Tributes to Mr. Tom Irlbeck
like to add my comments to the passing of Tom

25 years. I gave him his BFRs for the last 10 years
or so. A great friend and a great aviator. Here my
thoughts on our

weekend! I sent his name in to Van's as the person
who referred me so he could get as he called it,
My favorite Tom story was from a breakfast trip the
Twin Cities group took up to Superior, WI for
breakfast. One of us would give a position report
over a little town on the way up, and no matter what
the town, with perfect timing, Tom would chime in
with, "I used to know a girl in that town". We'd all
laugh, and just knew, Tom was always a true Naval
He was the best, and we will all miss him.
Tom was a huge part of our EAA66 at page in ft Myers
He was more than a mentor.

always available and made time for who needed his
advice. The young eagles he flew always had that RV

(Thursday) 7pm Founder's Wing at EAA Aviation Museum
milestone today. I finished installing wings,
plumbing, wiring and checked all of my aileron up
and down movements. The stick movement seemed a
little heavy left and right but ok forward and aft.
I probably wouldn’t have ever second guessed the
heaviness had there not been another RV4 in the
hanger next to me. It’s movements were effortless,
but I did have the servos connected from an auto
pilot installed. I thought maybe this added the
extra drag in the controls. Not satisfied I
disconnected the aileron servo and still had the
heavy stick both left and right. I start with left
and right aileron bushings/washers, any possible
rubbing of close parts. Moved on to the aileron push
rods checking all rod end bearings and washers. Next
the bell crank and then the large push rod tubes all
moving freely I install them back and still heavy
left /right movement on stick. I examine the stick
control for binding or interference, and then
finally removed the heim bearings for inspection.
I’m down 2 days so far, but finally found the
culprit. The rear heim bearing has been damaged
ever so slightly. The small crease on the brass
has also creased the interior of the housing race
causing the bearing to bind. I just wished I’d
started looking from that point first. Lesson

Too much slack in tailwheel chains? ...sorta a primer war
There's another post about using or not using
flaps in cross wind landings. Let me throw a new
wrinkle in this discussion. I "think" I've got too
much slack in my tailwheel chains, making it take
longer when I hit the rudder pedals for the rudder/tailwheel
to react in strong crosswinds. What say the rest of
you guys? Do you have your chains really tight, ie,
no slack? Slightly loose? Or really loose?

Interesting day today, lots of smoke in the cockpit! ...Walt
So while doing a small panel upgrade for a
customer I had a bit a meltdown on his aircraft. The
panel mounted Lightspeed CB, with open and bare
terminals was connected directly to the battery, and
was located right under the xpdr rack I was
replacing (within about 1/8"). Well as soon as the
rack came loose it came into contact the uninsulated
terminals. (of course I was unaware at the time that
this situation existed with a hot bus right below
I can tell you this, there was a ton of smoke
accompanied by some small flames as the wiring began
to burn, disintigrate and melt. All the switches and
master were off so there was no killing this thing
and it just continued to burn until the wiring
finally burnt thru. I was scrambling to get the cowl
off so I could disconnect the battery, but by the
time I got if off the wires has already burnt thru
and opened up.
So whats the moral to this story, do not run 'HOT'
unprotected (no fuse, CB, contactor controlled)
wires into the cockpit. This situation could have
easily presented itself from any number of causes
(loose hardware, wires, breaker, switches getting
loose etc.) If this would have happened in flight
there was no way to kill power to the burning wires,
and trust me with a closed canopy you would be in
serious trouble fast. I was really pretty amazed at
how much smoke there was, in the air this likely
would have ended badly.
For your Hot battery busses (this includes battery
charger pig tails) there should ALWAYS be a fuse (or
some type of circuit protection) located at the
battery to prevent this kind of thing from

sharp. We may cut this area out and reglass with a

will do. The only drawback is that since it is
inside, if you have any leaks in the forward edge of

have to make up some sort of temporary overnight

further but my plan is to use some white electric

RV-8 O-360 Temps and Fuel Flow issues
Just wanted to push out to all of you to see what
you guys think about some of the engine issues I
have. O-360, fixed pitch, dual P-Mags, Dynon D10
EMS. CYL #3 runs VERY hot even on cold days, even in
cruise with CYL 2, 4 not too far behind. CYL 1 runs
much cooler than the others. You can see some temps
I see on climb and cruise taken on a winter day at
altitude. Anything slower than a 100 KT climb will
have my #3 CHT shoot to above 430 rapidly.
Also on climb out and WOT I will see my fuel
pressure typically drop quickly from a nominal 3-4
PSI to .5 and 0 PSI which sets off the alarm. I've
noticed this is often accompanied by an increase in
fuel flow. Turning on the electric pump will push
these up to 4. Securing the electric pump, the PSI
will gradually decrease again to .5-0. Once
throttling back to cruise settings the fuel pressure
will climb back to nominal.
I am wondering if any of you have any ideas on the
fuel flow and the over heating. What's a good way to
check the baffles? Are there any good plenums out
there for my configuration that has shown good
success in cooling so I can do away with worrying
about baffles? Searching through the threads it
seems adding a washer helps with cooling but I'm not
quite sure where that washer is being added....any
photos to show this?
Otherwise the motor runs nicely and no noticeable
performance issues associated with the drop in fuel
Any input is greatly appreciated!

Here is one way, but the baffle would have to be
removed for this. It provides air to an additional

head polished at the same time. Why have the fins
and allow them to be blocked off? This provides a .2
X 2" slot for air flow, at 5-15 in-h2o pressure that
is a lot of air directly applied to cooling.

Tuft Testing RV-8 Sub-Cowl ...JP White video
My partner and I felt we were
overcooling our O-360 XP so he designed and built a
sub-cowl to reduce the exit opening and reduce
cooling drag. We expect the reduction in exit
opening will increase the CHT and oil temp. Testing
has been limited due to weather and schedule but we
have noticed a very modest increase in CHT and oil
temp. I tufted the belly around the exit and
recorded the flight to get an idea of how the
sub-cowl disturbed the airflow. The test was at
3000' and 160 - 170 mph. A link to a short video is
attached. RV-8 with custom plenum and Sam
James Cowl. Carbureted 360XP with Mags. FP Cato 3
"The ramp surface of your sub cowl is separated
because the angle is too steep, so there is too much
adverse pressure gradient.
I trust that the leading edge of your sub cowl
blends smoothly into the round lip at the front of
the stock cooling channel? If not, then the flow is
separating off of a sharp corner. If yes, then it is
an adverse gradient problem as stated above.
This is just one of the reasons why it is far better
to throttle the exit by making the actual cowl fair
into to a smaller opening rather than add a bulge to
the belly. The other reason of course is that the
frontal area is reduced at the same time."

Snowbird Classic IAC contest PIREP
The 2018 contest season has gotten
off to a good start!
We started off in March with a successful judge's
school. I got recurrent and now it was time to start
judging. I was hoping to start by judging either
Primary or Intermediate. The problem was Primary was
combined with Sportsman for this contest as it often
is. So I wasn't permitted or able to judge the
category since I am a Sportsman competitor. The
Intermediate category was being flown just prior to
my category so I wasn't able to judge it. So for my
first judging experience as a qualified Regional
Judge I got to judge the Advanced category! I was
bit apprehensive about this since the competitors at
this level are very serious and I didn't want to
screw it up for anyone. Plus, the maneuvers happen
very very fast, making it easy to miss important
elements. You know what... the training worked! I
was able to successfully judge in a fair objective
manner consistent with the more experienced judges.
I was as pleased with this as I was with my flying.

14A flying feedback after 237 hours ...bmarvel
I rarely post but thought some of you in the early
RV-14 flying stages or nearing completion may be
interested in some real-world feedback. I first flew
our -14A on September 8, 2016 and now have 237 hours
on it. Prior to that I put our RV-8A through some
1700 hours so I know the pros and cons of each. Our
-14A was a standard full build kit (SN 140134) with
an IO-390 from Van's and the recommended Hartzell CS
prop. It is IFR with two Skyview displays, GTN-650
navigator and a back up Grand Rapids Mini-B EFIS. It
has an impulse coupled mag on one side and P-Mag on
the other. I followed the plans closely and only
made minor modifications to them.
In no particular order, here are some thoughts,
characteristics, performance data and features that
may be of interest to you:
1. Both the wife and I find the -14 to be more
difficult to get into and out of compared to the -8.
One hand on the side rail and the other in the
center of the cross bar behind the seats is required
to support your body weight, especially getting out.
It takes some stretching to do. Don’t let pax grab
the instrument panel or canopy, as they are inclined
to do. Holding onto the roll bar while facing
inboard and standing on the seat, then turning
forward while crouched down like a baseball catcher
leaning against the seat back is a technique that
works. You may end up developing your own method
that differs but that’s what I do.

Friday April 6, 2018 from 1300 to 1500 at the
Georgetown, Texas airport.
We are hopeful the weather will hold up and that we
can accomplish all that we can on such short notice.
We will plan on starting the posting of the colors
at 13:45 followed by an eulogy and stories about
Falcon. We will perform a missing man in his honor.
Any one that has served or flown with him don't
forget to bring your nickel. Please think of a short
story or quote you would like to share with those in
attendance. Remember that this is as much for his
family as it is for him. I believe it is important
for his grandkids to get to hear these stories they
otherwise would not hear. Please think of a brief
story if you want to share one. Try to keep them PG
as most of us coming from fighter squadrons tend to
have some flowery language at times, along with some
of our sayings. That said Falcon loved the
camaraderie and shenanigans as much as he loved
formation flying. He would want it that way.
Please let me know if you need anything further. I
hope to see you at the "Falcon Gathering".
Please forward this to anyone you may know that
would like to know about this gathering as I am sure
I have missed someone, unintentionally.

RV-8 Heat Diverter- Solution to a Nonexistent Problem?...goatflieg
When I installed Van's cabin heat selector box on
my RV-8 firewall I saw two potential problems. The
first was routing the push-pull cable; with ground
adjustable rudder pedals set full-forward I saw the
potential for getting the top of a pedal caught
behind the cable during brake actuation with rudder
deflection; definitely NOT a good scenario. I
decided to modify the flapper lever and route the
cable directly from the left gear tower to the
lever. This would reverse the operation to
push-to-open/pull-to-close, but that's no big deal
to me. The other issue was that it looked like the
hot air would be blowing directly into the left
corner in front of the gear tower; less than ideal,
with wiring, cables, fuel pump, fuel lines and brake
lines there. I thought a heat diverter would help
reduce those issues and redirect the hot air
straight aft. So I made this up out of scrap
aluminum. It was eyeball-engineered and took some
fiddling, but I believe it will help. Having to
route the cable through the diverter was a pain, but
it works without any interference. Just wondering if
any other RV-8 builders had similar thoughts. Did I
solve a nonexistent problem?

Taking advantage of a TDY ...majuro15
I’ve been TDY (temporary duty) at Sheppard AFB, located in lovely
Wichita Falls, Texas, for about two months. While this place chalks
up to the armpit of the Midwest, I was determined to get out and
enjoy myself during the three months that I’m here. Luckily, another
class mate, Justin, in my Aircraft Maintenance Officer training is a
private pilot and we quickly found a few great places to airport bum

John Hooker, located at Wichita Valley Airport (F14), built a very
nice RV-10 several years ago and was happy to show me around and
give me some tips. Ironically, a unique feature spurred my memory
and after digging through Oshkosh photos from four years ago, I
realized I had seen his airplane in person. When we couldn’t find
any good reason not to fly, he offered to take me for a quick hop
along the Red River and gave me plenty of stick time. I’ve been

Stu McCurdy: Rest in Peace
It is with heavy hearts that Falcon Flight

his home in Round Rock TX, surrounded by his entire
It's no exaggeration to say that formation flying
in the GA world, especially the EAB side, would not
be the thriving, tight-knit, community that it is
today without the efforts put forth by Falcon. His
creation of FFI back in the late 90's set the gold
standard to which we are all held. It allows dozens
of flight teams, consisting of hundreds of pilots,
to fly together in safety and grace. It seamlessly
brought together pilots from all over the country to
set world records, whether over EAA AirVenture, NFL
games or the occasional NASCAR race.
An informal “open hangar” gathering is planned
for Friday 4/6/18 from 13:00 to 15:00 at Stu's home
base of KGTU. Feel free to drop by and pay respects,
if so inclined.
Falcon *will* be missed, but his legacy continues
each time we “strap on” our aircraft.

The Harding Icefield is an expansive icefield

Fishing Guide RV Offer (NE. OK) ...friend of mine Clayton (RV-8)
Adam Mason is a friend of mine here in North East
Oklahoma. He was born and raised in Adair and has
been fishing Hudson Lake since he was a kid. He has
started up a fishing guide service, and I was hoping
to get the word out to the RV community since this
would be a great use of an RV. Adam is a Veteran,
having served in the Army between 2004 and 2012 -
with a tour in Iraq (2006/2007) as a .50 Cal.
Infantry Gunner. Not exactly sure what he was up to,
but I'm damn glad he was doing it.
Here is what Melissa and I would like to do to help
out. We would like to offer accommodations for two
different 2 person parties who wish to book fishing
trips with Adam. They can come into our grass strip
(OK18) on the lake the night before and either stay
in the one bedroom apartment we have at the hangar,
or if they prefer, they are welcome to pitch a tent
and camp. OK18 is a private strip with a "Land at
your own Risk" policy, but if they have some time
operating off of turf, coming in and out of OK18
should be no problem.
Pics and Contact Info
I would encourage interested parties to first
contact Adam about time and schedule. I know he has
been having some great results on Crappie and that
the Sand bass are really turning it on right now.
Melissa and I spent all day Saturday putting them in
the boat. Early in the season the Spoonbills are
really stacking up and the Catfish will be biting
here soon. Adam offers a full services guided trip,
all equipment, bait, lures, boat, and fish cleaned
for you to take back home. The fishermen/women will
be responsible for the appropriate fishing license
and their meals. His 1/2 day trips are $300 for
either 1 or 2 guests in the boat. I can guarantee
you that anyone who goes with him will have a good
time and Adam will do all he can to put fish in the
boat (remember - he can operate a .50 caliber rapid
Once the party has booked with Adam, I will be happy
to brief them on OK18, alternates, fuel,
transportation, and how to handle meals.

I went to the hangar yesterday to take the RV-6A
out after a cold winter's rest. After an extensive
preflight, I pulled it out of the hangar and climbed
in and started it up. As I was getting everything
set up and slowly continuing through the checklist,
I glanced up and notice a small crack in the
windshield that I hadn't noticed before. I almost
had a breakdown right then and there. The crack is
about two (2) inches and it runs from the top
left-center down and it is not noticeable while
seated unless you intentionally search for it.

25 years of bits and pieces ...Tom Martin
Although I would not call myself a hoarder when
it comes to little bits of aluminum I am definitely
In 1993, when I started, you kept all the scraps. If
you wanted to build something extra, or had a
repair, little pieces came in handy. When building
if you were going to modify a part you needed little
pieces. The really expensive piece of small aluminum
is the one you do not have! I kept everything,
different sizes, different thicknesses etc.
As kits have evolved there is less and less need for
extra metal. The kits are pretty complete and there
are not as many modifications to make. The baffle
kit alone has saved hours and hours of work
scrounging for just that right bit of metal.
After completing the RV14 I noticed that I did not
go to the scrap yard (under my bench) at all. It was
time to clean house.
It took a couple of hours to sort through 5 boxes
of odds and ends. I narrowed it down to two boxes of
high end scraps!
The rest went to the scrap metal yard

I don't have dimensions handy but this pic gives
you a general sense of the canopy frame "overlap" on
the panel. When closed, the bottom of the frame just
covers the 8/32 pan head screws around the top
perimeter of the panel....the dimension widens from
the top to the sides (guessing 3/4 inch at the top
to 1 1/2 inches at the sides.
For reference, the two screens are 10.4 inch HXrs
and the radio is a GTN650. Note that the panel
itself is a single piece of 1/8 inch thick aluminum
rather than the standard 3-section panel from Vans.

From Sonex to RV-8
Years ago when I first decided building an airplane
was something I wanted to do, I was quickly drawn to
the RV-8. As I started researching what it would
take to build one, I started realizing that cost to
build and the complexity was probably more than I
could chew. I found myself migrating over to the
Sonex, and after a Sonex builder took me for a quick
hop around the patch, I was sold. It had great
performance for the price and I was able to see past
the somewhat odd look and overall lack of fit and
Fast forward a few years and I am part way through a
Sonex tail kit but have started to have a lot of
apprehension about finishing. This is mostly due to
my lack (and others in the Sonex community) of
confidence in the AeroVee VW conversion. With the
Sonex B models, the factory will now support several
other more proven engine installations (Rotax, UL
power, etc.) but that takes an airplane I was
looking to spend 30-35k to get airborne to more like
50-60k. While I still feel the Sonex is a great
little airframe, I can't see paying that kind of
price for it.
So, I've come full circle back to the RV-8, which
has always been the plane I wanted to build in the
first place. I am going to order a set of preview
plans and the practice projects and figure out what
extra tools I'll need now that I can't just pull a
bunch of pop rivets. Any other building
advice/suggestions for a soon to be former Sonex
builder would be appreciated.
Looking forward to the journey!

After spending two hours last night trying to get
this assembly into place, I thought I'd better get

having much of an issue with it. Trying to figure
out what I'm doing wrong. F-01479 goes between the
F-01478 (skin) and the F-01411 bulkhead. I'm not
having much trouble there, it's getting the skin to
fit aft of this point. By the way, the plans are

I put three access panels in the front skin of my
9 tip up. It’s time consuming to do it. I asked a
friend that put them in his 7 if he would do it
again and he said yes. So I went for it. They made
it very easy for riveting the skin. I’m assuming you
have not installed the skin. Important. When laying
out the holes, the two that are on the sides run
parallel to the longeron. They are trapezoids not
Layout the locations on the skin and carefully
cut them out, file and clean the edges. Layout and
drill #40 holes around the perimeter using proper
edge distance. I used a rivet fan to space the
holes. Cleco on the skin to the airframe to fit the
backer plate. Rough cut the plate oversize as it
will change as it curves. Match drill the backer
plate and cleco all around. Trace with a sharpie
around the hole onto the backer plate. Remove the
backer plate and create an outside line 5/8” from
traced line, then do the same 5/8” inside the traced
line. Cut both inside and outside line, clean and
polish edges. You now have your backer plate.
Next make the cover plates. These must be made
with the skin cleco’d to the fuse. Rough cut larger
than needed. Match drill and cleco. You will need a
helper to climb in and push the plate to conform
while you match drill. Trace and cut 1/8” outside
the line. The plate now needs to be finely tuned to
fit the hole. Cut and file to fit. Cleco on the
backer plate for support while fitting. When your
happy with the fit, if not make another one, layout
#40 holes, match drill cover plate into backer
The rest is straight forward. Dimples for rivets and
#6 screws in cover plate. Install nut plates in
backer plate. Last is to rivet the backer plate if
your satisfied with the fit and finish. Otherwise do
it all again. It’s only a small amount of 032 sheet

My Vans RV Conundrum ...new guy Dave chimes in
I have been thinking seriously about trading my
Mooney for a Vans RV-9/A. It better fits my mission
which is mostly me flying around by myself in good
weather with no particular place I need to go. I
think it would save me a bit of money in fuel burn,
replacement parts and upgrades and it would be newer
with not so much history, mechanics, repairs,
annuals and the like on it.
My ideal Vans would be the 9/A with an IO-320, CS
prop and either a tip up, or slider, I haven't
decided. It would also have to have a nice, standard
layout panel with at least two axis auto pilot, dual
coms, WAAS GPS, engine monitoring and a good audio
panel. ADS-B in and out and a 406 ELT would be great
too. Unfortunately there are four serious things
preventing me from pursuing this plan. In order of
What do you guys think?
Safety. I like the 9 because it has the lowest
stall speed and that means the slowest touch
down in an off field landing scenario, but it
seems that if you land a Vans on anything that
isn't hard and prepared, you end up upside down,
hanging from your harness and most times trapped
by a stuck canopy. Ditching a Vans in water
sounds like suicide, or at least very, very slim
chances of a good outcome. I feel much more
confident in the Mooney's ability to land off
field and in water. I also feel very confident
of the Mooney's strength in the airframe. I'm
not so sure about the Vans.
The wife. I mentioned in passing that I was
thinking of trading the Mooney and she was
ho-hum about that... until I told her I was
thinking of an experimental! She was pretty
strongly against that idea! It will take a lot
of convincing that it is just as safe and I
first have to convince myself.
The wife. The cabin in the Mooney is tight, but
I think the Vans cabin is even tighter. It feels
very narrow to me. As we get older, neither of
us is getting any skinnier. There is also poor
baggage area access, or capacity. While it has
only occurred three or four times in the last
seven years, it would be nice to keep the
ability to take the wife along for a weekend.
I'm not so sure how well the Vans can handle
Money. I don't think I can get anywhere near
enough money for my Mooney to get a nice clean,
well built RV-9 configured the way I want it and
then do all the things that will need to be done
to make it mine. I will have to sell my Mooney
and then likely pony up even more money. While I
have the money and could do this, right now is
not a financially great time for me to do it.

