RV-12iS teen-build project in Italy ...Luke in Italy

A new RV-12 school building adventure started here in Italy, together with Istituto Martino Martini - an aeronautical high school located in the northern side of our country - I lead the project that involves teens from 16 to 18. They have the tail cone almost completed with wings and fuselage already ordered.

Using the kit to build and fly an RV (that will be registered under E/AB), we teach the students to learn teamwork, leadership, focus, and hands-on skills to prepare them for the real job world.

The program is organized for different fields of application divided into classes so the students are guided to develop skills in metal building, electrical system, avionics installation, engine, and system installation.

It's a great honor to be part of this project.


West 105 got really hot. Normal?

Mixed up a batch of West 105 / 206 (slow) with a very large quantity of cab-o-sil. I've mixed 105/206 several times, but this was a first.

Within about 3 minutes, the mixture got very hot. I was using an old plastic take-out food bowl and it got too hot to hold. I even started to see steam / smoke come out of the bowl. Within 10 minutes, chunks started to form in the mixture. I was using 206 - SLOW hardener - but this hardened up really fast.

I've made 10-12 batches of West before and it has gotten warm, but nothing like this.

I used about 7-8 squirts of both fluids (I use the measured pumps to get my mixture right.)

It is about 95 degrees today. Probably 90+ in the hangar right now.

Is this normal? Or did I make a big mistake somewhere?

The parts I was bonding / filling both appear okay. Warm but not hot. It's a thin layer applied of the mix between fiberglass and aluminum.

I left the bowl outside on a pile of gravel in case it catches fire - still very hot, but no flames.


Simple Fix

I just flipped the standard Van's bracket over to other side (with a little bending to clear the pan) and put the bolt and spacers on on the throttle arm on the other side also:

Micro-Stop Cage Rebuild

My micro-stop cage was behaving erratically, so I took it apart and found a bearing that looked like the attached image.

I decided to attempt to rebuild it and posted the details on my build log here:


EAA Founder's Innovation Prize Grand Championship

New to me RV-3

Hey guys, I'm new here. Already paid up on my due's. I just recently purchased this wonderful RV-3. Its an A with a B wing added later. This is hands down the best flying airplane I have ever flown outside of maybe an Extra 300L. I am literally in shock at how good it is. I had a handful of hours in an RV-7 15 years ago along with an hour refresher in another 7 recently and felt fine hoping right in after a little coaching from a bud on the quirks of the RV-3. It's really true what they say about the RV-3, it is stupid good. Thanks for having me along for the ride, look forward to meeting more of the RV guys in the future! Feel free to impart wisdom!


First Post / Initial Contact ...Huntsville, AL

Humble Request (RV-10 Sample Ride)
Considering building an RV-10 and would like a (short/demo) ride to add another piece to my mental puzzle. Can certainly buy some avgas to support the effort -- hopefully, that is enough to persuade someone...

BTW, I'm in North Alabama (Huntsville area, specifically Toney in case you are familiar).


Houston area monthly lunch (June 2021)

Posting this one up a bit early this time in coordination with getting this on the VAF calendar, in my continuing quest to get more attention and attendance.

The 19th will be the usual third Saturday, and we'll be back at Hooks this time for burgers at the Aviator's Grill. Meeting time is the usual 11:30 as well.

Weather permitting, I'll be flying the Arrow up out of KTME, and I'll have a couple seats available for anyone in the Katy area who wants to avoid the drive - just let me know. Hopefully we're finally through the rainy season, because I'm tired of 1) not flying, 2) seeing my lawn turn into a lake, and 3) hordes of mosquitos.

See you there!

RV Weekend...crabandy PIREP

Finished my long weekend with my favorite lil' dude who demanded to fly home with me. He's been RV flying most of his life, bottles and carriers to boosters and sippy cups. Last year I had to set him on the wing walk so he can get in/out himself. Several months ago he passed his entry/egress checkride from the ground and has been solo'ing in and out of the airplane without incident.

I'd finished things up and was ready to push the airplane out of the hangar when I found him here, casually perched on the slider rail with 1 foot swinging. Ready to kick the tires and light the fires......That's my Boy!


Too Close ...motodave

Looks like I get to move my throttle cable mount over...

...This is too close and can't really even get the heat shield in place. I will attempt to flip the bracket over as others have done.


Aerofurb's RV-12 Pitot Cover

(from a 2014 post)...re-spotlighting. We fashioned a pitot blank from a standard aircraft hose blank with a 'remove before flight' key fob (since upgraded to a Red Bull 'Flying Bulls' version!). A small hole prevents pressure change problems.

Prime reason for it is to prevent things climbing in and blocking the pitot tube, secondary reason is to prevent blood loss.

A secondary method is to leave the tow bar attached. Now I am the number one advocate of removing tow bars before you let go of it but on the RV-12, it does help keep peoples skin away from the sharp end of an RV-12....


Left Side Throttle ...koupster

I put in another cable that attached to the inside of the throttle arm. You're going to have at least two cables anyway. Had the cable fabricated locally with threads for a rod end on both ends. Didn't want the slop of a clevis and pin on the cockpit end. Built a throttle lever for the left side instead of using the standard push-pull throttle control. Hinged the throttle lever on the floor so that the motion was more linear than if it had been hinged higher.

Here's both cables attached to the throttle arm

Vans/VAF folks are awesome!

I've been contemplating a build for years -- of course Van's is on the top of my list. A couple weeks ago I posted on the forum asking to check out some aircraft. I was shocked how quickly folks responded in my area, and how accommodating they have been! Thanks y'all!

A special shout-out to Tanya for taking time out of her busy schedule to give me the "complete Van's experience." It was a blast!

Also, thanks to the Dan and his cadre at Tango Flight!

I'm looking forward to getting started!



The Man, The Myth, The Legend

A neighbor at my home/airpark (50F) bought a Cub and was having it delivered this past weekend. It's ironic that my neighbor flies F-16's for a living, but is having to get his T/W endorsement for the Cub. Met the fella who was delivering the new Cub, from Alabama. He told me he also flew an RV-8. I asked him if he was ever on these forums, and he just grinned. He'd told me his name was Dan, but I didn't catch the 'Horton' part. We got a good laugh out of that:


Panel wired for now

Just have engine sensors to do (awaiting engine/finish kit), and transfer my Garmin GTN 650 Nav/comm out of my other plane.


Getting the Fuse Through a Small Door

here's how I had to do mine.... (excuse the MS Paint artwork) The gear width is about 8ft


Spreading Ashes

Original built for a Cub, and a very nice electrically actuated adaptation for underwing on an RV, credit Vlad and some bright guys in his circle.

It's the right way to do it. I'll be building another one for the RV-8 in the not distant future, attached to the same six underwing points as the 50 cal gas gun.

A Great Lakes biplane flipped at our airport Monday morning on rollout, resulting in the airport being NOTAM'd closed for a few hours.  I was eating my breakfast midfield watching planes land, saw the biplane roll by after touchdown (everything looked fine), took a bite out of my McMuffin and heard a tire squeal and a thump.  Drove down with a handheld, everyone already out in the 30 seconds it took me to get down there.  Both occupants OK.  I called the airport manager Rob Reece to get him in the loop about a minute later.  Due to the proximity to the runway the field was shut down....long enough to have to divert some RVs that were out for formation practice to nearby KAFW.  Heat index of 108*F didn't help.  Sorry gang.

Sad for the airplane, but grateful the people were OK.  The POA (Fly52F.org) will have that landing light repaired quick.  They work fast.  Need a Contract SIC?

My RV Weekend...


Why do the plans call for this bolt to be upside down?

This is the bolt that holds the Exit Air Attach Contraption, er Brackets to the firewall. It is supposed to be installed head down.

That seems odd to me, so I have mine with the head up.

Does anyone know why the plans show it upside down? All I can think is that it keep the AN365 nyloc nut out of the hot air flow, but I can't believe that would matter.


Smaller Trailers

We in Europe have smaller cars than in the US , thus our trailers are smaller as well... I had to make a spacer and invert my left wheel to fit it onto the trailer.. But it worked out perfectly.

I drove from the shop to the painter and from there to the airport.
My friend who is a police officer was on duty and therefore I had him drive in front of me and he stopped all other traffic so I could gently drive to the airport


My nuts are galled, 25-05 step 8

I installed the AN3-13A bolts then realized I chose the wrong Cover Rib so removed the bolts and found badly galled threads. We all know these all metal locknuts work like platenuts (nutplates?) and are deformed to apply an interference fit as the locking mechanism. But is it normal to get this kind of galling? The photos show the relative location of the nut when installed. The bottom of the nut is not deformed and does not cause galling. Nylock nuts are re-usable but I have not read that all metal locknuts and the bolts they are installed on are one time use only. I will not reuse these. I this normal?


Brake / tire issue

I had a wheel lock up while taxiing at Tuscon yesterday afternoon about 3:30 pm.

The weather forecast indicated 110 degrees. My OAT gauge read 120, and the temperature on the tarmac was probably 150. I had a 2-mile taxi from the FBO to the departure runway. I was behind a slow-moving airplane and had to apply occasional braking even at low thrust, and also some braking for differential steering in a modest crosswind. I was concerned about overheating brakes and mentioned it to my son.

Shortly before reaching sunup area, the plane made a hard turn to the right and came to a complete stop. I tried starting again and the plane continued turning right, so I shut down the engine on the taxiway, notified ground control, and got out to investigate. I found the wheel fairing resting on the ground, with the tire completely flat. I was able to remove the fairing, and found the tire pulled off the rim, the tube flat, and the brake locked. The right wheel would not turn when I pushed the airplane. I removed the brake pad, pushed the airplane off the taxiway, and had a 2-hour adventure with the facility manager and three FBOs getting the plane to an FBO. I'm grateful to a bunch of kind people at TUS. This morning the mechanic replaced the tire and I reattached the brake pad and did a ground test, then ferried the aircraft back to KCCB in SoCal, thankfully with a short taxi to the crosswind runway and all before it got too hot.

I'm looking for ideas about the root cause. I have standard Vans RV7A Matco wheels and Cleveland brakes. I think the most likely reason is that the brake locked. I don't know too much about brake failure, but the temperature and length of taxi are both much higher than usual so I suspect it could be heat related. It is also conceivable that something such as unseen debris on the taxiway could have popped the tube, and then the tire deflated, and somehow this led to stresses that locked up the brake. In any event, the brake behaved normally when I reassembled it this morning.

As another possible clue, I've been dissatisfied with my right brake. The plane started flying 15 months ago and I have about 200 hours on it. The brake pad squealed frequently until I replaced it, and occasionally still squeals. The braking action is less effective than I'm accustomed to in a Cessna or Bonanza, and I usually brake gently and have a rollout of more than 1000' before coming to a complete stop. The brakes generate a lot of fine dust that needs cleaning. I'm also not wild about the tube design; I think I follow all the directions about talc powder and repeatedly inflating and deflating but I've had to replace two failed tubes so far on the airplane.

I'm also looking for feedback on a remedy. I've worked on the tires enough times already that I'm feeling fed up, as well as concerned about a ground loop if it fails on landing. It looks like the Beringer wheel and brake system is more reliable, and possibly has better braking action. It's fairly pricey, but I'm considering replacing all three wheels and two brakes with Beringer. Any thoughts or alternative suggestions?

Thank you,

David Harris

  Hot.  We drove down to Austin and back for family stuff, and when we got back home Sunday afternoon the 109*F heat index kept all ideas of a short trip out to fly the RV under the nearest a/c vent.
  Hope you got to spend some quality time with your plane/project, and the a/c vent wasn't too far away.

2021-06-05: Hangar move-in


Help me identify hangar floor chock

Just moved into my new hangar and previous occupant left a neat floor mat / chock behind. It seems to be attached to the floor with adhesive. Pretty cool, but I can't find them anywhere online. Can anyone identify this thing and know where to get more of them? All I see is it says "STOP SIGN" on it.

I like it because it's fixed in place and you can roll the plane over it manually to put the gear in position, but it can't roll off on its own.


Loss of GPS and ADSB

I am flying an RV-12 with a Dynon HDX. I am not the builder so my understanding of the systems is not great. There is a Dynon 2020 GPS antenna.

I get a warning that the ADSB HAS FAILED AND LOSS OF GPS.

Has anyone else had this happen and where do I begin to correct it?

The "BIG" move


Very exciting! After waaaay too many years, it's time to move to the airport, start the Vans / FAA paperwork and make initial contact with a DAR.

I'm asking for help/ideas/critique/advice for the critical move fuse only/engine mounted to the airport.

Due to the insurance issues I've run into (they'll give me my money but potentially subrogate the transporter) for tilt-bed auto transporters / riggers with trailers in my area (cars and trucks only), and the width of rental trailers for the wide gear, it's looking like a U-Haul 26' box as others have suggested is my best option. Currently in my area they all have aluminum floors.

Here's my proposed plan based on only having the side rails of the box of a 26' U-Haul to work with.

- Tail first (home built ramps for the mains and the supplied walk board for the tailwheel).
- Tailwheel on my stand.
- Tailwheel leg secured horizontally with 2 straps, Left and right to secure aft horizontal movement. It CANNOT swing.
- Strap over the fuse forward of the F-881B's and down to secure vertical movement.
- Chocks fore and aft of the mains
- VERY tightly wedged (big hammer)(don't bow out the walls!), 2x4's cross-wise over/on fore/aft the chocks to secure.
- For additional fore/aft movement safety:
2 lengths of webbing through the spar carry thru. 1 directed forward and one aft.
- Low pressure tires


Elevator into practice project.

I should have walked away and come back to it.


Flaring bent tubing

I am building the selector valve to filter fitting. The tube has a 90 degree bend and then a 180 degree bend to connect to the filter. The end of the 180 bend has 1/4 of an inch straight before connecting to the filter.

