up the place while I may be trudging through a challenge. She also has a great sense of humor. Looked across the hangar and this is what I saw! I am blessed!!!


My RV Weekend

I flew to North Georgia to a private strip called Mountain Airpark. I met two three friends there. Here is a picture of our airplanes parked beside the runway.

As for me, I only worked on the airplane Saturday. After 228 hours, spread out over 118 work entries from 2/4/19 to 5/1/20, my baffles are finally complete. Not totally thrilled with the outcome - the front bottom inlet seals were troublesome and make fitting the bottom cowl a pain - but they are essentially complete.

Out fooling around Sunday evening. Dropped some flap and eased up in slow flight on some buddies in an S-7. Kirk whipped out his fancy new iPhone, and sent this later.

It's done with a photo-to-sketch app:

KORD Landing
Like AV8ER, this weekend I decided to capitalize on the reduced airline traffic to land my RV-7 at what is normally one of the busiest airports in the world!


5/5/84 ...non-RV. 

Met Susie Q thirty six years ago on this day back in 1984.  I had .5 in my student pilot logbook, Duran Duran hair, and didn't know what an RV was.  Nickel beer night at Graffiti's in Waco.  I asked her to dance.  She nicely said no.  I asked her roommate.  She nicely said no.  I asked Susie again.  Yes.

Married 30 years this June if I've done the math right.

Life lesson: Keep trying and never give up.  A good mindset for any year, especially this one.

PS:  I'm a 1-person small business fighting the good fight every day, delivering a good product for good people.  And I am grateful.  Up yours CV-19!  And the horse you rode in on!

I guess you heard by now OSH'20 is scrubbed.  DanH summed it up pretty well in a reply: "Last night I told the Fairy about the party being canceled. She bitched and cried and farted, then sulked off to get drunk."  Perfect. ;^)
  I started the 'What'd you do with your RV this weekend' thread a little late on Sunday, but Flying Canuck hit it out of the park almost immediately.  Beautiful pics (below). 
  I spent the weekend battling squirrels in the attic.  We've been hearing sounds for a few days, and a flashlight confirmed blurry brown movement.  Cage trap set with peanut butter sprinkled with cashews....
  Ended up catching (6).  Mom and five teenagers.  Relocated to a few dozen acres of woods around the lake miles away.  Two of them were caught at the same time, and they came out of the cage in nearly perfect formation.  #2 was a little sucked but he pulled it together at the top of the arch.  You gotta admire the focus.

The Amazing Shrinking Air Filters ...Carl Froehlich data point

For you RV-10 guys wanting a bigger filter, one option is to replace the standard filter with a taller one, the K&N E-1000. It is taller but same outside diameter.

You take the standard filter box and invert the top. Note the aluminum plate on the bottom of the box with the brackets. This was done to help prevent the filter from going conical.

This was for an RV-10 with a James Cowl and it worked very well. I assume it will work for a stock cowl but don't know.

Smoke Fun Video RV-4 ...Justin

The smoke system is new to me... Turns out I burn through it faster than I thought. I run out at the end.

The grass strip is Dad's place where I grew up and learned to fly. Still my favorite runway in the world.

And the underwing camera threaded into the tie down hole. The blue painters tape was just to prevent paint scratching. I've already had a few wise crack friends ask if it was structural...

I hope you enjoy!


Please Critique My Electrical Plan ...mfleming

A PDF of my electrical plan can be found here.

This is my first pass at the basic electrical architecture for my -7.
The mission is Day VFR, IFR, very little IMC, maybe pass through a marine layer.

This electrical schematic is a variation of one being developed on the Aeroelectric list.

This is a single battery, dual alternator system with a clearance delivery feature.

My version uses a B&C BC410-H 20A back up alternator with their back up regulator. The back up alternator also comes in on the battery side of the master contractor.

April 30, 2020.  Issue #5,073. 
First honest to goodness fuel run in waaaay too long in my RV Wednesday morning before the winds got too gusty.  And me being chicken prudent, I planned a flight going over nine private strips so I'd always have a landing strip on the nose.  There were a LOT of items taken off and put back on the plane during annual, and I like options. ;^)  Shockingly good resolution in the full size screen grab below.
  Experimented with the Carson Number setting that RV-6 driver Matt was talking to me about (links below), and hand flew (green line below) to $3.40 gas.  Working the list of things to address and enjoying life in the sky again.  Feels nice to fly.

My custom wood sides for throttle quadrant ...dwranda

Had to share my personal touch to the throttle quadrant I will be installing. It is Bolivian Rosewood which is quite heavy. I drilled out the backs to save some weight and am pretty happy with the result. Should look pretty sweet with my brown sheepskin seats and leather side walls. I even made a wood handle for the throttle lever to match.

Malformed nose skin dimple ...Jskyking

Was moving to fast this afternoon and the skin flexed as I set the dimple. Stupid mistake, setting dimples from the bottom didn't help, but the scratches should buff out caused by the die.
Anyhow, the hole is malformed and the dimple didn't fully form in the top left corner. When I dropped a rivet in the dimple, it's flush With the skin but there's a tiny space that the rivet head doesn't cover.
An Oops rivet would probably take care of the elongated hole but the rivet head wouldn't take up the small space on the skin.
I need to figure out a way to clean up the hole and reform the dimple.
To add insult to injury- it's a top skin.

I've talked to a friend who suggested the oops, but that was before I dropped a rivet in the dimple. Hopefully, there's a solution without having to replace the nose skin.  more


Air on Ground fail

I've read through several of the posts on this subject but didn't see anything that fixed the issue. Lots of great suggestions but thought I would reach out again to those that have gotten past this.

Everything on the ADS-B Performance report is fine except "Air on Ground", 3.76%

Trig TT-22 with Trig head mounted on panel (S/W updated)
GRT Safe Fly GPS
GRT Sport SX (does not control the transponder)

There aren't many option to change on the Trig that deal with GPS stall speed and too low of a stall speed other than the SQUAT switch question.

There are 4 choices

I have it set on NOT CONNECTED as I don't have a squat switch or airspeed switch.

If I switch it to AUTO ON GPS DATA is there a fixed speed the FAA uses to determine when to interpret ground operation vs airborne?

I have tried some of the tips and tricks such as hold a steady 3 degree glide slope and come to a complete stop on the runway. Then taxi slowly back to the hangar.

Any help or suggestions would be appreciated.



First Flights Reported on the Mothership


Leaving the oil filler cap "Open" to vent moisture ? (For a bit)

So I can't find any thoughts on an open oil filler cap to let engine moisture escape from a hot engine ??

So after a nice one hour plus flight today , after a fresh oil change, on a 300 hour well maintained engine (oil temp running at 185F). I pulled the aircraft is back in hanger .. I pulled the dip stick and again saw the milky white oily mixture on the filler cap / filler neck (clearly water in the oil) and watch the vapors pour out..

I'm sure it was a mixture of mostly water and maybe some hydrocarbons.. I then watched as the water continued to condense on a good sized and cold (35F) chunk of aluminum I held over the open oil filler neck. I mean a 1/4 - 1/2 teaspoon over a 10-15 minute period. (yes engine breather tube clear)

With the oil filler cap left on.. There is no way that 1/2 teaspoon of water is ever going to get out of the engine .. A 2' long 3/8ID crankcase vent tube.. that's open ONLY BELOW the engine.. sure is not going to let the moisture escape..

It really made it clear why these aircraft engines rust for the inside out.. A sealed up engine has no chance for a reasonable life unless its flown A LOT.

So can it be as simple as leaving the oil filler cap off for a few hours... to a day.. Letting the moisture "Vent out of the TOP of the engine... ? Enhancing the moisture dissipation by leaving the engine heater on for a few hours ( Cylinder & oil pan heaters) Yes.. There is no way you would want to leave an engine heater on with a "Sealed-Up" engine.. The moisture just able to circulate inside the crank case. Rust.. Rust ..Rust...

So there is a nice $49 monitor module (amazon) that will record temp/humidly every minute for up to 20 days and then be downloadable to a smart phone or Excel .. With a slight mod.. and remote wiring of the sensor, so I can have the sensor in the crankcase after a flight.. I'm going to get some real data on this idea ..

Anyone else looked into the simple moisture venting concept?

Experiment #1

Nice flight.. Let cool over night ..

Next day.. Measure internal engine humidity for several days

Experiment #2

Nice flight.. Leave oil cap off.. With engine heat for 6 Hours.. Heat off.. Cap off..

Next day(1) .. Replace oil cap.

Next day(2) ..Measure internal engine humidity for several days

Give me a 2 weeks and I will have some real data

First Flight: N87PR ...bhester post for Doug Rohrer

Today I flew over to Bowling Green, KY to do the first flight of N87PR. My buddy Doug Rohrer built this RV9A and wanted me to do the first flight for him, because it's been a while since he has flown. I went over a few weeks ago and did the inspection before the DAR inspection. The DAR signed it off Friday and the weather wasn't very good over the weekend but today was perfect. Only thing that didn't work was the airspeed, that wasn't a problem for me, but would have been for Doug and that's why he wanted me to do it, I landed it perfectly by feel. Congratulation Doug, she fly's fine.  more / pics


Milestone: 1st Engine Run! ...Juliano Selvatici

On Saturday was the day to do the 1st Engine Run. Lots of good vibes about the plane.  Everything went well. I was just a little nervous, but is part of the process, right?


Unexplained extremely high #4 CHT event ...scottmillhouse

First stock RV-7A with new Lycoming IO-360, Hartzell CS prop, 60 hours time since new. For first few hours I had high CHT across the board. Eventually traced to one of the new mags timing drifting over first few hours. Stopped at about 10 hours and has not drifted at least at last check about 10 hours ago.