Head hitting canopy fix
The sometime sharp-edged turbulence around the
local foothills has caused my head to hit the
(RV-14A) canopy fairly hard several times, even with
the 5-point harness snugged up tight. The problem
seems to be the location of the lap belt anchors
well behind the seat. While doing a good job of
restraining in the forward direction, vertical
motion can easily be 4-5 inches. The solution seemed
to be an extra lap belt anchored further forward.
I got some seat belt anchors from Van's and located
them about 9 inches forward of the stock ones (see
first pic). The mounting would have been simple
during the build, but out on the tie-down, not so
much. The floor beam material is quite thin, so
added an .060 angle and stiffener on the side
opposite the anchors using plenty of pro-seal and
two AN-3 bolts (see pics 2 & 3). Pic 4 shows the
installation with the ratcheting lap belt (wrong
color, but hey...). This has been very effective,
you can ratchet the belt down till your bones bend
and you definitely become one with the airplane. My
head hasn't hit the canopy since and I also really
like the feeling of being glued in place even with
the simple acro I do.

Short Field Practice ...vid.
...and (11) more minutes to get the logbook entry
Tuesday a.m. was one of those cold,
windy mornings in N. Texas that allows for a very
short landing roll on 35 at my home field.
Since I have manual flaps I like to occasionally
(when the conditions are right) dump the flaps right
as the wheels touch to shorten the roll. The
landing roll measured on GoogleMaps later was 698'.
It'll do shorter with less gas and smoother air.
My 'fun rolls' are a cross between barrel and
axial. Maybe 1/3rd barrel - just enough to
keep all the junk on the floor. The G-meter
showed 2.5 in the loop.
The wind was gusting 21kts
about 20* left of the centerline. The burbles
off the hangars make the 35 landing 'dynamic', and
the slightly-rising runway there at the end calls
for a non-standard flare. You can see the
bumps down low. Game face on and always
something to screw up (which I usually do).
hooked up the Garmin VIRB that's on loan and played
with the edit software a bit. Maybe an excuse
to goof off at work for 2min 40sec if you have the
bandwidth and monitor acreage.

much fun you can have in 12 minutes with an RV.

Difficult situation - need help ...jonweisw
A dear friend of mine needs to sell his RV
relatively quickly due to a tragic loss of his
medical related to a very significant,
incapacitating, health issue.
He completed his 7A in 2005 and it has around 600h
on it. IO360-M1B with a Hartzell. Beautifully built
(seriously - he is a former Navy test pilot and the
attention to detail was nuclear-grade) and
impeccably maintained. Always hangared and NDH.
Unsure as to the extent of his recovery and whether
or not he would be airworthy again, he and his wife
have held onto the airplane but have now decided to
sell it. It is out of annual and based at Punta
Gorda, FL (KPGD).
I have advised her that getting the airplane an
annual and therefore airworthy should be a top
priority (it is not safe or feasible for him to do
the condition inspection subsequent to his event).
Do any of you know of an A&P in the Ft. Myers area
who would be willing to do an annual on an RV? The
airplane will be on the market soon, so this may be
a good all-around project for a potential buyer as

Cold (not dead) cylinder at high MP except WOT ...Rick 9A
I’m observing some behavior that I
would like the group’s opinion on.
Setup: O-320-H2AD, 33H Hobbs/19.5H Tach since OH
with new cam, lifters, new Lyc cylinders. Ellison,
standard dual mag (D3000) also OH. Sensenich fixed,
RV-9A. Compressions are 76/80 or better cold.
At full throttle/WOT – 28.5in HG for the most recent
flight - at low altitudes (takeoff), CHT and EGT’s
line up well. EGT’s are in the 1250F average range
for what it’s worth, all rich of peak. At MP’s
slightly below WOT to medium throttle – 27in HG to
20 in HG– cylinder #4 EGT falls by 100F-150F and CHT
for #4 falls by about 30F-40F versus the average of
the other three. The EGT falls fast and settles out
with thirty seconds, CHT takes a couple minutes.
Below 20in HG, all four cylinders come back together
again in EGT and CHT quickly. It is repeatable,
centering around 20in HG MP.
There really isn’t any perceived roughness, and even
in this 27in - 20in HG cold-cylinder range, #4 EGT
and CHT responds normally and consistently with the
other cylinders to leaning, they are just doing so
from a significantly different place. Since I lean
to basically 100F-150F ROP at anything less than WOT,
I can’t say if ranging from full rich to lean
changes the behavior at the transition points. I
believe it’s been occurring since hour 1.5 based on
the data (no high power data exists prior to this
time, <1.5H is all run-in), and there is no
significant metal in the first two oil changes,
suggesting I’m not wiping a lobe.
My first suspect is ignition, looking for one side
of the ignition falling off on #4. I have not done
any disassembly inspection yet, only gross
inspection of the ignition harness - no obvious
ignition leakage or damage to plug wires, and timing
is on target. I did check the intake tube clamps
(thanks Ralph, I should have mentioned it).
My plan: Run the Savvy ignition test in flight, in
various levels of richness/leanness and MP’s. If
it’s ignition, I expect it will show up pretty
clearly, and the diagnostic work from there is
(hopefully) logical: plugs, harness and magneto get
the focus. I’ll probably look at the plugs anyway –
a cylinder running that cold may be generating
deposits that may point at something (one plug not
firing being scuzzy?).
If that doesn’t give any hints, I will confirm my
secondary elements: valve lift, boroscope, pushrods.
Any hints or past experience would be welcome.

already are after just shooting base coat on the

New Builder and Trailing Edge Question
I'm a new RV-14 builder - yes, no 'A' and little
wheel in back . I am working on the rudder and have
a question for the community. Sorry if this was
answered, but I couldn't find any information from
On page 07-09 - steps 1 and 2, the instructions say
to use adhesive to bond the trailing edge. However,
on page 07-10 - step 2, the instructions say "The
trailing edge will have to peeled slightly ...". I
was planning to use the 3M F9460PC VHB tape as
specified in section 5. Looks like the 3M tape is a
permanent bond, so why would we bond the trailing
edge, then attempt to peel it apart again? Won't
peeling the edge apart potentially damage the skins?
Has anyone used the 3M tape for the trailing edge?

It is with great sadness and broken hearts, we
share that Leo Wipplinger (my father) — beloved
husband, father, grandfather, and great grandfather
passed away. Although we mourn losing him, we are
filled with great joy because he now is enjoying the
presence of the Lord, his Savior. We will always
remember how hard he worked for our family, his
passion for the outdoors (flying, fishing, and
hunting), and his love for his family. Leo had a
heart to help those in need. If you would like to
honor him, please make a donation in his name to

RV-10 Doors and Tinnermans
How do you determine..and fuel levels
How do you determine if you have
resistive float senders, or capacitive senders in
I am beginning to calibrate the fuel levels in my
RV9A for a GRT EIS system, which I didnt build, with
a bit of difficulty.
On my attempt yesterday, I filled the right tank one
gallon at a time, noting the reading on the EIS
after each. The empty reading was 4.2 It began to
change on the 4th gallon.
Then, it stopped changing at the 7th gallon, and
read 5.7 each gallon there after. this isnt going to
Resistive usually are just a flat thin metal plate
on the outside of the tank and capacitive are
usually 1/2" thick and plastic with epoxy filled
center. The gauges normally do not read right to the
top and if the sensor was not installed all the way
to the bottom it might not read down to one gallon.
A: Restive senders have
only one wire, airframe is used as ground to
complete the circuit.
Capacitive units that I have seen will have two
wires, sometimes coax, and use a converter box.
A: OK, As far as I
know, I have but one wire.
But..I didnt trace it to the tank.
The craft had the standard Vans 2 1/4 round fuel
gauges in it. they seemed to work ok in the 75 hours
I flew it before I started the GRT upgrade..
IF I understand this GRT EIS fuel level calibration
correctly, They recommend using the reading for full
tanks as the level where the float sender stops
changing..and the empty reading as the level it
stops when going empty..in my case, it seems that I
will have an empty reading at 3 gallons, and a full
reading at 7. hmm..as I said, thats not going to
work for a 16 gallon tank.
I went thru the math several times on the GRT
Im scratching my head. If the sender output stopped
increasing after the 7th gallon added...I guess it
could be faulty..hard to believe it would only have
a 3 to 7 gallon range of motion. (if its a float)
aircraft was level sitting in the hanger.
A: First, check the
wiring. You should have a wire from the regulated
power (4.7 volts, I think) going to a resistor (470
ohms). The other side of the resistor is connected
to both the EIS input for fuel level, and the center
terminal on the float gauge. The other side of the
gauge should be grounded locally.
Turn off the aircraft master switch (power off).
Disconnect the wire from the float gauge center
terminal. Put an ohmmeter on the center terminal,
and measure resistance to ground. It should be
somewhere between 30 and 250 ohms.
If all this works, there are several ways to trouble
shoot. My guess is on the wiring.
With the wire still disconnected, but not shorted to
ground, turn the power on. Put the voltmeter on the
disconnected wire and measure the voltage (other
probe on a good ground). It should be 4.7 volts. If
not, there's a wiring problem. With the same setup,
carefully hold a 470 ohm resistor between the probes
(while still in contact with the wire). You should
see the voltage drop in half, to, 2.3 volts or so.
If grossly off, you don't have a 470 ohm resistor on
the other end. You'll need to find it and replace
Finally, if you suspect the sender:
Drain the fuel, then start adding it back into the
tank. Measure the resistance each time you add fuel.
You should see it smoothly go from about 250 ohms to
about 30 ohms (probably stop changing as you get
with 3 or 4 gallons of full). (I might have it
backwards, 30 to 250? I forget.)

SB 18-02-02 PIREP ... scottmillhouse RV-12
Just finished this up today and it probably took
closer to 16 hours than 6. I prepped, primed and
painted all parts before disassembly of the tail. No
real pitfalls until reassembly.
Then spent hours getting the pivot bolts and spacing
washers in. The newly boxed in structure makes
access much more challenging and only from
underneath. Connecting the stabilator cable
tensioner solo is extremely challenging but I
eventually worked out a way to do it solo. Connect
the top, pull the lower cable as far forward as
possible, wrap tape around the clevis body and clamp
lightly with vice grips from the bottom. Insert a
piece of cardboard at rear bulkhead to protect it
from the vice grips. (the vice grips will push
against the bulkhead and lock the lower cable
position) With your right hand use the tail leverage
to match holes by pulling down on the rear of the
stabilator. When aligned insert a short #3 bolt in
from the trim motor side. Then slowly from the right
work in the correct bolt to the right clevis side to
put in the spacer washer and then to the left to
install washer followed by outside washer and castle
nut/counter pin. Probably is impossible solo to pull
the cable tension directly from the clevis and put
in the bolt.
Also plan on a lot of trimming to the top rear
fuselage cap faring if built per plans. The exposed
plates are notched but the notch ends probably 3/8"
farther to the front than the clearance previously
required for the box spar. Bottom is easy, just the

Big Bend - Lajitas Golf Resort & Spa ...tcard RV-9A Trip Write-up
I have a friend, 'crazy Marti'
according to Scott, that is an amateur photographer
and bluebonnet fanatic. We've been talking for a few
years about trying to fly down to the Big Bend area
in Texas that has a different variety of bluebonnet
than what we have in Central Texas.
Ours grow low to the ground in
dense fields, but in the desert they are sparse with
flower stalks that get several feet tall. The stars
finally aligned in 2018 for a 3-day girl's get-away
weekend. The lodge in the park was already fully
booked, and as it turns our that was good luck for
our bluebonnet hunting crew. The option of flying
into Alpine or Marfa and renting a car didn't sound
very entertaining. The winning selection was to stay
at the Lajitas Golf Resort and Spa and land at its
6000' x 100' private airport. Luck was shining down
upon us, and I think we got the cheapest room in the

First oil change - ran into an issue...JackinMichigan
Attempted to do the first oil change on my Lycoming
IO-540 today after 5 hours of engine time (break-in
oil) and ran into a problem. When I got the old oil
filter off, the one that came with the engine (and
it was a BEAR to get off), the threaded brass nipple
that I'm pretty sure is supposed to stay in the
engine came off with the old filter. It's solidly
affixed to the old filter, and there's nothing to
grab onto to try to spin it off. I'm leery of
cutting apart the filter for fear of damaging the
threads (oil and fuel systems are things I try not
to get too creative with), so before I continue I
want to throw this out to the group:
- How do I get this brass nipple out of the old
filter? If that's not advisable, where can I get
- Would off-the-shelf Locktite prevent this from
happening again or is there something better?

RV TRANSITION TRAINING SURVEY ...Dick VanGrunsven
(from the mothership FB page)
It is becoming increasingly evident that the fatal
accident rate for RVs is considerably lower than
that of E-AB aircraft in general. While it is
difficult to calculate exact rates, most accident
analyses show it to be approximately 2-4 times less
than the average. I think that insurance
underwriters would agree in that they more readily
provide coverage for RVs than for many other E-AB
designs. These same insurance providers indirectly
contribute to this elevated safety by requiring a
prescribed level of specific aircraft type flight
experience prior to providing coverage. This is
usually in the form of Type Transition training.
Fortunately, there are a number of highly qualified
TT instructors who offer quality training in various
RV models. This training undoubtedly contributes
directly to lower accidents rates.
Many years ago this was not the case. Builders of
E-AB airplanes either simply became overnight “test
pilots”, or at best could garner a familiarization
flight with some willing RV pilot. “Take the
controls for a while to get the feel of it” and
maybe “shoot a landing or two” if conditions
permitted was a common indoctrination into the realm
of flight test. The thousands of you who have had
the good fortune and sense to receive quality TT
training can most assuredly see the shortcomings of
this methodology. Throughout homebuilt history,
accident rates for “first flights” and operations
during the “first 10 hours” have been appallingly
high. Sadly, for many models of E-AB aircraft, this
reality continues. It is demonstrably better for
RVs. This is due to a variety of reasons, but
superior pilot preparation/training is arguably a
I am inclined to believe that in
addition to the obvious benefit of exposing the
trainee to the unique qualities of a specific
aircraft, the requirement that trainees meet a
stringent “stick & rudder” standard set by exacting
TT instructors yields an elevated level of
competence and refinement. This may be a slight
overstatement; however it is my belief that our TT
instructors impose a higher criterion for pilot
performance than is expected by examiners of newly
minted private pilots, or by instructors providing
biannual flight reviews. If my observation is
correct, we may have re-discovered a safety secret;
better pilots. Not just better prepared to fly their
new RV, but better regardless of the aircraft they
choose to fly.
On this basis, wouldn’t most GA
pilots develop into becoming safer if they were to
receive similar “upgrade/refresher/recurrent”
training? You undertook this type-training because
of insurance requirements, your fellow RV builders
encouraged it, and you possess good sense. Enticing
other GA pilots to take “self-improvement” training
perhaps may be difficult without the specific goals
and motivation you had.
My purpose in writing this is to solicit your input.
If you had TT prior to test flying your RV, I’d like
to hear your comments on the training specifics you
considered most important and reaped the greatest
benefit. To name yourself or instructor is not a
requirement. Obviously, to validate my observations
and opinions as stated above would be gratifying in
light of our overall goal of increasing safety but I
also welcome differing experiences and conclusions,
regardless if being contradictory to mine. We learn
from sharing. If you have suggestions for ways of
encouraging all GA pilots to take upgrade training,
please include them.
I’d appreciate your prompt
response so that I may use this as a basis in
advocating for more widespread TT within the
homebuilt community and beyond. If better pilot
training improves RV safety, we need to spread the
good news to all in GA.

Lycoming Carbureted O-290-D2 EGT out of Family ...snopercod
The saga continues
I watched the carb temperature all winter and never
once saw the temperature get down into the icing
zone, even during an idle power descent on a cold
day. Enough heat is transferred from the oil sump to
keep the carb warm. So I'm confident that my
particular engine just doesn't need carb heat on
descent. (Of course it's there if I ever need it.)
I'm still debating the wisdom of removing the temp
sensor that sticks out into the throat of the carb.
Several commenters have recommended that and they're
probably right. What I have found over the last six
months is that the rearmost cylinders 3 & 4 run lean
at WOT on takeoff with the mixture full rich. That's
probably not a good thing, but to compensate, I pull
back on the throttle a little when reaching 500' and
the EGTs even out. You can see that in the graph
below. It's curious because I would have expected
that with the throttle fly vertical, more fuel would
reach the rear cylinders than when the fly was aimed
more toward the front. I think my next step will be
to drill out the "peppermill" holes I drilled in the
nozzle years ago to provide more fuel to the rear
cylinders. IIRC, they're only #57 now, and in the
photos of the Marvel nozzles, they look much bigger.

So far, I’ve tried about everything and still having problems.
New battery, new cables, new master and starter solenoids and took
starter to local armature shop and they say nothing is wrong with
starter, yet I am still experiencing same problem. I’ve cleaned and
reconnected all connections. After 2-3 blades, the bendix kicks out.
Motor continues turning normally, but Bendix disengages.
Occasionally, I’ll get 6-8 blades before it kicks out.
Today, after changing cable from starter solenoid to starter with
#2AWG welding cable and new heavy terminals voltage drop during
cranking was 0.4 volts from 12.5 to 12.1V . Voltage drop on ground
side was only 0.15V.
Despite what armature shop says, I think I have an internal starter
issue. I guess next step is a new starter. My starter is a

RV-3B Construction PIREP ...David Paule
I finally reread the manual for the areas I've
been working on. Should have done that earlier, as
it would have told me the correct way to assemble
that spar bulkhead strip that I had to unrivet. The
manual says "The rivet holes through the skins and
the bottom flanges of bulkhead F-303 should not be
drilled until both skins are in place."
I agree with this with one exception: if you drill
through the bulkhead flanges first, then when the
skins are in place, you can back-drill through the
skins using a 12" bit, and there will be no
difficulty locating the holes on the skins. Just
watch out for edge distance when you're locating the
holes on the flanges and when you set up the skins
Also, note that some of the rivets are -4. When
you're doing the drilling, if you don't go bigger
than #40 at this time, you'll save yourself some
time. You can drill those holes to #30 before
dimpling. Just don't forget.
I glued the strip on to the flanges. That'll let me
remove those clecos during the fitting of the
forward belly skin.
A machinist friend made the button at the end of the
manual flap handle and cut the slot. The bearing
blocks for this are ready now, too. The plans don't
show it but the manual correctly says to install
nutplates under the bearing block mounting angle to
facilitate easier maintenance. Since my seat rib
flanges were running low on edge distance (the
extruded angle is ample) I made a small plate to
rivet the nutplates to, and then riveted the plate
to the frame. The other side is complete too.
New (March 2018) Garmin GDL 50/50R ADS-B Receivers ...g3xpert
are pleased to announce the Garmin GDL 50 portable
and GDL 50R remote mount ADS-B receivers that are
capable of receiving Automatic Dependent
Surveillance-Broadcast (ADS-B) traffic and weather.
Both units also provide built-in attitude sensors
and a GPS receiver. The GDL 50 includes a built-in
rechargeable battery which provides battery
operation for up to 8 hours. While battery and "3D"
attitude was optional on the GDL 39, these features
are standard on the GDL 50.
Exclusive traffic features such as TargetTrend™ and
TerminalTraffic™ further enhance the ADS-B traffic
picture and are unique to Garmin products.
Wireless and hardwired compatibility is provided for
G3X™ Touch, the aera® 660 and aera 795/796 aviation
portables, as well as wireless connectivity with the
Garmin Pilot app, giving customers access to a
full-featured suite of weather products, ADS-B
traffic and more using a single device.
Each of these receivers supports 2 wired (RS-232)
display connections and 2 wireless (Bluetooth)
display connections for a total of 4 display
One of our most popular G3X Touch installations is
one with dual displays, and with the GDL 50R/51R/52R
we can now hardwire the RS-232 interfaces to both
displays, and leave the 2 wireless interfaces
available for portable units.
If you already have a GDL 39 interface mount/cable
for your Aera 660/795/796, you can plug it directly
into the GDL 50/51/52 since these units use the same
connector/wiring as the GDL 39 for power and data.
The GDL 50/50R are the latest additions to the GDL
50/51/52 line of ADS-B and SXM traffic/weather/music
GDL 50/50R with ADS-B Traffic/Weather, attitude, and
GPS (Availalble now for $849)
Trying to wrap my head around this .. p45-05 fig 1 ...bkervaski
On page 45-05, fig 1, the exploded view shows an
inside corner line that calls for an angle that
doesn't make sense to me.
I'm looking for some clarity, as this cut would seem
to result in a triangle opening in the cowl and
omitting it will have both cowls mate evenly.
Confused. Edit: I found this pic (not mine,
it's on E's site). This is correct? Is there an
obvious reason for the triangle cut-out I'm missing?
Stress relief perhaps?
Fiberglass Painting Tip ...Carl Froehlich
Don’t forget fiberglass and ultraviolet light do
not mix well. Put something on it.
This is what I do for flying before final paint:
- Prep all fiberglass to fill pinholes per the Van’s
- White two part epoxy primer on the inside of the
cowl (e.g. PPG DP48LF). Two coats. Do this before
first engine start.
- Van’s stick on aluminum heat shield on the inside
of the cowl in the obvious places (check for
discolor after the first few flights and add as
- One coat of PPG epoxy primer on outside of the
cowl and all fiberglass.
- One coat PPG single stage paint in your choice of
color on top of the primer. I find a medium blue
goes well with the rest of the plane in bare
- Anything you can do to prep the glass will be
appreciated by your painter (especially if that
painter is you). He might even drop the price a
little as he’ll see the PITA fiberglass prep is well
started. The primer and top coat paint will also
give the paint guy material to block sand - that
will only improve the final product.
- Even though you plan on painting right after the
flight test program, odds are you will be flying
like this for some time. The simple extra step of
adding a coat of color on the fiberglass will make
it look worlds better.