Problem: I cannot flare the end near the 180 bend before as it will then be crushed by the pipe bender. To be able to bend 180 degrees without collapsing the tubing, I had to have an extra inch of tubing downstream of the bend that is then trimmed off. The problem is that I cannot get the AN818/AN819 nut and coupler on. The nut navigates the the 180 curve easily but the couple won't go past the straight section.

I've used about 4 feet of tubing trying to make this work.

Anyone have any ideas?

P.S. Using a ATS flaring tool, the kind that has blocks that grip the tube and then a flaring tool that you screw down but hand. Requires about 1/2" of tubing to make the flare.


Carb Throttle Arm and Cable Bushing

We are doing Dynamic Prop Balance on RV-12 with 370TT. IPS started at 4.6 and now at 0.6 without too much fuss. We are also doing carb balance and notice throttle arm / cable bushing wear on both carbs. See photos below - throttle arm photo is out of focus, but you can still see elongated hole


Broken engine/gear leg mount

I'm not sure if there is anyone out there who can help but it's worth a try. I have an RV-6 that I built and have been flying for 19 years. I have a little over 1100 hours on it and almost 2300 landings logged, at least half of them on grass. On Memorial Day I landed at my home airport in North Arkansas and noticed when taxiing to the hangar that the right wing was significantly lower than the left. I first thought I might be getting a flat so I got to the hangar as soon as I could before it went completely down. Unfortunately it turned out to be the engine mount which surprised me since I have not experienced any landings lately that I would consider rough. I am thinking now that it may have been cracked for a while and the last landing was the straw that broke the camel's back.

At any rate, here is my problem. The technical advisors at Van's looked at the pictures and have recommended not attempting to have it welded, but to replace it with a new mount and new gear legs which are match drilled by the manufacturer. I have ordered it but received an email yesterday stating that the parts will not be available until September 13. I' m wondering if anyone near me would have the mount in their kit but might not be ready to use it in the near future, and might be willing to swap out with me. The mount that I have coming is the 7 DYNA-1 O-360 for the 6,7, or 9. If not too far away I would be willing to come after it and pay a little extra to make it worth your trouble. I could have Van's ship my new one to you. Oshkosh is coming up and I sure would like to take my RV for the 18th time. Sorry for the long post.


C-FGWW Panel ( ff 2011 )

Here's my take on basic VFR. The glove box was sized to fit an open Canada Flight Supplement, and thanks to EFBs is now just the glove box The round tube on the lower right is another storage bin and is housed in the oxygen bottle mount.
I fly with an iPad on the right knee running ForeFlight and the checklist on the other.
Eyeballs outside 90% of the time to avoid running into things.
The switches are grouped by function.
This is a 10yo build so big screens weren't a thing but I still like the minimalist approach. >$200 a year for my ForeFlight subscription, no other fixed costs or updating. But I must admit I don't fly in that 1000/3 East Coast muck with a ton of traffic.

Moose Creek with the BIL and Cousin ...crabandy RV-7

Short story long.........

My sister in law asked if I'd take my brother in law on a trip for his birthday, he needed a vacation. She suggested something remote, camping, mountains, basic guy stuff. Wasn't sure how I was gonna make it all happen but I started running the options. I'll be darned if M McGraw RV14 extraordinaire/PJ camper/Formation flyer didn't contact me about places to stay between Tn and Mt on his way west.

Schedule wise I had to leave sooner, quick oil change/FWF inspection/tire inflation and tailwheel check and lube.


IFR Shorthand for the Bumps

Sometimes I help set up (10) different approaches during a sim session...while looking up stuff in the QRH. Fast and dirty and the free hand is tuning a radio or pushing a button. I'd just drop the pen...

I got to thinking a few days back about the symbols I currently use on the charts page of GP while I'm in the sim at the supplimental gig. They have evolved over the last year and 173 sessions, transfer over to the RV world nicely, and allowed me to free up a second here and there, not to mention mental bandwidth, for those other things I'm required to do (calculate landing speeds, monitor fuel levels...they don't auto crossfeed, etc). Not to mention an engine is usually shut down, an EFIS or two is probably dark, it's 'night', and the client has their hands full. I'm almost certain to get the occasional "Are we cleared for the approach?" or "What is the next altitude?". I don't remember...glances at iPad... ;^).


RV-10 Door Hinges ...Brendon PIREP

I used some scraps from the doors to cover over the pocket. The 1/2" x 1/8" foam seal goes right over and seals nicely. I had to move the door strut bracket down in order to avoid interference with the door.

  Had the privilege of taking one of the instructors at CAE where I do some part time side work up for his first RV ride Wednesday morning.  Most of his flying career used JetA, so this was a little different for him.  I briefed him on the sensitivity before T/O, and when I passed the controls over his first words were, "Whoa!  This is sensitive!"  Funny how we're so used to it and it's just our "normal".  He dialed it in over five seconds and was rock solid.  No pictures (sorry), but it felt good to generate another RV grin.

Milestone: First GPS Power-up ...James Geyman


Moved canopy back solo and hopefully fixed canopy leak for good.

I was able to pull the hinge bolts and move the canopy back without any help. Moving blankets close to the canopy CG did the trick. I spanned the gap across the hinges with a piece of aluminum and then added a piece on top so that it was flush with existing. This made the gasket continuous. I also siliconed the corner.

To get canopy back in I moved it on each side like 1/8" at a time and could grab the side and wiggle it to get the bolts back in. I have the access panels. Probably been next to impossible to do it solo without them.


Final Fuse Push ...PilotjohnS

Now that the panel is done enough to install, I have been working to finish all the fuselage stuff to limit the amount of work I need to do on my back once the panel is installed.

First off was to finish the fuel lines. I have been putting this off because I didn't want to keep hitting them as I walked around the airplane. Now it was time to install. My hat is off to those who did this per the plans; I was not able to get a single line from the valve to the wing roots, so I broke it up into three pieces. Ya the extra breaks have more potential for leaks, but I am using 200 PSI fittings for a maximum of 8 psi; so I think it will be OK.

Next up was figuring out the GPS and XM antenna placements. I was planning on putting them just forward of the firewall, exactly like what is NOT recommended due to heat. Then I thought about a place on the glare shield, but I didn't like seeing over them all the time. I thought the rear turtle deck would not work because I was afraid the canopy would not slide over them. Turns out someone posted a picture on these forums and guess what, the canopy clears them by a large margin. So I ended up installing the GPS antennas in the preferred locations on top the fuselage. Now I have to spend $200 on 50 feet of RG400 cable to run to the back. Oh well. Here are my antennas installed temporarily so that I can run the antenna wires. I think this is going to work out great!
I also installed the parking brake handle. I had to redo the idiot light switch. (I was an idiot the first time). I had it activate when the lever pushed on it, but a slight shaking would cause it to be intermittent. I changed it so that it is activated when the lever sweeps past it; no longer susceptible to vibrations.
I still need to torque everything, and then torque strip.
Next up is prep for the engine mount install, then install the panel, then hang the engine. Lots to do.

Low Oil Pressure today in my RV7A

I've had the plane about a week. It has a Titan IOX-360-A4H1N.
All looked good on start, run-up, take off and initial cruise, but after doing some flight review maneuvers, such as slow flight, stalls, steep turns, I noticed that the oil pressure was at 55, with manifold pressure up around 22 and tach about the same. It quickly dropped to 50, at which point we decided to return to the field and land asap. The oil pressure snuck back up to 55 or 58 on the way home, but never got into a more comfortable zone.
I am now beginning the process of diagnosing and research. I pray that I am not due for a rebuild or something else very pricey. The engine has just over 1200 hours on it.
There are six quarts of AeroShell 20-50 in the engine.
The prior owner has advised that an oil and filter change might correct it. It has been about 43 hours since the last oil and filter change.
I am looking for advice on how to diagnose the issue, and potentially trace it to a sender/gauge issue. Worst case, it points to a need for a rebuild, and while I truly hope that isn't the case, I do want to be safe, as I fly out of an airport with no places to land on climb out, so I need to minimize the risk of engine failure.

From flatland IL to mountain AZ ...tcoverst

I recently moved to northern AZ from central Illinois. In order to complete the move, I got to make a great trip in my RV.
Trip Prep
I knew that I had a lot to learn because my destination (northern AZ) is very different in topography and elevation from what all my flight hours up to this point have been (central Illinois). After a short wait I secured a ramp parking space for the plane at an airstrip in the mountains with an elevation of 6700'. I started reading anything I could find on mountain flying principles. The most helpful resource I found was the "Mountain Flying Bible Revised Edition" by Sparky Imeson which I read cover to cover and used extensively in preparing for the trip. I also starting soliciting routing advice from anyone I could ask. I asked on the Van's Air Force forums online and received a lot of helpful tips and landmarks. I asked local pilots at my intended destination and I asked the experience of people in my EAA chapter 563 who had flown out west. All of the input was helpful and moved me from concerned about the trip to excited about it. I started scouting for a good weather window across half the country for my route of flight. Once I found one, I booked a one-way commercial flight back to Illinois and began to get the plane ready for the flight.
Trip Complications
I suppose complications are inevitable - regardless of the planning that goes into a trip of this length. On the morning of my departure, I showed up to the airport prior to sunrise. My plan was to preflight in the dark and then be wheels up by sunrise. My preflight held a surprise for me. Despite having flown just fine the day before, during preflight, my autopilot roll servo failed. Any attempt to engage the autopilot returned error messages about a failed roll servo. I unscrewed my access plate in the wing and checked connections. Echoing through my head was the sage advice given to me multiple times n the EAA hangar, "It usually is something simple". Unfortunately for me, it was not something simple to repair. Having checked the connections and re-seated them several times, I still had no autopilot available. Now an hour later than I intended to leave and still on the ground I had a decision to make. I could cancel the trip in light of this change. I would forfeit my weather window and of course the expense incurred up to this point in getting back to central IL to fly out. Or, I could press on with the proposed 10 hours of flying time knowing that I would have to hand fly the whole thing. My evaluation considered these factors:
1. Losing the autopilot is not a flight safety issue necessarily. I decided that I do not like the flight safety margins of single pilot IFR flying without an autopilot - so if I elect to continue then I am ruling out filing IFR at any point. If IFR conditions develop I will have to wait it out on the ground.
2. No autopilot will mean that fatigue will enter into my pilotage much earlier than normal. But, I planned the trip to take two days and I had separately thought out different stopping points for my first day. If I elect to continue I have to coach myself to pay attention to my level of fatigue and be willing to stop early if needed.
I decided to continue and went wheels up around 7:30 central time (I am sure I should be telling you that time in Zulu time - but I cannot for the life of me keep zulu time conversions straight!)  continue

My RV Weekend


Initial Contact ...ryane67

Hope I don't regret this!  Hey all, I'm Ryan, been lurking here for about a year trying to decide what to do as far as these wonderful aircraft do... was first thinking I wanted to build a -10 but then I realized I'd never really use 4 seats.. was considering a -9 for awhile but it just seemed like the 6/7/9 was going to be too cramped of a cabin for long cruises and the useful load might be a bit tight as well with me and my wife and any stuff we want to take.

I figured the 14 was the right choice so I just submitted an order form for a Tail/Emp kit.. It feels like a huge commitment but I know it's a long process to build one of these planes.

I've always liked building /assembling things, do most of my own automotive repair work, my own home improvement projects, etc, this seems.... almost like putting together a lego set by comparison, just that it's going to take longer and cost a whole lot more


Need Help Analyzing Borescope Images - Leaking Exhaust Valve on Lycoming O-360-A2D

Fired up the O-360 in our RV-6A last week and it ran rough, with EGT in the #3 cylinder failing to come up. Shut down the engine and pulled the plugs - they looked find. Then, a compression test and we could clearly hear air entering the exhaust system. Bought an inexpensive borescope, and the following are video clips and images of the exhaust valve in question. I've not analyzed borescope imagery before and could use some help with what these show. I'm reading everything I can find on leaky exhaust valves and ordered a valve guide reamer from McFarlane in case this is a stuck valve. I'm also looking into lapping the valve in place since it appears to me (remember I've never done this before) that there is significant pitting on the valve and the seat.


RV-8 and the Smoking Rivets

This weekend turned out to be a good time to replace a couple of smoking rivets.


Resistor Rating

Need to reduce the voltage of 4.8v by using, per GRand Rapids documentation, a 200 ohm resistor. They call this a red black black black band resistor. Since my fuel pressure is wonky, thought I"d look to see what I have installed ( did not build) . Pictured is what is installed...not red black black black. Anyone electronically knowledgeable to say what I have installed? Looking on line on how to read is confusing, and doesn't fit anything. Also, do you happen to know what 4.8v will be reduced to by use of my installed resistor?

Blue is 4.8 voltage pin/line, Gray/black is the wire going to VDO fuel pressure sender ( carb engine) .

Yes, I see what appears to be a burned, scraped, damaged gray/black wire, but not cut, appears to be solid.


First Flight Reported on the Mothership


Repairing Poorly Countersunk Holes in Fiberglass

One would have thought that by the time I got to attaching the empennage fairing I would have known how to countersink. Not. I am using tinnerman washers to hold the fairing in place, but I know I can do better.Not. The nut plates are attached. How do you recommend I fill the poorly countersunk holes and start over.


Rear Seat Throttle ...vlittle

For the throttle, I used a 1/4 threaded aluminum rod, a rod-end bearing with an aluminum stand-off bushing and a ball-end from Macmaster-Carr. I also added a trim switch. The flip-up rudder pedals were from FlyBoy.