Yesterday a typical flight only difference at landing with power pulled the engine appeared to be miss firing. Slight noise but could feel the exhaust misfiring pulses under my feet. Upon taxi from Savvy analysis of Dynon data showed 1000-1400rpm with #4 climbed over 2 minutes from 325-480. No evidence of any blockage. Initially assumed a malfunctioning CHT. Upon startup and taxi temperature was about 400 for #4, run up normal, back taxi about 20 knots did not cool but stayed about 400. Did another runup and #4 immediately climbed in 15 seconds to over 500 before I shut down. Audible misfire noise at shutdown and high temperature smell. For all events EGT stayed in line with other cylinders with no other parameters out of line. Shutdown runway for a few minutes to cool. Challenging IO hot start but then taxi to FBO temperatures stayed in safe zone. Let cool a half hour with another challenging hot start but they otherwise normal to circle and climb high just in case before heading home. Being late I just hangared it.

I plan to pull cowl and check timing, compression, remove and clean all fuel filters and flush fuel injection. Any ideas from the brain bank on what happened and what to look for?


Lycoming engines - limited time opportunity for quick delivery ...mothership Greg

This almost never happens, and wanted to make sure everyone had a chance to be aware...

Lycoming has opened up limited capacity to build some fast-delivery experimental engines for delivery in the June/July timeframe. This opportunity is for standard experimental engines only - Thunderbolt engines are not available on this special schedule. Please reach out to Chris at Lycoming - his contact info available at the link - to see if the engine you need can be scheduled. Note that the specific engine you need and parts availability etc. will determine whether you can grab one of their fast-delivery slots. Once you have arranged things with Chris, you can place your engine or engine+prop order with Van's and get things moving. Availability of slots is limited, so don't delay.


Status Report ...David Paule -3B

Canopy Flange Formed
The canopy got re-taped for the second flange attempt and after buying more materials, I succeeded in laying up the canopy flange. This time I used 3" fiberglass tape and 4" peel ply tape. It turned out that the epoxy remains was just enough to do this task and I didn't need to open the second can of the Rhino (or Jeffco) epoxy after all. Yet.

Here's the flange with the external peel ply pulled off. There's a bottom layer of peel ply that'll come off when I remove the flange from the fairing and canopy.

Some work is remaining, such as trimming the edges and probably some other things that I don't know about yet.


Quality Time Off The Surface.  Yay!

The RV-6 is back in the air!  A few laps around the pattern Tuesday to watch the temps - all good.  A couple of items to figure out, but it's good to be in the air at RV speed again.  Really missed it.  On with the tweaking and fiddling...

ADS-B OUT worked right out of the box (below).  Yesssssssss!!!! (strikes Napolian Dynamite pose).


My RV-7A gets BIG performance upgrade ...jhiggins

My RV-7A just got a BIG performance update, and so I thought I would pass along some of my experience with that. I've owned 3 RVs in the last 14 years, but I've never built anything. I don't really consider myself a builder, but more of a tinkerer. A year ago or so I decided I wanted a kick-*** RV that I can keep for a long time. I really prefer side by side, so that eliminated owning a Rocket. I wasn't really seeing anything for sale for quite a while that fit my needs, so I decided to buy something knowing I was going to do an engine/prop switch. I found a really nicely built RV-7A with an o-320 and metal fixed prop. I decided on the Thunderbolt IO-390 with a Hartzell Composite constant speed prop. Looks really nice under the cowl with the red engine paint and chrome rocker covers, and chrome battery box. My original plan was to hire out this work, but that wasn't really working out very well. I had some spare time and decided to just do the work myself. It ended up being approx. 250 hrs work in all. I replaced EVERYTHING firewall forward, including a new cowl (horizontal induction), and even the engine mount.

A few of the options I chose are: Earth-x battery, to save 10 lbs off the firewall. One regular mag and one Surefly. Vetterman exhaust, Avstar fuel injection, Plane Power alternator. The Avstar was chosen mainly to have a straightforward install of the snorkel. And it was, just bolted up nicely with no modification. I used the RV-10 oil cooler and firewall mount (with 4" scat tube), and I ended up using the RV-14 baffle kit. The baffle kit was really nicely put together, however I had to trim about an inch of height off the top of the metal baffles to fit the RV-7A cowl.

The plane ended up going from 1078 empty to 1116 empty for a 38 lb gain. Weight and balance is good as I didn't end up coming even close to the max nose weight recommended by Vans (in all weight conditions) and I also can load it up with a fat co -pilot and 100 lbs baggage and not exceed the rear CG. I plan on putting my smoke tank back in the back in the future anyway (20 lbs) and this will help a little with the nose weight.

I have flown off the 5 hrs phase 1 and everything is great! All temps are cool, especially the cylinder temps. Performance is outstanding. Acceleration on the runway feels more like a sports car than an airplane. True airspeed seen so far is 179 kts, 75% power. I hope maybe to gain a knot or two as the engine gets more broken in and I wax her up real good . The best I can calculate I am getting at least the advertised climb of Vans 200 h.p. website numbers.

Thanks to some buddies that helped: Brad Striplin, Mike Quinn, and Tom Rood. I don't think I would have attempted without some knowledgeable help around.


Elevators not even ...Tbarsic RV-10

I purchased a finished empennage and I am still checking to make sure things were completed correctly.

One questions, I have the elevators bolted together through the elevator horn hole where the push rod is bolted to. I checked and noticed the elevators are not perfectly even. Is this common, should it be corrected, is there a limit?

The horizontal stab is bolted to a bench.  more

PnP Mission - Flight to Freedom ...Danny Landry RV-7

Getting antsy with the stay at home order, I decided to fly another Pilots n Paws mission.


Trip Report ...Rich Macrafic 7A

Just getting around to compiling statistics of Cindy's and my flight to the Daytona 500 race in Florida in February in our homebuilt. What an awesome experience and an awesome plane!!

- Distance - 2258, or 2598 statute (road) miles
- Hours (round trip) - 16.9 flying, 18.2 engine running
- Fuel - 135.7 gallons
- Actual Instrument Time - 13 hours
- Approaches - 5 (2 ILS and 3 RNAV GPS), and one STAR
(first ever STAR for us; caught us by surprise!)
- Oil used -1qt.
- Avg speed - 133 nm/hr (153 mph). Note: All of the trip with
the engine dialed back to lean-of-peak (fuel savings more
important than speed).
- Top speed - 226 nm/hr (yes, we are a member of the 200
knot club, with the help of 40+ knots of tailwind!). That is
equivalent to 260 mph car speed (statute).
- Average fuel consumption - 16.6 nm/gal total (start &
warmup, taxi, runup, flying) = 19.1 mpg.

Kudos to the folks at the following FBOs for making this a very special and gratifying trip:
- Airgate Aviation in New Smyrna Beach
- Aircraft Specialists Jet Center at Gwinnett County Airport at
Lawrenceville, GA
- Hoosier Aviation in Terre Haute, IN

Also Kudos to the following people for their significant contributions to the success of this trip:
- Our A&P, for his significant help in finishing this homebuilt aircraft (especially the engine work) and his continued conditional inspections on an annual basis. His work gave us the confidence in the aircraft to attempt such a trip.
- My wife, sometimes pilot, sometimes navigator, always a 2nd source of expertise (trust, but verify), for her crew resource management. She caught a couple of things when I was flying (We really don't need to count them, do we?). We spent a LOT of time together in a VERY SMALL space! I could not do that with just anybody!

Flew New to me RV-9 home 2600 miles! ...Ed Lee

Left Yakima Friday morning with my new to me RV-9A. I had 20 minutes in it before leaving. Great airplane. WX over the Rockies not good enough to fly direct so I went down the west side of the Cascades through Salt Lake, then finally Moriarty, NM just east of Albuquerque. Crashed for the night and off across the high desert and stopped finally at SC76, home grass field in Lancaster, SC. Had at times 236 mph over the ground south of Memphis getting the push from the low to the north. I flew most of the trip at 12,500 ft, but had to go to 13,500 to get over some build ups flying over the top of the Altanta Class B. I have never had such a great xcountry airplane as this, IO-320, 160 hp, Still climbs at 500 fpm at 13000'. Amazing. I averaged just under 8 gph at 190mph true airspeed at 12,500. I have helped build at RV-7, helped build a Sonex-Onex and did build a Sonex-Sonex/Covair which has flown to OSH from here three times. It is tight and very altitude limited but it is fun.

The RV-9A is simply astounding, I hate I didn't build it, but I am 76 now and question building vs flying for what years I have left.


Phase One Panel Love Almost Complete

Updated G3X screens in Flash from Gen 1's to G3X Touch, updated the audio panel to a GMA245 (BT to phone yay!) and the GTX330 transponder has been sent in and upgraded to a GTX330ES (ADS-B OUT).  Years in the making! ;^)  AeroLED strobes installed after a couple years sitting on the shelf (all my fault).  Ran the engine Monday and got a look at the oil pressure/temps, does the radio work, does the audio panel work, etc.  Need to address a couple of config error CAS messages that came up, but getting close to flight.  Really taking my time with this, as a LOT of wires were removed/moved/re-installed.  Looking forward to peeling off that plastic from the screens and returning to RV skies. 

Click to enlarge to 3,840 x 2,588

Fresh annual.  Prop governor checked on the bench at prop shop.  P-mags removed, bearings inspected, re-installed and timed.  New tires.  New bearings in tailwheel.  Lots of other love.  Almost ready for summer.