We've had some
damp Wx lately here around the 'ol Van Cave, but by dumb luck
there was a gap between rain bands when I pulled into the airport
Wednesday morning. My planned 45 minutes on the treadmill went
out the window. As it should.
(15) TnGs later I felt much better. Didn't have the ceilings or
clear skies to venture beyond the pattern, but it was plenty fun to
just work on technique.
Then the rain started...and it didn't stop for the rest of the day...and

RV-14 Milestone ...control
Standing on wheels...
I received a text from my 25 year
old daughter this morning asking if I would have the
40 hours for my phase 1 flown off by July. I told
her I have about 25 more to go before I would be out
of phase 1. Circumstances, weather, wind and the
distance to the airport have hindered the progress
of getting those hours flown off. She said she was
asking because she was wanting to take the time off
from work so she and I could fly up to Oshkosh for
Airventure together. She and her husband moved away
from us this last year and its an 7-8 hour car ride
each way from Kentucky to her home in Springfield
MO. I figured its about 3.5 in the RV one way. I
know her mother is wanting those hours flown off as
well. I don't think she (my wife) was a big fan when
I started the project.

Winter Ops PIREP/Question ...martinair
yesterday was probably the coldest day for my

-15°C (5F) in FL85, and the oil temperature never
exceeded 63°C (145F). Usually I am keeping that
around 90°C (194F). during descent, even though I
kept the revs up, cyl 2 cooled down to 85°C CHT
question: for the next flight, my idea is I just use
some duct tape, maybe strenghtened with a small
sheet of aluminium, for example on the lower half of
both inlets, to reduce the amount of cool air coming

So, you learn something every flight. Here’s what I
I use Fore Flight to file my flight plans, yesterday
on the way down we had a 4 knot tailwind. We were 2
hour 25 minutes going down. When I filed to come
back Fore Flight used the mornings winds aloft to
calculate the time enroute.
So there I was fat, dumb and happy at 10,500, but
only seeing a 140 mph ground speed. As a result we
we’re 3 hours coming home. When I called London
Radio to cancel my flight plan I got a stern lecture
on being overdue.
Now, this was the same guy I talked to twice for
weather. Once south of North Bay and once North of
Gore Bay. I was on 126.7 which is also the frequency
for London radio for the last portion of the trip. I
had it in mind to update my ETA when I called for
weather at Gore Bay, but I let it slip. My Bad!
So the take away is that I have to update fore
flights weather, before flying a return trip on the
same day. Normally I’m within WIFI when l’m planning
a flight, darn no WIFI at Mo’s.
If I had thought about it I could have used the hot
spot on my phone to update the weather, or I’m
thinking I’m going to try one of those Scout ADS-B
in receivers. That way I will have on board weather
when I’m close to the US border.

Hi Larry ... here's how my bird is coming

to the subpanel. It's secured by piano hinges; the
pins come out the front side of the subpanel and it
simply drops down and can be removed for maintenance

Wing Incidence Problem ...efitzgerald RV-7
I temporarily mounted the wings.
After making relief notches to clear a rivet at the
top of the rear spar stubs, the sweep and
triangulation is less than 1/16" off.
But when I check the incidence with the rear spars
lined up to the bottom of the flange:
The left wing is 0.2 degrees high on the trailing
end at the tip.
The left wing is 0.1 degrees high on the trailing
end at the root.
The right wing is 0.0 degrees at the root
The right wing is 0.1 degrees low on the trailing
end at the tip.
The best I could do was to lower the stub of the the
left wing spar approximately 3/32""
The left wing is 0.1 degrees high on the trailing
end at the tip.
The left wing is 0.0 degrees at the root
The right wing is 0.0 degrees at the root
The right wing is 0.1 degrees low on the trailing
end at the tip.
So it appears that there is some twist to the wings.
Also the flap / fuselage interface is not going to
the same on both side as the left is slightly lower.
Edge distance is not a problem, there is lots of
room. This is a quickbuild kit, the quality seems to
be good other than a lot of scuffs and scratches.
Q: What are you recommendations?
One tenth of one degree is pretty good IMHO. You
would not even see that with an old fashioned bubble
level used by builders pre digital age.
One of my wings had about .2 degrees of twist. I set
the incedence in the center of the wing and guess
what, it flies straight and level with the ball
centered. A tenth of a degree is nothing. One of my
flap skins also has about a 1/8-3/16 joggle to meet
the bottom of the fuselage.
A: I seem to
remember this in a search. Basically the consensus
was make them both the same at the measurement point
in the plans. I did ask about sweep and was told
make them the same. A call to Vans would be prudent
before drilling the rear spar holes.

I needed the dye to see it. In fact, I missed it the
first time with the dye but was not satisfied with
the developer cover, too thick I thought. Since it
was a tight area, the spray dye was too much and is
probably still wicking down the spar toward the tip.
I did spray it lightly.
The next 3 or 4 times I wiped the dye on with a rag.
Wiping on seemed effective as long as I kept the
surface wet. Cleanup was much easier.
Once I knew where the crack was, I could see it with
a 10x loop or use the macro setting on the camera. I
could not have found it without the dye.
I tried it four times instead of three because when
I wiped the third test, I could see the crack but
could not see the end. On the fourth test, I center
punched the spot with the dye and developer still
showing the end, I hope.
The servo tabs did not present a dye indication.

In Regards to Sideslipping RVs
No one has really explained why slipping may
become a problem and why you probably got the
First of all they slip well. However, depending on
how the fuel tank was built and how much fuel is in
the down wing could lead to an engine stoppage.
This happened in our RV-9.
If your down wing tank has flop tubes this is
unlikely to happen as it will still be able to pick
If the down wing tank has a standard pick up tube
and it is low on fuel the fuel flows away from the
pick up in the down wing. Of course it will take a
few minutes for the carb to empty but FI may be
affected by it pretty quickly.
So if you are going to slip, make sure either you
are on the raised wing fuel supply, have plenty of
fuel in the down wing is still taking fuel from that
tank, or there is a flop tube in the down wing.
In our case the engine restarted soon after the
wings had been leveled but the pilot got a nasty
surprise when it stopped initially and then again
when it started making power again.

Need help w/Fuel tank sender possible weeping screw
the first annual since putting this rv6a back
online. There were no apparent leaks before this,
but this year’s annual revealed some blue staining
around the sender after I took the wing root fairing
off. It appears to me that the leak is just a
weeping screw based on the pattern of the stain and
the gummyness of the pro seal around that screw.
Then again, the pro seal that has been touched by
the fuel is also soft enough that I can scratch it
off with my finger in places.
If it is the screw, can I just drain the tanks, wait
for it to dry, and apply some new sealer after
scraping the old stuff off? Is there anything else
that might work better for this application than
proseal? Wicking loctite?
Or does it look like I’m going to have to pull the
tank and remove the sender and do the whole thing?

12”long (vertically oriented)x 3” diameter pvc pipe.
I screwed one end cap to a board, then glued the
pipe to that, with a threaded end cap for the top.
On the base, I tapped in a brass fitting for the air
from the pump, and filled tube with blue desiccant
that turns orange when saturated. Off of the top
cap, I tapped in a air tool filter/dehumidifier as a
final filter, and tell tale for the desiccant inside
the tube (the filter from harbor freight also has
the blue desiccant visible). From that filter I put
a barbed adapter to connect the plastic airline to
my engine oil breather tube. It continuously pumps
dry air through engine.
Comments??? Concerns??? And, no, I don’t have my
breather tube notched.

Weekend with the Grandson ...MarkW

RV-12iS forward lower fuse mating problem ...B.Collins
I wonder if there are supposed to be two more
slots on the forward end of the mid fuselage skin.
When you make the lower forward fuselage, there are
two large -- for want of a better word -- ribs that
rivet to the bottom skin and the firewall; these
also hold a engine mount bracket/gusset.
You don't rivet the most aft hole on each, though,
because those are common to the mid-fuselage skin

This is some damage from a

was not repaired even IF its non structural and
deemed air worthy.

for battery powered operation using the internal battery pack. The
Micro-Trak can be operated off any clean external source of DC that
does not exceed 13.6 Volts." It uses a little battery

Transition Training with Mike Seager
Just got back from 3 days of transition training
with Mike Seager. I'm in Alabama, he's in Oregon, wasn't sure it
would work but SouthWest had $330 flights so I booked it.
I highly recommend his transition training. We spent 6 hours flying
and as you can imagine it was mostly pattern work.
At the very end he turned off the EFIS and had me rep the pattern
without any avionics which was a lot of fun and some of my best
approaches and landings.
We did a simulated engine outs, etc.
His field is a grass strip and my first takeoffs and landings off a
paved runway (rental companies won't let you land on grass strips).
Most of our work was done at a nearby paved airport.
Mike is a wonderful person and a patient instructor, wish I had an
excuse to go back for more. Loved the work and the visit!
Highly recommended, 5/5 stars.

One Cylinder Suddenly Runs Cool?
IO-360 (200HP - Bendix) in the
RV-8. Engine was misbehaving with a little
intermittent misfire on a recent cross country, so I
installed new plugs (gapped and Ohm checked) and
removed the Pmags for a visual inspection and it is
timed correctly. (jumper in, slightly retarded). Did
a compression test and all are strong, as usual.
Test flight saw an improvement to its normal,
turbine like smoothness.
Last cross country saw #4 cylinder a little cooler
than usual - both EGT and CHT. Going to my normal
LOP cruise, #4 continued its trend of acting too
cool by being the last to peak by a LONG way. My
first to peak was 100 LOP before #4 finally peaked.
The "GAMI Spread" was probably .8 GPH. LOP ignition
stress test was normal and smooth. Resetting all to
ROP then LOP shows the issue is consistent and
repeatable. Fuel flow is within the bounds of
I have not accomplished a fuel flow test (the bottle
method) yet, but that's my next course of action.
If the cylinder was acting lean, it would be easy to
suspect a partly clogged injector, but #4 is

this one cylinder. It's possible that the other 3
have junk in them and are all slightly lean, but
this seems very unlikely.

Proof of RV Enjoyment…glove edition
The Nomex flying gloves on the right were used
exclusively until about two years ago. You can see
the tear on the right index finger which corresponds
nicely to the friction lock on the throttle of our
family’s RV-6. I've actually spent so many years
adjusting the knurled friction knob with my right
index finger, putting side loads on it, that I have
accelerated what I believe to be arthritis in the
knuckle of that finger. I've had to adopt a
different technique for the last year or so of
holding the second and first fingers side-by-side
and using them in concert to lock down the throttle.
The pair of gloves on the left (the replacements)
had their first thread blowout about three weeks
ago, and the hole has been getting bigger with each
flight. The 3rd set of gloves arrived yesterday and
things are looking up from a hand modeling
perspective...for a couple of years. ;^),

I purchased a new creeper as my old one is getting

I could mount the frame upside down. Now the
bed is up higher than the castors rather than
hanging down inside the castors. The holes in the
frame have square holes to keep the head of the bolt
from turning and by putting the frame upside down
you have to hold the head with vise grips but so
what. Been using this set up for quite a while and
makes working under the engine or fuselage much

It may start with a particular type of takeoff, then
some various types of practice during a long

routines, then a multi-step descent with various
maneuvers during a step down, etc, until landing.

Gary's Hud Testing
Gary Platner was helping a company test a hud for
GA in his RV-8 Thursday at 52F, and the rep gave me
permission to take a photo. Shot video in
flight for the coders to use for tweaking.

28.9*F and windy said the
APRS Wx station three
miles north of 52F Tuesday morning, but I went RVating anyway. Long
johns, Red Wing boots, two coats and winter motorcycle gloves.
Actually wasn’t that cold in the cockpit. Big bumps at all
levels. Did I mention the
wind at 2700’?
So I did what anybody in that situation would do…..I flew north a
few miles and turned around so I could use that massive tailwind to
a picture, in level flight, of my 201kt groundspeed. Then
I landed, found a heater....and took an aspirin.

I did a thing! (Restarted Building RV-7) ...Andrew Z.
(walks up...taps microphone...)
Well, I’m back!!!
To make a very long story very short, back in 2013,
I sold the RV-7 kit to a gentleman in North Carolina
after reaching the conclusion that at my (then)
current build rate, I would likely need a four-seater
Well, after a smooth transaction, the family and I
made 3 cross-country moves chasing fun Flight Test
jobs around the country and finally settling
somewhere in the midwest.
Standing in my large garage (ahem….airplane
factory), I started dreaming about building again.
On the exact same day, the gentlemen who bought my
kit happened to post a FS: RV-7 thread on VAF. I
didn’t really want to start a used kit, so I was
thinking of a new set of preview plans, but I
thought I’d investigate anyway.
Whoa, that’s my kit!
Wheel landings FINALLY
After flying my Husky for 1000 hrs and 2000
landings I am finally getting proficient at wheel
landing my 7. It took a while as I am used to BIG
tires and slower speeds. The RV landing gear is just
so less forgiving and I kept bouncing it. Just took
a little time to get the sight picture correct and
the speed just right. I was three pointing it most
of the time and the wheel landings are just easier
on the plane in my opinion. I read through the past
discussions on this topic and i really helped a lot.
Jumped in the 7 and did at least 50 landings this
past weekend. The key is getting the mains planted
and stick forward. These plans are just plain fun to
fly. Got it to 17500 on oxygen and I was amazed how
fast it got these. Looks like I am stuck with two
plans as I cant decide which one I like better.

I was going to write something about RVs,
but after watching the launch of Falcon Heavy
YouTube around 3pm Tuesday my mind has honestly
been elsewhere. When those two boosters landed
simultaneously I actually screamed out loud at my

Pantaloons were very nearly shat.
I was four when Apollo 11 launched, so this was a lot of fun to watch.
The live telemetry, music and employees cheering in

Later I popped over to RV-7A/12 builder Bob Collins' 'News

they are reading this, congrats! I would

The mission for the airplane is simply VFR Day /

is supported by steam gauges for Oil pressure and

by the engine and the Airspeed and Artificial

flying at night a power loss is a non issue as you
can safely navigate.
Eagle's Nest Projects - Montgomery High School (TX)
(comments from Ernie)
"Take a guess who has the most fun and/or rewarding
experiences during an Eagle’s Nest high school
aircraft build project; the mentors or the
build-students. Well, it really depends on who you
ask. Ask any build-student and they’ll certainly
convince you that the students have the most fun and
best experience. Ask any mentor at Montgomery high
school or any other Eagle's Nest high school and
they’ll more than convince you that the mentor team
has the most fun and offer up a list of reasons why
the experience is among the most rewarding in their
life. And the correct answer is… it’s a draw!
mentor team at Montgomery high school is a
top-drawer group of professional pilots and RV
builders based “on top of the hill” at nearby
Conroe-North Houston Regional Airport (KCXO). Under
the leadership of Joe Waltz, the mentor team has
taken to task the largest group of build-students
(48) at any of our high schools. The ‘team’ is doing
an outstanding job of organizing the students, the
build process, and through it all an excellent level
of build quality. Build sessions at Montgomery high
school are two days per week with two back-to-back
50-minute class periods of 24 students each. Their
current build-project, EN-19, was started at the
beginning of the 2017-2018 school year and is on
track to be completed and on display at Oshkosh this
year. Just mention “aircraft build” to any of
Montgomery’s 1,600 students or staff and you’ll be
greeted with a response filled with pride,
excitement, and an invitation to visit the build
Mentor debrief sessions at Montgomery are typically
held at one of the local burger joints immediately
following each build session. I’ve attended several
of these debrief sessions and it reminds me of a
bunch of kids in a candy store; smiles, laughter,
and never-ending stories about the really cool or
absolutely unbelievable experiences each shared with
their students that day. Two of my favorites stories
are (1) the ‘engineering’ student that didn’t know
how to read a ruler and the mentor’s experience
through the teaching process and (2) the student
that didn’t know what a saw horse was. I found the
saw horse story a little hard to believe and it
prompted me to ask our waitress if she knew what a
saw horse was. After a long wide-eyed blank stare,
she timidly said no. Confirmation that today’s youth
need a little less ‘screen’ time and a little more
Eagle’s Nest Projects is the most successful and
prolific high school aircraft build program in the
USA. Seven and one-half years- 14 completed (flying)
aircraft and 7 aircraft under construction at
various high schools. Build projects are implemented
as a companion lab project to existing STEM based
engineering curriculums (ex. PLTW Aerospace) and the
builds take place in the classroom lab area during
regular hours. Students are graded, most receive
dual academic credit, and above all, students are
held accountable for attendance, conduct, level of
participation, and knowledge base.
Community and education partnerships are the
supporting pillars of the program’s success. Eagle’s
Nest Projects is partnered with Project Lead the
Way, the nations leading provider of STEM
curriculums, Embry-Riddle, the nations leading
aeronautical university, and with a number of other
aerospace and engineering-based education
organizations. Community partnerships include school
districts, municipal airports, local businesses, and
hundreds of individuals who volunteer their time as
mentors. If you missed it in the above captioned
video, ABC Channel 13 News was so inspired by the
great work at Montgomery high school that they
reached out to Southwest Airlines and announced in
the video (surprise to us all) that SWA has offered
their support and intern opportunities to Eagle’s
Nest build students. When you think it just can’t
get any better, a new community partner joins in
support of the program with new and exciting
opportunities for Eagle’s Nest build-students to
further empower them on a pathway of leadership and
a productive life."
When Worlds Collide ...Scott Chastain
On Saturday, January 27, 2018, I got sent to the
old Fritzsche Army Airfield, now the Marina
Municipal Airport (OAR), where I got out and looked
around. The place felt abandoned. Nobody was around.
I put the canopy cover on as the morning sun began
delivering the promise of heat across a tarmac that
at once held history in its structures while a light
breeze sighed vacantly beyond.
Trim Selector Switch & Indicator ...GalinHdz
Back in 2012 when I designed my all glass
instrument panel, I thought I had covered every
possible situation you could encounter while flying.
I was quickly proven wrong when I did my first
flight with my wife. As we flew along she rested her
hand on the co-pilot joystick, and since both
joysticks have trim control, she accidentally
changed the way the airplane was trimmed. Since I
fly actual IMC, this was not part of an acceptable
design to me. So I re-wired the trim circuit and
installed a trim selector switch. This way the trim
can only be controlled by the pilot flying while the
other trim is inactive. This setup worked to
perfection, until last month.
I was flying with a pilot friend who wanted to do
some practice approaches. He flew the airplane for
about 1hr then it was my turn to do some approaches.
But no matter how hard I tried I was fighting the
airplane and could not keep it where I wanted. After
about 1/2hr I realized the trim switch was still set
to co-pilot so no matter how much I moved the trim,
nothing was happening. As soon as I turned the
switch to pilot, I could properly trim the airplane
and everything fell in to place. I realized that
unless I was looking down at the selector switch I
couldn’t tell who had control of the trim. The last
thing I want to do while flying actual IMC is to be
looking down to check the trim selector switch
position. Again this was not part of an acceptable
design to me. So I went back to the drawing board to
come up with an acceptable solution. The process is
too long to post so here is a link to a .pdf file
that details my "solution".