Epoxy is chipping or delaminating on my cowl

Would like to hear some opinions on what I should do here. I have an RV-4 that was built in 1991 and it appears time when they installed the piano hinge on the top and bottom cowl they put a 2 to 3 inch wide piece of glass under it and used the same epoxy to do a final coat on the inside of the cowl.

Now 30 years later (it's only flown 280 hours) it seems like there was never a bond or that bond is no longer there. Near the strip of glass it is completely delaminated from the layers below. In the middle of the cowl it looks like little air pockets where the top most layer of epoxy has lifted.

What I've done so far is take a plastic scraper and ran it over things to flake off what is easy to flake off. On the top cowl I went ahead and broke the glass strip near the piano hinge.

Should I just leave it as is for now and keep scraping it off over time or is there a need to sand it all off and put a thin coat of epoxy down? I am not sure if he was using polyester resin or just skipped the step of scuffing before applying epoxy so it would stick.



6/7/2021.  Issue #5,334.
  A short note today reminding the forum users here of the importance of the civility rule (rule #7). I've noticed a trend as of late of people taking occasional shots at each other, of barbs and digs getting taken and thrown in a reply. Maybe it's because (what I've experienced) on other boards I've visited civility has eroded away in large part. Some of those aviation boards seem to be not far off from a dodgeball game with grenades. If you visit them you might assume that behavior is OK here.  It is not.
  I'm not mincing words. If you can't live with being 100% civil and polite in your posts here, then you need to leave.  This site isn't FaceTrackYou, InstaThis, TwittaThat or TikTokToejam..... and never wants to be.  Dopamine-driven feedback loops...something to research if you're curious.
  Please keep it RV-related and VERY civil (I'm raising the bar on this today). Don't include a quark, lepton or boson's worth of politics, and benefit from what a Van's RV board that stays on topic can do for both you and the hobby we care so much about.
  I think this site is an oasis in a web and world gone bananas, and I've bet everything on it staying online.  Please help me keep it awesome.  And thank you.
  Sorry for the bad cop routine.  Gotta go into character every so often.

Around the Lake ...Steve Melton

I have never been to the Michigan Upper Peninsula (UP) so I thought I should go. A quick trip just to look around and try my hiking backpack. A Thursday weather check for Friday and Sat looked decent. Book a AirBnb for one night and pack lightly. I looked out the window Friday morning and I was fogged in but it was a warm front and those usually burn off quickly. Weather was reporting 600 ft and scattered but it all burned off quickly.

Initial Contact

RV14a - Broxy's Bird (NZ)
Hi there from down under in New Zealand, I'm in Whakatane (No that isn't a swear word) in the Bay of Plenty and its not called the Sunshine Capital for nothing. My RV14a Empennage kit arrived a little over two weeks ago, inventory is done and I'm itching to drive my first rivet on the vertical stabilizer. The lead times are so horrific that I've already placed my order for Wings & Fuselage so I have about 8 months plus shipping time to get the tail feathers built.

I've wanted to build a Vans for over 20 years, did buy an RV7 empennage many years ago but never started it and went travelling instead, the matched hole computer aided design of the RV14 brought it back to the top of my bucket list, now I just have to build it.


Orcas Island, Washington to Tennessee ...Capt Sandy

Hello VAF'ers,
June 4, 2021
Depart KORS at 9:25am, 5 minutes ahead of schedule. WINDY at Orcas Eastsound airport with low pressure system moving in from NW. Our destination is Tennessee (hopefully by Monday), so we wanted to head mostly east, but thunder storms in the vicinity of Missoula, so we decided to fly SE instead.


Officially a Repeat Offender ...Rob Holmes

I just placed an order for the RV-7 tail and wing kits. Its been 15 years since I started my -3B, 10 years since I finished it, and 2 years since I sold it. I dabbled in an Extra 300 for about a year, but the lack of performance in every area other than aerobatics drove me to sell my share. I kicked around the idea of a bush plane, but again I had a feeling the lack total performance would lead to the same frustrations I had with the Extra. I'm excited to be back and looking forward to another build!


Space for Back Riveting ...Rich Pulman

I found a long piece of rolled steel at a local supplier ($10) and a couple pieces of carpet of equal thickness at Home Depot. Works great!

P.S. It was just a coincidence that the length of the steel matched the width of my bench!

Panel ...Chris Mon

I use the 10" screen on the right side all of the time. Usually I keep up weather or destination airport information data or just an expanded chart (VFR or IFR) enroute. As far as the center position, you will need to remove center stack structure.



6/4/2021.  Issue #5,333.
  Splash pic is from a flight last week - noticed the RV-8 reflection on the panel and thought it would make a nice picture.  Full size is pretty neat - I wondered after if putting some mirrorized mylar on that patch of panel would act as a sort of mirror for the right side.
  Wishing you and yours a happy, safe and RV-filled weekend.

Roll servo bolts

Q: Apologies if this has been answered before, but a search did not show what I was looking for... I need to replace a roll servo, going from Garmin to Dynon. I found this pic today in the forsale section, which made me think of it...
Question: The two bolts holding the mounting bracket in the wing, do these have nuts on the backside, or do they bolt into nut plates? Did not want to loosen as did not see an easy way to get to the other side if are held with nuts, although logic would dictate a nut plate of sorts... Did not build...
Thanks, ed



That day you get your endorsement

The end of a long day... First flight plan, first Dual XC, landing at KOXR, meet instructor there, land at L52, only 2300 ft of runway to land on when you're used to 4100 or 6000, land at KIZA, 3 landings there, get diverted from KOXR to KSZP, where instructor lives, get endorsement for KSZP so I can fly to instructor for continued lessons, then fly back to KWHP.

That was a loooong day in the Slippery Blue Devil for this student. A video of a landing at KSZP, late in the day.

Awesome show!

These guys put on an amazing show! Everything from start up to shutdown was displayed to precision. I really enjoyed seeing the formation changes after each pass and their final pitch out with smoke looked awesome.


Wings Almost Done ...Garrett Clemmer RV-7

I haven't updated this since my first post so why not now?! The tanks and top skins are installed on both wings and they are in the rolling cradle I built. Ailerons and Flaps are done. Just need to make the pushrods and install everything. I've got plenty of time until my Fuselage kit arrives as I'm not supposed to get it until early Fall. I think I'll probably leave the bottom skins off until later as I haven't decided on Avionics. I also need to insulate and get my garage all set up for moving the shop there as I am running out of room in my basement. It's been nice to build down there though as it's cool in the summer and heated in the winter. I'll just have to sweat it out in the garage during the summers for the rest of the build.

Trim Pushrod Issue

I have a question that I'm pretty sure I know the answer to.
When I match drilled the trim pushrod I was off a little which caused the rivet not to sit perfectly square. As you can see in the pic it caused the rivet to fold. When I went to set the 2nd rivet it started to do the same so I stopped. What would you recommend?


Leaky Oil Cooler

... it might be worth your time to do a quick leak check of the cooler. I had a failure at about 80 hours that was not observable other than a little oil at one fitting. I removed it to check/ replace the fitting and instead found a leak in the cooler.

Leaky oil cooler fitting

I'm 10 hours into my RV-14's Phase I, so it's time for the first oil change. While trying various methods to remove the Lycoming-over-torqued oil filter, I am also working on finding the source of the oil on my plane's belly. I have found oil seeping from what appears to be the lower/forward fitting on the oil cooler. Specifically it seems to be coming from where the 90-degree elbow is threaded into the oil cooler.

So, the question is this: Can I tighten that elbow 360 degrees where it sits, should I remove it first, or should I buy a new elbow altogether?

Spinner wear only at hub?

A nice crack popped up on my spinner, so I planned my standard fix of backing the area with some carbon fiber thread to strengthen it and fill on the top. Upon removal of the spinner, I found that the area right next to the leading edge of both FP prop hubs have an approximately two inch wear strip from the front bulkhead, as if the bulkhead is slightly oval in shape, with no wear anywhere else around the circle of the spinner. Seems kind of coincidental to have it on both sides, any particular reason for this?


Mothership News


Tailcone upper fairing scribe lines

Has anyone else come across scribe lines like this on the upper tailcone fairing? Click on pic to enlarge. And sorry, I'm not a photographer.

Response from Van's:

"I'm told the mold was re-scribed because the initial trim was too aggressive for some builders and you should use the more conservative trim lines, you can always remove more if needed."

That doesn't add up in my mind given that the double scribe lines overlap each other at the corners, are non-parallel in some areas, missing in other areas, final-trimmed to the scribe line in one area, etc. At any rate, the response implies that all of the parts shipped after the mold change look like this? My empennage kit was ordered 11/2019.

Lesson learned: I should have spent more time considering this issue before jumping in with the cutting tools. "I cut it twice and it's still too short!" Hopefully I can still make the part work and look good.

Rudder repair

Landed on the grass at 6S6 this weekend and the woop-dee-doos on landing roll out kicked the nose up causing a minor tail strike. The tail tie-down hook took most of the force but it did still cause a little damage to the fiberglass fairing and popped a rivet loose. My initial thought is to do a little fiberglass work to repair the fairing and install a new rivet as a temporary fix. There doesn't appear to be any internal structural damage, just limited to the skin and fairing. Maybe when I have a few weeks of time I don't want to be in the air later this year I can reskin and paint the rudder as the proper permanent solution. Thoughts?

BTW, I think I learned why people don't often take the -A on backcountry strips!

Big Weekend of Flying, 13 ship and Pearl Harbor ...ty1295

This weekend the Louisville Kentucky group (aka Smoke On Aviation) had a big weekend.

On Sunday a formation practice was scheduled out of KBAK (Columbus Indiana). Dave has been working with some local Bi-Plane guys on formation flying, how to follow FFI standards, etc. and this was a good chance for a checkup to see how they were doing. Close Intel showed they were doing great and a lot of hard work put in by them.

Yesterday the Smoke On group continued with flying and was about to be a small part of honoring Welborn Lee Ashby who was Killed on the USS West Virginia during the Pearl Harbor attack, with his remains only recently identified thru DNA in the last couple years. This weekend was the day they brought him back to his hometown and final resting spot.

RV-14 Canopy Frame Issue....

Having 3 days to work on my RV this weekend, I was looking forward to getting mass amounts of work done. Unfortunately, I ran into a snag on Friday evening that stopped my progress. I'm hoping that some of you can give me your thoughts.

Hopefully you can see the pictures below.

Rear canopy frame does not fit the roll bar.

The frame is .024 too short on top and .135 to wide on the lower corners.

When the canopy closes this will put stress on the top of the canopy
As the canopy frame descends from the 45-degree point, it gets wider. This will likely make the canopy wider than the rear window causing unsightly workmanship.
Other Info:
Upon finishing the frame, I was stunned how well it fit except for the rear frame assembly that is supposed to match up with the roll bar.

RV-12 empennage complete

I had first posted in September last year about me contemplating building an RV-12iS. I was also considering buying a built one or buying an old taildragger.

I wanted to follow-up and let you know that I decided to build and am LOVING it. I had a great time building so far, and was on track to complete the empennage kit in March. New baby came then, so my progress slowed for a while. Having 2 small kids makes building hard, but I've been able to make time for it.

This forum has been so helpful to see how others conquered various steps during the build and it's something I consult regularly.

I was a bit late ordering the wing kit, especially with all the COVID delays. It's supposed to crate the week of July 5th, but I am not expecting that timing based on seeing others' kits delayed past the quoted crate date.


Van's release of RV-12iS Skyview and G3X software/settings file updates ...Mothership

We have published new files for RV-12iS aircraft related to fuel pressure values and other configuration settings. There are updated files available (listed below) and README documents for G3X and Skyview systems.

In addition, these settings have been tested with Skyview v16 software. The Skyview software and settings package on the Van's Aircraft download page has been updated to include the v16 software. SV software v16 has been tested on both the RV-12iS and original RV-12.

The description of these changes is below.

Dynon AHRS and HUB question

Q: Can't get to the hangar to test this out right now, and trying to plan routing.  Does anyone know if the AHRS can be plugged into a dynon hub, and then the hub run to the HDX display? The way the Dynon wiring diagram shows it the AHRS is routed directly to the display serial port. It I can run to a hub it will simplify my wiring.

A: I hope so - I'm planning on that, too. I'm using AzGila's excellent hub kit, which includes the servo connectors.


How much dirt in our tanks is ok?

Hi Folks,

have no idea if there's a problem or not. fuel injected RV7 nearing 100 hours with standard tanks sealed with standard proseal and nothing else.

i religiously drain tanks as part of every preflight inspection. never found water, but anyway... what i find everytime is some dirt or debris in the drained fuel. what you see in the picture is the collected amount draining both tanks three or four times. when you look close there are some small dark pieces, some are more bright.

i have the airflow performance fuel pump spaghetti that contains a filter with a quite large filter area and a bypass valve.

i fuel the left tank with AVGAS from the airports pump for mainly takeoff and landing. the right tank gets premium grade fuel from the local gas station for cruise flight. when i fuel the tank from canisters i use a special fuel funnel with fine mesh filter.

is what you see ok or should something be done?

thank you very much in advance for your inputs.


My RV Weekend ...various


RV-8 and the Crater Lake

Saturday 5/29/21 was a spectacularly nice day. Spectacular in that is was exactly as forecast.

We took this opportunity to make a trip to Crater Lake, a trip we have wanted to do for some time now. The write up is linked below.

If you don't want to read the write up, the video link is at the bottom. If you don't want to watch the whole video, footage of the lake starts at 8:31.


RE: Aileron Trim Springs

BTW there is a bit of offset to the springs. If you mount them the wrong way they will rub against the pushrod.

My springs came with some of the loops being almost fully closed so getting them on the trim motor arm is not an option as is. I asked Van's my options on trimming and was told the red or yellow lines would be OK, this should make mounting a bit easier also.