Phase Two/Beyond:  ADS-B IN, an autopilot control panel and swapping out the 2nd radio for a remote unit that talks to the touch screens - 2nd radio will become the primary radio down the road.  Baby steps...

On the Lookout For:  The nerd in me wants the right landing light to blink 'D' in Morse code (-..) then the left to blink 'R' (.-.).  Come on technology - you gave us a high end toilet with 38 buttons.  This should be easy <g>.

N8PH first flight ...Carl Froehlich

A year behind schedule (2019 had many challenges) but N8PH jumped off the runway on April 7th. She flew strong and straight. Wheel pants to go on after a few more hours to make sure I'm happy with the gear. Paint to happen in the fall as I have a lot of flying to catch up on this summer.

A month of rigging and extra eyes paid off. She flies hands off, wings level and ball in the center.

The only two issues are the horrible weather conditions keeping me on the ground, and my amazingly rusty landing ability.

Keep building and fly your own rocket ship. It is well worth the effort.


Has anyone else experienced this? ...Jim Harris RV-7A

Finishing up my annual condition inspection and the A&P and I were checking connections and nuts on FWF. Everything was tight and secure except when we got to the fuel injector throttle body. Only one of the four nuts securing it to the engine was tight. Two were so loose you could spin them with your fingers and one was totally gone. The engine still ran smoothly.

Replaced all star lock washers, replaced the missing nut and tightened all to torque. We then added four nylon end nuts on top of the existing nuts and secured them - there was just enough room on the studs.

My A&P said this was the first time he's ever seen nuts loosened like this - especially if no one's worked on the item. He distinctly remembers checking the throttle body last year and every thing appeared secure then.

Our question: My engine is the Superior XP IO-360 B1AA2, has anyone else found they've had to tighten these nuts due to them becoming loose? This could have really ruined my day later this year if not discovered!

15.9 Flight Hours - Now a Few Questions ...azflyer21 -14A

I'm flying in the Phoenix area and have about 16 hours on my 14A, here's a few questions:

What should my Oil Temps be reading? (Aeroshell Mineral 100)
-Normally 212-215 OAT 60-68
-Today 238 OAT 75

Full Flap Landings require what seems to be a large amount of nose-up trim, is this normal?

I am planning first oil change at 25 hours, is this about right?


DIY Center Consoles

(Paul_5r4) Thanks to CV-19, I haven't worked since the 24th of March. I could get use to this! Trying to use my time wisely so I recently completed the 8th annual condition inspection on the RV. It was due this month anyway. Once I finished, I thought I would pick up on the original posters nice looking center console. I did change mine up a bit. I have an arm rest in the forward area between the seats which I love. Little spot below for pencils and paper. I wanted to use the more aft space between the seats and the space moving up. I have the manual aileron trim just aft of the armrest so can't cover/interfere with that area. I still have to put some kind of stain/varnish/paint covering. It's secured through the bottom with a single screw through to a nutplate on the bottom side of the tunnel cover. I also have to come up with a simple latch at the top. Test flew with in tonight. Can't even tell it's there. Here's the finished project. I like it. (I meant to weigh it before I left the airport. I'll be surprised if it weighs over a pound).  ...

Also has a large (3-1/4" W x 8" L x 5" D) opening for whatever else I might need.

Here's a couple of pictures. I'm pretty happy with how it turned out. Downside of using plywood is a few cosmetic chips, but most of those won't be visible once this is installed.


No, I was not shot down! ...bhester

Friday after work, it was just too nice not to go flying. I was just out flying around when I noticed on my screen that my buddy David Adams was up also not far from me and near his house. I flew toward him and we spotted each other, we were pretty much over his house so we decided to do a fly by and his wife was in the yard. She ran into the house and got her camera because she knew we would most likely be coming back around. Even though this was not planned and she didn't have anytime to setup her camera, she got a few good pictures. David sent me a quick shot of a picture of me from her computer screen. It looked pretty good and I asked him if he could send me the actual picture so I could use it as my desktop picture. He said no problem and when he sent it, of course this is what he sent me, funny guy!  ...


Not happy with these rivets... ...Eztroller

Page 25-04, step 4 says to rivet the bearing bracket assembly to the rib using AN4264-8 rivets. I used a rivet squeezer to complete this task, and as you can see, it did not turn out well. Some of the rivets swelled between the rib and bearing assembly so the material is not lying flush/smooth. Also, the shop ends of the rivets appeared to have deformed the rib enough that it is visible with the naked eye.

I am ordering new parts, but wanted to see if there was something I am missing here. I am contemplating back riveting next time and possibly using a shorter rivet, but any help would be greatly appreciated.

Side note, I stopped by the factory yesterday and was able to get the parts I ordered in a very short amount of time. They are following all of the CDC guidelines and left my items outside in a bag with my name on it. Great people this community has working for us.



Water in my elevator ...DylanRush

Hi friends,

I just bought an RV-6a last weekend. I will keep it outside, as the hangar costs are so high in my area (Seattle) that I could just buy a new plane every ten years rather than store it inside. Not to mention hangar wait lists are 2-4 years long.

This week I noticed after some rain, water is collecting in the elevator. The side with the trim tab seems to drain but the side without the tab does not.

I'm wondering if I can drill a drain hole, and if so where.

Also what kind of resin or epoxy can I use to fill out some minor cracks in my fiberglass? And is it realistic for someone with an electronics and engineering background to be able to install some new avionics even though I haven't done much work on cars or planes before?


My RV Weekend ...airguy starts it this time

Qualified for the "Iron-butt" award on Friday.

I had a bit of a cross-country that needed to happen, my uncles 172 needed to be transported down to Jesse Saint's place for a new Dynon panel install. Friday was the day for good VFR all the way (or mostly good, as it turned out) so we saddled up and pushed. He took off about 6:45 am from our west Texas private strip and headed east, and I took off about 8 am and caught up with him at his second fuel stop in Hammond Louisiana. I had a great tailwind at 17,000 on the way there. Notice fuel quantity and range to empty in this shot. Gotta love it.  ...

Formation Practice ...5min 49sec video.  dr

Sid organized a 6-ship practice at 52F.  I'm still reassembling the -6, so stood on the side with the iPhone and a tripod.  No talking, just RVs in slo-mo taking off and landing and a couple of passes.  40* crosswind from the left burbling over the hangars had 'um working it.  Editing on iMovie on the phone - quick and dirty.  Enjoy.


RV-6 Rebuild Update ...jamlip

Well the RV-4 sold today to the first viewer. I don't feel particularly happy about it - I love that aircraft. It was my gateway to aviation in the US and I have lots of happy memories attached to it. It was also mega to fly.

The buyer brought along Lars Pedersen, of this parish, for the pre-buy. Lars also looked around my 6, having seen in in the past when it was in pieces and had a cobweb for an electrical system. He seemed to like how it was coming along. I enjoyed seeing Lars' well-travelled RV-7, which is a lovely build and has some nice kit on it.

Anyway, now I need to turbo-on with the 6. No point owning an aircraft that doesn't function as a flying device.

The cowling is looking better. Like, stripped of paint, but at least the gaps are half decent now, and the front doesn't look like someone attacked it with a shotgun. I'm finding it easier to get the cowl on and off the aircraft, too - you just have to learn each aircraft's little 'dance routine' as David Howe put it whilst talking on the phone a few days ago. David has been a great counsellor for many parts of this job.  ...


Spark Plugs ...Scott Hersha

I need a spark plug with a shorter height from the cylinder to the top of the plug where the harness attaches. My RV4 doesn't have a whole lot of room (O-360-A1A). I just replaced all the baffle seals, as well as installing a new ignition harness, and there is very little clearance from the top of the harness where it attaches to the plug, and the cowling in the cheeked cowl. I've heard that Tempest plugs are a little shorter, but have been unable to get any external dimension details from either Champion or Tempest. I am currently running Champion REM40E's. They were new less than a year ago by the previous owner, and in checking the internal resistance, it ranges from 1300 to 2700 ohms. I've heard that Tempest UREM37BY's are not as tall. I'm not all that concerned about the slightly cooler plug (higher CHT) of the -37BY's. I'm not unhappy with the performance of the Champion -40E's, I'm just looking for more headroom. I haven't been able to find a reference for external spark plug dimensions. If anyone knows the external height dimension, from cylinder to spark plug harness connect, please let me know.


If I have to buy new plugs, I'll probably pick Tempest.

Milestone: Commercial Rating (checkride in the RV-6A)

Checkride this January out of KEHR. Stalls, emergency descents, engine out landings, soft field, short field. It was not easy but doable. The RV-6A wasn't the easiest to do the Lazy Eights or the Chandelles to spec. Definitely not a C172 in those areas. I had used the same DPE for my IFR checkride so he was comfortable doing the commercial in an RV. Thank you to Mr. Van for giving us a very capable airplane. The Corona Virus has put me in the holding pattern as far as my next step... The multi-engine commercial add on. With that said, does anyone have recommendations for a flight school for the multi engine add on? Thanks David


Another RV-6 Project ...UKFlyboy

I have recently taken over an RV6 part-completed project. Imported to the UK from the US, its an early kit from 1989, and comes with a fixed pitch 180 HO Lycoming.

Now started on fixing some build issues and moving on ASAP, the current Covid-19 lockdown is giving me time to work on the project.

Here is a picture of the airframe as it was towed to my hanger, you can see I've squeezed it in besides my Aeronca Chief, you can see the tips of the wing and tailplane in the pic, and the fluorescent lights are mounted on old HS frames from the Chief, they were too rusted to use but make great light holders. The wings are built as is the rudder and tailplane but there are issues with the build of of the stabilisers, so some rebuild will be required.