Closest thing to a hug ...Steve M.
"...a pat on back is close to a hug.
I took off at -10C at 5PM. A Cessna 320 was inbound
and I knew the voice. Hey, Bob how's it going, chit
chat. Upon him entering the pattern, I heard "Steve,
I can't get my gear down". He was returning from the
Avionics shop that had installed a L3 and new audio
panel. I asked him to join me perpendicular to field
at 5 miles to have a look. The gear was up. He began
to crank the gear down manually for his first real
situation. I verified it was down. He swung a 180
and landed uneventfully and then stopped over at my
hangar afterwards. I got a pat on the back but it
seemed like a hug.
This is the same avionics shop I walked away from a
couple of years ago because it didn't seem focused.
Even for a transponder check.
Why was I flying when it was so cold, -14C at 3000
ft. Why was he inbound at exactly the same time I
lifted off? Why was it a perfect execution? He is
trained and he flies angel flights. He mentioned it
felt good to have someone there."

a handle on "good enough." Two quick questions:
1) Scratches. These were caused by the squeezer

prepping to paint, something to buff out and prime
over now, or absolute death to the part?

Over Dimpling? Any answer to the original question?
cant seem to find an example of over dimpling. I
keep reading over and over its hard/unlikely to over
dimple but in another thread I was discussing my

under dimpling could be the cause. I went back over
some holes and hit them pretty hard with a hardwood
flooring hammer and the c-frame on the concrete
floor. To me the dimples look crisp but from a
distance the whole row looks rippled. I think it may
be what the OP was trying to describe. Its very hard
to capture the ripples on camera.

I have about 900h on my RV-8 with a Lyc IO360M1B,
which was installed new with the airplane. Nine
months ago, I upgraded my panel to dual G3x's from,
among other things, the Grand Rapids EIS system.
At about the time that I was testing out my new
avionics, I noticed occasional fluctuations in fuel
pressure, from a baseline of about 24psi to
momentary lows as much as 14-15psi. The dips were
transient, occurring maybe once or twice per hour,
and not associated with any changes in engine
output, RPM/MP, or sound/tone. They seemed to happen
at higher altitudes during prolonged cruise
(6-9000'), but were not associated with temperature.
There were no changes in fuel flow. Activating the
Aux Fuel Pump remedied the low pressure without
hesitation or fail. It is possible that this was
occurring with the EIS system and that I missed it.
I decided to have the fuel pump replaced before it
failed outright. Upon removal, there was nothing out
of the ordinary; no debris, no leaks, no undue
chaffing or obvious wear. I did not take the pump
apart to inspect the diaphragm.
The new pump is generating 32-34psi consistently,
hence confirming (to me at least) that the original
pump was in slow failure mode.
I was under the impression that these pumps rarely

discussion. I fully intended to fabricate a copy of
the steel Tail-Mate but decided to first whip

Old Farts Update ...turbo's 1/28 entry
Our trip to Arcadia (X06) worked out wonderfully!
The weather cooperated with winds coming straight
down Runway 06, mostly sunny skies and tolerable
temps. The big winds held off until we were all back
in our hangars. Our hosts, George Chase and his
Friends of Arcadia Airport, again went above and
beyond to make sure we had everything we needed for
our cookout. Randy and Beverly Barry, owners of
Eagle Vista Aviation and operators of the X06 FBO,
went out of their way to make sure we were welcome.
They shuttled Old Farts from the ramp in their golf
cart and offered up tours of their agricultural
aerial spraying training facility. And finally, as
an unexpected treat, we were allowed a look at an
incredibly rare Antique Aircraft based at Arcadia.
What a great day! Oh... I counted 31 Old Fart
aircraft and we went through sixty burgers and six

An Unexpected Builder Risk - Radon
Here in this part of Colorado, we often have high
levels of radon in our homes. Radon is a radioactive
gas that comes out of the ground under our homes.
Relatively low doses are a risk for lung cancer.
Getting rid of it takes a straight-forward bit of
work, which I won't go into, except to mention that
it generally includes a suction applied below the
house to exhaust the radon before it can enter the
You can see a map of the U.S. that shows relative
levels across the country
Click on your state for a closer look by county.
Radon can't be detected except with a radon tester.
There's no smell to it.
My neighborhood association has a radon tester and I
borrowed it. It spent a week in the unfinished
basement, a week in the main part of the house, and
a week in the shop, otherwise known as a garage
among people who aren't building airplanes there.
Since I've been spending 500 to 600 hours a year
there, it seemed a good place to check.
The results are in picocuries per liter:
8.8 in the basement,
8.6 in the house,
and 17.9 in the shop.
What's the risk? I'm a non-smoker, and the numbers
get much worse for smokers. But at a level of 8,
about 15 people per thousand could get lung cancer.
Out in the shop, for me, it's probably twice that.
But catch this: there is no safe level! But EPA
recommends getting it fixed it it's over 4.0, and
even there, the risk is about 7 people per thousand
getting lung cancer.
I've got to get quotes and get this thing fixed, for
sure. Especially since now it's out on the internet.

Gap around flush rivet mfg head
started my project with mainly used/borrowed tools
from a friend and have been adding tools of my own
as I go along. The dimple dies I was using were
giving good results but they have built a whole
airplane already and I figured why not get a new set
of my own. I bought the Cleveland spring back dies
to use on the skins. I also bought a set of the sub
structure dies just to try it out. I tried on a
scrap before going to town and everything appeared
to look good. I went ahead and dimpled real parts
and during assembly I started noticing a slight gap
around the manufactured head of the rivets that I
wasn't getting before with the old dies. I pretty
concerned so I took some scrap, made a test part,
and took a cross section of the joint on a wire EDM
machine I have at work. I think the joint looks OK
(other than the shop head being a little off) but
you can see the little gaps around the head. It
looks like the new dies leave a larger radius and is
the reason for the gap.
What is everyones thoughts on the gaps I am seeing?
Could there be a different reason this is happening?

January 24th, at high noon, N25SR, a Murphy Super
Rebel, SR2500, took to the skies for approximately
45 minutes. I could not have built this airplane
without the incredible resource Vans Aircraft Forum
provided. I purchased all of my avionics from
individuals on the site, many of my engine
accessories and wiring tools, swapped a set of
incorrect Lord mounts with a Harmon Rocket builder,
and even learned how to build my own panel with an
excellent pin out diagram from Stein. I even managed
to wade through the many controversial topics
documented in the database, and made informed
decisions on priming and Pro-Seal application
techniques. And perhaps most important, I made
numerous friends through contacts on this forum, and
then had the chance to put faces on at Oshkosh,
where I volunteer in homebuilt camping.
I bought the kit in 1995, took delivery in 2000 due
to overseas USAF moves, finally retired and began
construction in 2011; finished a Cygnet; built a
hangar; designed, built and began marketing the
Pedal RV; restored another Cygnet; and then, after 7
years and 4000 hours, it all came together. Empty

The flight was relatively uneventful with only a few
minor discrepancies. Notably, the airplane was
really fast and I wasn’t able to get it up to the
75% power range for adequate engine break in
procedures. I broke ground within the first 600 ft
and was almost immediately into the yellow range of
airspeed. We had cloud cover at 2500 ft limiting my
ability to climb. Consequently, it wanted to go too
fast and I had to throttle back more than I wanted
for the chrome cylinders. I’ll wait for clear skies
on future flights. No adverse handling
characteristics and I’ll pat myself on the back --
awesome landing. It’s going to be a real performer.

Slow-Build Wings ...Dr. HC Phillips RV-14
I started building my slow-build wings around
mid-May last year. At the time I had just completed
my empennage after about 5 months of effort. Based
on that experience I (laughingly) thought I would be
done with them by this past Christmas, or about 7
months of effort. I am now about 8 months into the
wings and have only gotten this far:
I'm at the step where you rivet the outboard
leading edge to the spar assembly. 8 months and
there is still so much to do before the wings are
finished-fuel tanks, pitot, wiring harnesses,
aileron trim, aileron servo, magnetometer, flaps,
ailerons, and bottom skins. At this point I'm
thinking it is entirely reasonable for it to take a
full year to finish them. I'm curious; am I just a
slow builder or do the wings really take this long
to finish for most folks? I'm 15 months into the
build and I estimate I have about 600 hours in the
total project. Those are actual build-hours. I don't
include head-scratching, cleanup, or other putzing
around the shop hours. How much time/effort has it
taken you slow-build guys to finish your wings?

High Temperature during take off in RV-7 ...givo in Italy
I guess this issue has been
already discussed many time in this forum .
Nevertheless I’m relatively young in experimental
field and in RVs so I post the following question ,
hoping someone is so nice to give me some suggestion
I have problems of temperature in my RV-7 180 CV . I
have two CHT , one on the most cooled , one on the
least cooled cylinder .
I have also a small door on the lower cowling ( I
miss the English term , in Italian is “ flabello “ )
that can be open with a servo .
With this door open , during take off also in winter
with externa temperature of 30 – 50 F° , the
temperature of the less favorable cylinder goes from
350-400 °F to 450 °F . The other more cooled
cylinder will stay around 400 °F .
After take off I usually level the aircraft quite
soon reducing power as soon as feasible and until
both temperature return to 350 F° but it take quite
a while .
Than I resume normal level flight at 75% power .
From now on temperature are relatively stable around
350 °F but if I start to climb also starting from an
altitude as 3000 ft the temperature of the less
favorable cylinder goes to 400 ° F .
Question : there is a way to improve ventilation
inside the cowling ? Shall I install second door on
the lower cowling ? or may be shall I enlarge the
bottom opening ? regarding the baffle they seems to
sit quite tight with the cowling … tank you for
suggestions … Giulio

Thoughts RE: the Thermal Expansion of Plexi ...AlexPeterson
re-read this thread, and have some thoughts.
It seems we've been discussing stress concentration
factors, which are typically used when, for example,
one places a strip of material containing holes
under tension. The stress is "concentrated" around
the edges of the holes in the manner depicted here:
However, this does not fit our situation entirely.
The above depiction assumes the tension is not being
applied directly on the edges of the hole. In the
case of canopies attached entirely or partially by
rivets, once the acrylic has contracted enough to
contact the rivets at the extreme ends, the force is
applied at the hole. We now have a local contact
stress which may be extremely high.
Bill's interesting test of attaching a strip of
acrylic to a steel angle might have a different
outcome if the strip were wider, yet still attached
in the same way. The resulting force on the fastener
will be proportional to how wide the strip is. Our
canopies are really wide, as analogized to this
I guess for me, what remains a mystery, is why they
don't all crack... When I take mine from a 45F
hangar out into 0F or so weather, the clicking it
makes is horrifying, once the engine is running and
the rapid cooling begins. The clicking is presumably
the acrylic shifting relative to the frame, as the
mounting scheme was designed to allow. If it stops
clicking I need to worry.
It has been doing this every winter for 1600
hours/16 years, and hopefully it will continue to
behave. The -8 is obviously worse case, given its
length and the apparent mis-match to the curvature
near the aft end.

Low time Pilot, New (to me) RV, motion sickness
Hi All, long time lurker here, only a couple of
I received my recreational cert. back in 2012
(Australian equiv of a sport pilot i suppose).
My 1st flight was in a Fly Synthesis Texan, on a hot
bumpy day. Another student on the ground before my
flight said, "Don't throw up!". We got into the
circuit started doing basic effects of controls etc.
I'm getting greener. I said to the instructor, "i'm
going to spew!" He handed me a towel and I used
that. Nothing actually came out of me, just a big
burp, was a strange experience. We landed, and I
called it quits for the day.
I ended continuing my training, and it took me,
according to my logbook, about 19 hours to go solo.
I battled air sickness the whole way. I then
completed the endorsements I wanted (cross country,
radio, passenger etc).
My instructor was(and is) convinced its all in my
head. I, to a point, agree. Sometimes I would feel
sick before we were even airborn. It was never a
case of being nervous about the flying or the
landing. I knew I could land it, fly it,
navigate etc. I was afraid of being sick.
I kept flying for another year or so in a rented
aircraft, which was a ICP Savannah with a very light
wing loading, STOL kind of aircraft. Probably not
ideal for our climate. Hot, humid, bumpy etc. Then
work rosters and things changed, didnt have time to

of 60 hours total time.

Went for a short flight with the owner, and again
its the middle of our summer, hot humid and bumpy,
After 15 mins, I'm asking to go home. No vomiting,
just the sweats and queezy.
I know it has been a considerable amount of time
since I've flown, and I'll never be an aerobatic
king, but I'm stubborn and have wanted an RV ever
since I found a stack of sport aviation magazines in
a secondhand shop when I was a kid.
But now I'm thinking I've made a mistake. More then
anything, I get angry/disappointed/ashamed about
being sick, and disappointed that I cant enjoy what
has been my passion since I could talk!
Sorry for the long winded post.

Flat Tire Update ...airguy
My new tires and tubes showed up
so I jumped into the task today. I had a little
damage on both main wheel pants from pulling off

flat tire side, nothing some touchup paint won't
solve. Apparently I picked up some piece of debris
on the takeoff roll or very shortly before, in the
wheel pant that cut the sidewall of the right main
and got through it to the tube. I did not find the
offending piece of debris, just the evidence of it's
passage. I replaced the Vans OEM tires/tubes with
Desser 6-ply retreads and Michelin Airstop tubes.
Incidentally - kudos to Desser - they include a
small baggy of talc powder with the tubes for
convenience, nice to see that. No instructions on
how to use it - they expect you to know that already
- but it's nice that they include it.
My OEM nosewheel looks like the day I installed it,
with 205 hours - guess I'm treating it correctly.

Fuel Pump Failure Mode ...Craig Taylor
Our RV8 has IO360M1A and a Tempest Fuel Pump
#L15473. When cleaning up the aircraft yesterday
after a long cross country I found a trail of
gasoline dye behind the fuel pump drain tube. As a
check, I pressurized the fuel system with the boost
pump on the ground and no leakage was seen. Also,
when pressurizing the system with the engine driven
pump by cranking the engine, no discharge from the
fuel pump drain was noted. The pump has accumulated
1400 flight hours since new.
Does anyone know how these pumps fail? Does the
diaphragm slowly crack, or can the final failure be
catastrophic? (I had planned to attend the 75th
anniversary of my Navy Attack squadron in California
this weekend but feel it would be risky to attempt
the 9 hours of flight time over barren countryside.)

DID YOU KNOW about switching
coverage from builders to flight?
During all of your hard work while building your
aircraft, you couldn’t wait to get it up in the air.
When it’s time to fly, make sure you remember to
update your insurance policy. In fact, it may be
beneficial to update the policy prior to being ready
to fly. Did you know there is no coverage under a
builder’s risk policy once the aircraft is moving
under its own power? You can put fuel in the tank
and you can start the engine, but if the plane gets
away from you, there’s no coverage. We want to make
sure you have the right coverage at the right time.
If you’re ready to get a full flight quote or even
if you just started building, give us a call for
quotes. At Gallagher, we have our girls that work
specifically on Vans, but we also have several other
people on our team that can quote just about any
type of aircraft you can come across.

Finished up riveting the outer leading edge. Then
time to pressure test the right fuel tank. The
wife had a bicycle pump, but it seemed to only fit a
1980's Cannondale tire tube,,, so no joy there. But
I found my trusty Mastervac and pumped things up
sufficiently to soap up all the seams and rivets,
and no leaks indicated, Yay! Installed the

RE: Acrylic Thickness and Thermal Properties ...Clive in New Zealand
A couple more complicating factors:
The thickness of acrylic sheet stock as it comes
from the manufacturer can vary slightly across it's
surface. Part of our business is making acrylic
aircraft windows (including RV12 rear windows for
the local builders btw) and for say a typical 3mm
thickness we have seen occasional variations from
about 2.8mm up to 3.2 in the one sheet. Generally
not a problem because many of the windows we make
are relatively small so we can avoid any issues. But
for the bigger canopies who knows, this might be
contributing to the cracking problem.
Something else to consider is that when a canopy is
blown, especially the longer narrow types such as
the RV8, there is a lot of stretch and thinning of
the acrylic happening at the highest point. Starting
off with say 3mm acrylic could easily see it reduced
to around half that thickness in some cases (think
of inflating a balloon). Add in slightly thinner
than spec acrylic to start with and this could go
some way toward explaining why some installations
fair better than others.
I always cringe a little when I think of the
compression forces being applied when rivets are
used to directly secure acrylic. Not disputing that
many get away with it for years on end but it's not
ideal. With bolts many hundreds of psi can easily be
applied when over-torquing nuts and bolts. That's
why good practice is to tighten to a firm fit and
then back off a full turn of the nut. It only has to
be lightly tightened. Also the hole in the acrylic
should be half as big again as the bolt diameter
with each bolt centred in the hole i.e. 4mm bolt -
6mm hole. This is another disadvantage of rivets
because they try to expand to fill the hole as they
Personally I have gone with Sikaflex for my canopy
and screen. Trying to give myself the best shot at a
trouble free installation. Time while of course

Workbench Retract Wheels ...Mike Rettig
I build my (3) work tables with "retractable

when you pick up the table. Later, I took some thin
nylon rope and tied it to little eyes in each block
and then to another eye under the bottom of the
table. The rope was left loose enough so that the
blocks drop into place when you lift the table edge
slightly. However, when you want to "raise the gear"
you simply pull on the rope, lifting the lock blocks
back up. Hence, no need to bend over whatsoever.

Turf wars between new Avionics and F-402C
in the early stages of designing and building a new

part of the F-402 bulkhead behind where I'd like my
430/327 radios to go. F-402C goes right behind the
panel, across the width of the fuselage.
How are others getting around this? Has anyone
modified F-402C? Has anyone ever moved it? Is it
just something that everybody is building around?
It's really limiting me on placement of my radios...

Flight Testing of Repaired Canopy Crack ...Scott Chastain
The San Joaquin Valley winter fog finally broke
on the afternoon of Sunday, January 14. I raced from
Church to the airport and put some preheat on the
engine while I prepped the Dove for her first
flight since the canopy repair. After taking my dog,
Gracie, for a little adventure walk around the
airport, I pushed the plane out of the hangar for
the first time since Christmas Day. It had been 3
weeks since the canopy was removed.
Will helmet (or head) break the canopy?
With my seat a comfortable height for normal
(blue-side up) flying, I find when I do neg g
maneuvers my helmet hits the canopy. I cinch up the
belts but it still happens. I have a slider and was
concerned if I could crack the canopy?
If I am not going to be doing aerobatics, I don’t
wear the helmet and my head doesn’t hit even in
turbulence. The things I have thought of: lower the
seat but that will restrict forward visibility, pad
the helmet, don’t wear a helmet, or don’t worry
A: I have heard of one
occurrence, here in Colorado, where a very seasoned
RV-6 pilot smacked his head during turbulence and
cracked his slider canopy enough that it needed to
be replaced. That being said, I believe the canopy
had flown for many years before this occurred.
Although it's always been hangared, it sees a lot of
flight hours too.
A: Ages ago, I learned
aerobatics in an open-cockpit airplane over the
ocean. The first thing we'd so was roll upside down
and roll back upright. Then we'd tighten our safety
belts as much as possible. We repeated this and if
necessary, we tightened again. Having no canopy and
a cold ocean underneath made this seem important.

Attempting to Wrap the Cowl ...sahrens
Well Bruce I took your advice. After finishing
the oil door I was going to wrap the empennage
fairing but I decided to have a go at the upper
cowling. Moving to a much larger peice of vinyl was
a little more difficult than I had imagined. The
backing material that is removed is fairly thick and
does not want to bend. I was hesistant to remove all
the backing for fear the vinyl would stick to
itself. It did anyway and much like duck tape, it
really sticks. There is a happy place in there
somewhere where just enough backing is removed to
allow applying the vinyl and removing too much.
All that said about 1/3 of the way into this I knew
it was going to get pulled off. The material is
relatively strong, it will stretch and it will
shrink. It will also tear, especially when heated or
over stretched. Long story short I had some small
pock marks of damage that I wasn't satisfied leaving
on the aircraft. Once that decision was made I just
made this a learning project working on technique,
how much heat was too much and how to work compound

Water Bottle Speed Mod
Review of my panel Thread
are a “few” comments, and of course, your mileage may vary:
1. The USB port on the left is so close to the throttle that there
may be interference with the port or the cables;
2. If there is anything dangling from the ignition key, it may hit
the stick when deflected or be a nuisance on your leg;
3. Things that earn their way onto the stick are those that you use
frequently and need promptly, or need to access when both hands are
busy. Boost pump does not qualify. Also, there’s the concept of
flow, that you move your attention around the cockpit in the same
order as they appear on the checklist to make sure that the switches
are all set. Boost pump on the stick probably wouldn’t fit that
4. Similarly, the only reason for having flaps on the stick is if
you need to dump flaps on the rollout. I’ve thought about doing this
on my RV-8;
5. Nice that your stick grip is not left or right handed;
6. I’ve learned to fly my RV-9A with left hand on the stick, and it
no longer has the awkward feeling it did when I started. You’ll have
all of Phase 1 to get used to it, so you might not need the dual
7. Good that you grouped your switches instead of having a long row;
8. I’d put strobe at the end, rather than in the middle;
9. If you ever do go inside cloud, it will be strobes off, pitot
heat on. You might consider putting them next to each other;
10. The parking brake is in an area normally reserved for power
controls, and more specifically, for carburetor heat. I’d move it.
Similarly for cabin heat;
11. No point in putting warning lights on the center stack, put them
in front of the pilot;
12. Having a light for fuel pump on is no longer considered by all
to be good human factors (quiet, dark cockpit concept). The argument
is that it gets you used to seeing a light on;
13. Move the seat warmer switches closer to the pilot.
Hope this helps,
Well, not only am I nuts for polishing my aircraft, I also am
using vinyl as well. So I started with the easiest component I could
find, the oil door. It took about an hour to explore how much the
vinyl would stretch / shrink..it will also tear.
All in all it was fairly easy to work with once I got started.