Quick trip to South Dakota

Well school is out for the summer so now that I'm not teaching for a couple of months how better to spend time than with family and RV!

I decided to cross another state off the list. The weather was too awesome so I made a last minute decision and texted the wife that I was going to Belle Fourche SD.

First up, mountain crossing. I am almost completely surrounded by mountains so when I get the chance to get over them I try and take it! Luckily there is a couple of areas to get over them that still have some semblance of landing options.

First Flight ..dreed

Well, it finally happened.

After a bit of a stumbling block with the non functioning prop governor that took a couple weeks to get resolved, my plane is officially an "air"plane.

Mike Seager came over to Bend yesterday and took it up for its first flight. A few minor squawks, but for the most part she flew well. After addressing some aileron snatch and a overly low idle, Mike and I went up and for a little RV refresher training for me. I definitely need to sharpen those skills more still.

Still a few little things to address including some calibration issues on the passenger side EFIS, and adjusting the idle screw back down now, but mostly just need to work through phase 1 and get used to flying the plane.

A lot going on during my flight, but with no pants on we were seeing 155 TAS at 24/24 at 6500 (IIRC). All the temps looked great and engine seems to be happy so far. One thing that was a bit new to me was how much aero braking that big ol' Hartzell composite prop has when in fine pitch. Need to carry a lot more RPM once the blue knob is in than I am used to, but I've also been flying a fixed pitch 172 recently too so I am quite certain I have that muscle memory right now.

Lastly- Huge thanks to Mike Seager. For those of you needing transition training, or anyone like me who wasn't quite up to doing the first flight, there is absolutely none better than Mike. Truly a great guy to fly with and and absolute gentlemen who provides so much more knowledge than just the flight training side. Mike was quick to help us tweak the ailerons and elevator after that first flight.


RV-9A: Cal's Build ...Garmin module fitting pics


Rv-4 Firewall component installation

Q:  Hello everyone. I am ready to begin installing all of the accessories attached to the RV-4 firewall. Brake reservoir, solenoids, battery (maybe), etc. I will have horizontal fuel injection and a constant speed prop. A photo of a layout would be very helpful. Thank you in advance for permitting me to benefit from your labors.

A: A couple things
The -4 is a bit of a challenge due to size and various configurations. Certain things must be in proper orientation. First concern is engine control cable routing and pass throughs. For my carbureted O-320, they come out through the tunnel low and near centerline. Cabin heat, depending on your plan for that has to be routed with ducting from the heat muff. Your oil cooler location can also impact what can be behind it. Here are a couple pics of mine, though not prefect, have worked well so far. My battery is in the tunnel, but I have room to go on right side of firewall if I want. My heat box is on L/H side, but muff is on R/H pipes, so SCAT tube runs around back. My pressure sender manifold is on L/H upper side. The brake reservoir needs to stay centerline and high. Fuel line and smoke system lines are in tunnel down low. Both solenoids are in tunnel on cabin side and out of the way. Really need engine hung to know some things or face relocating them later. Plan carefully, cut/drill once!


Cleaning the Spray Gun Pays Dividends ...some PIREPS

- You ne if you were not already doing so, need to unscrew the cap and take the nozzle out that the cap holds on and clean it very thoroughly. DeVilbiss finish line 4 is a quality gun for under a couple hundred bucks. Paint is very expensive. And the effort it takes to reprep a surface is frustrating to say the least. I would spend the money and get a quality gun.

- Disassemble and thoroughly clean the gun every session. Stuff builds up in the tip real fast. I neglected itba session or two and removed a big doughnut shaped wad 1/8" thick. It should be nice and shiny inside. Check the needle. Check the nozzle too. Lots of tiny holes to direct the fan. They all need to be clear or the fan will spray crooked.
I really like my DeVilbiss FLG, but today I bought a Harbor Fright Black Widow HTE. Dang thing is a work of art. Can't wait to try it. It's a copy of the SATA 5000 ($999) gun.

- Last, use a quality regulator at the gun. Inuse an RTI Mini 1/4". Hose from compressor feediing the air/oil separator then regulator at the gun.

Please tell me this part is ruined so I can move on

I think I really did it this time. This is the trailing edge of my rudder. I popped that extra hole in there accidentally. Maybe time for new glasses.

I tried expanding the proper hole to a #30 and re-dimpled to see how it would look but obviously it did not help. I'm about to order a new skin, unless there is some method of saving this one to which I am unaware.

Thanks for the insight as always


Trim Cables - Not for Use on Aircraft

I did a search before posting this but didn't find anything. It was a little disconcerting to learn that the trim cables were "Not for use on Aircraft." I suspect I know the answer to this, but have they always had that disclaimer? Has anyone used something else?


Roman Capital Letters

Actually just finished my N number. I purchased the Cricut Air 2 and tried several vinyls before settling on oracal brand (sourced from Michaels). The Cricut comes with software to make just about anything for their cutting machine. You can even install new fonts which is what I did. I used Amarillo USAF font I found on-line for my A-10 themed RV-8a. As a side note, I tried using 3M car wrap vinyl but had trouble getting the transfer paper to stick to it. I used it on the tail flash but would probably stick with Oracal going forward. There are 2 types of Oracal vinyl. Get the "permanent" and not the "replaceable". Good luck.


NE US Coastal trip

CS Pilot size

I was working on my -10 VS last night and got to a step where I needed to drill a #19 hole and countersink for a #8 bolt. I bought my tool set from Cleveland so I got my #8 CS and the pilot would not fit into the hole. I fiddles with it for a while and looked up the CS on Cleveland's web site. They state "CC8 - #19 drill size for #8 or 8-32 screw - Pilot size 0.166". I measured the pilot on MY CS and it was .197 . Could be a manufacturing error but was curious if anyone else has run into an issue like this. If it was a Mfg error I'd be surprised if I have the only bad one. For all I know it is something I am doing wrong.

I contacted Cleveland and waiting for a response but wanted to ping the group.

R-716 Fairing Attachment at the bottom of the rudder.

Made my first glaring mistake on the plane that I'm not sure how to fix. I'm working on the rudder and has to fabricate the R-716 rudder bottom attach strips. Well I measured wrong and they are about two inches too short. The problem is I don't have enough material left to fabricate new ones of the right length. I know I can order more, but looking at what these attach strips do, I think I can make it work. I cut the fabricated ones so that the end fell between two rivets and cut an additional piece to fill in the difference. Pics are attached. I need to deburr and clean it up, but the idea is circled in the pic.

Asking the more experienced Vans community....Do you agree with my assessment?


Old School Behind the Panel

Claudio's in Italy.  Beautiful. 
"My panel is old and simple.  The panel is wired only via connectors, it is easy to remove it from the plane.  Autopilot servo, power and signal relais, motor sensors, two AHRS ( located in the central tunnel ) and e-compass are installed were convenient.  The black panel with the tank selector can host an extra volume of two Garmin 328.  Open" inst.panel " on the link below for pics."



Dragging brake (RV-12)

I finally got around to troubleshooting a dragging brake problem I've had from the beginning. This was an interesting one..

The symptom was that the plane would pull to one side pretty hard regardless of how much engine torque was applied. I got the plane up on two horses. One wheel would rotate relatively freely (like 1 or two fingers on the wheel could provide enough force to make it rotate), while the other would have a dragging brake (you need your entire hand on the wheel to give it enough force to rotate). The problem existed for only half of the rotation.. NOT throughout the entire rotation of the wheel.

I dug out my runout gauge and found that the good wheel/rotor had 0.005" runout, while the "bad" wheel/rotor had 0.030" of runout. I disassembled the wheel halves thinking perhaps I had a bit of debris that got sandwiched between something during assembly. Everything was clean.

I mounted the wheel's center hub/bearings and its rotor to the plane's axle. The problem still existed. I swapped rotors between the two wheels (attempt to confirm or rule out the rotor itself). The problem followed the wheel, not the rotor. I examined the wheel's center hub.. and found the issue. Apparently one of the three "spokes" of the center hub was machined down exactly 0.020" too much. I sandwiched a feeler gauge between the hub and rotor and re-measured the runout.. which was now 0.004". (see photo)

I usually attack problems as "what did I do wrong this time?" rather than a manufacturing problem.. so it took me a long time to get down to the root cause of the issue. I have a call out to Matco, but for now, the shim is working very good with greatly improved ground handling. The next time I put the plane up on horses, I'll most likely replace the hub (about $50 new from Matco)

My RV Weekend


Torque tube sub assembly

I had to leave the shop the other day with this task left unattended. I performed the final torque on ends of the subassembly torque tubes for the right wing without needing any adjustments.

Moving to the left wing, I final torqued one side the. Moved to other. When I did the final torque, the bolt had a little over 1 thread showing, and it needed at least 3 to 5 threads . I didn't check the opposing bolt, due to time constraints.

Since the lateral dimension of the subassembly is fixed per the plans at 17 3/4" to 17 25/32", I'm hopeful that I can loosen one nut and tighten the other, attaining the requisite threads exposed for both sides.

I won't return to the shop til Tuesday, but I'm hoping this is a quick fix and loosening one end while tightening the other works out.

Any thoughts? Thanks. Jt


Time to address that dang valve cover...

,,,that does not fit in the cowl. (AX-O)


HS00005 rub, help!

So after assembling/dissembling (x10) the HS00005 rib to the aft side of the front spar. I riveted them into place. I thought I had fixed the issue of HS 00005 rib rubbing on the shop head of the extremely close adjacent rivets(outboard) but alas 2 are ever so slightly rubbing the 00005 rib. So my question is, what should I do to rectify this rub, surely I can't just leave it and call it good? Is a dab of rtv an acceptable fix? Is drilling out and flipping the heads of the 470 rivet a fix?


Rear Seat Lap Belt Bracket Corrosion

I decided to remove my rear seat belts for thorough cleaning after an unfortunate barfing incident while giving a Young Eagles ride...

When I removed the lap belt from the side attach points I discovered surface rust on the brackets as depicted in the attached pictures. I removed the brackets and plan to take a wire wheel to them, then prime and paint them to prevent further rust. I have a few questions I wanted to run by the forum, as I am handy, but not a builder, nor A&P, and these are what I would deem safety-critical pieces of hardware.

1) Is removing the surface rust with a wire wheel, painting, re-installing, and putting back into service a perfectly safe and acceptable practice?

2) What would cause rust like this? There isn't a speck of rust anywhere else on the airplane. Could it be a case of incompatible metals?

3) Shouldn't this kind of thing be caught at every Condition Inspection? Maybe it was observed last time but I'm over reacting...?

I have Hooker Harnesses if it makes any difference.

Thanks for the insight!

RV-8 and the Great Weekend ...Steve Rush video

This past weekend was one of the best we've had so far this year in the upper left hand corner. The rain stopped (briefly), the clouds parted (briefly) and the temperature warmed enough to put the parka away for a few days.

Saturday we made it out to Forks for lunch, hadn't been able to do that so far this year. It was a really nice trip.

Sunday I wanted to go check on the Elma airport (84WA) that was recently permanently closed. I wondered if they had dug up the runway or anything. It is still there, in about the same condition, but the "X"s marking it as closed are really hard to see from the air.


Bench Wiring Calling Done

Well today I am calling done the bench wiring of the Panel and Sub-panel. I cant think of anything else I can do on the bench before installing it and hooking everything up to the stuff already wired in the plane.

Here are the pics on the bench of all the stuff. There is really a lot of boxes and wiring in this panel. It didn't look so bad when viewing the schematic several months ago.

I can't light it up without the antennas hooked up, so I will just pretend that is is wired correctly.

I have been neglecting the fuselage wiring; so now it is time to clean that up, and get all the fuselage foot well stuff done prior to putting in this panel structure.

In other news, coming up on 5 years. Really hope to be done this year. Hope it is all downhill from here (panel wiring done).


Do tanks need to be drained for fuel selector maintenance?

I have an old brass 3 port fuel selector on my plane and the handle seems quite stiff; partially due to location but it has recently taken two hands to turn in flight. Obviously this is not acceptable.

I found a schematic in the archives and plan to disassemble and lube it, but before I do, do I need to drain the tanks? This is for a taildragger, if that makes a difference.


Panel picture request

(Q) Can anyone please post picture(s) of the current RV-12iS panel with the Garmin IFR package installed per Van's instructions... no modifications.



Skybolt cowl fastener issue

Maybe I'm missing something obvious so I hope you guys can help. Getting ready to install the sky bolt receptacles and I just don't understand the design. The rivets that hold the receptacle to the flange need to be flush, so I dimpled the flanges. If I don't dimple the receptacle there's obviously a gap. If I disassemble the receptacle and dimple it, then the barrel doesn't fit without grinding. So what's the right way to do this? I can either have a gap and a weak connection to the flange, or spend the next few weeks modifying the fasteners to fix an obvious design flaw?

Edit: the receptacle is .030" thick, so countersinking isnt an option.

Bobby Hester's Alternator Replacement ....last year on his website (I missed it before - sorry)

Saturday - June 13, 2020
Well today was an eventful day. The plan was to take off at 5:30am pick up a fellow pilot in Dickson, TN and then we were going to fly to Delaware, OH to do a Pre-buy inspection on an RV7 aircraft that he was going to buy if the inspection checked out ok. Everything was going well until my roll servo kicked off, this happened one other time and I was supposed to remember what that was an indication of, the last time that it happened it was because I accidently turned my master switch on to the battery position rather than all the way up to the Alt position. When the battery voltage starts getting low the first indication is my roll servo,  --->


How much RPM gain would I get from upgrading to PR wheel pants?

As the title implies, I have a fully faired airplane but with the old one-piece wheel pants and the two-piece aluminum leg fairings. I recently purchased a second hand three blade Catto and found it to be rather cruise pitched for my plane - my static RPM is approximately 2090, and it winds up to 2150 in the takeoff roll. My WOT RPM at 7500' is 2640.