My Coronavirus Escape Day in a RV-7 ...Boyd Birchler

Yesterday morning I climbed into the left seat of Boyd's RV-7 as he waited quietly from the right seat. At that point, I'd already challenged him to a flight to circumnavigate our state, the state of Indiana, and he'd accepted with only one request - that we fly his RV-7. No problem. On the up-side, it's faster than my Decathlon, more fuel efficient, and lands, taxis and rides better on windy days. On the down-side, it has a brand new Garmin G3X full glass panel and the 'gauge-girl' in me is still trying to deny it's time to join the 21st century. But I'm ready to go and let's just say it wasn't going be the same relaxing flight as would have been in my own bird. Before climbing in, we'd already agreed to share PIC time just like we did in 2018 when we flew the perimeter of the U.S.  ...


The RV Grin ...Matt Ziemann pics

"I know from a photographer's perspective this isn't the best photo---too fast shutter freezes the prop vs getting a nice disk, exposure makes the whole plane look dark...but that covers up the fact that this picture captures the essence of the RV grin: a helluva fun tailwheel plane, pitching up off a grass strip on a beautiful day. My brother, rehacking his tailwheel and acro currency after 4 years, had the RV grin. And even though I wasn't flying, I had a pretty big grin, too---especially hearing my 3 year old daughter cheer him on with "Go Uncle Mike! Go Uncle Mike!"

Second picture is better from a photography perspective...but there's just something about the clouds and blue sky in the first one...and the dynamic nature of him pitching up."

  One odd stat during all this CV19 drama is that the VAF forums are busier than I've ever seen them.  When there would normally be 300 or so people in there in the morning around 0800, I'm now seeing upwards of 900 at times.  That hasn't kept a couple of advertisers from needing to bow out for awhile (completely understandable), but in the same breath a huge thank you to those who visit the site and the advertiser sites.  Weird times, and our family is in financial 'lean of peak' mode just like everyone else.  Hang tough and we'll push through it together as best we can.  Faith in humanity.

My RV Weekend ...crabandy

A quick trip to the lake to take care of some springtime chores. Yes, Pie is missing her front tooth....she was wiggling another lose one as we were loading up. Despite the look on Lil' Dude's face (more his fighting off a nap look) he loves riding in back, he even calls it ahead of time like "shotgun."


Life in the RV Lane

Re-assembly of the RV-6 continues.  Tuesday morning was to be a quick wheel pants on session, but ended up spending time, as is sometimes the case with aviation, finding tools to deal with setbacks.  A screw twisted in half (new screw, clean, lubricated and a nice bit on the hand screwdriver).  Weird.  That doesn't happen very often.

Where's the drill and bit?  Drill out the nutplate and find the squeezer, dies, cleco pliers, rivets and all the other stuff you need to drill out an old nutplane and install a new one.  This plane has been flying for nearly 18 years.  The tools are in drawers (I think).

It actually kinda felt nice to work with other-than-screwdriver honest to goodness airplane tools, if only for a bit.   Continuing tomorrow.


Placed Timing Mark on back of prop. ...gasman

I wanted to find a safe way to check the timing of my electronic ignition without being so close to the prop, and without the need for another person.

I made a bracket that would mount in the left inlet and allow an adjustable pointer to be mounted 3" from the back of the prop. I then set the timing that I wanted using the marks on the flywheel and a 32 oz yogurt container mounted to the nose cone with blue masking tape..... It had my cell phone mounted to it with blue masking tape also. With my Clinometer app, I had accuracy to within a 10th of a degree.

I then transferred the timing mark to the back of the prop and adjusted the pointer to alignment viewed from the pilots seat. I set the timing light in position close to the pointer secured to the top of the motor.

Waited till sunset, jumped in and fired it up..... perfect timing, with and without the vacuum line connected. So how accurate is it..... at that distance from the flywheel, 1/4 inch is one degree of movement.


Second Test Flight Some Bumps In The Road ...rolick22

My canoe gets a panel. ...rv6ehguy

Suddenly, I have a lot of time on my hands and I am making great progress on my RV6A project. My panel is finished. After many years of indecision, equipment changes, and improvements, I finally settled on this-Version 11. I used a program called XPanel to design it but that wasn't good enough for me. I wanted to see it and touch it. So I used plexiglass to mock up the panel. I did several changes on the plexi (cheaper than aluminum). I added all the equipment and when I was happy with what I was seeing and touching, I committed it to aluminum. And yes I actually did sit in the canoe to see how everything looked and to make sure I could reach all essentials. Ergonomics 101. The aluminum panel was hand cut. No CAD programs for me mainly because I don't know how to use them. I'm more of a hands on guy. I still have quite a bit of wiring to do. I just needed everything in place to make sure there was no interference issues. A few minor ones showed themselves but nothing I can't remedy. I'm very happy with the results. Now the next step is to gradually turn everything on individually and hope I don't see smoke. A special thanks goes to Danny at SteinAir who painted and laser engraved my panel. Did I mention that I spent months on selecting my colour. I've never looked at so many shades of grey.

Opinion on my canopy fairing please ...Reilly

Hi guys

My first fiberglass effort and not unhappy with it so far.

I would just like some opinions from the gurus on the area and gaps around the hinge bolt holes. I know its a less attractive part of the 12 but are mine too large or is this how it should be? I did take time to ensure that the bolt hole on the template was directly over the bolt.

Appreciate the feedback

"DR, quick note. A few days to the year, Dilemma flew again. In the spirit of the learning part of EXPERIMENTAL I decided to build my own engine and mount it on the RV. With help from Dayton Murdock and a visit from Paul Dye, the engine came along.

Plane did well. Better than I expected. Temps are running below what they were with the old 340 even during the break in. The 360 is bigger and caused all kinds of problems for installation.

Will start posting here and there of the process of getting Dilemma 3.0 back up."

Injuries While Building ....DanH's entry

I was working in front of a 6" wire wheel, on a stand mounted bench grinder. One single wire flew up and stuck itself squarely in the end of my nose, sticking straight out like an arrow. I felt the impact, then stood there for a moment, extremely cross-eyed, trying to determine what the blurry thing might be.

Good case for eye protection.

(BoilermakerRV's entry)
Safety Glasses Aren't Perfect.  I was using a combo belt/disc sander on a bench. I think I was cleaning up the end of a piece of angle that I had cut on the band saw. I swear I saw that chip the whole way, in slow motion. Off the sander, bouncing off the table, up UNDER my safety glasses and into my right eye.

Managed to drive myself to urgent care, where they flushed out my eye. Said they could see some scaring on my cornea, but have never had an issues with vision before or since.

Stay safe builders!


Fuel line. dented flare ...fazlo

Hello all,
While removing the right-hand side fuel tank on my RV4, I dented the flare of the fuel line. I cut and redid the flare but it's now just a bit tight and susceptible to chaffing near the grommet. The fuel line goes in one piece from the tank to the Andair fuel valve. Instead of redoing the whole line (which is a complicated 3D exercise!), I am thinking of cutting it behind the fuselage wall, add a replacement tube, flare and use an AN815 union. Is it acceptable or would you advise to redo the whole line?
Thank you very much

Fitting the Cowl - How good is good enough? ...UnPossible

Well, I've waited a few days, and the cowl fairy has not flown in to fit my cowl ... guess it's time to get busy.

I've spent a couple of hours trimming the cowl around the spinner area. It's getting closer, but it's not perfect.

Below are a couple of pics of my progress... It looks like in order to get a good circle behind the spinner, I will need to fill in a bit of the joggle on either side of the spinner.

I'm wondering how good is good enough here to drill the one hole on each side where the cowl halves overlap, and move forward to fitting it on the fuselage?

Mis-Aligned J- Channel / right wing ...Jskyking

I can see thru the dimple jchannel and out the top of the wing but it is too far out of alignment to fit a cleco.

I talked to Vans twice today, this morning they suggested to lightly bend the j-channel or as a last resort, take a dremel and remove a little of the material in the slot where the j- channel sits on the rib. ...

Aerobatic Fuel Tank ...NorthernRV4

Good day fellow RV'ers

This winter I've been building the starboard wing and I'm at the point of putting the finishing touches on the tank. Firstly, this tank is getting a flop tube and the standard Van's resistive fuel senders. I'm looking for some tips & advice specifically on mounting the sender in the second rib bay and the anti-hang up guide strap. Van's plans are pretty simplistic and don't show at all any dimensions for mounting the sender.

1. For the sender, do you mount it in a cover plate similar to the end rib to allow for greater access and ease the inserting of the sender/float arm? Or is a simple hole for the sender sufficient?

2. At what vertical position would the sender be mounted in the rear baffle? I would think roughly the same position as mounting it in the end rib would put it.

3. Do you bend the rod to the same dimensions as if it was mounted in the rib? I'd rather not have the tank all sealed up only to find the fuel gauge is way off. I expect some inaccuracy but I'd like it to be as close as possible.

and lastly, in regards to the strap. Did you just fabricate a guide that looks like the diagram provided in the plans? Any specifics here to consider?

Thanks in advance, keep calm and build on!

Rigid Fuel Lines ...efitzgerald

I am working on my firewall layout and started on the fuel lines. I am using a SDS fuel injection system with their case mounted fuel block. I had originally planned on using flex hose in fire sleeve from the firewall to the fuel block. I saw another members post with a similar install and he had used hard lines from the back of the engine near to the fuel block and it looked like a great idea.