Split Screen or 2 Portrait displays
(Des) As a new builder, panel
questions are coming up, and I wonder if there are any comments or
suggestions about which setup would have better utility.
The 10" model allows a split screen, so I wonder if anyone is
finding advantages of using two of the 7" Portrait displays? (well,
one could serve as a backup). Looks like you lose a control knob on
the 7" model. And I haven't seen any examples of the 7" screen
allowing a full screen view of traffic, weather or engine
None of the "Show us your panel" images in the forum showed the two
Portrait displays side by side (also not shown in the photo
galleries of Steinair or Aerotronics).
The mission is for long cross countries, not yet IFR ticketed.
I'm a big fan of the portrait displays, probably because thats what
I've flown in my own aircraft for a number of years now. The 7" is
taller than the 10" but the 2 7's don't have quite as much screen
area as the 10". I chose to keep my seperate engine monitor (MVP-50)
so that I don't lose the screen real estate to the eng instruments.
Doing it this way gives me a larger/taller map than I would have on
the 10" display. I also prefer to have both screens in front of me
for redundancy purposes, with the flip of a switch or on screen
button push the MFD is immediate a PFD so it's a total non event if
one of the screens fails with this arrangement. I'll post some
update panel pictures showing the 470 touch screens I now have and a
few other changes I've made (added a 660 which I mainly use as a
full time traffic page or IFR plate). I'm considering (if I ever
have time) to change this to a 3 screen setup but honestly I'm VERY
happy with the current layout.

RE: Thermal Expansion and Canopies ...Chris Pratt RV-8
Hopefully this is not too far off topic, but 5 or
6 years ago, after hearing of a rash of cracked
canopies that occurred in cold weather with the
aircraft parked in the hangar, I decided that when
my RV-8 is parked I would not completely close
the canopy, i.e. I do not latch the canopy when
parked in the hangar.
I figure there's no need to put stress on the canopy
when it is just sitting especially with the rapid
changes in temperature we can experience in Texas.
Perhaps it has helped, I have no way of knowing for
sure, but so far no cracks. If you currently are
latching your canopy when securely parked in a
hangar, consider leaving the canopy just slightly
open. It may make a difference.

I ordered my RV-14 empennage kit
so now it's time to start asking really, really
basic questions. On the very first page of the build
instructions, it says to "dimple the rivet holes on
the aft face of the VS-702 Front Spar and VS-01401
Front Spar Doubler" and then in the associated
Figure 4 it says "dimple flush aft." Does this mean
to dimple toward the aft or dimple toward the front
so the flush side is to the aft? I assume the
latter, but I don't want to act on a bad assumption
on the very first page of the kit.

assured that I will have more basic questions as I
go, and for posterity I will make future builders
even more comfortable asking their basic questions
since they can't possibly be more basic than mine

for the light. I placed the template in the tip and drilled both
holes to #30, marked out the area for removal with a fine sharpie
and used a cutoff wheel to remove a large portion. Then I used a
small bit in a air grinder and cut up to the line being sure not to
remove it. Some 100 grit sand paper was used and I sanded into the
line a little before checking the final fit. It took about 3-4 times
of removing just a little here and there before the light would fit
in the cutout like it says in the instructions. I think they call
out about 1/2" on the inside and 2" on the outside that the light
protrudes from the opening. The instructions don't say anything
about trimming the light but I had to remove a little material at
the flanges that hold the insert nuts so they not hit the tip. (pics
below) All looked great and I went ahead and drilled the two screw
holes to #27. I assembled the screws and washers and springs.... Uh
Oh.... something isn't quite right. It looks like by inserting the
screws that the whole light has moved outward by almost 1/8". What
used to fit perfectly now fits like ****. I checked the template
against the left side light and the holes in the template seem to
line up pretty well. Not sure whats going on but I suspect that I
may have to fill the holes and drill new ones. I'll figure this out
tomorrow but I do want to say that I am looking for perfection here.
I like working with fiberglass and I want a perfect even reveal all
around the light of about 1/16". Heres some random pics of the
process and some of me just taking pics at different angles trying
to figure out what to do.
Well that didn't go as planned...opening pandora's box.
So I pulled everything down to
ready to remove cylinders, then had one of the
engine shop guys come help me pull the cylinders for
my piston upgrade.
#1 and #2 no problem, pulled #3 and there is a
lifter that's chewed up and it would appear that I
have an issue with a cam lobe.
This "inexpensive" horsepower upgrade just changed
On a brighter note, it sure will be easier replacing
the two studs on the impulse coupled side of my case
for my pmag...with the engine off the airplane.
I guess we all get little surprises like this
somewhere in our aircraft ownership tenure...
Well, Poop. That's what I said when he showed me.

Aircraft Tug-or how to salvage an old Murray ...Sam Buchanan
Even though the paved ramp outside my hangar is
nearly level, the RV-6 just seems to be getting more
difficult each year to pull into the hangar.....the
plane must be getting heavier.....
In order to avoid straining high-mileage body parts
I decided to replace the soft tissue tug with
something more substantial. There was a thread on
VAF some time back about how to repurpose various
means of locomotion so they would move an aircraft
into a hangar.
The father of one our VAFers has a yard-full of lawn
mowers that is in a constant state of flux as he
buys, trades, swaps with the community. He loaded an
old, ugly derelict Murray riding mower of 1993
vintage on my truck and I proceeded to resurrect it
as an RV tug. After some minor refreshening of the
engine, tubes in the dry-rotted tires and a complete
tear-down for cleaning and paint after throwing away
everything that didn't look like a tug, I have a rig
that effortlessly pulls the RV-6 up the ramp and
into the hangar. My regular towbar attaches to a
drawbar on the front of the tug and it backs the
RV-6 into place. My back and knees will live to fly
Go/No Go - Spar Caps Trimming
I started on my van’s RV-10
Empennage kit and in the first step of the Vertical
Stabilizer, it calls for trimming the rear spar caps
(Section 6, Page 2 - Step 1). I made the markings,
drew a straight line and trimmed it. When I came
back and read the plans again I realized I didn’t
straighten the bow while I drew the straight line.
Attached is the picture of the rear spar cap clamped
straight. I placed a piece of scrap aluminum with a
straight edge against it to show the issue. Now the
question is, is it acceptable to go forward?

Sunset Flight ...j-red
I found my old gopro knockoff camera in a drawer
this past week and welded up a mount to fit in a
tiedown slot. The video quality is pretty poor, as
this camera doesn't handle low light very well, but
it was fun just the same to get a little different
perspective on the flight. This might just be what
inspires me to buy one of the newer action cams, and
ill have to try some other mounting locations in the
G5 or GRT Mini
I ended up with the G5 and Backup Battery. My
panel is mainly Dynon so I wanted a backup from a
different manufacturer. The G5 has a serial
connection to the GTN650. The Mini would have been
my first choice but it didn't fit in the space I had
after removing the Dynon D6. The Mini is 4.35" wide,
the G5 is 3.42"
I have been very happy with the G5. Garmin did a
nice job with the internal GPS antenna. I thought
for sure I'd need to use an external antenna but the
internal one works great, even at the top of the
center stack in the 10.

A case of tall pilot/short pilot
The lady and I both have separate
partnerships in certified aircraft but are thinking
of selling off and getting our first plane together,
an RV-6. Thankfully, we live in an RV rich area with
an active EAA chapter. We were able to do a fit
check in a local RV-6 to gather more information on
whether this platform will work for us. We came away
with a few A-HA items.
1. I am 6’3. She is 5’4. The a/c we sat in had about
3” of fwd adjustment on the seat to get her closer
but even full forward, she would need the pedals
closer to her feet. We could put an extension on the
pedal, but we’d also be swapping seats regularly.
Anyone dealt with an issue like this? A back cushion
might help but then we would need to ensure the
ability for full aft stick deflection. Perhaps not a
major issue since she is small.
I was told the placement of pedals are one of the
design decisions made by the builder and can vary
between airframes. The builder of this test bird was
tall like me so perhaps this example was ideal for
2. Canopy headroom. We sat in a slider. Does the tip
up provide anymore clearance? My guess is not.

Kinda blue today. Our daughter is back in CA working on her
PhD in 'chembio' as she calls it - visited for 3 weeks over
Christmas (rare). Drove her to Love Field 0500 Sunday morning
for the SWA flight back - maybe Smokey flew her back to Oakland.
The highlights of the break were time with her, of course, but also
watching her learn to drive the zero turn mower in the driveway, and
flying the drone. Took her for an hour RV flight and got a
couple of waves from her in the driveway as I flew over once or
twice. That's her birthday and initials in the N-number.
The first pass over the house lets her know she has about 30 seconds
to get outside before the second. Rockin those wings...
I gave her a kitchen knife set and Texas-shaped cutting board for
During the break she sent me the link
a newly published paper entitled "Activity-based sensing fluorescent
probes for iron in biological systems." She did the
illustration on page one. It'll be free online for 50 days and
then you have to pay to read the paper.
Advertisers and donations here helped pay for the laptop and undergrad
education that went into the skill set needed to produce that illustration. I thought you might
appreciate some of the fruits of your kindness....science that will
hopefully make the world better.

A Steer, A Tandem Bike, Mountain Bikes: What have you hauled in your
I saw another thread recently that
talked about how great a bearhawk is at hauling
things. I don't think many people realize how much
you can get in an RV-10. It's got the largest, most
comfortable rear seats of any piston single I've
been in. That includes a several aircraft noted for
their interior volume including a C-182, Trinidad,
and Piper Lance. The Lance of course had more total
volume, you just had to choose between legroom or
shoulder room as a passenger.
Ultimately, the 10 is so useful, so fast, and still
so much fun to fly I barely miss the 8. Yes, I do
miss aerobatics, and the 8 is a much better
formation platform. That said the 10 is surprisingly
capable of formation at least up to the FFI limits.
I'll start: I've hauled my family of 4 and a week's
camping gear including a huge tent to Oshkosh. I've
carried the (frozen and edible parts) of what was
once a 1200lb steer, our new tandem bike, and two
full size mountain bikes. I'm curious to see what
others have done.
J_Turner Status Report ...RV-7
Today I wanted to get the wingtips in place and
drilled to the wings. I only got the right one
drilled to #40 but it is straight! To start I made
an aileron center jig and clamped the aileron to it.
Then I had to cut some material off the bellcrank
jig to allow it to clear the Garmin AP servo brace.
Once those were in place I adjusted the pushrod
length and tightened it down. Next I clamped the
bell crank jig to the bolt that holds the pushrod so
I could get the wingtip aligned.

300 Hours: Then and now ...Bob Collins
I hit 299.6 hours this morning in
the RV-12iS project. It's been almost a year to the
day since I took delivery of the first kit. In the
first year, there was a lot of waiting around. I
didn't realize how quickly the emp kit went together
so I had 12 weeks to cool my jets before the wings
arrived. I knocked those off in six weeks but by
then the 12iS has been announced so I chose to delay
delivery of the fuselage kit to get the redesign.
I'm continually amazed by how quickly this has gone
together, even with the stuck-in-traffic pace.
I looked up my RV-7A build and was surprised to see
that 300 hours if about a year's work on that
project too. That makes sense. My routine is roughly
the same: About 1-1.5 hours of work after work, and
a few hours each weekend day.
Pondering if thermal expansion can break a canopy

The thermal expansion Ct for steel is approximately
The thermal expansion Ct for acrylic is
approximately 0.000417 in/inR
I'm going to take a lot of liberties with my
assumptions from here on (feel free to shoot me
Lets say we go flying at -5 degF outside. Lets also
say that our cockpit/sun heater is able to bring the
interior of the cockpit up to 32 degF for a deltaT
of 37 degF as we fly around.
The expansion of a material dl = Ct * deltaT * Lo
The steel will expand by: 0.03552 inches between
The acrylic will expand by: 0.1851 inches.

The RV-14's baggage space is large. With that

frame on it side to pass through and then rotate it
back to right side up. Not sure if you'd have to
remove the fork as well. I doubt you'd be able to
get a second bike back there, due to the
manipulation required as described above. Possibly
if you remove the fork/handle bars. Probably one of
those things you'd have to try. Like others have
eluded too, if you plan to transport a mountain bike

Working on Wiring
Back to Basics | January/February 2018
January 3, 2018 0001Z. Issue
So Tuesday morning only one aviator on the field was
enough willing to go up for a flight in the 23*F morning
air via RV-6, and that idiot person was me (note
one hangar door open).
I know, I know…I’m a wuss from TX and people up north take saunas in 23*F
I should have worn long underwear (and where is mine?), I need to stuff
some foam into the NACA ducts to keep the leaking air around the
closed vents from bleeding in, and heated motorcycle gloves that
plug into 12V are seeming more and more attractive. Other than the
14 minutes it took to get my oil to 100*F, it was a pretty nice
flight. The wing sure liked that dense air. Hadn't flown in
five days...felt good to get off the surface for some alumitherapy
slash mental re-calibration.
And I need to tape off some of my oil cooler. We really just don’t get
that much insanely cold air down here.
It's forecast to be above freezing today for the first time in 80 hours,
so we're pumped. That
fountain ice near the airport is gonna melt.
New Years Flights
Very cold here, +9F this morning
and got up to +17F in the afternoon but had good
sunshine and basically no wind. I couldn't stand it
and had to go flying, went goofing off with a buddy
and shot some touch and goes, just burning fuel.
Interestingly, we have quite the strong temperature
inversion parked over west Texas right now, at 5000'
it was 12F outside and at 8000' it was 41F.
Altimeter was the highest I've seen it, at 30.56
this afternoon, by setting to my known private home

Regarding Buldged Control Surfaces
For anyone else interested, there is potential
for this to have a negative impact on handle if it
exists on other control surfaces as well....
A bulged control surface will make it act as if it
were narrower in cord. That will reduce the
aerodynamic feedback... I.E. make the control forces
lighter (possibly to a degree that impacts control
It can also impact static stability. If the
aerodynamic feedback force of the control circuit is
lower than desirable, it has a lower working force
against any friction within the system.
A small bit of turbulence or an occupant bumping the
stick might induce a small movement of the system
that doesn't return to the same position each time
because the system feedback is too low to overcome
the system friction.
BTW, this is also why friction in the pitch circuit
is such a bad thing. Even if the elevators have the
proper shape they won't re-center the same each time
they are displaced if the friction is too high.
A mis-shaped rudder can also have a negative effect
by reducing centering tenancy (once again hinging
friction being a bad thing) and making the airplane
appear to have reduced yaw stability.
Maintenance Tracking Board

hijacked), I was asked by Plummit about my

Thanks to Gary Sobek who helped me fly the RV-6 from
San Diego to NJ. I learnt so much from him on that

jump. Flying along with Vlad for a while, a couple
of years ago has helped me immensely to change from

have is time. I travel for work Sunday Night -
Thursday (Currently to Montreal). I also have a
couple more hobbies other than flying(Motorcycle
Track Days, Rock Climbing, etc) so it is going to be
challenging. Since I'm already flying, this project
is not critical, albeit very significant. It will be
an interesting journey working on it and finishing

New Guy Checks In ...SpeedyMedina
Hi Guys!!! Happy new year!!! I'm
actually working on an RV-9A! Im trying to have it
ready to Sun n Fun, Maria hurricane delay me a lot
but still working on it!!
here some Pictures!
Need More Heat!
Happy New Year Everyone,
Flew the RV6A today in this 16 degree weather. To
call the heat system inadequate is an
understatement. I have a Vetterman exhaust with one
heat muff, no mufflers, coming into the cabin in the
toe area. Is there anything I can go to get some
more heat into the cabin? I'm thinking add another
muff to the other side and wrap them with an exhaust
heat wrap. What is everyone else in cold climates
using for cabin heat?
RV inverted spin no fear
Having done hundreds of inverted
spins in my RV4 since it's in my free style for
competition for the last three years, I can offer
some advice. It takes specific inputs, attitude, and
timing to make an RV spin inverted as other RV
competitors will concur. I received advanced
instruction in an Extra 300 before I tried it.
Here's a video of a botched hammerhead that starts a
tail slide and possible inverted spin at the 1
minute point, but it never gets to the rotation
The error with this hammer head
was dragging the right wing, kicking left rudder too
late which wasn't effective in rotating the nose
Be careful and hope to see y'all in the box this
lower AL (roll tide)

Canopy fairing fiberglass
Can I do the fuel tanks again?
Fiberglass sanding is tough work! When is says don’t
worry if the glass overlaps the forward edge the
work needed to sand it away isn’t mentioned.
The front center is looking pretty good.
On the left side I attached a pic. Getting the
overlap off on the front sacrificed some of piece A.
There is also metal showing on the aft edge. You
can’t see it but there is a bit of a swale
depression between the two.
I was going to lay in another piece of glass cut to
size to cover this metal and lay it over some small
strips in the depression.
On the other side that little corner where the
window meets the aft structure looks a lot better
but a little bit of the tip of the metal at that
corner shows. How critical is that? Should I keep
glassing it until I get a edge of glass to the top
of the metal? Or will the final epoxy and primer
cure my worry?
Getting ready to order some wings! (slow build) ...SeanM RV-10
I just about have the RV10 emp kit
finished up. I'm just waiting on some composite
materials to arrive. In the meantime my mind has now
turned to the wings. I need to get things in order
before I place my order.
Vans Wing kit options-
1. Landing lights- I will probably go with the
sunspot LED landing light kit that vans supplies
2. Aileron trim- Will be doing this. "operates
independently from autopilot". If I want an AP
system does this mean I'll need different servos for
that too? At what point do I need to start thinking
about an AP system?
3. Float fuel sending units- Will be going this
Things I'm starting to look into:
1. Wing and tail position/strobes.
2. Pitot (will probably upgrade to something heated)
3. Stall horn (is this included in the wing kit?)
5. Would like to do a Garmin IFR type setup /w AP,
but I need to research this more. should I be
looking into this now as well?
When is the right time to get some wiring/crimping
tools? Now? Or are they not needed until mid-way
through the wings? (I'll probably splurge on the
steinair master kit).
Is that a good list? Is there anything else that I
should be researching right now?

Unknown Black Box - What is it?
I'm helping a friend who purchased an RV8 that has
no known electrical documentation. The original builder is deceased.
I came across this small black box that has 4 wires and surgical
tubing attached. It has no markings on the visible surfaces. I have
not yet tried to trace the wiring and where the tubing ends up is
If you happen to know what is it let me know.
Thanks in advance.
My landing gear needs some suggestions, quick!
A few weeks ago my left tire went flat on rollout.
I bought new tires and tubes which I installed today. My gear has
been shaky and I thought the new rubber may help. I previously
reviewed the wheel/axel alignment and it looked ok.
Today after the tires were installed I started to check things and
found I could move the left gear by hand back and forth a few
degrees. I looked up and saw the gear/engine mount bolt moving. I
removed the bolt and found this. (yes, JB Weld was involved)

”Good Saturday Morning! It’s over cast and 3 degrees below 0 in
Alton Bay. I checked the ice we have approximately 71/2” to 8” in

They need a minimum of 12” everywhere - runway, taxiway, parking,
access routes, and snow removal & equipment areas - before they can
open. Then also need to be able to keep everything plowed.

Hangar Lighting - The importance of Color Rendering
Hangar Lighting is a common topic discussed
here and a very important one for anyone building an airplane
indoors. There are many factors that go into a quality
lighting design but one often overlooked is Color Rendering. CRI,
Color Rendering Index, is a number from 0-100, 100 being the most
true representation of all colors as viewed with the human eye.
Traditional older lighting sources still commonly found in our
hangars are T12 Fluorescent and Metal Halide. Both of these sources
have very poor Color Rendering, usually 60 CRI or worse. Other newer
sources like T5 or T8 Fluorescent, or LED typically will have better
Here is an example. The top pic is 400W MH, the bottom LED. The MH I
would estimate at 60 CRI or lower as they degrade with age, the LED
is 70 CRI.