In speaking with Nicole, it seems I could benefit from a repitch for more static and climb out RPM. In the process of this, I inquired if the additional airspeed from the newer wheel pant design would make up any of the difference; she wasn't sure.

So that's my question. Will upgrading my wheel pants let my prop spin up to the magic 2700 RPM as currently pitched? Similarly, while it obviously wouldn't affect static, would the takeoff run and climb RPM be improved at the same airspeed? If yes, may it prove sufficient or is the static RPM still just a tad too low?

For reference, the prop is a May 2016 production (I'm not sure if that's second or third gen.) on a 150 HP RV-4.


RS 232 out signal

Is there a way to check for or confirm with a meter, an RS 232 out signal from a device such as a GNS 430? I know how to get into the configuration pages and change the settings. But how do I verify the signal is actually being transmitted? It's going to an Artex 345, 406 MHz, ELT. Thanks!

You can build a simple LED test light to see if your RS232 port is operating. The attached image is from the ACK ELT installation manual and should work with any RS232 port. I built the test light and an on/off switch into my panel next to the ACK ELT remote so I can periodically check the RS232 operation.


How do I disconnect this circular connector?

The PTT switch on my Infinity Stick grip has become unreliable and needs to be replaced. From what I've read on other posts it seems wise to remove it from the airplane to do the disassembly and re-assembly.

The stick wiring appears to be terminated in a standard circular connector to the left of the stick base, but I can't manage to disconnect it.

Any hints? I'm not sure if I'm doing it incorrectly or it's been cemented together with some sort of thread locker.

What's been your biggest preflight surprise?

1. Yesterday was the first flight after a month-long condition inspection. It was great to be in the RV-9A again, to refresh the memory on the avioncis and instrument procedures, etc. The interior had been cleaned, I was glad to be in the air.

This morning was to be an Instrument Proficiency Check in preparation for a ten day trip one state shy of coast to coast, and of course, I did a preflight. Hey, everything was fine yesterday, but let's do the preflight, just because.

Hmm, the right wheel pant is almost touching the hangar floor. Low rider? Nope, just one very flat tire, probably a leaking inner tube. Fortunately the plane wasn't resting on the wheel pant. And if the tire went down that much overnight, probably don't want to fly the plane today.   continue

Spark plug blowout after Takeoff

Wondering if anyone else has had this issue. To be fair I have not contacted Emagair as of yet. We replace our auto spark plugs at every condition inspection and reuse the short reach adapters.

We have about 4 hours on the plane since the inspection. Taking off on runway 07 I made an aggressive low level turn to crosswind and was climbing thru 300 ft Agl when we heard a loud bang and rough running engine. We immediately told the tower we were returning and landed on runway 25 twenty knots fast in airspeed and with 15 knots on the tail. All worked out OK. The analyzer told us the issue was with number 4.

When we pulled to top cowl the problem was obvious - the plug and short reach adapter were hanging by the lead. Further examination showed that 75% of the first three threads of the adapter were missing.

Has anyone had this same experience ? We of course blamed ourselves thinking we missed torquing the number four assembly but I am questioning that now. Due to the cost of the adapters, 100 bucks for 4 we have been reusing them. We are now thinking about replacing them at every other annual.

Thoughts ?

Formation training

Flew formation training with the B2Osh guys. The Beechcraft guys graciously accepted me into their formation training course this weekend. Good times



(PIREP from Scott @ Mothership)

"Clecos are not high precision devices when it comes to aligning holes.

One technique that can help is to use a #30 alignment tool inserted in a hole adjacent to where a cleco is being installed, to help get precise alignment before the skin is clamped by the cleco.

You can make a tool from a dull #30 drill bit.
Sharpen a point on the end that normally inserts into the drill chuck with a grinder and then press the drill bit into a dowel with a hole drilled in it to make a handle.

An additional factor in hole alignment at assembly is the level of precision when fluting flanges on bulkheads and ribs to straighten them. If not done thoroughly, you will always be fighting to get holes into alignment.

I would not recommend using a #29 drill to ream the holes."


Waxing your RV

I use Meguiars Ultimate Quick Detailer after the flight to remove bugs with a clean microfiber towel. I do not have many hours yet but the paint still looks great.


What's My Next RV

I don't post often, and for that I'm sorry - I just haven't had a lot to contribute in the last few decades. I'm thinking that I want to build another RV, but I'm not sure of the direction I want to take. A little background is in order...

I started building my RV-6 in 1989 when I was just 26 years old. Four years later I made the first flight. The airplane was a significant expense to this young lad, so I picked up a partner just before the airplane was finished. That turned out to be a mistake. The partner was clumsy and careless - I often found damage on the aircraft. The straw that broke this camels back was the day I showed up to fly my plane and the G-Meter was pegged at 6+ G's. In 2001 I couldn't afford to buy the partner out, so I sold him my half. It was gut-wrenching, like selling a child, but it was the right thing to do at the time. I had a young family and I seemed to have less and less time to fly, and when I did find time to fly I was disgusted at what I'd find. Luckily I had access to a B33 that my company owned at the time, but after flying an RV for 500 hours - I just couldn't connect with that pig and in 2003 I decided I'd just stop flying.

It's been eating away at me for 20 years, so yesterday I went for a BFR - and to my surprise I remembered how to fly. I have a fresh endorsement in my logbook and a desire to get involved again. But flying the Cherokee 140 reminded me how uninteresting Piper/Cessna/Beech aircraft are. In the last 20 years I've thought about building another aircraft dozens - hundreds - of times but now it is something I can seriously consider again. And just like 30+ years ago when I decided to build an RV-6, it comes down to "what's your mission profile". Back then it was x-country/transportation, sportsman aerobatics and light IFR. Now, it may not be any of those with the exception of some x-country flights. My wife doesn't like to fly, and that limits the amount of travel I'd do in the airplane. I'd be flying mostly for my own enjoyment, taking friends for local flights. Travel would probably be limited to 100-200 mile trips to see family. But I'm just addicted to the control feel of an RV-6 (I also have quite a bit of time in the -4).

For the mission profile I've provided the RV-12 certainly makes sense. I also like the fact that the wings can be easily removed if winter storage at home is possible. My concerns with the -12 are its "total performance" and control feel. Also, I really enjoy aircraft with conventional gear. It's a skill-set that I'm proud of and I believe it makes me perform as a better pilot (like a manual transmission in a car).

I think the RV-9 is also an aircraft that meets the needs of my use case. While the control feel is just slightly less responsive than what I enjoyed in my -6, for the way I intend to use the aircraft the control feel just may be perfect.

Lastly, the natural successor to the -6 - the RV-7 - would certainly make me happy. But it seems to me I'd be heading down the "make it better-powerful-faster" rabbit hole. That project may turn out to be too expensive.

Another piece of info that may make this choice interesting. The gentleman who purchased my RV-6 from me, would like to give (not sell) it back to me. For the same reasons I sold it 20 years ago, I would not fly that aircraft today (I have not seen it since the day I sold it, but I'm told by friends that it's in rough condition). But I could scavenge it for parts. The engine is due for an o/h (O-320) but that is a better option then buying new or buying a core for o/h. I don't think I'd use the prop, but items such as the exhaust, autopilot (Navaid Devices), elevator trim, lighting, circuit breakers, switches...could be reused. I don't think the instruments are of any value (I'd go glass) nor are the Narco Avionics. The other option is I could bring the old girl home and re-build her - but that may be more work then starting from scratch. I wouldn't know until it was in pieces. I like the idea of building another, but dread fiberglass work and building another canopy....

Enough background. Have any of you other RV old timers built a second RV and did so because your original RV no longer met your needs, or it was just time to build another? If any of you built a -12 or -9, how do they fly compared to a -6? Can you help talk me into, or out of this endeavor?

While not strictly RV, the pilot of FIFI in this clip flies an RV-8.   They were giving rides out of Meachum on Saturday and their groundtrack passed nearby.  I had 20 minutes notice so had the video rolling.  What a privalage to get to see this aircraft in flight.

#1 cylinder EGT high on takeoff

I have an I0360 with Airflow Performance fuel injectors that have been calibrated. Now have 300 hours and all has run perfectly up until a few hours ago I started to notice in the yellow on #1 on takeoff. I have since inspected and cleaned all injectors. There was no obstruction or debris. After test flight, #1 in the red but would come back in yellow and green when I reduced throttle. I then disconnected all injection line, used 4 baby food jars, initiated boost pump and all fuel collections were identical. Next swapped Alcor 86255 EGT probes between #1 & 3 and test flew again. #3 registered high and I then installed a new probe in #1 and reinstalled #3 back in #3. Test flew and #1 registered in the red on takeoff, would come down to yellow and green on throttle reduction.

Please let me know other suggestions to check. I generally run LOP and the EGTs are within 10* between high and low and CHTs are very close also (#4 highest where oil cooler is located). I have two PMags and they have been flawless to date. Engine has really run very smooth, starts easy cold or hot. Thanks.


Reported on the Mothership


Refinished roll bar

Here is the refinished roll bar after stripping back to bare metal and then priming and topcoating with Rustoleum. I'm happy enough with how it turned out and will use the same process on the canopy frame. I checked the outside dimensions of the roll bar versus the fuselage side longerons and the bar is about 1/8" too wide, so it will need to be tweaked with a hydraulic press before fitting. I can easily touch up the finish if needed.

What is this black stuff around my tank access cover?

I'm desloshing my '91 RV-4 tanks and the access covers had cork gaskets. I plan to seal the cover plate with proseal only.

I'm wondering what the black stuff is on the outside edge of the doubler for the cover plate? It is soft. Is it old proseal that broke down or something else? Should I try and remove it and put a ring of proseal around the outside edge of the doubler ring?


David Paule RV-3B Status Updatre ...many pics

""...A neighbor has an RV-3. He dropped by to show his friend my project. She's trying out the Confor foam I got because I was tired of sitting on hard pink construction foam. There's still no lumbar support; the back cushion is still pink construction foam."


Unexpected break from building

I haven't posted any updates for a while because after riveting on the rear fuselage skins I was diagnosed with cancer and advised to have surgery within 3 months. Following surgery there is a six week recovery period with NO LIFTING, which is almost impossible on a farm, so the RV project had to go on hold to allow some other heavy jobs to get done while still able. I covered over the fuselage and put away the tools... frustrating.

Now in the later stages of recovery I've found some light jobs that don't require any lifting, though somebody needs to open the shop door for me!

A few of the steel parts, including the roll bar and canopy frame, came from the factory with powder coating. Altough the parts were stored inside the workshop, there was corrosion coming through and spreading under the coating, particularly where any dust had settled. I've been removing the powder coating with paint stripper and sanding off the corrosion. I intend to thorougly clean the metal and apply an appropriate primer and topcoat to protect it properly.


What would you do....?

Okay, an engine found its way into my hangar (all legal!)

What i know:
-O-470 with all accessories
-not run in 15 years
-not pickeled for long time storage
-lay in the corner of the hangar (not climatized) 100 miles from the coast
-came of Cessna 182 crash landing, engine quit during decent after para-drop.
-engine turns easily by hand
-cylinder walls are corroded

What i don't know:
-whether the engine was running or not on impact (shockloading?)
-exact engine designation
-history prior incident

-is there a market for this engine?

I don't have the paperwork.

What i plan on doing:
-check whether the crankshaft ist straight or not
-decide from result if rebuild is worth it or sell parts individually.


Slider assist

I think my slider fits too good. It takes quite a bit of pulling and cussing to get it started sliding away from fully closed. There's very little leverage yanking on the top handle. I have to lift on the edge of the skirt. That's not a good long term solution. Ive seen one or two with a little clip near the aft end to lift. I need something to lift and pull aft. A car door handle shape is ideal.
I am thinking about adding a piece of angle aluminum as a lifting tab in the area circled in red. I can back drill through the C791 Canopy Skirt Brace and rivet the handle to it, using three or four holes, so it has some structure. One each side, powder coated to match.
I don't want to drill the top bow. There's no holes in my canopy. Well there's one for the latch.
Does anyone have better ideas?


Mounting and Wiring LSE Coils

I am big fan of the Lightspeed Plasma III system. This is the third aircraft I've installed these on, and flown 1000+ hours without issue (...jinx...)

However, there are certain parts of the system installation that I found to be sub-par:

1. Soldered on D-sub connectors.
2. Old systems - weird non-milspec wire from the flywheel sensor.
3. Cute but not useful mounts for the coils
4. #@!&* RG-400 for the primary wire leads.


#1 is easy to solve - cut off and use crimped-machined D-sub contacts
#2 replace wire with MIL-STD 27500, 20 ~ 22 Ga wire.
See attached for #3 & 4.

...and yes, adapting 2+Shield wire to a BNC connector isn't approved, but you can make it work and it's solid as heck.


Doing a thing...

Weird to me that CO is "Midwest" - but OK.. ;-)

Panel Porn

This my new -10 panel built and installed by Avionics Systems. David Buckwalter and his team worked with me to do another beautiful panel (they also did my -9 panel a few years ago. With the latest and greatest from Garmin, finished in double stitched leather and carbon fiber, it is just what I was looking for, really happy with it. I expect to be finish building and first flight by late this fall.

RV Excitement -vs- 172

Bit of a backstory. I met my now wife, shortly before I bought my now flying RV9a as a project. At the time she had this unspoken word of "No way am I flying in that thing when you get it done". Fast forward to a year and a half ago when I got airworthy ticket, her 1st flight was a short one on a cold day. 2nd flight was 3 hours. After that flight she decided to get her license.