In my picture the lines are aluminum for the purpose of mock-up only. I was going to have TS Flightlines make the stainless lines. The lines would be flared on each end with aluminum AN nuts. There would be a bracket bolted on top of the fuel pump block off plate to secure the end of the rigid line where the flexible hose connects to it with steel AN fittings. I planned 1 to 2 brackets bolted onto the engine to support the lines.

Is it a mistake to do it this way?


The Restorative Power of Flight

I went out to the airport Wednesday morning with the best of RV intentions.  But having passed a few motionless flags on the way, and seeing 00000KT on the phone when I looked, that plan went out the window.  The RV isn't buttoned back up, but the Cub is, and it has been a few weeks since it has been off the surface.

The stock ponds were mirrors and dew covered bright green fields fighting for spring sunlight exploded in the morning light out to the horizon.  Almost fluorescent.  What you don't realize about 52F is that five minutes to the NW in a Cub at 100' AGL over farmland, you could pretty easily convince yourself it was 1946.  No houses, just creeks and farmland.  A little inattention and the ball is out again - stick and rudder skills matter with this one.  The joys of simple, uncomplicated flight with no radio - there's only one knob (baro) and one switch (mag).  You don't really need the baro.  The checklist is short.

After .6 of restorative therapy, I taxied up to the hangar and began planning the morning's original task of putting back on access covers, fairings, cowlings and wheel pants on the amazing RV-6.  An RV is the polar opposite of a Cub.  It so beautifully masters fast and high and acro and technology, and rewards well practiced skill sets.  I miss going fast, and need to get that thing put back together this week, but 00000KT demands Cub if you have access to one, and plodding along at 40mph in ground effect a foot or so above the growing wheat touches the soul in a way that few things can.  If you've never done this you'll just have to trust me.  A Cub-shaped shadow on a field of blurred, wet green in red-shifted morning light can set things right in your head.  Email and accounting software are easier to face with recent memories like these.

Fourteen deer and three turkeys in the memo line.

Same plane in 2017.  dr  pic.

But even the new plan didn't go as expected.  I sat on the couch jotting down a few thoughts for this piece here, with the clicking and ticking of the 65 h.p. engine cooling down in front of me, and my train of thought kept getting distracted by all the RV activity.  It turns out RVators like 00000KT too.  There's Allen in his -14 taking off.  Now Danny in his -8, and Ross in his -6.  And Matt (-6), and John (-8), and Kay (-8A), and Randy (-8) and James (-4) and Rod (-8).  They too saw the windsock, and changed their plans to take advantage of the CAVU with their own RV version of social distancing.  I'd guess they didn't see the turkeys.

What a Blessing it is to get to enjoy these.  High and fast in the amazing RV, and low and slow in a worn, tattered, dusty, dripping J-3 that reminds me of both simpler times and why I'm also attracted to this different type of flying.  These two aircraft, and their wildly different flight envelopes, realign my mental gyros like nothing else.  Blessed and Grateful are the words that keep coming to the front.

I'll get the RV in the air here in a few days, but I'm glad the plan changed on the fly.  Formation practice is calling me and that is all RV.  But lazily exploring a creek for fish and beavers from a hundred feet will be up front here again before too long.  Anyone standing outside around N. TX Wednesday would understand.  Aviators get all goofy-eyed when the METARs are all zeros.

It's our catnip.

We are beautifully flawed.

Unfortunately, as we're all aware, businesses remain shut down, which precludes meeting anywhere out and about for lunch. There is the option of meeting elsewhere, and I know I'd talked about hosting at my hangar in April, but both Josie and I have been sick in the past few weeks, and I don't think it's wise right now.

Long story short, I'm not going to plan on a monthly lunch for April either. With any luck, next month we'll be on the other side of this thing and we can get together again - and I intend to follow through on hosting when that time comes.

Thanks for continued interest and attendance; we'll get this thing going again soon.

My RV Weekend ...Jpm757

Took a quick trip down the Hudson River VFR corridor. Usually loaded with traffic, I didn't see one other aircraft. One circle around the Statue of Liberty.


Reassembly of 'Flash' Continues

Slowly putting things back together after (because of me and a perfect storm of schedule chaos) the longest annual in history.  New upgraded avionics stuff to show off soon (as it goes in) and slowly making progress in a weird world.  Baby steps.  All the screws were in a cup and covered in oil, so I sprayed them with LPS-3 and got out the towels.  Let the sorting begin. 

James was kidding me about just going ahead and using new screws.  He obviously doesn't know my routine.  There is easily another decade in most of these screws.

Save those pennies, baby! ;^)


Post Trip Report ...kaweeka RV-9A

My 3 month sabbatical turned in to a brief 3 week flight from Sacramento, Ca to Guadeloupe then back after Covid 19 showed up. It's amazing how fast everything spiraled down the drain. We spent 4 days in Antigua then flew 52 miles to Guadeloupe to find the entire island shut down. At that point we figured we better get back to the US before everything closes everywhere.

All in all the experience was great. The plane flew flawlessly. About 7,500 miles in all. After I got back, the world changed (in just a few weeks). I'm back seeing patients on a limited basis and volunteering to work the in the ICU. It's been a few years since I had to manage a vent but it's amazing how fast that knowledge comes back.

There are a few things I noticed, however.
1) I need to change the front crankshaft seal. Watched videos and read a lot. Seems pretty straight forward. I ordered 2 seals just in case I muck up one! Saw a tool I can make and spoke to one fellow who uses bicycle tire plastic irons.
2) I was supposed to stop at AFP for some individual tuning with Don but for obvious reasons, could not. When this mess is over I would love to get with someone closer to Northern California who knows the system and would spend some time on this. The plane runs great but I think we can get better and the experience is invaluable.

Please, everyone, heed the social distancing. Be safe. I see this up close and personal. I hate to think anyone got sick who could have avoided it. Happy Easter,


Day One ...David's RV-10

And the adventure begins.....   What a difference an hour and a half can make ;^).


Status Update ...rmartingt

So the engine is more or less built, minus a couple of accessories. Slightly older picture.  I've decided to start fitting the baffles (at least to the engine, I know I can't trim the cowl side yet and they need to be off for cowl fitting) while access is easy, and started on some of the accessory work while I get the shop cleaned up. I'll probably go ahead and paint/assemble them (again while access is easy) and that way I can fit them quickly later. It's also just nice to be working with sheetmetal again for a bit.  ...


Teach me how to CAMP out of the RV. ...roofus4

I am taking the month of May off. I want to do a long trip in the RV, but in this time of Covid19, I'm worried about where to stay and whether any hotels or lodges would even be open. Camping comes to mind.

I've never considered it before now. I would be starting from scratch. I have absolutely nothing in regards to camping. I need ideas for everything! Tents, sleeping equipment, how to eat, how to pack it in the RV, and even suggestions on things like camping etiquette.

Then where to go? I live in TX. I'm thinking Idaho, Washington, or Oregon.

I know I'm asking a lot of questions, but thanks for your suggestions.


My RV Weekend ...goatflieg

Back to baffle work. Who knew that the air seal fabric would take so long to fabricate? I didn't... but I'm learning. Not done yet... but progress is progress.


$100 Burger ...leok

The wife and I flew from Pontiac, MI (KPTK) to Owasso, MI (KRNP) for fuel ($4.18) best price around. There is a very small diner on the field that is open for take out. Two burgers and chips ordered by the wife while I filled up the plane. We ate in the completely empty terminal building as it was too cold outside, washed up, sterilized with sanitizer and flew home.

Pontiac cleared us to land 6 miles out. During normal times there might be as many as 6 planes doing training in the pattern. I have had to remind tower to clear me for landing while turning final.

A weird world we live in now.



April 14, 2020.  Issue #5,061.
  The first construction picture.  My buddy David's RV-10 empcone kit is scheduled to arrive at his house on Tuesday the 14th.  We were texting back and forth a little on Monday, and I typed something to the effect of, "Make sure you take a picture of the kit before you open it - you'll look back on that and smile in a decade or so."  And of course that got me to thinking about my own family's RV-6 and when the tail kit arrived in late December of 1996.  Here is Audrey, who had recently worked out the skill of walking, taking a stroll around the tail kit of N617AR (her initials).  She was probably thinking about chemistry...
  And that got me thinking about the builder log, which was sheets of paper 3-hole punched in a notebook.  It worked swimmingly, never needed updating and was 'backed up' with a camera.  The top of page one is below.  I spent 15 minutes opening the little box holding a camcorder, and it still makes me grin when I think of what was inside - particle board for making the alignment jigs for the HS, VS, rudder and elevators.  The first box I opened of my someday-flying aluminum airplane was full of wood. ;^)
  I hope David takes that picture.  I took mine 8,503 days ago, and it still brings me joy.

RV-6 Rebuild Project (and some RV-4 thrown in there) ...jamlip

A while back, whilst trying to decide what coms to put in this thing, I found a local ad from a guy selling basic 2.25" mount radios for a few hundred dollars a pop. His name was Frank, and he had a stock of 25kHz-spaced stuff which he was getting from Germany after Europe went to 8.33kHz spacing. I figured one of these would suffice until I'd flown the aircraft enough to decide whether I wanted to keep it or otherwise.

Frank sorted me out with a Becker unit, which I wired to a Signtronics intercom which I had laying around. I couldn't get sound to come out, so, suspecting the intercom was duff, I changed the intercom to another Sigtronics box, but the improvement was marginal. I wasted a lot of time trying to get it to work, and didn't really learn much in the process.  ...


I'm Doomed

I just ordered the empennage kit. It's an RV-14A. Go ahead and mock me. Tail draggers are infinitely cooler. I'm not cool.