Oh boy, I have some CNC controls to bring into the
current decade. Life is good.
What is it? It is a fixed gantry, 4'x4' CNC router,
with three 5hp spindles, made by a company called
Standard Router Inc. that went out of business in
2005. It is all very heavy steel (can you say RIGID)
with a solid 1.5" thick aluminum table setup for
vacuum hold down. After having moved it, I'm
guessing it weighs over 4000#. I have powered it up
in the shop but am already in the process of tearing
down the controls for a major update.
Tail wheel takeoff technique for bumps
I had an unpleasant takeoff from Catalina island.
I am a tail wheel noob and my normal takeoff
technique is to fly the tail early so I can see.
While on the roll at Catalina near rotate speed, I
hit a hump in the runway which launched me in the
air. I got the nose down and accelerated and
continued flying but it was not pleasant (and it was
my Wife’s first trip in the plane).
I am pretty sure that when the wheels hit the hump,
the inertia of the tail kept it where it was with
the nose rising, increasing the AOA inducing a
premature lift off. The question is, what is the
best technique to prevent that.

Physics of Air Pressure in the RV-14 ...Scott
The physics of air pressure is such that just
like water, it will flow primarily to the path of
Pressure Delta (difference) is what makes air flow
from one point to another.
If there is no Delta, there is no movement.
If the RV-14 heat system has both heat valves
unblocked there is one pressure source (the heat
muff circuit) feeding four paths for the air flow
(two waste/spill-off paths and two into the cockpit
Regardless of where you want the heated air to go
(how you set the heat control valves), it will flow
to the path of least resistance. I.E., if the pilot
is trying to get heat on only their side and there
is no block-off installed on the co-pilot side
valve, the flow can choose to go that way and out
through the waste flow path instead.
As designed, there is still a small amount of
interaction between the left and right heater
controls, but it is not a problem..... as long as
they are only sharing one waste flow path.
This is just one of many little design details that
RV-14 builders are benefiting from with the advanced
level of the kit.... and not having to experiment
with and resolve on their own once flying.

My experience running a tank dry
Due to my impatience and
boneheaded fuel expectations I managed to run a tank
dry on a recent long cross country.
I knew the left tank was getting close to being
empty but I thought it would get me another 10-15
minutes along before I switched to the right tank. I
was about 20 minutes from home with rapidly
diminishing daylight at 3500 ft. "The fuel in the
right tank would be enough to get me home with
reserves", was my thinking before the left tank went
I did not think it would happen but suddenly the
engine quit with the prop windmilling at a good
clip. I was pretty quick to switch tanks and after
about 3 long seconds the engine restarted. I don't
remember if I pushed in the mixture and turned on
the boost pump but was very relieved that the power
came back on.
So...do I fly on, confident that the right tank
would carry me through a darkening sky to my
destination? No. I finally made a wise decision and
diverted 9 miles to an airport I knew had SS fuel. I
made it home later than I planned and logged some
night flying and a landing. I would have gotten home
sooner if I had just topped off the tanks before I
left in the first place.
Lesson Learned: After 11 years and 1100 hrs with my
RV9, overconfidence, impatience, and complacency are
real dangers. I'm glad this happened. It needed to
happen and I am a better pilot for it.

Been Working in the Wing ;^) ...J_Turner
Been slow on the build the last couple of days
but, I did make some progress today. If anyone
remembers a few days ago I got the lights in the
left wing wired up and tested. Everything was quiet
as a mouse in the headset. The problem with that
test was that I didn't have the antennas connected.
When cleaning my bench for prepping the wing skin, I
decided to go ahead and connect them to the plane
just to get them out of the way. At the end of the
day last Saturday, I wanted to demonstrate how nice
and quiet it was to my brother. Powered everything
on and had all kind of radio noise when I turned on
any light. The lights were breaking squelch on both
radios (GTN 750 and GTR 20). After messing with it
for a few minutes I just said the heck with it and
went home to think about the problem. I read about
the auto squelch function and wondered if that was
the problem since There have been updates to address
this function. My G3X's have never been updated
since I got them in early '15. Today I downloaded
the latest software from the Garmin site and
proceeded to do the update. Problem 1) The GSU 73
wouldn't update and problem 2) the GTR 20 wouldn't
update. Called Garmin's tech support and got quickly
transferred to a guy that helped me get the GSU 73
to update. Rebooted in config mode and it updated
very quickly. I think I wasn't giving it enough time
to do its thing. Problem 2 took longer, I called
back and we couldn't quite figure out what was
happening, I said I'll just wait and call back after
giving it some more time. More time was not what it
needed. It seems I may have a CAN bus problem. After
calling back, he told me to turn everything off
except the PFD and the GTR 20. It worked. I have
some troubleshooting to do. The good thing is that
my GTR 20 radio is dead quiet now with all of the
lights on just need to figure out why I'm getting
some error on the CAN bus.

Autopilot During IFR Checkride ...Scott Stewart
The question of "how much autopilot to use during
the checkride?" was something that I discussed with
all three of my CFIIs.
The first guy, who is very "old school", said that I
may be asked to demonstrate it, but not to expect to
get to use it for anything other than a basic
demonstration during the checkride. The second guy,
who is also "old school" said that I could expect to
use it when things got real busy in the cockpit, for
example to keep wings level while copying
clearances. The third guy said to go ahead and use
it in all phases of flight, and explain to the DPE
when and why I'm using it. I went with the third

cruise/level flight, but turned it off occasionally

wings/level altitude without the autopilot. I also
used the autopilot as ATC was giving me radar
vectors to the approach. I made sure to disengage
the autopilot before crossing the FAF, although I
did re-engage it after the FAF on two of the
Finally, on the final approach to KRNT, which was a
RNAV/GPS approach, the DPE failed my primary EFIS.
When he did that, I engaged the autopilot and let it
fly the approach while I reconfigured the
secondary/passenger EFIS to show the approach plate.
All told, I probably used the autopilot for about
50% of my checkride.

IFR training in an RV-7? I did it! ...Scott Stewart RV-7
completed my RV-7 in 2009 and have over 1100 hours
on it to date. Living in the Seattle area, there are
a lot of weather issues to deal with. In the past
few years, there have been a few times that I’ve had
to cancel planned trips due to weather. I’ve also
had to turn back from coming over the Cascades due
to getting stuck VFR on top of the clouds. It’s
never fun at the end of a trip to come home and
spend the last hour of the flight looking for a hole
in the clouds to circle down through. It’s not very
So last year I decided it was time to move forward
on my Instrument ticket. My goal was to use my own
plane to train in, so the first hurdle was to put in
an instrument panel that would be legal, and would
be easy to fly on instruments. I wasn’t interested
in the basic six-pack with vacuum gauges and a VOR.
No! I wanted to have something that I would be
is a great place to look at the latest and greatest.
I spent an entire week with one thought running
through my head – IFR Instrument Panel! By the end
of the week, I had decided on my setup and began
planning the new panel. The legacy Dynon EFIS and
EMS would go away. The Garmin transponder and comm
radio are out also.
My new panel has Dynon Skyview 10” Touch and Dynon
Skyview 7” EFIS, Avidyne IFD440 Nav/Com/GPS, PS
Engineering audio panel, Dynon Comm, Dynon (Trig)
Transponder, Dynon autopilot, and meets the 2020
ADSB requirements. I cut the new panel and had a
friend do the graphics and silkscreen work for me.
The old equipment was removed, and new equipment
I spent a few months testing the new equipment,
learning how to use the Avidyne, and looking for any
bugs. I found a couple of minor issues that were
easy to clear up. The worst issue though, was the
Nav radio (IFD 440 Nav). Although the glideslope on
an ILS approach was rock steady, the localizer
needle was very erratic. It took a lot of
troubleshooting to figure this one out, but I
finally narrowed it down to one of the BNC ends on a
short coax from the Nav/GS splitter to the Avidyne
radio. And sure enough, when I examined the BNC
ends, I found one pin had not been fully inserted in
the assembly. Here’s a video of what the localizer
looked like with the bad BNC pin, and a picture of
the bad BNC pin next to a good BNC connector.
With everything working correctly, it was time to
begin IFR training. I wasn’t interested in going to
one of the local schools, renting a G1000 Cessna
172, and spending thousands of dollars to learn a
system that I would never use again. I wanted to
train in my RV-7, so I had to find an instructor who
would be willing to fly with me. Seattle has a great
flying community, and I was able to find several
CFIIs who could do the job. After flying with
several CFIIs, I settled down to three instructors
who would team-teach me.
I was concerned about the ability of the RV-7 as an
Instrument platform. Would it be too twitchy? Too
nimble? There’s a reason why so many people get
their Instrument ticket in a Cessna. It’s just a
good, stable, reliable airplane. I have done a lot
of aerobatics, formation flight, cross country, and
sight-seeing in my RV-7. Now it was time to see if
it could survive in the Instrument training world.
We began training with standard maneuvers – except
the standard maneuvers were done with my foggles on!
And the RV-7 behaved… OK. Not perfect, but not bad!
I had to learn to have a very smooth, light touch on
the stick, and really focus on the gauges. It took a
few hours of maneuvers to get my skills up to par.
Holding altitude, heading, and speed isn’t easy at
first, but eventually I figured it out.
Approaches, holds, and course intercepts turned out
to be extremely easy with the equipment I had
installed. One of my instructors said that flying
with my panel felt like cheating, because the
instrument scan all happens on one instrument, the
auto-pilot can fly straight and level (or a heading
and altitude) while I was trying to plan the next
maneuver. We moved onto the Cross-country flight
relatively quickly, with a flight from Renton (KRNT)
to Hillsboro (KHIO) to Astoria (KAST) to Hoquiem (KHQM)
to Renton (KRNT). Along the way, we did an ILS
approach to full stop, a Localizer to full stop, a
VOR to the missed approach, and an RNAV-GPS/circle
to land. The cross-country was done in about 75% IMC
conditions, and my RV-7 performed wonderfully!
Fast forward a few months, I had racked up a
whopping 41.0 hrs of actual/simulated IMC, and it
was time to take my checkride. Once again, I had to
find a DPE who would be willing to do an Instrument
checkride in an RV-7. Sure enough, I found my
victim. I briefed him on my equipment, the
experimental RV-7, the tailwheel, the panel, etc.
Oddly enough, he still agreed to go along for the
ride! Because of the experimental nature of the
plane, as well as the engine, as well as the panel,
I had to be prepared to answer all questions about
airworthiness! We spent about 45 minutes going over
airframe and engine logs, discussing the work and
logbook entries that I could do as the builder, and
then going over ADs and service bulletins for the
plane, engine, propeller, and equipment. Finally, he
declared that my RV-7 may indeed be airworthy, and
we completed the checkride.
In summary, if you feel like you’ve got a good
handle on flying your RV, if you are very
comfortable with the instrumentation on your panel,
and if you don’t want to go back to a Cessna for
your Instrument ticket, there’s really no reason for
you not to use your RV!

Engine Misfire Help ...Michael Burbidge 9A
I just finished my third condition inspection.
Before the inspection my engine was running great.
On the first flight after the inspection I was about
15 minutes into the flight, at full power, climbing
through about 4000 ft. when I got what I can only
describe as a misfire. I continued to climb to 7000
ft. and got 3 more misfires, on the way up. I then
leveled off, pulled back the power and headed back
to the airport. I did not get another misfire.
In the first 15 minutes of the flight I was cruising
at about 2500 ft. and probably 50% power. I did not
experience a misfire during that portion of the
flight nor on takeoff.
I have basic Van's instrumentation, so I do not have
recorded flight or engine data. I also did not have
the presence of mind to do any diagnostics. I was
focused on gaining some altitude and getting back to
Mag checks on the ground were fine.
Startup and idle were normal.
Here's the basics of my engine:
1 P-Mag, 1 slick mag
TSMOH @1150 hours
Here's what I did during the condition inspection
that could potentially be related:
Replaced auto plugs on the p-mag, gapped
Cleaned aviation plugs on the slick mag, gapped
Removed and checked p-mag, retimed.
Retimed slick mag, it was about 1 1/2 degree off (it
was overhauled last condition inspection. I think
some drift is normal.)
Slightly re-routed plug wires
Ohm check on auto plug wires
Replaced intake pipe gaskets. (two were leaking)
Replaced intake pipe hose and hose clamps.
Cleaned air filter
Cleaned gascolator (no debri found)
Removed oil cooler, repaired baffle cracks, replaced
Rerouted bottom oil cooler line to avoid chaffing
Replaced, rerouted breather tube to avoid new oil
cooler line placement
I'm not sure where to start looking for the problem.
So far I have rechecked p-mag and mag timing.
Replaced the new auto plugs with another set. Looked
for signs of intake leaks (blue stains, I'm not sure
how long it would take so show up) Rerouted plug
wires so that the aviation wires do not cross with
the auto wires. (they were touching in one spot) My
auto plug wires are separated as described in the
Having done this, my inclination is to go for
another flight, staying close to the airport and if
the problem persists, I will do a mag check at
altitude, turn on the boost pump at altitude to see
if the problem goes away.
I would appreciate any other diagnostics suggestions
to help me find the problem.

The End (of the Wing) Is Near
The end is near, both of 2017 and this wing
The ailerons are finished, and I am quite happy with
the results. One aileron trailing edge is dead
straight, the second took a little work to get out a
very minor ripple; I think the ripple was caused by
not riveting the trailing edge together as soon as
the pro-seal was dry and letting the trailing edge
sit unclamped for a few days. No worries should be
I think the secret to building ailerons with no
twist is the leading edge straightness. I spent a
little extra time making sure the bottom skin was
absolutely flat from the stainless steel leading
edge weight to the spar. Since drilling the leading
edge is very difficult due to the super hard
stainless steel, I ended up having some extra
"lightening" holes in the stainless steel bar.
During final assembly, I made sure the leading edge
ribs sat flat on my super flat surface plate
(granite kitchen counter top). Once the leading edge
is riveted to the spar, the aileron becomes
enormously stiff. I am glad I took the extra time to
make this part perfect.

Pitot install critique please!
Hello all, wanted to get opinions
if my Dynon heated pitot install looks good before I
carry on. I wanted to get this done before riveting
the outer lower skins. Wiring isn't done yet but
that's just a matter of installing a connector on
the 3 power wires. I was going to use a molex
connector for that but I don't have one. I do have
molex pins though. Is it OK to use the pins without
the plastic connector part and use heat shrink tube
over each wire to hold the pins and wires together?
I thought I read that on VAF somewhere. It's not
like I'm going to take that connection apart
Is my engine self-destructing?
I love to learn. That's one of the things that
got me into the airplane building thing. It's also
taught me that there's a lot I have yet to learn...
I have a lycoming o-360, 675 hours SNEW, but was
recently rebuilt (by me) in response to a prop
strike. Case professionally cleaned, cam and crank
polished, tappets overhauled, new bearings,
overhauled jugs, new pistons, piston pins, etc. It
now has about 75 hours on it since the rebuild.
These 75 hours have been accrued over the past 9
The engine uses virtually no oil, and has made good
compression (78+/80 at 10 and 50 hours, haven't
checked it since), and runs smooth and strong. Oil
temps are a little low, but fine and pressure is
about 80psi in cruise, 60 at idle.

Help finding torque value for idler gear shaft
Lyc gurus: I am reassembling a
540. I could not find a specific torque value in the
overhaul manual for the 5/16-18 x .87 bolts that
fasten the idler gear shaft flange to the case.
The standard torque value listed in the overhaul
manual for 5/16 bolts is 204 in-lbs. That seems
awfully high for this application.

The Flat That Wasn't
enlarge the carnage
Before all the recent storms and
fog here I took Flash up for some quality
time in the Tropo. After landing I taxied back
up to the hangar, mental gyros all recalibrated, and
felt what I was absolutely certain was my right tire
going flat FAST. Flop. Flop.
Roll. Bump. Clang. Flop.
Uncommanded right turn. Flop. Wheel pant
obviously being destroyed. Mixture cutoff and
on the brakes to ponder my next move.
I sat there in the cockpit for a
minute or so turning off switches, unlatching
harnesses and re-stowing the headset, starting to
mentally plan the next two hours of wheel pant
removal, finding a tube, breaking the seal and all
the other fun of tire love (a.k.a. Crap Sandwich).
I got out and walked around to view the carnage...
There was none.
the offending rat bastard
The reflector on the taxiway in
front of my hangar had broken from its glue on the
concrete on my taxi out, and when I returned
Flash's right main slid it roughly 15' in fits
and starts. Hopping a little, sliding a
little, making grinding noises - grinding down that
reflector like nobody's business. Noises and
vibrations translating through the airframe and into
my headset cups doing the best 'I have a flat'
imitation I've heard or felt.
Take away lesson: Before you
sit in the plane planning your morning's damage
repair....maybe get out first and see if you're
plane really has damage.

Trial fitting the HS 1213 hinge brackets to the F1211 bearings and
they are to tight ...Jeff Wright RV-12
Hi all, I'm at the point where I'm trial fitting
the HS 1213 hinge brackets to the F1211 bearings and
they are to tight. They fit when there are no
washers included but too tight when there are
washers installed. I'm at a loss about what to do
The brackets are square and the stops are not
undersized. Everything seems good according to the
plans but the fit is just a smidge to tight. I'm
guessing that installing the stabilator after the
emp cone is done would be a real pain if this fit is
not "slide right in" tight.
Can I? Yep.
In flight Rotax power loss
First this is kind of long. Background: Rotax 912
ULS over 200 hours. A few hours after annual. On
annual new plugs and the floats replaced on left
carb. One float was heavy. Carbs were balanced
before I found out float was heavy so they now
appear to be a little off balance. Prop pitched a
little coarser than before, testing the denser
winter air with static around 5000 on ground and
about 5100 in climb out. Flown about 5 hours in the
latest configuration. Climb solo at around 1400 fpm
After take off climbed to 3000' and ran a few
minutes at 5500 rpm at 124 KTS TAS. Slowed to 5350
for cruise and shortly after stabilized rpm suddenly
dropped to 4700 and felt a little rough. Full
throttle application caused no power increase.
Reducing power the engine was much rougher. I turned
around and limped along back home until the Dynon
showed well within glide distance. I then stopped
the prop and requested traffic clearance for a dead
stick landing. In retrospect I should have kept the
engine at WOT since it was relatively smooth there
and not reduced power and shut it off until in the
pattern but I was afraid whatever was wrong would be
made worse. With prop stopped and holding 60 knots
until touch down I averaged 600 fpm descent rate. I
now know stopped engine glide performance.
On ground the engine started fine with normal engine
run up. Powering up the engine felt starved and
would not go over 4600 rpm and would shutter and run
rougher the more throttle you added to increase rpm.
Pulled plugs and if anything they looked lean with
slight light gray deposits. Compression felt fine
but I will run a compression check. Gasolator clear,
everything in the green and as before except the in
flight EGT difference.
Downloaded Dynon. It showed all in line up to about
1/2 way in my 5500 rpm run when the right and left
EGT deviated from 712 and 700 to 726 and 793. That
spread continued until I shut down the engine.
Before I lost power fuel flow was 5.1 gph and it
then deviated from 4.4 to 5.1.
I'm thinking a fuel line obstruction after the
totalizer but before carbs so after the compression
check I'll start disconnecting lines and checking
fuel flow. Other idea is an ignition breakdown at
rpm or under load. Hopefully nothing internal.
Before I start another s... storm on 5100 rpm in
climb as I see being heavily discussed, that is at
75 kts climb which is only maintained for a short
time. Cruise climb is well over 5200 rpm with rate
of climb decreasing accordingly. Yes I'm pitched
currently as a trial to exceed 120 kts but not at
sea level or full gross weight but 3000' solo. It
will even gain another knot or two when you run it
up to red line.
Countersunk Too Deep ...Eztroller RV-14
My question is replace the spar (HS 00903-1), or
move on...? What surprised me was how fast the
single flute countersinking cutter grabbed the
material and took off!

Heat Muff Tip
Two things I have learned for better heat muff
1) You want the opening in the baffle to the SCAT
tube to be no larger that 1" diameter. Use tape or a
restriction plate to close it down. You need to give
the air time in the heat muff to pick up heat. More
air flow than that just means more cold air into the
2) Use coiled solid copper wire inside the heat muff
to improve heat transfer. 18g or 14g solid wire
wound into a tight coil about 1/2" diameter so it
looks like a long spring. I use a pencil or a 1/4
socket extension for a mandrel. Take those coils and
wrap them around the exhaust pipe inside the muff so
the air has to flow between the wire loops on its
way to the outlet.

assessment is ... the

Revised Electrical System ...please review
Only odd spec is the mounting requirement, a
0.125"x16x16 aluminum plate for the full 200 amp
rating. Surely the heat sink is needed only for
continuous use at high amps? The heat sink
size is the same for all three from 100A through
200A so I would think there is some wiggle room. If
I decided to go with an SSC I only have room to
mount on a .125 sink slightly larger than the
contactor. I'm thinking with typical buss amps there
should not be heat issues.
Excellent points! I have revised my diagram to
reflect your inputs.