Since then she has been either instructed in or a passenger in a lot of RV activies, cross country flights, formation, aerobatics (in RV8), etc and been very excited. Her first 28 hours of student time was in the RV9A, and we recently switched to the 172 in order for her to get more consistent training and it opens up instructor time. Her written in done.

So 5 Hours in on the 172 and she has come to realize she hates that airplane, and once her PPL test is done if she never fly's in one again it will be too soon. It got me to thinking, how many people get introduced to aviation via a similar trainer and never come back for the same reasons?

Had the 172 been her first experiences she would never have been this excited.

Teflon Hose Reply

(TS)  Sorry about the pic-----but it does show the OE hoses that Vans had on the RV12. Stratoflex 124 with 524 and 528 stainless hoses ends. Note the stamped AN nuts. The Rotax provided hoses were rubber lined pushlock hoses like the second pic. Steel fitting, some were metric threads with DIN ball seat connections. To my knowledge, Vans always used teflon for the oil system. Early on, Rotax supplied the fuel system, which was rubber pushlock under the firesleeve--hence the 5 year replacement SB. All have since changed to teflon.
TS Flightlines, Aircraft Specialty, and now AS Flightlines Joint Venture has always used teflon.

If anyone has trouble identifying what they have---give us a call.
AND---dont get fooled by a data tag on the firesleeve on an obvious old hose. Yep, its been done that some guys removed the firesleeve and data tag and reinstalled it on 'other' hoses. And, just because you pull the firesleeve back and it has a stainless braid hose underneath, it 'could' be a 701/156 style hose with a rubber liner, or an imposter hose that is a lookalike 701/156 hose from one of the race car hose suppliers. Teflon hose, if not damaged by rubbing on something will outlast the life of the airframe.


RV Model Comparison Table Updated

"..ok guys, the table has been updated. Vans aircraft filled some of the blanks I had, and I did some interpolation on some of the data.
Also added the MPG fields (thanks for the idea Paul), the different power versions of each model, and some.

Now you can brag about your ship being the quickest, most economical, etc... well, in theory that is"


Help us test our new web store ...mothership

We all know that the current Van's Aircraft online store is - well - let's just call it lacking. We've been working on a complete store replacement and are getting close to go-live planning.

While there are still a few features to complete and a list of bugs/issues to eradicate, the end of the project is in sight.

Anyone who is interested in participating in our formal testing effort is welcome to send me an email (media@vansaircraft.com) to let me know. We have a handful of customers who have already tested (and are continuing to do so) and would welcome a few more as we continue to make changes and as we get closer to our initial release.

So - if you're interested in setting aside some time for testing and providing feedback, please let me know! I only ask that those who volunteer be willing to actively use the site and provide the feedback we need to make this project successful in the end (so there's some commitment and it's not a general access invitation for people who are merely curious - that phase will come later). For those who help us reach the finish line, I'll be sure to send some form of "thank you" gift when all is said and done, of course!

Houston area monthly lunch (May 2021)

OK, we're going to try something new thing month, specifically a new and more fly-in friendly venue. This time we'll hold court at the Runway Cafe at KLBX. Time will be the usual 11:30, this Saturday, 5-15.


Since this is a hefty drive from Houston proper, I'd like to try and get some airplane-pooling going to encourage attendance. If you're able to fly and take passengers, please post here with your departure point/time and who you can carry. If you're looking for a ride, post that here too and we'll work on getting passengers and pilots paired up.

To get us started, I'll be flying down in a rented Arrow out of KTME, probably aiming to depart around 10:30. I can manage about 400 pounds of passengers, so probably two adults in practice unless there are some skinny folks I haven't yet met.

Additionally, this is predicated on me getting my flight review done Thursday, because I am really good at procrastinating... Don't have any reason to think it won't happen, but Murphy can be really obnoxious.

Wide Foot / Feet Getting stuck on Rudder Pedals

Hello All

Couldn't find anything with the search function. When it comes time to steer or use the pedals at all, my feet are so wide that they get caught inside the pedals and when I try to pick my feet off the pedals or move them up and down, the pedals come with my feet or won't let me slide up or down. Any thoughts? Narrow shoes hurt my feet.

Mothership News


Parking Brake Install PIREP

just as a follow-up, I finally got around to installing the Matco parking brake valve. Fairly straightforward with the 2 additional Aircraft Specialty hoses and works great.

A nice benefit is that you can jump start the airplane. set the parking brake and get out to disconnect the cables without shutting off the engine or asking someone else to endanger themselves close to the prop. The PB holds the airplane up to a static rpm of around 2400


Chasing a vibration at cruise RPMs.

BLUF: I have a vibration I hear and really feel in my feet when the RPM is above approximately 2450 RPM.

My RV-4 has a slightly over pitched 3 blade Catto on my 150 hp O-320. The prop is on a 4" Saber extension and has a 20 pound crush plate on the front; I'm using a 12" Catto spinner with the front bulkhead removed to accommodate the large crush plate (the crush plate touches the inside of the spinner and provides a bearing surface). I recently had the a dynamic balancing performed and for full throttle static conditions, the results were great - I started at 0.454 IPS and we got it down to 0.005 IPS on the third iteration. In flight however, I still feel a vibration above 2450 RPM up to the max RPM I can achieve. I emailed Catto and Nicole recommended trying to reclock the propeller 1 or 2 bolt holes. I reclocked one hole (60 degrees) CCW (looking at the tail) and also checked the tip tracking when I did so (it was within Catto's 1/8" tolerance). I left the balance weights in place and flew for an hour, and still had the high RPM vibration. When I landed I took the prop back off and reclocked it another 60 degrees CCW (120 degrees total); I haven't test flown this configuration yet.

Why am I posting this in engines instead of propellers? Based on all the above, I believe the prop can be ruled out as the cause unless this latest reclock proves to be the silver bullet. I downloaded the EMS data and reviewed the traces - I didn't see the signatures of either a bad exhaust valve or a pair of cylinders down on power from a cam/intake issue.

I want to think it's something on the engine that I haven't considered causing this, although I'm not able to positively rule out something on the airframe. I did check the obvious (loose fairings) and in the past such defects manifested as a high frequency audible buzzing rather than a low airframe rumble.

I'd very much appreciate any insight on where to look next, especially if this latest reclock isn't the solution.


Firewall as a Ground?

Ok, now that We've established A good place to ground the engine case, what about the firewall ground? I don't have a dedicated ground bar on the firewall. Mine is grounded on the engine mount, which was decided to be less than ideal.

What about using the rudder pedal anchor point?


Possible Prop Gov Solution

I'm not saying this is your problem...but;

A friend of mine building a -14A recently installed his IO-390 and propellor governor and he asked me to look at it.

I noticed that he inadvertently left the pad cover seal in place when he removed the cover and "doubled up" when he installed the prop. governor.

Fitting Plexiglass Bubble to Canopy Frame

(fixnflyguy) What I did....I cut my bow at the centerline and removed a little bit at at a time until the canopy bubble fit down over it. I then got a piece of tubing (3" or so long) that fit inside of it, curved it to match and and installed it with a few pop rivets and epoxy. Welding is also a "normal" operation as its 6061 and very weldable. I simply didn't want to haul it off to weld it. The canopy is the hardest part of building a -4! Can't really see in these pics, but I can take some when I'm down at the hangar..The side skins are the next challenge once you get the frame/bubble fitted. Lots of dynamics here that need much pondering before drilling and riveting!


RV-14A Nose Wheel Fairing Detachment on Landing


Has anyone had the same experience as me.

RV14 Nose Wheel Fairing Detachment on Landing.

I am in the process of flight testing covering the test schedules of the LAA (light Aircraft Association) in the UK and on landing after only 6 hours of flying the nose wheel fairing detached.

I have attached photos of the damage. I have re-assembled the parts with one layer of glass fibre on the fractured edges to try to establish the cause of the problem.

An idea is that the 8 countersunk screws are not sufficient to hold the Fairing to the Fairing Bracket. Also the large OD diameter of the washer within the Fork Nose axle bolt assembly (Washer 062 25783054) (Page 40A-07) the OD is too small.

Any suggestions of possible causes would be welcome.

Regards John


STEM Aviation Event

This past weekend there was a aviation expo put on by the Ascension STEM
Group and Louisiana Regional Airport, KREG.
It was a huge success, with over 500 that RSVPed and many walk ons.
We had eleven categories of aircraft for the people to view. They went from
WWII to modern jets.
Pearl, my RV-9A, represented the Experimental Category. Parked on one side of Pearl was a Navion and a J3 Cub on the other, with a Stearman on the end.
The Air Force, Air National Guard, CAP and State organizations were present.
They had activities and prizes for the little kids and lots of airplanes for the big kids.
This weekend was also the monthly fly-in/fish fry for EAA chapter 244. So it was a super busy time at the airport and a giant success. Lots of RV's also
flew in for the monthly fly-in.
Plane owners were busy the entire 4 hours, 10am-2pm, answering questions
about their aircraft from the folks walking down the flightline of planes.
This was the 1st of this event with STEM and KREG and before everyone left it was agreed/approved for next year.
Great time had by all.

A Tale of Two Squiggles

One is mowing the yard Saturday, the other flying the RV.  Doesn't one look a lot more relaxing?



May 10, 2021.  Issue #5,337.
  Hope you had a nice RV weekend.  I flew the 'ol RV-6 (track) for the first time in I think three weeks, and it felt wonderful.  Light rain kept the bugs off and the canopy clean.  Part time sim side work keeping free time at a big fat zero lately - 17 clients in the last 15 days.  Sidenote....are there any readers that work at HP or Dell or any of the major PC companies that I can get some recommendations from?  I need a new Windows PC, tech changes too fast for my brain to follow, and free time to research is something I don't have a lot of these days.  My current rig is a little long in the tooth and acting up now enough to concern me.  I'm down to a laptop and would feel better if I had a solid desktop addition for the main grunt content dev work.
  Back in the day I enjoyed computers.  Those days have passed <grin>.  I miss DOS 2.2.

Barbara's first flight

This was in July, 2019, just days before her flight to Oshkosh with me. Now she is weeks away from her PPL Check Ride, and trips in my RV-14 provided the impetus. So proud of her, and she still gets "the grin" every flight with me. She's learning out of KGAI, inside the DC SFRA.


The Phoenix has risen! ...gyoung

My RV-6 project, dubbed The Phoenix Project, took to the skies today. Those of you that have been around here for a while may get the reference as a rebirth of my first RV from its 2001 accident. In 2002 I used the insurance proceeds to buy the salvage, a partially completed kit and a flying Navion. I've spent the last 18+ years chipping away at the RV while flying the heck out of the Navion. I licensed it as a new airplane but kept the N-number (N6GY) and reused the vertical stab, canopy, engine and radio stack. The AWC was issued Feb.9 and I have been slowly tweaking and checking off boxes until today. After so long it's still hard to grasp but I am so looking forward to this new chapter in my life.


Shimmy, not what you think

RV6A, very nice airplane that we have maintained and flew about 150 hrs. a year for the last 9 years. We have not had any problems but a main gear shimmy that seemed to go away except for 22 to 23 knots, no matter what tire pressure we used and we always balanced the tires. At the condition inspection last month we replaced the tire and tube on the left side. We just touched one of the four nuts holding the axle on with a wrench and it moved. They were lock nuts, but they were not tight. All four were about a quarter turn from proper torque. Four flights now and no shimmy at all, at any speed. CHECK THOSE NUTS.

Ashland, OR S03 RV-7

Came across this very nice, minty green RV-7 at Ashland Muni in Southern OR in April of 2021. Surprised it was not in a hangar, but out on the tarmac. Beautifully crafted plane!


Pride & joy

Just sharing. This was flight #2, so you' ll understand.  99% done, about 99% to go..;-)


Shipping Alternative

With the disruption of just about every business caused by COVID-19, I would be inclined to schedule a week free of anything else and make a road trip to do the transport myself. A trailer with some careful planning will get the job done. My RV-9A was just over 1000 miles away. It took 3 days. First day to drive there, second day to load, third day to drive home and unload. Wings and HS along with a few other things are in the wooden crate under the fuselage. The van was loaded up also.


Horiz Stab cracks/repairs: Don't do this...

If you find cracks on the horizontal web (ref SB 14-01-31) please do the repair recommended by Van's.
This aircraft is going to have to have a new horizonal stab made now because of the botched repair job.
The repair parts and install instructions (video) for this "Bracket mod" do not comply with Van's SB intent nor do they have any approval from Van's engineering. (it's also getting new vertical attach fitting).
It would have been much easier/cost effective to do the SB mod than it will be to build this guy a new stab.
I guess the guy who did this repair also preferred the looks of the all thread hex head fasteners more than AN hardware.


G3X/VPX trim - first flight eye opener

I had my RV-10's first flight yesterday, and thought I'd share something interesting that occurred, mostly as a discussion point: My trim did not work in flight.

System: G3X controlled AP, fronted by a VPX Pro, wiring setup as per them and Garmin.

I tested the system on the ground multiple times, and also had another person sanity check my results. This is my first "electric trim" aircraft, having flown a 182 for the past decade and having built an RV-8 with manual trim. A few days ago I realized I had an error: I had the up and down trim buttons on the control sticks reversed - the more forward button should be "down" trim, I had it as "up" trim.

Not a problem, the VPX has a control for both "normal" and "inverse". As well, the G3x configuration mode system also lets you change between a normal and reverse setting. Whew, I can just change this setting and I don't have to fix my wiring, great.

Swapping the VPX value, I checked the system again, and it functioned as expected.

First flight is here, and one of my sage pilot friends suggests I have a little nose-up trim for takeoff since I'm fairly forward CG on the flight, it'll help a bit with getting off the ground. Ok, on my checklist I go ahead and take his advice and do that - trim system move and responds as expected. Trim is now slightly nose up.