Spending so much time at home means I'm spending way too much time thinking about building an airplane. I also realized that Van's is going to start charging sales tax on shipments to NC starting in May. I needed to get the order in to save some money and give me something to do at home other than argue with the family. ;-)

Wish me luck.

Tailwheel MX Video ...Blake Frazier

For those of us that aren't familiar with tailwheel maintenance or have been putting off maintenance for fear of disassembly, I put together a short video discussing the inner workings of this mechanism.

I've got a longer video in the works dealing with troubleshooting common issues that we see in this mechanism, but it's not ready quite yet.

If you're having issues or need advice with a tailwheel assembly, don't hesitate to get in touch with us... we're here to help!

Put that 3D printer in your airplane shop to good use for medical personnel ...Mothership Greg

A little off topic possibly, but we can put our aviation design tools to good use right now, so I think it's worth the post.

Some of us have 3D printers available to us - or even sitting idle in our shops. If yours is sitting idle right now, consider this a challenge to go grab this simple printable project and make surgical mask straps for your local hospital personnel. These 3D printed ear guards help relieve some of the discomfort that wearing face masks all day can cause.

This idea comes via Hudson Wiliams, a young man in Alabama who's making them in his hometown for people working the hospitals there - including his mom. He's recruited some friends to print them as well. If he joins VAF (and he should, since he just finished building a Van's sign kit and will one day - I'm pretty confident - build an RV), then hopefully he will chime in and maybe add a photo/thought or two.

We can pile onto his idea here, and help spread even more of the good.

You should be able to print several of these at a time on a typical home 3D printer! Drop them off for your local hospital.


Extended go pro mount ...Simon Hitchen

If you're looking for a little quarantine project....

I Wanted a better perspective for inflight photos so I made this mount to extend ahead of the wing by 2 feet. Makes a real difference.

I used 3/4" carbon fibre tubing with 3/4" aluminium square stock (all provided by my hangar mate John). I fabricated the brackets to fit into existing holes/nut plates for the wing tip attach points.

I was worried about vibration but it turned out great.

First photo is of the mount without the camera on the end. Second is a photo with the go pro mounted on top of the wing (old position). The third photo is with the camera mounted on the new carbon fibre extension rod. Much better photo.


My RV Weekend ...various

(SPX)  The weather in San Diego finally cleared today, so I woke up early and took the RV up for a flight.

I really had nowhere to go, so I decided to fly along the coast, down to Coronado, and then reverse course and head back to Fallbrook to do a few landing before putting the airplane back in the hangar.

A short video out the side window as I did the 180* turn..

Interesting flying right now .. SoCal approach had one controller for the entire San Diego area. I know that the facility has limited staffing now due to less traffic, and also to help reduce the chances of a controller getting COVID-19, and getting the entire shift sick. So, they've reduced the shift size so as to have a backup team if one shift gets sick.

This was likely to be my second to last flight before converting the panel from this to this:


Milestone: First Start ...Joe in Longview, TX

Ran my IO-390 today for the first time! Started on the 3rd blade. However it was not without problems.

1. Ran very, very rich. Had to lean the mixture a lot just to get it to idle. Was able to richen the mixture as RPM's increased but had to lean it again once I began reducing the throttle. Does anyone have the procedure for adjusting the injector mixture?

2. Hartzel prop would not cycle. I think I ran the engine long enough to fill the prop cylinders with oil, but I'm not sure. When attempting to cycle the prop, nothing happens. RPM was about 1600 at the time. Any suggestions?

3. No manifold pressure indication. However I believe this is an instrument problem rather than an engine problem. Dynon Skyview HDX system.

Free OCR that you can Paste from the Clipboard 

For folks compiling study notes and checklists and such...

I know you can do some of this with apps on a phone, but I've never found a solution until now that was as painless.  I found this site over the weekend and bookmarked it with excitement.  I've been compiling study notes (something you might be doing for your Instrument rating, etc.) and was looking for a way to convert text from a picture into text without having to buy OCR software.  This site does that....straight from the clipboard.

On a desktop or laptop MAC you can press COMMAND-CONTROL-SHIFT-4 and highlight a part of a picture with text in it, then go to that site and press COMMAND-V to paste it in the window.  After pasting in the graphic, select 'TEXT' for output in the bottom dropdown box and click on PROCESS WHOLE IMAGE.  A little formatting and you're done...

If you're using a Windows 10 machine you can press WINDOWS LOGO + SHIFT + S to active the 'Snip' tool.

Here is a sample picture below for you to practice on.  It's a picture, so you can't highlight and copy the text.  Use the instructions above and give it a try!

My RV-14A doesn't like idling ...PandaCub

Odd problem with the IO-390 Thunderbolt in my RV-14A: whenever I pull the throttle completely back, the engine seems like it's idling around 650 RPM but the tach goes haywire, reading anywhere from 30 to 1250. Engine has even stalled on me twice when I completely closed the throttle during taxi back to hangar.

Engine runs fine otherwise. One Slick magneto and one Emag. Issue can be seen in this short video:

Any thoughts appreciated.

Clipped In.  After some more trimming, 1/2" at a time, I ended up with a total of 1 1/2" trimmed off at the front and back. The overall fit is reasonable. Here's the canopy, free of its cradle and unrestrained, resting on the fairing. ...


Erratic Amp Meter ...sglynn update

As a follow-up for those in the future who may read this. My amp meter starting jumping around going negative and positive. After reading this thread I hoped to find a loose wire.

I did. But the wire was only slightly loose. The nut on the battery solenoid where the lead that turns on (or closes) the solenoid switch had come slightly loose. I could wiggle the ring terminal a little. I took it off, added a little blue sealant and tightened it back on. Everything works.

But it sure wasn't loose much. But I can see that under vibration it could be letting 12V go on and off the battery solenoid and I guess that would cause a problem. The indication was the erratic amp meter.

My personal lesson learned is, don't let weird stuff go unchecked.

RV-7 D-ESOT First Flight ...Harold

Dear RV friends,
I would like to share my successful D-ESOT RV7/72535 first flight happiness in this amazing, entertaining and helpful VAF. I enjoyed working on my RV every minute and, like many of you, the building process was accomplished by up and downs, sense of achievement, and also moments to cry due to paint issues. Thank you Doug for this information platform, as a passive member I read regularly in the forum and got specific information for my project from it. I also got information about new products and the corresponding addresses to spent a lot of money

D-ESOT configuration is: ECI Titan OX-360 A4HIN (-FIS) with Silver Hawk FI, Christen inv.oil, Andair loud fuel pump , Andair gascolators, G3X touch single screen/all you can connect, GNS430W, GTR225A, PS5000X, GTX335.
The first flight was conducted in EDVE (Braunschweig) by Georg from Hamburg, enjoy viewing the video.


18% Experimental & LSA NPE ...RV6_flyer

Many of us have updated our aircraft with ADS-B out. Was reading an article and 18% of the Experimental and LSA have nonperforming emitters.

As Experimentals, the Gov't gives up lots of leeway to do things ourselves. It is great being allowed all this freedom but there is a responsibility that what we do must not only be SAFE but it must work correctly. One does not just make a change (install new equipment) and go about our merry way. We need to TEST and make sure that it works the way it is suppose to.

We as Experimental Aircraft Owner / Operators can use the FREE FAA's Public ADS-B Performance Report Request (PAPR) website to test our ADS-B out.

IF we are going to continue to be able to use non-TSO'ed equipment in the future to meet Gov't mandated requirements to use certain air space, we need to make sure that we meet the performance requirements. Failure to meet the performance requirements (and safety) could bring more restrictions and Gov't control over the hobby we all love so much.

Maintain Those Tailwheels ...rv8ch

NTSB Identification: CEN20CA114

14 CFR Part 91: General Aviation
Accident occurred Wednesday, March 4, 2020
Aircraft: Vans RV8
Injuries: 2 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot of the tailwheel-equipped airplane reported that he made a normal landing approach to the runway with a direct crosswind of 15 knots and gusts reaching 23 knots. The pilot reported that he was initially able to maintain directional control with normal flight control inputs after the airplane touched down on the main landing gear; however, when the tailwheel touched down the tail began to weathervane and the airplane veered to the right. The pilot was unable to regain directional control with an application of full left rudder and left brake before the airplane departed the right side of the runway and struck a precision approach path indicator lights (PAPI) system. The left wing, left horizontal stabilizer, and left elevator were substantially damaged during the collision with the PAPI system. A postaccident examination and functional test of the steerable tailwheel revealed that the spring-actuated key slide would stick in the retracted position within the tailwheel fork, which allowed the tailwheel to caster instead being steerable within the normal limits intended for takeoff and landing. Additional examination revealed that the slot in the tailwheel fork that held the spring-actuated key slide was slightly deformed, and that the key had several raised edges that caused the key to bind when fully retracted in the slot. It is likely that the tailwheel was able to caster during landing, which resulted in the pilot's inability to maintain directional control after the tailwheel had touched down during landing roll.

Covid induced relocation

Last Monday (03/30/2020) I relocated the Dream Weaver from Florida to Bishop Airport in Flint, Michigan. Then, I took our mini motorhome out of the hangar and drove back to Florida. Eight hours including two fuel stops going up; three days sanitizing gas pump handles driving South.

Michigan and northern Indiana were totally socked in. The photo is from 9,500 ft. Ceilings were 4000; scattered 1300 ft. Outside air temp flitted between 27 and 32F. When ATC cleared me lower for the approach I dove at 2,000+ fpm to pass through the layer as quickly as reasonable. Even so the plane picked up some light rime ice on the leading edges and windscreen. Fortunately it quickly melted below the deck. The approach and landing were uneventful.