Known items to be worked on:
1- enlarge oil cooler inlet duct- oil temps are
acceptable but need to be better.
2- CHTs - there is TOO much cooling air.
3- start working on empty weight reduction

Monday morning at
52F was an RV beehive. I showed up with the goal of adding a
quart of oil, some air in the tubes and a quick ILS over at KAFW
before getting on the keyboard. Ended up also going over to
DTO for their ILS 18 practice. What I observed instead was the
whole RV spectrum:
1. Rob working on his -8.
2. Monk working on three different RVs
3. Kay getting ready to go practice acro in his 8A.
4. Three of the other usual suspects briefing for a
formation hop...planes on the ramp waiting.
When I came back into the pattern
Kay was on short final, the formation gaggle was joining
up and cruising out to the NW and I had a text on my
phone from Alex D. saying he saw me go missed over at
KAFW (he was standing on the ramp between three F-18s
and two T-38s).
Oh, and Smokey Ray later texted he wants to join up Tues at an appointed
time in the air for a formation fuel run. Agreed!
If you're still building...it's worth it, IMHO.

It looks like it works! The stick is offset 2
inches and the offset clears the front edge of the

still plenty of room for it to clear the bottom of
the IP and in the full forward position it doesn’t
reach the gear tower cross brace. Cut angle is 65
degrees - 2 cuts 2.3 inches apart. That cut off

Control linkages and washers ...Chjris Mitchell RV-4 project
Q: I am trying to install the various
control linkages from the sticks back to the
elevator. There seems to be a shortage of
information on the plans, though I might well be
missing something. Not helped by these odd washer
sizes that are called out in various places.
So, F-635 on drawing 38. The center bearing has two
AN960-416 washers and two 5702-95-30 washers. Nice
clear diagram and I understand that the 5702 95 30
washers capture the bearing if it fails. These funny
washers are 0.25id and .75 od. Fair enough?
Drawing 30. Where F-441, the big pushrod, is
attached to the elevator horns, there is an AN3 bolt
and an AN365-1032 nut, plus enough washers between
the elevator horns to fill the gap.
Drawing 28, F399 and F-440, are connected to the
front stick base, the rear stick base and back to
the bottom of the bell crank. Two of those locations
(F-440 to back of rear stick and F-440 to bottom of
bellcrank.) indicate to use the little 5702-75-60
spacers/washers. Should I use the same little
washers on the other two locations (front stick to
F-439 and F-439 to rear stick)? That would use up
all 8 of the supplied 5702-75-60.
What about he top of the bell crank to the F441 big
push rod? Can't find the details for that at all.
Finally, two possibly dopey questions:
Why do we not use the larger washers in all these
locations as there are still rod end bearings that
could, presumably, fail?
Why do we use nyloc nuts in these locations rather
than AN - (non-A) bolts, castle nuts/split pins?
As ever, many thanks.
A: (Scott Hersha)
Here's the way I like to think of it - If I was a
bearing in a rod end, and if I became separated from
the rod end (either by failed bearing race or some
defect), then what would happen next. If the answer
is that the rod end and whatever it is connected to
could fall outside of the safe operating area where
it is supposed to be in - it could then jam the
control - well then you have to have something to
prevent that from happening. On your large elevator
pushrod that is captured in the elevator bellcrank,
you don't need a large diameter washer because if
the rod end bearing fails it is held in the same
relative position because it can't get outside the
jaws of that bellcrank - as long as the bolt doesn't
break. On your aileron inboard bracket where it
connects to your aileron push pull tube rod end, you
will need to have the large diameter washer on the
bearing side of the approximately 1/2" spacer that's
there. Even though the whole collection of spacers,
and washers is inside of the aileron bracket, a
failure of that rod end could allow the now
liberated bearing to slide laterally a half inch or
more, which would possibly jam the control tube in
the aft spar opening. That large diameter washer
prevents that from happening.
As far as those very small (and difficult to
install) 5702-75-60 washers - I think the only place
I've seen those used is in place where a normal size
washer would contact and drag on the part that the
ball is pressed in to - like the outboard aileron
bracket on some models, or on a rod bearing where
the rod pivots a lot. That small diameter washer
gives a space between the ball and the normal washer
or surface, so it can move freely without
A: (Gil) There is another
interesting twist here for owners of very early -4
and -6 kits.
Vans changed the vendor for the rod ends, and if you
have the Heim rod ends that were supplied in the
very early kits they had a different profile at the
end of the ball portion. I looks sort of like the
tiny Vans washer was actually built into the design.
I believe this explains why some early kits did not
need the tiny washers while later kits did.
Nevertheless, the aileron pushrods should not bind
in any position of the stick. If they do, add the
These two pictures show the difference:

The other end is connected to a Lyc IO360M1B. The
end of the cable is in the vicinity of the low

investigate. There was a touch of moistness in that
area but nothing more than usual, and certainly
nothing obvious that caught my eye. I tightened the
hose clamps and buttoned everything up.
Any thoughts? Am I missing something? I checked the
other two cables - prop and mixture - and they are
completely dry (none of them are in the vicinity of
any moistness anyway).

To give you a clue, there is a Dyke Delta manual in

doesn't cost anything to dream". Well that line has
run into some serious headwinds so now it has
morphed into "it cost a fraction of a combine". It
seems to be working and she is thrilled to see me

comparison to the inlet area. The 2 round inlets
total 33.6 square inches and the exit measures 84.2

question is how much? Is there an inlet/exit area
ratio that we can use as a starting point?

J-Turner Update Status
Today I made a support for the plane to sit on
while getting the wheel pants and gear leg fairings
Used a chair and some spacers at the rear and an
engine hoist to support the plane from the engine
mount to take measurements for the support. Made saw
horse style support 30.5" tall. This places the
wheels about 1/8" above the ground.
Then placed a centerline to take measurements from.
More pics tomorrow. On the right side I had to
enlarge the opening for the wheel to allow the wheel
pant to turn enough to be somewhat in line with the
centerline of the plane. Also tied the rear of the
plane down to my mini tug with ratcheting straps
because the engine hoist "leaks"down a little in a
10 minute span so, it's not up to the task of
supporting the front all by itself.
Wasted a lot of time rereading the instructions
trying to get the best alignment of the wheel pant.
Not much success today but tomorrow I might have
this thing right......
Another Stuck Valve
A year ago I had a sticky valve on #2. I was
going to do a precautionary check on all the
cylinders as soon as the weather turned bad for a
few days. Sunday was perfect weather in NE Ohio so I
planned a breakfast run of about an hour over some
rough terrain to W Va. My buddy canceled so I stayed
close to home. After 30 minutes of local flying #4
cyl went dead and I was able to land at a nearby
airport. Borscope revealed a perfect impression of
the exhaust valve in the top of the piston so I
pulled the cyl and the valve is very stuck along
with bent pushrod and tube. The piston feels ok but
I am having a qualified shop inspect everything. My
understanding is that this problem is often caused
be a poor hydraulic actuator so that will need to be
inspected also. 40 Year’s of flying Lycoming Engines
and never had a cyl removed.
Rotax Drip Tray
If the carb mount is removed from the manifold so
that it can be inspected, a raised area around the
flow path hole can be seen. It is basically a molded
in O-ring that will seal on the aft side of the drip
tray (if installed).
There is an o-ring in a groove on the intake
manifold that seals the fwd side of the drip tray.
If no drip tray gets installed, the manifold o-ring
compresses on the flange of the carb. mount
producing a double seal.
In the case were the o-ring was incorrectly
installed, the builder moved the o-ring from the
grove in the manifold and attempted to put it in the
very small grove that surrounds the integral seal of
the carb. flange. It does not fit... so it squirted
out during installation.
The statement "this should be used when the air box
drip pan isn't used" actually is indicating that a
drip tray is required. The airbox they are talking
about is this.
It is produced and sold by Rotax and is very
expensive. It attaches to the back of both carbs and
does away with the need for a drip tray because it
is a closed plenum that has nipples for connectiong
the carb vent tubes to. Note that it does still have
a heat shield for each exhaust pipe that has a place
for drain hoses which to me are pointless because
any fuel that ever drains from the carb will go into
the airbox. So what they are saying is if you are
not using the airbox, you should use the drip tray.
Help with slight loss of engine power/running rich
I have an RV-6, O-360, 850 hours, built it 2000.
On take off and climb out the other day it felt a
bit low on power. As I was climbing I started
leaning it a little and the power came up. It felt
like I was at a high altitude airport or like the
carb heat was on. It has not normally required
leaning like this before. I am basically as seal
level and 70-80 degrees. Something seems to have
changed. I checked to make sure the carb heat door
is fully closed and it is. I checked the idle
mixture (which understand does not really effect
full throttle) and I got a 20-30 rpm rise right
before shutoff idling at 1000 rpm.
This is the original carb and I have not touched it
since I purchased the plane. Been running fine. Is
it time for a carb overhaul? Could the float be
causing a problem. I know very little about the
internals of the carb but I can always learn.
Any suggestions on where to start troubleshooting?

Gear Shimmy Video Update ...Rusty
anyone playing along, I ended up replacing the tires
and tubes. I got a cheap balancer, and found that
the left tire was significantly out of round, and
would have required 2.5 oz of weight to balance. The
right tire was fairly round, but still would have
needed about 1.25 oz of weight.
The new 6 ply rated Desser Monster retreads with
Airstop tubes are nice and round, and spot on
balance. I literally couldn't identify a heavy spot
on either tire/wheel combo. I had to open up the
wheel pants a bit more to fit the monster tread, but
it's back together now.
I decided to remove the left stiffener too, even
though it wasn't loose like the right one was. I
figure I'll have them both be the same when I
install new stiffeners. For today's test, I had the
wheel pants on, but no gear leg fairings or
stiffeners. I'm going to leave the tires at 30 psi
since the goal is to fix the problem with the
I didn't note the groundspeed for the original test
in the video, but it was way faster than I hit
shimmy today. Today, I could feel them starting
around 7-8 kts, and by 10-12kts they were both going
wild. The good news is that this is exactly what I
would have expected, so it seems predictable. The
tires are heavier, so I effectively added weight to
the end of the "spring", and also made the spring
less stiff. Both of those changes would reduce the
resonant frequency, and that's just what happened.
Next step will be to install stiffeners as close to
Van's drawings as possible. They allow for mounting
these in front or rear of the gear leg, and I'm
going to mount them on the front side since that's
less in the way of my brake lines. With cold weather

RV-9 travel distance non-stop
Yesterday I flew non-stop from 82IS Landings
Condominium Airpark (northwest of Chicago) to KPIM
Callaway Gardens (northeast of Columbus Georgia).
Total distance was approx 585 miles and took a
little over 3 hours, and burned only 28 gallons of
fuel. Had slight headwind half way and slight
crosswind over Georgia. Never got a good tailwind
but that was ok cause the air was SMOOTH. Hung out
at 9500ft all the way.
Thanks again to Vans for an efficient time machine!

HDX panel upgrade ...Michael Kallenback
Recently had Saint Aviation replace a 6 pack with 10" HDX,
install new G5, XM radio and upgraded 430W to 650. He did an
outstanding job. The combination is a great IFR/VFR platform. It
works well with Vision 385 AP. They guys did an excellent job with
the wiring and the install. Truely a profession install. I would
highly recommend both the product and Saint Aviation to anyone
thinking of an upgrade.
RV-9A Themed Funeral ...Scott Millhouse post
My 9A was sold a few years ago when I switched to LSA. It passed
hands a couple of times with James Swilley being the last owner. I
contacted the latest owner to chat and found out he passed away. His
family raved about how he loved the plane and made it a big part of
his last year. They also gave me permission to post pictures of his
aviation themed funeral. A sign shop wrapped the casket to match my
color scheme and they had a fly over with a missing man. First
picture of the flying plane was when it was mine from the Petit Jean
event 2013. As they said "Life is Good" especially with a RV. Also
notice that the picture shows him as "Gone Flying". A great tribute!
Help me troubleshoot rough running
Ok, bear with me, this may be a long post..
2 flights ago, during a cold start (on a chilly day) the plane fired
right up and then quickly **** back down. This is abnormal for our
6. Normally always fires right up. Anyway, fired it right back up,
started fine, searched for idle for a bit but stayed running.. Good
runup, no issues. Went flying.
Today, the same deal. Fired up, shut back down, fired back up and
zero issues. Good runup, went flying. No issues.
Fly for about 30 minutes. Land. Plane sits for about 45 minutes,
crawl back in, fire it up (starts fine), decently short taxi out,
normal run up and depart.
While climbing out, above ~2250 rpm the engine starts running
rougher than I like, pull the power back to around 2100rpm and all
is fine. Turn downwind and land.
Taxi in and do a quick runup. Oil temps climb a littler higher than
normal, about 240*ish, and the plane runs s rough at 2200 rpm and
Taxi in, pull the cowl, look it over. Everything looks normal, but
there was a funny smell. Semi-electrical. Semi-heater on for the
first time in winter. Semi-burnt electric motor type smell. Not a
Let it rest, call our mech and he suggests mixture setting as the
first place to start looking. Mixture was slightly off. We set it
for about a 50rpm rise when killed from idle.
Do a couple quick run ups to about 2250rpm static and then idle shut
offs messing with the mixture.
Taxi’d back out for a runup just to see how it’s acting. Run up is
good until a few seonds into high power and it begins running rough
again. Rpms drop to 2000-2100ish. Back to the hangar. Smell is kinda
there, but nothing like the first time.
Call A&P and he suggests maybe it’s fouled plugs and to attempt to
burn it off.
Taxi out, attempt to burn off plugs with high power/leaning on the
ground and am unable to get steady enough running to really
accomplish anything. EGT’s got to around 1250. No improvement.
Pull the power back and just for grins, I checked the mags. Nothing.
No drop on either mag. Ah ha! I think. Found it.
Taxi back to the hangar and before shutting down, power back to
~1800rpm and check mags. Got about a 75rpm drop on both. Decent

inspection looks fine. When I jack up one side, the main wheel
just doesn't seem to roll as freely as it used to. I've never
experienced this issue before. Any thoughts?
the calipers and make sure the pins are clean and corrosion free. I
put a light coat of lubricant on them. if the pins get gunked up,
the calipers cannot float like they should.
A: Amen to what
Additionally, take some 150 grit sandpaper, roll it up where it will
go inside the pin holes and lightly hone the holes. Then do the same
on the pins. LPS 3 on the pins and reassemble.

Headset/Mic Jack Wiring ...Pete Miller RV-7
I have stereo headset jacks and mic jacks from
Spruce. I got 3-conductor shielded wire from Stein,
per their recommendation.
My question is how to wire them. I've seen some
video online where the shield is grounded. Stein
documents say not to connect the ground. The Stein
video is pretty straightforward, but again, there's
no mention of doing anything with the shield.
Grounding it makes more sense to me, but I don't
want to redo this later.
I don't have anything else for the panel yet. Does
this wiring depend on what will be in the panel, or
is it standard?
Are you thinking of selling your aircraft? ...Gallagher Aviation
We wanted to remind you that most insurance
companies will short rate you when you cancel a
policy, but sometimes we can work around this. If
you are thinking of selling your aircraft, ask the
buyer to contact us for a quote. If we are able to
write the buyer with the same company that you
currently have, we have a much better chance of
talking the insurance company into prorating your
cancellation. It’s a win-win for everyone! You will
get more of your remaining premium back, the
insurance company gets to keep the business and the
buyer will be working with a Vans specialist who
will find the best options available to them. Even
if we are unable to write the buyer with your
current company, you are doing them a favor by
introducing them to an insurance broker that prides
ourselves on having close relationships with our
underwriters to make sure your policy is the best to
fit your needs. We also have an in-house claims
advisor to work for you, and we were just mentioned
as the World’s Most Ethical Company for the sixth
year in a row. Remember, our business is built on
referrals. The biggest compliment you can give our
agency is to pass on our name.

Gear Shimmy Reduction Testing Plans ...Rusty
For further entertainment, I decided that I'll try
to keep this thread updated as my testing
progresses. It may take a while since the hanger is
a looooooong way away, and it's winter.
The last time I was at the airport, I removed the
fairings to see what sort of stiffeners exist.
They're not exactly as specified, but at least they
were in the ballpark. The most obvious problem is
that one of them had come loose from the gear leg,
and since the leg is tapered, it slides down, and
becomes even more loose. I'll give you one guess
which one that was
I cut the loose stiffener off, and besides coming
loose, it was also coming apart, and the ends were
somewhat water rotted. The other one appears to be
pretty solid, though there is some hollow sound as I
tap on the upper end. Since I could never stand to
have the two not match, and since I figure that one
has some water rot as well, I'm going to remove it
on my next trip, and plan to replace them both.
I also brought the fairly well worn Condor tires
home, and have a motorcycle wheel balancer on order.
If the tires appear round, I will balance them as
best I can, and then reinstall them. If they are not
round, I'll order new tires. The Desser monster
retreads seem to be well recommended.
The first step in my experiment will be to install
known round and balanced wheels, but no stiffeners,
fairings, or wheel pants for the next flight. I'll
try to determine if there is shimmy, and if it's at
a higher or lower speed. Sadly, I didn't note the
GPS ground speed when it happened before, but I have
a pretty good feel for it.
Following that test, I'll install the wheel pants
for another test, then stiffeners, and finally
fairings. I really don't think the gear leg fairings
will have much effect, so I'll probably try to get
it shimmy free before installing those.

Sub in a cherry for standard rivet?
Hey Guys and Gals,
I am new to building and have a quick question about
subbing in a cherry rivet for an standard flush. If
this topic has already been in a post let me know
and I will have this one removed.
I am about to prime and rivet my HS and a useful
trick has been mentioned and I would like to know
its validity. Is it common practice to substitute a
standard flush rivet for a pulled rivet in these
tight spaces where a standard slim bucking bar even
has a hard time getting to? I have seen/heard of a
few tricks for these locations, but feel a pulled
rivet will have the least likelihood of me causing
damage. I understand there will be a small amount of
filler/sanding required to clean up the head of the
pulled rivet to keep my skin looking smooth. I
inserted a few pictures of where it might come in
handy. Like I said, I am only priming my HS and have
not yet even looked too far ahead. Just circled a
few parts on the plans that look a tad...snug.
RV-12 SB 16-05-23 PIREP ...Peterk

I flew from North Texas to Norman Oklahoma yesterday
and back. After returning I found a crack exactly
where the lower circle is on SB 16-05-23. It was NOT
there when I left Norman. I have always used
virtually full-stall landing techniques and never on
I was debating if it was a function of poor landing
technique, hours or just poor design. Still don't
know for sure of course but my greatest fear was
ripping off my prop so I was anal about checking it.
That part worked out.
Keep on eye on yours.
Ok, I’m not sure why I feel like I’m struggling
with the Front Spar on my Empennage, but here it is.
I countersunk HS-710 and HS-714. I think I may have
gone a little too deep in an attempt to make the
dimples on HS-702 fit into the countersunk hole. I
know section 5 says 7 clicks past flush is the
proper depth, however it didn’t seem like the dimple
fit properly. Attached is a link to a picture with a
AN426AD4 rivet inserted into the hole for reference.
I’m worried I’ll need to order new reinforcement
angles. What are your thoughts?
Is My Engine Broken In? ...Rich/Cindy Macrofic
Background: Just completed RV-7A. IO-360 engine
new. Started with 7 qts of oil, with the assumption
that the better part of 1 qt would go to the oil
filter. At 2.0 (tach)/3.5 (hobbs) hrs, I added a
quart of oil. Probably could have waited another 2-3
hrs, as not quite a quart had been consumed. I now
have 13.8 (tach)/16.8 (hobbs) hrs and am not needing
to add additional oil yet. Maybe another couple of
hours? So, in summary, I have 11.8 (tach)/13.3 (hobbs)
hrs on this last quart of oil.
CHTs are behaving, but I did not unfortunately
record the very initial CHTs at a particular power
setting for a current comparison. As a result, I
don't know if I have experienced the 50 degree drop
in CHTs that I have heard about (as another
indication that the engine has broken in).
In trying to summarize the various VAF posts on oil
consumption, it seems to be the general opinion that
10 hrs per qt is a pretty decent consumption.
Obviously, some are getting less and some more than
that. So, I am definitely above that. I have read
Lycomings documentation, but they only specify the
max allowable oil consumption, not a desirable
range. They also only specify a maximum schedule for
mineral oil (25 and 50 hrs), with a stipulation that
the key criteria is stabilized oil consumption.
So, the questions I am pondering. With so few hours,
could the engine already be broken in? The oil has
gotten much darker the last couple of flights, so I
would like to change it. Should I again use mineral
oil or go to standard oil?
Anybody have any other
perspectives/thoughts/experiences that I should
contemplate as I make these decisions? Any thoughts

plugging things together. I'm nowhere near done but
even with this simple picture you can see the
potential for this. The images on the avionics are
just screen shots I took and placed on the screens

Reflections on the Build ...Jpm757
Thirty years ago I got the BUG. Past all of the
flashy Lancair and Glasair ads in Sport Aviation,
there was a small black and white ad for Van`s
Aircraft, "Total Performance" it stated. If true, it
was exactly what I was looking for, so I decided to
pay a visit to North Plains, OR, and the modest
facility of Vans Aircraft. I met Van and was shown
the RV3, 4 and brand new RV6 prototypes. The weather
was lousy so I didn't get to fly that day, but I
sure liked what I saw and plunked down a deposit for
an early RV6 kit. 2 years and $29,000 later I was
the proud owner of one of the first flying RV6`s.
Boy was that a great airplane, and I enjoyed it for
15 years. When I reluctantly sold it. I sure hoped
I'd get another.
Fast Forward to 2016 when a friend had an RV7 QB kit
that had to go. Just like that I was back into
homebuilding! My son had been bugging me for years
to get another RV, so he was totally on board. It is
amazing how much has changed in 30 years, QB kits,
pre-punched everything, and aftermarket vendors by
the dozens. Of course there was also the internet
with its wealth of information. All of this combined
with the incredible community of RV builders made
the new build a pleasure. Still a lot of work and a
lot more expensive these days, but 14 mos. later we
had another flying RV. What a great success story
Van's has become, but yet I still feel they are
still the same mom & pop operation they were 30
years ago - and that's a good thing.