Takeoff, everything is great, but man that climb is a bit aggressive - need a lot of forward stick to overcome that trim. No problem, attempt to trim nose down - and nothing happens. Multiple attempts, no movement. I can see the g3x screen indicator for trim turn from white to blue every time I push the trim button, but it is most definitely not moving. This is becoming a problem, I'm pushing really hard to keep relatively level if not modest climb. Nothing is working though. Luckily I had a chase plane to help with traffic and tower while I debugging. Tried the copilot stick - same results. Went into the VPX screen on my MFD and attempted to the push trim up/down from there, same results. It was getting the signal, but not moving the servo. Meanwhile I'm pushing extremely hard with my left arm.  continue


10 Years Ago on This Day ...Vlad

Time flies memories fade. Having an extensive archive of digital images, detailed pilot logs and decades of daily planners I am giving it a try.

RV-8 and the Post Maintenance Flights ...ArlingtonRV

With the 2021 condition inspection completed all that remained was to perform a test flight to make sure that everything worked as advertised. Saturday 5/1/21 provided just enough decent weather to do that.

The weather on Sunday was better and I was ready to play. Carl took off about 20 minutes before me so I headed in the same direction. I caught up to him just north of Astoria and we flew home together. In the process, he managed to get some pretty good pictures of me.  -->video



Primer inside a fuel tank!?

A friend bought older RV6 partially built kit. He recently completed one fuel tank and went to start the other and noticed the parts were all primed except the skins. Of course he's wondering why the heck he didn't notice it before building the first tank. It looks like it is the Sherwin Williams wash primer. His question to me was "do you think the primer in the tank is a problem?" Gosh I really don't know I said. That's a good question for this forum.

He's ready to rip the first tank apart and re do it but would appreciate thoughts and input you may have. Thanks

Substituting rivets

Hypothetically, if someone were skinning a horizontal stabilizer, got the front spar riveted, then switched to riveting the ribs but forgot to switch to the shorter rivets called out on the plan...thereby installing 426-3-4 where the plans say 426-3-3.5 ... could such a person reasonably say that it's close enough, and honestly they look pretty good anyway, and it'd probably do more harm than good trying to drill out 30ish rivets. Hypothetically. Asking for a friend.

I did learn today that you can nicely buck a rivet that's too long to squeeze without clinching. So there's that.


Reusable AFP fuel filter and solvent ...Kahuna

Over the past 500 hours or so I have noticed a slow progressing need for the boost pump, culminating in fuel starvation and an uneventful landing on a recent cross country.

A check of the fuel line at the servo and boost pump on resulted in fuel shot across the ramp. Seemed fine. Test flight, and again fuel starvation.

A check of the fuel filter show nothing. Visually spotless. Until I tried to blow through it. Definite restriction. Cleaned filter with carb cleaner, and I could see a light yellow color in the solvent. Reassembled, and no restriction blowing through it. Problem solved. Flown another 10 hours until home with no need at all for the boost pump which is something I had not seen in years.

This is an AFP 40 micron filter. One of those 6ILA assemblies.

I checked the paperwork for cleaning instructions and "The filter element can be removed from the filter cap and cleaned in mineral spirits then blown dry with compressed air"

Hmm. "Can be"

Checked with a couple other high time experienced RV'ers, and they too had never run solvent through the filter.

With 2500 hours over 20 years on the filter, I have never done more than visual inspection, clean off any debris, and reinstalled. Never any solvent. I have no idea what had been building up in inside the element, but obviously something had. Also no indication in the docs about service life. Installed a new one.

1. Dont let a slow creeping issue go unresolved.
2. Clean the filter with solvent at annual.
3. After assembly, blow through the housing, it should blow quite freely.


Nerves Before a Flight ...many great replies

I love my RV, but before I make a big flight, I always feel a little but nervous. Tomorrow, I am supposed to fly from Borrego Springs to Reno, NV to spend the night. After the night there, I fly to Red Bluff, and then home. But, I find myself looking at this trip with some trepidation.

I'm nervous that maybe the weather won't be good enough, or I will not be able to get the airplane started when the engine is warm before I kill the battery, and I'll be stranded. I'm nervous about the aircraft getting its avionics stolen while it's sitting on the ramp overnight. Or maybe I'll get a flat tire.

What do y'all do to help calm your nerves before you fly?

My new puppy Loki ...ernestn

On April 13th I flew from CYPK near Vancouver to McKenzie in northern British Columbia to pick up our new 8 wk old pyrenees-husky puppy. I put the puppy in a crate wrapped in foam and blankets to deaden the noise. He slept most of the 3 hour flight and all went well. Below is a picture of Loki in the RV-6

Since the flight I have ordered a set of 4 Paws Aviation ear muffs and hopefully the puppy and I can fly some more. In the meantime in celebration I flew the flightpath shown in a flightaware image below. I planned the flight in foreflight and then transferred it to my Dynon Skyview and just flew the path. Worked out good.


Back in the Air ...Sam Buchanan post bird strike

Massaged the skin some more by applying pressure with hand and digits and got it to the point I'm ok with returning the RV-6 to service. If I decide to take the repair to 10/10ths the remaining ripples can be filled or a small flush patch installed then filled.

I'll may just apply a small duck decal over the wound....1st kill. <g>


Two Interesting Data Points on Leaning for DA

(Switzerland RV-6)
I regularly fly into "Europe's highest elevated airport" as they tout themselves, also know as LSZS Samedan. Fantastic scenery guaranteed
Imbedded in a valley, elevation is 5600ft, and access passes are around 9000ft. Flying LOP at my usual cruise of 12K, I usually enrich about 1" during the approach, for an eventual GA.
I then leave the mixture where it was after landing, and go enjoy a piece of the delicious local nut pie and a coffee
Before starting the engine, the mixture lever is moved another 1/2" towards rich. Run up satisfactory, take off is performed. The runway is some 1800m or 5900ft long, and gives plenty of time to find the best settings whilst rolling or initial flying.
Yes, knowing one's mount helps.

(Zimbabwe RV-7)
I have lived my entire life, and learned to fly, at 5000' msl with DA regularly above 7000'. I was taught to lean for takeoff from my first lesson, and we did it at run-up RPM. Later I was taught that for a performance critical takeoff a full power run-up, if possible, would yield a more accurate mixture setting but otherwise setting at normal run-up rpm, and erring on the rich side, was acceptable. This served me well for 3000' hours of bush flying, and I never clipped a tree or fried an engine that I know of.

On the certified fuel injected types (C-206, Cherokee 6, Baron) I think they all had altitude bands marked on the fuel flow guages and we would set the corresponding fuel flow on the takeoff roll. I thought I would work out something similar for my FI RV-7 but I find with mixture anything other than full rich CHT is on the high side, and performance is such that it just isn't necessary. The engine runs smooth as silk full rich so I'm doing full rich takeoffs at 5000' feet so far.


Fuel Tank Assembly

Q: (msstahl)
I'm starting work on the fuel tank assembly and the first steps are working with the Z brackets. The plans seem to be lagging the parts as all the holes are pre-punched/drilled which leads me to my question.

Is it necessary to bolt the z brackets to the spar, cleco the rear baffle to the Z brackets and attach the tank skin to check for alignment? With the accuracy of the pre-punched components this really doesn't seem necessary so I'm hoping others can validate my thoughts or provide the reason for the work.

I'm curious what others have done here before I start.

A: (PhatRV)
I created 4 templates that match the four corners of the wing tank skin and cleco the templates with the fuel-tank baffle to the spar flange. The template holes are matched drilled to the tank skin so the holes that line up with the skin and the baffles are all matched. This will keep the baffle in alignment as you drill the pass the baffle into the z-brackets.

But the pictures below should show how the templates are used.

Temp Control Baffle Mod...Michel Therrien 6A Update

I have to say a big THANK YOU to all who provided information. This really helped. I modified my baffle to integrate a bypass duct behind cylinder no 3. I also sealed all openings I could see. I flew today climbing at an aggressive angle and I was able to stay under 400F (!). Very happy with this now.


Rear Seat Throttle Parts

I have the deluxe DJM throttle quadrants from Flyboy Accessories. Both front and rear quadrants. Problem now is I'm trying to figure out how to install it into the fuselage as it's being built. I did not get the Van's rear seat throttle kit as I wanted the nicer DJM throttles. Looking at other builders logs, there's several parts I'm missing. The clevis and pins are easy. The pushrod and side plate are much harder to figure out. The drawing from Van's, DWG OP-2 is also easy to order. I'm really hoping to avoid ordering the whole rear seat throttle kit, just to toss half of it in the trash.

From what I can tell, I need to order the side plate, pushrod and drawing from Van's. I'm hoping someone is able to give me part numbers so I order the correct pieces. Please, if there's anything else I'm missing, or other suggestions let me know.


"Life Alert" while working in your hangar?

Wife & I got to talking, she worries about me working by myself, sometimes into the evenings, on my plane with no one else around at the airport. She feels that if I fell or had a serious mishap and could not get to my phone I could at least squeeze the bulb on a Life Alert type of emergency device to summon help.

I semi-agree, but pointed out that since she's also home alone a lot (I'm the usual airline pilot and can be gone for a couple weeks at a time overseas), she should wear one too, since we're entering the age range where our bodies start breaking down and I worry about her.

Has this occurred to anyone else, or is it just us? She'll come out to the hangar once in a while or stop by on the way to/from the sewing store, but she'd rather be home sewing her quilts. (if you want sticker shock, price a modern, professional level sewing machine, especially a long arm quilting machine.)


Sealant Mold Project


Landing Gear Puzzle - RV-8

RV-8 slow build. Lining up to drill the gear holes. I can't sweep the legs aft enough to make the leading edges inboard and outboard all line up on the same plane while being able to maintain proper edge distance on the outboard load plate and also at the limit of the aft bolt hitting the fairing z-channel even after relieving a fair amount of the corner.

My best compromise is to sweep aft best I can, ensuring the 3/16" edge distance is on the money laterally, and accept that the legs arent truly square across the entire leading edge.

Doing that, ensuring that the gear distance to tail is same both sides, and distance to a straightedge forward is same as well, I feel pretty confident the axles are going to be very close in position fore and aft.

The other reason I would like to sweep the legs more is for the slight toe-in condition that exists where the legs end up. See in the pics I clamped straight edges to the foot of the leg to measure the toein. A foot aft of the axle the straightedge shows about 5/8" wider a foot behind the axle than at the axle (the two legs are toed-in 2.5-3 degrees). Not sure which is more or less because I don't have the true centerline to measure to up there. I presume I can fix this with shims. I think it will change a bit once the bolts are in and down too.

Am I making the right compromise or am I missing something in my setup?

Lost right brake

We lost our right brake while turning on to the runway for takeoff. Spun around a couple of times and got it stopped. Saw fluid leaking out of failed brake. After the 1/2 mile walk/pull back to the apron we pulled the fairing and saw the puck fully extended. Got a ride back to home base from a friend and packed the car to fix the problem. Pads were extremely thin and I believe that coupled with the original brake rotors allowed the puck to extend past the seal.

Thinking we need to replace out brake rotors as well and am looking for suggestions of Rapco vs Cleveland. Price for the Cleveland is X2.

Thoughts ?

One quirky cylinder

I trying to get some dual instrument time in that I need before I can write my instrument rating written test next week. My engine is having other ideas, had to scrub several flights over the last 2 weeks because my engine is just not right.

Some baseline information, I have a IO-320 built to zero time with 2 Bendix mags, Precision Airmotive Silverhawk EX fuel injection. I have 178 hours on this setup. Last year I had a fuel starvation event on takeoff that resulted in replacing the bearing kit on the FI servo. The mixture wasn't setup correctly after that reinstallation (way too rich) and I had a couple of engine quits on rollout before that was fixed. Recently I noted a 400 rpm mag drop on the right magneto on runup and also had the timing on the left mag fixed (from 27 degrees to 25). Everything ran well after that, but I didn't get much time in. I changed the oil and filter a week ago.

Now my current issue. Last week I was taxiing for departure and found my engine was running roughly, almost like it was running on 3-1/2 cylinders. #1 CHT was higher than the others and #1 EGT was more than 100 degrees colder. Cancelled that flight and did some inspection. Injector and fuel line from the flow divider were clear. Spark plug (R mag) tested good (L had been checked 2 weeks earlier). My mechanic/engine builder pulled the R mag and replaced a weak coil, it tested good as new. Reinstalled the mag and did a couple of good runups. Mag drop was still a little high, right around 200, but much better and the engine seemed to run fine.

Today I went to try a test flight and after a fairly long ground run (with mixture leaned for ground running) I entered the runway and immediately did a 180 to come back off. Engine was stumbling badly. Did another runup and my right mag drop was pushing 260 with the last 60-80 coming with a lot of roughness. No real roughness on the left mag, 120 drop or so. #1 cylinder temps were 40F higher CHT (350) than the others and 100+F lower EGT (1000). Other cylinders were all similar temperatures. The roughness was getting worse, but was not constant - maybe 1/2 the time on a 30 second cycle or so. Taxied back to my hangar and shut down. My mechanic had me do a per cylinder fuel flow check. With a 2 second boost pump burst, front cylinders delivered less than the back ones, not by a lot, maybe 90%. #1 was the lowest flow but only by a slight amount.

In what may be nothing but coincidence, I had radio TX issues today too. RX was good but tower was having difficulty hearing me, saying there was a lot static. One radio was worse than the other and I'd never had this issue before. Maybe this is a hidden clue, maybe it's nothing.

Next troubleshooting session is tomorrow morning where we are going to check the flow divider, particularly at the #1 port and test the ignition harness. The thinking is that there is either something inhibiting fuel flow intermittently or the ignition wire from the right mag is faulty.