The relocation was done because the plane is ten months into its last twelve month condition inspection; all of my tools and hangar are in Michigan, while Dolly and I expect we will be stuck in Florida till late July.

Fiberglass around counterweight ...Glen P

I'm new at this fiberglass business. I closed up the HS and VS tips with foam, flox and micro balloons. I applied some flox and then some micro balloons to the counterweight to see how well it would adhere. I adhered well. Now I'm wondering whether I could add some more micro to give it more of a finished look (after riveting on the tip). Any problems with this plan?

Initial Contact ...Barry Wallace

I am new to the site and forums and enjoying the heck out of all the good information.

I am looking to buy a RV-6A with a iO-360 and FP prop and noticed it's Empty Weight is 1,168.40 pounds and of course, Gross Weight at the factory listed 1650 pounds. This leaves only 481 pounds Useful Load. At 38 gallons fuel capacity that leaves about 253 pounds for the wife and me. With these numbers I would need to get a new wife or drop fuel.

What is a typical Empty Weight for an RV-6A?

Is the stated Empty Weight of 1168.4 a concern?

thank you so far for all your thoughts about the root cause for this engine malfunction. We have not been able to resolve the problem, yet.

So far, this is what we have done:
* we cleaned the carburetor and did find heavy floats and changed them.
* we analyzed the engine data and determined that the right carburetor must be faulty and replaced it with a new one.

The issue persists. Any thoughts?

Moving the Needle a Bit ...

The annual is almost done and the new G3X touch screens are powered up and mostly configured.  With all the CV-19 and the CAE sim training, and the son home 'remotely colleging', and the hunt for TP, the RV has kinda been on the back burner as of late.  I miss flying it, and am grateful the needle is moving toward the 'back to flying status' end of the gauge. 

New tires and tailwheel bearings, updated firmware in the 430W (so it will talk to the updated 330 (now a 330ES) for ADS-B OUT), but other than that no major annual finds from the Monk man and James.

I downloaded and updated charts Wednesday.  Boy are these screens faster than the first gen screens I had.  Going to be nice.  Need to learn some new stuff.

Homework Motivation ...crabandy

Lil' Dude was having a tough day at home pre-school this morning, I bribed him with a trip to go flying if he finished his last worksheet. I needed to use the table-saw stashed at the hangar anyway and it's been a couple weeks since I stirred the oil so it sounded like a good idea.

1500ish OVC made it a good opportunity to log a couple of approaches, we filed picked up our clearance and launched. Not half bad for being out of the cockpit for a couple weeks, I've got my 120 nailed and just slightly off the horizontal/vertical. The flight director was still stuck on Alt, I was hand flying and never swapped it to Apch.  continue


FI Fuel Metering Line Disconnected: Engine Failure on Short Final to a Military Base



U.S. Air Force Plant 42 (KPMD) in Palmdale, California. A small DoD facility in the Mojave Desert that was the home to such famed projects as the Space Shuttle Orbiter, the F-117A, and right now, my Vans RV-8. I was in no mood to appreciate the rich aviation history of the location as I pondered how I found myself on the wide expanse of Plant 42's ramp in my little homebuilt.
The flight had originated at Inyokern Airport (IYK) in California, just North of Edwards Air Force Base, and West of Naval Air Weapons Station China Lake where I was stationed as an Operational Evaluation (OpEval) F/A-18 pilot. I grew up in General Aviation, having taken my first flying lesson at age 11, but had stepped away when I joined the military, and the RV-8 was my return to the joys of GA flying. I purchased the airplane from the builder a few years previous and had flown it to Oshkosh twice, accumulating about 300 hours in the aircraft. I was beginning to feel fairly confident in the machine, as well as the owner-assisted maintenance program that I was learning under the tutelage of a local A&P mechanic.

Leading up to the flight there had been some fairly extensive maintenance. I recently had the aircraft re-wired with a full Garmin glass cockpit setup and engine monitor, and had all the hoses firewall forward replaced with Teflon-steel braid hoses for longer service life. I'd flown the airplane for 50 hours since the work had been completed, so I changed the oil, and took advantage of the downtime to rework the engine baffle seals for better cooling. The higher fidelity of the Garmin engine monitor had revealed some inadequacies in my cooling setup in the high desert heat with CHT's reaching 400F+ during takeoff, so I took on the project of improving the airflow under the cowl. I also rebuilt the tailwheel assembly. After a quick leak check, a successful post-maintenance check flight put the airplane back in service.
The next day I came out to fly, and found that the battery was dead. The battery was new, only 6 months old, but I checked and cleaned all the connections, ordered a new battery and installed it on the afternoon of the incident flight.  continue

EI Power System Review ...WingsOnWheels

Q: I am currently running one Mag and one EDIS-Based Electronic Ignition. In the future I am going to replace the mag with a second EI, but I first need to ensure that the electrons keeps flowing in the event of an emergency. ...continue

A: (DanH) Do this instead, isolated feeds and grounds. One diode, not three, and replace the useless breaker with a fusible link for aux battery charge. Well, "useless" may not be fair, as you could pull it to preflight check the aux battery output.  The EDIS feeds really only need 5 amp protection, as the EDIS system only needs a bit over an amp. 

Been flying this for a while now. Strip off the voltage monitor, push to test aux battery voltage, and ignition map select wiring, and it's pretty much what you see above. Both batteries are behind the baggage compartment in the RV-8, so there is no battery bus or main bus in the ignition system.

RV-12 Throttle Safety Wire

Q: (mowenski)  Just want to get an opinion on the safety wire shown in the Rotax Installation manual on the throttle cable sleeve. Van's section 50 Engine Controls does not indicate this step. Good idea?

A: (Tony_T)  That's an interesting question. The Rotax IM does show the cable safety wired however it is a different type of cable. With that type of cable the cable sheath can pull out of the adjusting screw.

Van's installation has you discard the Rotax adjusting screw hardware and they furnish a cable with threaded end on the sheath. So it is a different installation then that of the Rotax manual. However, as shown in this photo the choke cables are the type that should be safety wired to prevent the sheath from pulling out. I know this because I had the adjustment screw on my starboard carb choke cable loosen and allow the choke cable sheath to pull out resulting in the choke being halfway activated, rough running and plug fouling.

There is still the question of whether the throttle cable in the Van's installation should should be safety wired somehow.


Yobo update

KC Flight had more happy news this morning. Yobo asked the nurse for his release papers to sign cause he wants to go home. I think he is finally out of the woods and anyone that wants to shave off a scraggly Yobobeard will have that opportunity soon. All his labs results and oxygen levels are good so it won't be long now.

Thanks to all the RV community for your thoughts and prayers, they are working. 2020 is getting better already!!

First and foremost, I hope all are safe and well. This is a challenging and stressful time for all of us and Brown Tool and most of our customers are taking an economic hit due to COVID-19. We are working staggered shifts so that we are keeping the number of folks in our building to an absolute minimum and we are of course practicing strict social distancing and sanitizing and washing our hands and everything else in the building. We have also closed our warehouse to any walk-in business.

I have promised all of my employees that they will not miss a paycheck and that they will receive their full pay and benefits for the duration of this pandemic. I refuse to lay-off or furlough anyone. To this end, we wanted to come up with a way to generate business and at the same time help our customers, many of whom we know are tightening their budgets. Here is what we have come up with:

We appreciate your support and it is our intent to be here to support you!


$2 Tools ...Ideas that give Bang for the Buck! ...PaulvS

Found this handy rivet holder in the aviation aisle of the $2 variety store.  The low height and rubber base keeps it stable and easy to reach.


My RV Weekend ...goatflieg

Got all the horizontal cowl fasteners completed, including the nose nut plates and screws. It's not really a milestone... still have the firewall fasteners to do and a LOT of fitting and finishing work on top and bottom cowls... but it sure feels (and looks) like a milestone. Nice to make significant progress again before returning to the fiberglass finishing grind; more millstone than milestone.


The Tool Chest Droolfest Thread Ramps Up



April 6, 2020.  Issue #5,055.
  The great news on Yobo (below) couldn't make for a better top story.  Very, very grateful to get this news.  Updated the RV White Pages and RV Hotel doc over the weekend.

Yobo Update

(olyolson) Pleased to report to the RV community that Yobo talked to his wife last night for the first time since coming off the ventilator. That is a really good sign and we are hopeful that his recovery will progress quickly from here.

Overjoyed with this morning news, better than the first cup of coffee to wake you up!


Confessions of a Shop Flirt ...goatflieg

Early yesterday morning I had riveted the horizontal rows of Skybolt fasteners to the upper edge of the bottom cowl, using Pro Seal as a stabilizing adhesive between the aluminum and fiberglass. Later in the day, I went out to the shop and of course it still reeked of the Pro Seal. Yesterday was a beautiful spring day in Michigan; it wasn't too cold, the sun was shining and the air was calm. So I thought it would be nice to open the shop's garage door and air the room out. When I did, the afternoon sun streamed in, lighting up the interior and changing the perspective of the shop in a wonderful way. That garage door faces our street; many of our neighbors will walk by with their kids or dogs on such a beautiful afternoon. I wondered whether they would notice that my briefly exposed shop contained an airplane. I stepped outside and looked back in, to see what they could see.  ...


RV Pilots Honor Fallen Navy Veteran ...mturnerb

I'm sure the pilots in this formation are known on the forum. When I spotted this story it made me proud of my country and my community. Even though I'm a former Air Force guy, around these parts we love our Navy community.