Anybody have any ideas what else might be causing these issues? My mechanic doesn't think that it should be a sticky valve, the engine isn't all that old (2-1/2 years) and has been well maintained. I just want to trust it again.

Alum. Canopy Fairing Update ...mburch

I searched high and low for something with the right combination of stiffness and flexibility that I could use to mark a smooth curve to trim the top of the windscreen base fairing. I happened to stumble on the notion of using a piece of exterior door weatherstrip and it worked perfectly. The kind that's made to fit into a kerf slot in a door jamb has a hard rubber edge that makes it easy to mark your trim line, after you establish the shape by taping it down at a few key locations:  -->


Bird Strike Club: New Member ...Sam Buchanan (after 30 years)

After coexisting uneventfully with our feathered aviators for thirty years my luck ran out today. If this can't be pulled out enough for "body repair" this will be a long, involved repair. No telling how long it would take to get an RV-6 leading edge skin from Vans these days.....

Very grateful it wasn't a canopy or tail strike.


Reinforcing Canopy Crack

Despite using Sikaflex, my RV7A slider canopy developed a crack after sitting out on the tarmac for a cold night this fall.

I stop drilled, which has stopped the hole growing. Then I repaired with Weldon #3 in the crack as other builders have reported on this forum. The repair held for about a month. I repeated with the same results.

Any suggestions how to reinforce such a repair?

I'm pondering bonding a thin half-inch-wide strip of something transparent and moderately flexible to the underside of the crack, but am unsure what materials to use.

Or maybe it just needs multiple applications of Weldon or some prep of the top surface of the crack?

Trim and Throttle Placement Experiments ...David Paule -3B


Panel Update...Pilotjohns 9A

Panel is nearly done with the wiring. Many things I have learnt from all of this.

AP wiring: I had the AP power controlled by a switch and fused instead of a circuit breaker. The G3x manual shows the 507 controller and servos all being powered from the same fuse. I originally had the 507 and servos on a switch, but I have changed that to just the servos on a switch. That way, if I kill the servo power, the 507 stays powered and should give be pretty purple boxes as guidance; there seems to be no reason to kill power to the 507 in an emergency as long as the servos are powered off. The AP switch is wired so that the green portion is illuminated when AP is powered, and the red portion is illuminated when there is no power to the AP servos

Bus bars: i made the circuit breaker's bus bars out of copper sheet. I wish I would have spaced the circuit breakers out more; it would have been easier to get the screws in. Also, the CB screws are flat heads, these should be changed to round head Allen or Philips style; it is hard to start the screws using a flat bladed screw driver. I found labeling the back of the CBs really helpful.

The bus bars have clear shrink tubing over the areas between contacts to minimize potential for shorts. This is all protected with an 35A ANL fuse forward of the firewall.

There is no longer a AP disconnect switch on the panel. I dont see a need to disconnect the autopilot unless my hand is on the stick, so only the stick has a disconnect (along with the "AP" button on the 507). The trim CB was moved in front of the pilot and position to be operated with the right hand. If I have a runaway trim, one hand is going to be fighting the stick, so I want to other to be able to pull the trim CB.

The defrost fans did not need both a switch and a CB, but I had extra CB holes and my fuses were all assigned. so room for growth.

I was hemming and hawing about the defrost fans. I was thinking of putting the antennas on the glare shield in recessed mounts. I gave up on that so the fans are staying on the glare shield. The antennas will go under the cowl.

I painted the panel with the Sherman Williams Jet Flex that I used on the interior of the fuse. This paint is really good; flows out easily, is durable, and just works.

The taxi lights and landing lights are on the same switch. I wanted a off-taxi on-landing light on switch, but the world wide shortage has me with a taxi on-off-landing light on. I will switch this out once the preferred switch becomes available.

The radio stack is not quite centered, I moved the left screen, the rack and the right screen as far over to the left as I could go. I was hoping the left screen was centered in front of pilot, but didn't quite get there with the G5's position.

Lastly, all power terminals screws have lock washers. (yes I changed my mind)

Move to the Hangar ...Iluke

Saturday was a really big day for our RV-7 project- The move from home to the hangar after 9 years under construction.  It all went smoothly and we hope to be flying soon


No Mo Funk ...salty

We finally broke out of the funk and had a good morning of driving rivets. Riveted for over an hour and only had to drill one out - and no scratching!

The weather stripping suggestion is one I hadn't seen before and it worked really well. Also used duct tape instead of painters tape and that worked better as well.

Thanks to all for letting me vent and providing helpful hints.


G5 Optimal Location ...MacCool

For me, G5 is only a backup...I mainly use the PFD and MMD for flight/navigation, but mounting that small display close to my center of view works great, as would be optimal with any HSI/artificial horizon.

The one thing I've found mildly irritating about the G5 is that it's not flush-mounted...it sticks out from the panel. A curious mounting decision on the part of Garmin, IMHO.

Anyway, they do make a mount that lets you mount the G5 flush with the panel. I haven't installed it yet, but it is on my rather long list of things to do.


Remove/Install Propellor Lug

I had occasion to remove one of the propellor lugs so I could drill & tap a hole in the case for the electronic ignition.

Since a picture is worth 1000 words, here are three -- first one shows the removal stackup, the nekkid hole, and the last is the installation stackup.

Cheaper than buying the actual lycoming tool, which I believe is made of an alloy of unobtainium with a .002" coating of unaffordium.



Plastidip ...Cammie Patch

I primed then put about 5-6 coats of Plastidip on the forks of this aircraft, then used normal paint on the other -12. The plastidip has held up great over hundreds of hours. There are enough color choices to get a good match, and I can peel off and reapply when needed.


Rubber Bottoms ...DanH

Mold in place then cut away the glass underneath, bond into place. The edges are tight to the tire sidewall.

I operate these with 3/4" ground clearance, everywhere. In rough places I'm more concerned with tire's rolling diameter than the wheelpants.

...Here I am, a white male, age thirty-eight, height 5 feet 11 inches, weight 165 pounds, salary $17,000 per annum, resident of a Texas suburb, with black spot on my roses, state of mind unsettled, about to be shot off to the Moon. Yes, to the Moon.

At the moment, the most important control is over on Neil's side, just outboard of his left knee. It is the abort handle, and now it has power to it, so if Neil rotates it 30 counterclockwise, three solid rockets above us will fire and yank the CM free of the service module and everything below it. It is only to be used in extremes. A large bulky pocket has been added to Neil's left suit leg, and it looks as though if he moves his leg slightly, it's going to snag on the abort handle. I quickly point this out to Neil, and he grabs the pocket and pulls it as far over to the inside of his thigh as he can, but it still doesn't look secure to either one of us. Jesus, I can see the headlines now: "MOONSHOT FALLS INTO OCEAN." Mistake by crew, program officials intimate. Last transmission from Armstrong prior to leaving the pad reportedly was 'Oops.'"

RV-8 and the 2021 Condition Inspection ...Steve Rush

2021 marks the 20th anniversary of the completion of the RV-8 that I recently (Dec 2017) bought. In 20 years it has accumulated 2,172 hours of, mostly, issue free service. I just finished up the 20th, well 21st if you count the pre-certification one, condition inspection.

This year's inspection went reasonably well, but I was introduced to a couple of issues I hadn't experienced before. The full story is linked below. I primarily wrote this up for myself to provide more details of I what I did in the future, since the remembery isn't what it used to be. A checklist and log book entry don't necessarily capture everything.

Since it already exits, I figured I would share it with the group in case it could be of any use to anyone. If nothing else, it is guaranteed to sure your insomnia.


Trailing edge of wing scraping top of flap

Not sure the best way to fix this on our RV-10. We've noticed we have some scraping on the left flap where it slides under the trailing edge of the wing. I uploaded two images: one where I marked all the places it is scraping with blue tape and another of a closeup of one of the worst spots. It doesn't look like it's the shop head side of the rivet that is doing the scraping since the scraped areas are pretty wide.

I contacted Vans for advice and this is what they suggested:

"I think if you smooth off the lower surface of the trailing edge of the skin at an oblique angle with a light file and then sand it smooth this may help, along with smoothing the light gouges in the flap. This collision is not that severe so small modifications might help here.

Depending on when you plan to paint the aircraft, it may be wise to fly it for a while and allow the areas to "match" each other before painting. This way you will probably reduce the damage to the paintwork.

Radical remedies like using a small hammer to tap the flaps at the collision points and removing rivets along the top skins and then re riveting may be too impactful initially but may be an option if the first ideas don't help."

I did sand away the underside of that overlapping edge at an angle and sanded out the scrapes on the flap but I'm concerned that even if this fixes it it will scrape after painting since the paint will build up the surface of the flap enough so that it may touch again. We did buy some of the Paint Protection Film to put on the underside of trailing edge but that will also make the fit tighter. We will probably take it to get painted in January

Anyone else have this issue?

Tailwheel arm play - normal?

Hello all, I've noticed that my tailwheel arm has some play as seen in the video link below. No issues with controlling the plane but I am wondering if this is normal or not? If not, it looks like the only fix is to put another large washer between the nut and the other washer?


RV 8 Landing gear NUTS!

Q: During inspection of my RV 8 landing gear I noticed one of the outer brackets was bent. I grounded the plane and ordered both the outer and inner brackets. The inner bracket was a challenge but the outer bracket is proving to be impossible. After a lot of headache and some verbal language I would never use around women or children I was successful in getting the bracket off. I got the new bracket in place and got both bolts through. Here is the issue... I was finally able to get the nut finger tight on the on the forward bolt. However, after 6 hours, bruised left forearm, bruised ribs from leaning over the side of the cockpit I finally gave up trying to get the back nut on.

I tried just using my hand and holding the nut with two fingers, I tried using painter's tape on the nut so I could put it in a socket and have it stay there while I tried to start it. I tried praying, pleading and offering my soul as sacrifice with no luck.

Looking for any advice from anyone who has changed these brackets after the build with wires, brake lines and fuel lines in the way. Frustrated...

A: There are two AN3 bolts that may interfere with the nuts. They are shown in the cropped picture below. You have to loosen the AN3 nut so the bolt will retract to allow you the clearance to insert the nut from inside the gear tower. At least I think this is the problems from your description.

I also find it helpful to use Gorilla tape to secure the box wrench to the bolt head underneath the gear towers as I torque the nuts inside the tower. The tape will hold the box end to the nut to prevent the wrench from falling out. The long arm of the wrench will wedge against the landing gear structure to keep it from moving as torque is applied. I am not looking forward to retorque the nuts when I get my airplane flying. I also hope you are replacing the stock nut with the upgraded NAS nut as described somewhere in the RV8 forum

P.S. I find the open thread length of the original AN3 bolts is a bit long the long side which interferes with the access to the landing gear tower nut. I replaced one AN3 bolt with a slightly shorter one, still keeping 1 thread showing, to prevent the access problems you are experiencing


CQ1 Headset now available with LEMO style plug

The CQ1 is now available with a 6 pin LEMO style airframe cable.
It is still the same great passive headset that does not utilize or need ship power and still weighs only 3.7oz in total. You won't currently find this option with the competition.


Fusebox Porn ...Nihon_Ni

I used the same type of connector as Jim. I put it in the forward baggage area of my RV-8, and used an AWG 10 wire to supply power to the Main Bus via a 30A fuse. You can see it on the left side of this picture, connected to my ground power unit, and the thick red wire running to the fuse block. I'm essentially running power backward through that slot in the fuse block in order to power everything else on the ground.

It's been useful in the building process to check each component as I install them. Although I always check continuity with an ohmmeter, I did find an issue when I wired my map lights in series but they wouldn't illuminate under power event though there was continuity.

I plan to use the ground power for panel updates once the plane is flying. I'll have a separate connector to charge my EarthX battery.

1-Piece Alum Fairing for Top of Rollbar ...mburch -7

I turned a six-foot sheet of 0.040" into a single-piece fairing for the top of the rollbar. I got as far as getting it fitted and the aft edge trimmed to final size, before I ran out of weekend. I'm pretty happy with the fit so far - I was able to get a fairly consistent gap all the way around. Next step will be to trim the remaining edges of all this aluminum.  -->many pics


Bench Wiring Progress ...Philip

Whew. Got all the wire laid in as of today (with the exception of two small parts, for which I'll get materials in tomorrow). Which meant it was time to start dong some cable lacing. Not quite sure how much of this I'll do on the bench vs. in the plane, but this particular branch will be in the gear tower, so it's pretty much now or never.

It sure is satisfying starting to turn those piles of wire into nice bundles.


Just got my first RV Grin, thanks to RV8iator ...VANDawg

I contacted him through this site and asked if I could bring my wife and look at the plane, since I was planting the seed that WE needed a plane to buzz around the South East visiting our kids. One of my twin sons, my bride, and I show up at the hangar and get the full tour of a beautiful RV-8, and then get offered a ride. Not being one to turn down a ride, we coaxed the bride into taking the first trip. Ajax and a wire brush could not have wiped the smile off her face. Let's just say that the ride home was filled with her gushing about how much she loved it, and that it was so much nicer than the C172 that my son uses when he teaches at the flight school in Jax. I agreed, but also reminded her that she was riding along with a pilot that made it look easy
Jerry was fantastic, and both he and his hangar mate George were nothing but encouraging about our quest for our own plane. All I can say is, thank you gentlemen. I hope to join the rest of you as an RV owner in the near future.


Fuel tanks venting through caps

I know the fuel tank vent line design in the -4 makes it exceedingly difficult for any fuel to exit through the vent. What I'm seeing is my tanks are venting fuel through the center of my caps after a fill up. I have the old black o-ring caps, for reference.

Is this a common problem? Should I look at rebuilding my caps or is this something I'll just have to live with due to the vent line design?