Dumbest Mistake in an Airplane ...Bruce

Attempting to start a discussion and ward off boredom: tell us something dumb "a guy you know" did in an airplane. Not to judge, just to discuss. I'll start: I know a guy who in a rush to get in the air rushed through his preflight and neglected to remove his cowl plugs. The cord connecting the two plugs runs past the propeller (as it should) so as soon as the engine fired up it tore the plugs out and chewed them up and threw foam all over the ramp area. No real damage done, a fair amount of embarrassment though.

Falcon Flight Formation Clinic Update 4/4/2020 ...Check6

As we all know we are living in unprecedented times. With the extension of social distancing and limitations of Bell County where the Temple airport is located we have decided to move the clinic to the last weekend of May. The new formation clinic dates will be Friday May 29 - Sunday May 31, 2020. There will be NO back up weekend as we will not have access to facilities and it will have become too hot by June here in central Texas. ALL hotel reservations have been cancelled EXCEPT those staying at the Holiday Inn. Those at the Holiday Inn or any other hotel you made reservations with will need to be cancelled by YOU! Again, ALL reservations at the Residence Inn our primary hotel have been cancelled by Scroll. That said we know a lot of people have been directly impacted by CV-19 both physically and financially. So please take some time to reflect on your situation and whether or not signing up for this clinic is truly viable for you.  ...


KFFC Formation Team Practice

(rswalden)  We took the opportunity to fly before the Georgia Corvid-19 lockdown began. 14 RV's in all. Perfect evening to fly...

Status Report ...ZazooRV-9A

Work has continued on the 9A. We completed the fitment of the upper and lower rear fairings and removed the empennage until paintwork will start (we'll be painting the plane in my shop, but the tail, wings and fuse will have to be painted separately).
Then began the installation of some cables. Throttle, Mixture, Carb Heat, and Cabin Heat put into place initially. We've updated to the revised 9A nose gear and engine mount, no problems so far with routings etc, although if you were extra smart, you might do the firewall penetrations and some other things before mounting the engine. But it's not fatal. If you built these every day, you'd be a lot smarter. The second plane would be perfect.
Then on to wiring,,,, I don't hate wiring but I've found it to be the least documented aspect of the assembly, very slow progress, lots of head scratching.  ...


My RV Weekend

(Fearless) Moral support for another RV-er.  Flew down to Bowling Green Kentucky to lend support to Doug Rohrer for his ready to be inspected RV-9A. Bobby Hester flew in as well to check over Doug's plane prior to scheduling a DAR inspection. Doug was gracious to take me flying in his prior 9A while I was building mine and while my daughter was attending Western Kentucky University.

(Av8safe)  Chi-town fly by
Got an early start to the weekend on Thursday, given conditions were too perfect not to fly. Took a lunchtime vertical distancing break and headed North along the lakefront. Chicago approach was quiet as a mouse and there may have been two arrivals to ORD fly overhead the whole time. Getting close to doing my first oil change...looks like I will be going solo on that given the current constraints. Have enjoyed around 25 hours in this ride since picking her up in mid-February...still grinning. Thank you RM!

(SPX) A contractor friend of mine had around 500 N95 masks to spare, and a nurse friend works in a unit that could use them.. so off to the mountains I flew, about 85 miles east of me, to get the masks.

Great flight to and from (with a little cloud dodging), and on the way home, I was curious to see how the iPhone did propped up on the top of the panel, recording the landing. Not great, but not awful.

(Zuldarin)  Just a little social distancing over the puget sound.

(GaryK)  The clouds finally broke in Western Michigan. Beautiful evening for a flight in the 10.

(Paul 52)  The sky was clear and nearly cloudless here along the Gulf Coast. I didn't think I would get a a picture that was too good but I was wrong. I love a beautiful sunset.

(AAflyer) MiG Patrol. Stirred up the oil, looked up to see down, practiced a couple wheel landings, and RTB with a crisp overhead pattern for a 0.7!

(catmandu) We've been distancing at our Maryland house (where the RV still is), trying to do things to get it listed for sale. Our daughter Judy lost her job as a server, and her flight instructor has a compromised wife, so he's not interacting with people for a couple months. So Judy came to Maryland to once again get into the RV with Dad to continue on her PPL path. She asked for a flight without a dedicated plan just to wash away the Cherokee flows and feels.

My father's retirement community has (thoughtfully) gone into lock down: anyone who goes out the front gate must stay behind the door of their apartment for two weeks to protect the others. He is less than enamored with the 'room service' from the community eatery. So, we made up some of M'lady's best meals and froze them in individual meal containers.

Two birds with one stone, Judy and I flew east to west through the DC SFRA, grabbed the courtesy car from KJYO, and dropped the meals off at the front gate for Dad today!  ...


Progress ...BobbyLucas RV-12

Spending quite a bit of time in the shop with the current situation.
Was great to be able to open the garage door while working on it the other day. Looking forward to more days like that!
Hoping to be able to sit it in soon


So...I'm ready to jump in. But where to start? ...new guy checks in.

Is there a guide somewhere on what you need to get started building an RV-10? I've seen the tool kits from Cleveland and PlaneTools, but I'm not sure which kit is "better" and what I should upgrade/customize in the kits and what I should purchase in addition to the kits. Being that my location is on quarantine right now, and looks like it may continue to be through the end of May, I'll have to order most additional tools (Finer grit sandpaper, etc...) online, so I'm hoping to find a solid starter list of things I'm definitely going to need so I can get ahead. I'm ready to start placing orders on Monday!

Confusion/questions on Fiberfrax installation...Reflex

Thought I'd start a new thread instead of hijacking an old one....

After reading several threads/posts on adding a safety margin to the firewall, I've decided that this is one of the very few modifications I'd like to make on my RV-14. However, I'm still a bit confused. I'm planning on using Fiberfrax and Dan H's method on the firewall. Dan has been kind enough to give very detailed drawings of his method. However, I'm slow enough that I'm not quite understanding when or how to mount things to the firewall.

If we put the Fiberfrax and covering on first, it appears that items on the firewall would have a very "soft" mount. If we put items on the firewall before the Fiberfrax is installed, then we could/will have hot spots in the event of a fire. In a perfect world, I'd like to install install the Fiberfrax first and then mount everything to the firewall, I'm just afraid that they won't stay put. I've cheated and put Dan's pictures and a couple other examples below.

In what order do I install the items on the firewall, before or after Fiberfrax?  continue

First Flight - RV14A ...Allan Stern (Steve T. post)

We are posting this on behalf of Allan Stern. CONGRATULATIONS!!!!!

"I made my first flight this morning. Plane flew just like an RV. A few minor little problems like an aileron might slightly be out of adjustment giving a slightly heavy left wing, or pull to left. Temps were green oil temp 195 for a new engine. Very docile and no surprises.

Kit #140507 QB
19 months total time from first kit till DAR inspection
15 month actual build time minus QB wait time of 3 months and 1 month vacation"


Going in a circle ...PaulvS RV-6A

I went around in a circle today, April 1st carried over!

I've been checking over the fuselage frame and noticed the smallest F-612 bulkhead at the tail end was installed with the flanges facing forward. But there is a one-line statement in the construction manual that says to orient flanges backward for the -6A (versus the -6 which has two parts riveted together, one facing forward, one facing back).

I decided to make another bulkhead, similar to the 6, so as to have flanges facing backward as well as forward.

Made the part, went to drill the parts together, checked the rivet spacing on the plans and noticed a revision to have the flange face forward on the -6A!

So a morning's work for nothing (other than some ongoing education).


Addition made to all RV tail/empennage kits ...Mothership Greg

We recently made a small addition to every RV tail/empennage kit we ship. We're now including our OP-51 "Sheet Metal Basics" kit, a small and practical learning exercise that folks can use to practice/develop their skills before jumping into building the actual tail kit. It certainly doesn't replace our more advanced practice kits like the toolbox, lightbox sign or practice airfoil. In other words, this one ain't meant to be purdy -- It's practical! Think of it as an extra opportunity to try things before you jump in, if desired. It's especially good to use for practice in *fixing* mistakes -- something we all need to feel confident in. Worried about drilling out and replacing rivets for the first time? Use this little kit to practice and don't worry about messing it up while you're learning. We've used the "Sheet Metal Basics" kit with STEM educational programs for many years to help kids learn the basic skills, too.

Included is an instruction sheet, aluminum sheet pieces and angle, plus the necessary hardware -- the same sort of hardware that is commonly used in building our aircraft kits.

Don't need it? Cool! Use it to teach a kid from your neighborhood how to use the tools and build skills. And be sure to post or send us a photo of you teaching them! Spread the opportunity and help construct the next generation of builders!

You don't have to order a tail kit to get it, by the way. I mean, we certainly would like it if you did. But, if you already have your tail kit it's also available to order online at our web store for the princely sum of $10 plus shipping. You can search for "BAG SHEET METAL BASIC" to find it.

And since history tells us that someone will comment or ask: No, we didn't increase the tail kit prices because of this.


Fitting everything behind an RV-8 panel ...Cannon

I have a G3X Touch panel that I've finally mounted in the fuselage.

When Stein built the panel (which is beautiful), the harness lengths (12-18") imply mounting most of the boxes immediately behind the panel, I suppose either attached to the next bulkhead or on mounts I'd fabricate between the bulkhead and crossbrace. The GTX45R and GTR20 are the biggest boxes by far and the two I most worry about. The others don't concern me too much.

I need to mount a GTX45R, GTR20, GAD 29, GEA 24, grounding FOT and the avionics relay. None of them have harnesses long enough to mount very far away.

I could build an extension harness for either the GTX45 or GTR20, but both would require sourcing several connectors and pinning ~18 wires/shields.

What have others done?