This isn't RV-related, but I thought some might be interested.
My wife's car threw a Check Engine light Saturday, and since it's a
10-year old car I'm thinking O2 sensor. A friend at the
airport suggested looking into the Bluetooth OBD-II scan devices
that plug into the OBD-II port, so I did. A few reviews later
I ordered a $99 BlueDriver from here and downloaded the free app. Hardware arrived Monday
night...problem fixed Tuesday morning (it wasn't the O2 sensor).
Reset the codes via the app. It has already paid for itself,
and it goes w/o saying that my friends at the airport are going to
want to borrow this when their cars throw error codes ;^).
If you like looking at graphed engine data from your RV, you might like
this for your cars (if they were built after 1996 - when the
standard was made mandatory for all US-build vehicles).

RV-12 Documentary? ...Paul Straub video (1hr 5min)
Don't know what else to call it....I never did a 'blog' but now
that my build is over, I wanted to document the story somehow. When
I was considering building an RV-12 a couple years ago, I watched
Dave Gamble's "Building a Van's RV-12" on YouTube and that is what
pushed me over the edge (in a good way) to build the plane. I'm
hoping this might help someone that is just thinking about building
or on the fence. If you ever can't sleep and are willing to give up
an hour of your life that you can never get back, it may or may not
be interesting, but this is the story of my build.
Sunset over MN ...Alex Peterson
This was simply too amazing not to share, taken tonight over
Vadnais Heights, a NE suburb of the Twin Cities. The view is towards
the SW, with Vadnais Lake just touching the wing, and Lakes Wabasso
and Owasso a bit further in the distance. This view lasted only a
minute or two. This was one of the best I've viewed in the 16 years
this plane has been flying!
Water leak from underside
My 6A is pretty tight up top, even with a tip-up. I posted
previously about a 3 piece fiberglass tray which prevents any
leakage from the front canopy seal from making its way into the
instruments, although the canopy seal rarely lets any water in.
Flying some practice IMC approaches the other day in heavy clouds
with 700' ceilings resulted in water dripping out of the drain holes
in the bottom of the fuselage, specifically the forward most drain
hole which is centerline, just aft of the seat back bulkhead. I'd
say that approximately a pint of water leaked out after I parked the
plane in the hanger, following about 1.5 hours in the clouds (no
rain just lots of moist humid clouds).
I found this extremely disturbing and set right away to identifying
the source of the leak, while everything was still wet and I could
hope to track it. Off came the seat backs, floor panels and the
baggage bulkhead panels. I figured it must be coming from the wing
area, even though I had sealed the outer floor ribs to the skins at
construction which had been recommended. I found that virtually the
only evidence of water was along the center of the aircraft, between
the two ribs which create the tunnel for the elevator pushrod. The
drain hole is in the baggage compartment portion, but there was also
water in the portion of the tunnel forward of the compartment in the
seat area and even the aft part of the insulation in the center
tunnel of the floor area was very wet. No evidence of it coming from
outboard and working its way to the center. Aft of the baggage
bulkhead was virtually dry, with only a few drops of water visible.

EGT and CHT at WOT
Not sure if this is a problem but its not something I have
experienced yet. At WOT on takeoff, my #2 cylinder egt rapidly
climbs to 1560 deg and the CHT also goes up more than the other
cylinders. After leveling off and setting cruise power, the temps
come down but #2 is always warmer than the other cylinders. I
removed the air dams in front of #1 and #2, checked for induction
leak, borescoped #2 cylinder but do not see anything out of the
ordinary. Fuel flow seems adequate and engine is very smooth
running. Any ideas? The engine is an O320 150HP and has about 15
hours SMOH on an RV6A
Takeoff and climbout WOT.
Self-discharge or parasite drain?
I've had an EarthX ETX680 in my project for many months now.
Usually it is on the Optimate charger they recommended. A few months
back I unplugged the charger to move some things around. I went to
start avionics today and the battery was dead, showing 7v. I charged
and it came back to 13.65v but I'm trying to figure out what could
be causing this.
This happened over maybe 3-4 months unplugged. The battery is in the
plane and everything is wired up but the master is off. There should

Milestone ...bruceh RV-9A
I have been flying my RV-9A now for 500 hours. We hit it
coming back home from a nice long
Veteran's Day weekend trip to Texas and Big Bend National Park.
I realize 500 is just an arbitrary number, but it got me thinking,
what sort of maintenance items should be looked at more critically
as I hit the first quarter of my engines TBO. Is there anything you
would focus on to inspect or replace just based on engine hours?
Tires and brakes are recent. I do oil changes every 35-40 hours. The
plane has been flying for under 4 years (around 140 hours per year).
My annual condition inspections have been uneventful. I've got P-mags
and the automotive spark plugs get replaced each year. At some point
I know things like seals, hoses, spark plug wires, control cables,
etc. will need to be replaced.

Why the Big Hole?
Q: Drilling the hole in the tailcone
aft bottom skin for the tiedown. Instructions say drill it to 11/16.
I got to 1/2" and it already seems too big. I'm going on the
assumption that just the eye bolt has to pass through. Why
would they want it bigger?
A: And best practice for installing
the anchor is to thread a 3/8" nut on it all the way and then
install the anchor.
The nut allows for adjusting the alignment of the anchor and it
extends it a little lower to help assure that the anchor will be the
first thing to touch in a tail strike.
The bigger hole allows for the nut.

Vinyl Wrap Weight ...Bevan
I weighed a square foot of vinyl (3m-1080) and multiplied that by
my calculated surface area of the entire airframe. The calculated
result was 17lb. I rounded that up to 20 to account for some overlap
and estimating errors.
A local pro aircraft painter and I had a "why vinyl" versus paint
discussion and weight came up. He confessed that an RV he recently
painted in three colours base/clear system probably left 55lb of
material on the airplane.
Even if his estimate was high by double, the vinyl is still lighter.
BTW, I ended up painting most of the fibreglass parts to color match
the vinyl including engine cowl, spinner, wheel pants and wing tips.
Breaking the Mishap Chain: Human Factors Lessons Learned from
Aerospace Accidents and Incidents in Research, Flight Test, and
...free e-book from NASA (updated August 2017). This volume
contains a collection of case studies of mishaps involving
experimental aircraft, aerospace vehicles, and spacecraft in which
human factors played a significant role. In all cases the engineers
involved, the leaders and managers, and the operators (i.e., pilots
and astronauts) were supremely qualified and by all accounts
superior performers. Such accidents and incidents rarely resulted
from a single cause but were the outcome of a chain of events in
which altering at least one element might have prevented disaster.
As such, this work is most certainly not an anthology of blame. It
is offered as a learning tool so that future organizations,
programs, and projects may not be destined to repeat the mistakes of
the past. These lessons were learned at high material and personal
costs and should not be lost to the pages of history.
Status Report ...David Paule RV-3B
Before I could rivet the long belly skin, the side skins need to
go on. The bottom of the belly skin was already riveted to the
various stiffeners and bulkhead flanges, so the only remaining parts
were at the ends and the bulkhead shoulders, and they can wait till
I do the lower longeron and bulkhead riveting for the side skins.
The tape bumps roughly in the middle are folded-over tape, giving me
aen easy place to grab on to for removing the tape. I now like 3M's
model 33 electrical tape. I've tried blue painter's tape, which is
harder to remove, and green painter's tape, which is fine if there's
a wider area to tape but is slightly harder to remove. However the
green painter's tape conforms down into the dimples better.
One of the steps to this gluing is to mask off the areas adjacent to
where the glue goes and then do a dry fit check to verify that the
tape is in the right place. At the upper left, you can see that I
needed to adjust this a bit. The tape is slightly apart from the
joint so that I can form the glue squeeze-out into a fillet there.
Refurb Status ...BruceMe
The canopy on there now is 100% sikaflex built ~2006 (about 2 yrs
before first flight). I honestly did a messy job. Others have posted
better work. My canopy has never cracked or de-bonded to the frame
despite really awful abuse. The "non-critical" skirt which I
sikaflex'd as well, has de-bonded when the canopy slammed open rev'g
to taxiing in wet muddy grass. I will rivet the skirt to the frame
as well as sika. I will also repeat the Sika with this canopy re-cut
project as I do really like it. I'll likely have to carefully
die-grind (scotchbright wheel) off the old Sika in some spots, but
I'm mostly cutting down the existing glass.
This is what I plan to do to the canopy...
Argument FOR filling empty hole with rivet ...Tdeman
Without knowing the exact circumstance (regarding where the hole
is etc), the one question that can be addressed is:
"So, will driving a rivet do anything to restore part of the lost
strength in this longeron?"
We'll see the greatest effect of this rivet
compression, where it will in fact carry
some compressive loads.
That being said, there is still a benefit of having the rivet in the
hole while the longeron is in tension, as pointed out in the article
shared above by Kurt W (as well as other texts on mechanical
behavior of materials...)
In case anybody didn't read the whole thing
, one part that stood out is...
"Both cold working and
interference fit fasteners set up
residual compressive stress fields in the metal immediately adjacent
to the hole (Fig. 14.26). The applied tension stress during fatigue
loading must then overcome the residual compressive stress field
before the hole becomes loaded in tension. The fatigue improvement
due to cold working in 024-T851 aluminum is shown in Fig. 14.27"
Rear Seat Heat ...DonPro
In my 6, my wife often wears a jacket and wants the heat full on
and I am down to a T-shirt and still warm so I knew the 8A would
need rear heat. Learning from the 6 I have aileron and elevator push
tube boots to seal the tunnel. I had Larry Vetterman make both of my
heat muffs and control boxes with 1.5" outlets which works great and
he did for no extra charge but 2" will work too. The key part is
made on a piece of 1/2 X 3" pine that is actually 1/2 X 2 1/2" from
Lowes which I routed two corners off of. I rapped it with packing
tape and put PVA release agent on it but it was still a bear to get
the wood out when done. I had to drill it some. The inlet is
leftover 1.5 push tube from the kit. At full deflection there is
still 1/8" clearance and a plethora of hot air is coming up between
the backseater's legs. Full disclosure, I am preheating my heat muff
air with the oil cooler to save on cooling losses in the summer but
you may not have to. My heat is very hot though!

Air to Ground Freq.
I took my RV-10 up on its first flight this past Saturday, and I
was talking to my father on the ground with a handheld tuned to
123.45. Mostly I was keeping him informed as to what I was doing and
how the plane was behaving, but 10 minutes in someone broke in with
a curt 'Get off this frequency!'
It's my understanding that 123.45 (known as 'fingers' apparently) is
reserved for air-to-air and civilian flight testing, so I'm not sure
who I was intruding on or if that person had any business telling me
what he did.
What's the proper frequency I should be using to communicate with my
ground crew while flight testing?
Trailing edge rivets
My instructions said straight trailing edges was one of the most
difficult parts of building a flying surface. With that in mind, and
being far from accomplished with the rivet gun, I decided to find a
way to get good reliable results with a dead straight trailing edge.
I'm accustomed to building race cars in jigs and fixtures so Van's
"in the air" method is all new to me, and a little scary. Point is,
I'm blessed with tools and equipment most of you do not have and do
not want to buy. One of them is a six foot by six-foot by .625 steel
blanchard ground surface plate flat and square to .010. With this
one can usually get a true result.

So, as I think about my new RV-6, I could imagine a flat tire could
easily lead to a ground loop on landing.

Structural Benefit to Filling Hole With Rivet?
a dumb question, but I wouldn't want to disappoint my friends.
I have a 1/8" hole in a longeron that I no longer need due to
change of plans. It would certainly look better if it had a rivet in
it, but with the curvature of the rear fuselage skin this is not an
easy slam dunk operation. Its not in one of those places where it
will stick out like a big "DOH!" sign. At the same time, I don't
like anything weakening the structural integrity and especially if
its not doing anything beneficial.
So, will driving a rivet do anything to restore part of the lost
strength in this longeron?
Running wires RV8
A: According to the document linked below, installing
a driven rivet produces a local area of residual compressive
stress in the material surrounding the rivet, resulting in
improved fatigue life for certain loading conditions. See
section 14.11, pages 18-19:
As with everything, a bunch of caveats apply. Care must be taken
to also consider the, adjacent structure, maintaining proper
fastener spacing to adjacent holes, etc. Whether or not fatigue
life is a concern given the part properties and loads is another
A: On a fighter jet, or an airliner, there is
much effort spent at making every bit of structure as light as
possible. Skins are chem milled to thin them in areas where they
are not loaded. spar caps are tapered etc etc etc. On an RV the
longeron is the same size and cross section throughout its
entire length. It probably only has to be that size for a very
small portion of its length. In fact, when he was designing it,
Van might have sized the angle and then used the next size up,
because you can't buy a 37/64" angle that is 7/64" thick (I
invented those numbers). The extra material is left in, because
who is going to bother trying to get it perfectly optimized.
If you want to do a major stress analysis at each hole, go
ahead. It's your airplane. And drilling a hole does reduce the
cross section and therefore makes it weaker in tension by
definition. But this is only a problem if that part is optimized
to be exactly as strong as it has to be. The longeron will be in
tension at full rudder 1 way, and compression with full rudder
the other way. Same with pitch up vs pitch down. So if you
increase the compressive strength for left sideslips, but you
don't address the reduction in tensile stress in the other
direction, you have not made the structure any safer.
I would only really worry about holes in the longerons up near
the steel gussets that tie them to the firewall. That would be
the area where they are most highly loaded and there are 4 -3
bolt holes in them. An AD4 rivet hole further down is not going
to compromise flight safety.
No, I am not a Vans employee but I have been an Aero Eng for 28
yrs and I do know something about loads and aircraft structures.
And I have a 4 that has some holes in places they shouldn't be

Therefore, we have temporarily suspended
updates to the Flying RVs page on our website. At some point soon,
we will receive the first flight report for the airplane that will
be deemed to be the notional 10,000th RV, and announce the event. We
anticipate that it will be in December sometime, if we continue to

Update on SB 16-12-16 ...Andy Karmy
Just a quick update to this old thread. I had the "pleasure" of
helping a good friend install these 12 bolts this weekend! What fun.
Once he had all of it opened up and removed the center control
column and sticks I was ready to work. Took 5 hours. We were able to
get all 12 in without any holes just using the center access hole.
10 of them went in from the back (inside the spar box) and 2 had to
go in from the front due to interference with the nuts on the rear
spar that hold the seat rib in place.
The only thing that we found to work was to use a camera (I had a
cheap USB camera) and put it on a stick. Then use 12" forceps with a
slight notch ground in about 1/4" from the tip to hold the bolt.
Then with one hand on the camera and one on the bolt you put it in
the hole (Mars rover style)
Boy it feels good to have the last one go in place. And the defeat
you feel when you bump the bolt that's half way in the hole is real
But in the end it's doable if you have the right tools at hand.

ADDRESS TO FELLOW-COUNTRYMEN
The White House, November 11, 1919.
year ago today our enemies laid down their arms in accordance with
an armistice which rendered them impotent to renew hostilities, and
gave to the world an assured opportunity to reconstruct its
shattered order and to work out in peace a new and juster set of
inter national relations. The soldiers and people of the European
Allies had fought and endured for more than four years to uphold the
barrier of civilization against the aggressions of armed force. We
ourselves had been in the conflict something more than a year and a
half. - With splendid forgetfulness of mere personal concerns, we re
modeled our industries, concentrated our financial resources,
increased our agricultural output, and assembled a great army, so
that at the last our power was a decisive factor in the victory. We
were able to bring the vast resources, material and moral, of a
great and free people to the assistance of our associates in Europe
who had suffered and sacrificed without limit in the cause for which
we fought. Out of this victory there arose new possibilities of
political freedom and economic concert. The war showed us the
strength of great nations acting together for high purposes, and the
victory of arms foretells the enduring conquests which can be made
in peace when nations act justly and in furtherance of the common
interests of men. To us in America the reflections of Armistice Day
will be filled with - solemn pride in the heroism of those who died
in the country’s service, and with gratitude for the victory, both
because of the thing from which it has freed us and because of the
opportunity it has given America to show her sympathy with peace and
justice in the councils of nations.

RV-12 Winterization Kit (optional)
RV-12 coolant radiator and oil cooler block-off plates for use in
cold climates when ambient operating temperature is below 50°F
The use of these block-off plates allows the oil temperature and
coolant temperature to be maintained within the normal operating
range during cruise flight and improve cockpit heater performance.
With the RV-12 not having an oil or coolant thermostat, it is not
possible to add winterization parts that will properly regulate oil
and coolant temperatures at all temperature conditions.
The use of this winterization kit will require any pilot flying the
aircraft to actively monitor the engine temperatures and make
adjustments to the installed parts, to coincide with air temperature
changes that are common from one day to another. Example - It is
possible that at warmer temperatures, a particular airplane may
allow for partial blockage of the radiator with the Radiator Cover,
but require that no Oil Cooler Cover be installed.
Steve Smith VFR-->IFR PIREP
Out west here, one likely scenario of VFR into IMC is with fire
smoke. I've made some pretty marginal flights. On one of them, the
vis went from 5 miles and a good horizon to 1 mile and no horizon
fairly quickly. But not instantly like going into a cloud. It gives
you a little bit of decision time, but you better make the right
decision. I had started a descent to maintain good sight of the
ground ( I knew I couldn't get on top of it because I knew how high
it went) so I made the descent much more aggressive, and turned
On another occasion, I was flying east across basin-and-range
country with 4 mile vis, but the periodic ridges crossing in front
of me gave me a good horizon. At a certain point in central Oregon,
the ranges stop and it is just a big basin, which happens to be the
same color as the smoke. Now no horizon. In this case I climbed
until I had a good horizon on top, although I could only barely see
the ground at all.
For me, the key is recognizing the evolution of the conditions and
acting soon enough to prevent a complete loss of horizon or ground
vision. It is a bit different with smoke because it happens
gradually, not suddenly like going into a cloud. But that also makes
it insidious. Its easier to say I will keep going unless it gets
worse, and it keeps getting worse. And of course next time I might
not recognize the trend and make a good decision soon enough.
The "experience" I've gained from these is two-edged. Part of me has
gotten more conservative and more willing to turn back. But part of
me has gotten more confident that I can recognize the situation and
react accordingly. I have to remind myself that this is dangerous
stuff, and this thread is really good.
To Dan's point, although I am not instrument rated, I have done a
lot of hood work, including a BFR two years previous with 1.5 hrs
under the hood with lots of extreme attitude recovery. The rub is
not having appropriate equipment in the airplane.
With the advent of glass cockpits, it is now more common to have a
good artificial horizon. But I really favor old-fashion round
gauges. I don't want a vacuum system. So for now, I have just a
Trutrak ADI-pilot. But it is not a "real" AI. It synthesizes AI
information from rate gyros updated with other sensors. I'd like to
think it would be a good fall-back instrument for inadvertent IMC,
and I have practiced a little with it, but I find that it does not
always know correctly which way is up. (maybe something wrong with
it?) An electric ADI is pretty expensive, but I am pretty seriously
considering the investment. Or perhaps succumb to the glass side and
get a Garmin G5.
AOA Pitot RV-10 Install Pics/Words ...Bill Peyton
I installed the AOA pitot in the Van's specified location with no
issues. I also ran the tubing down the center j channel using a
caterpillar bushing in each penetration. No additional holes needed.
The strobe wires were run separately for EMI separation just in
case. I did not use wire sleeve for the remaining wires, I just ran
the wires and cable tied. I ran a couple of extra wires down to the
end just in case.
Mountain Rotor Diagrams ...Carl N.
I've flown mountain wave in sailplanes, and the wave is usually
very smooth since it is a laminar flow phenomena (requiring a stable
atmosphere) and forms above the convective layer. The rotor is
caused by friction with the ground, and can be extremely turbulent.
If there is enough moisture in the air, the rotor will be visible
with a cloud forming at its top and should be avoided.
When flying wave in a sailplane, you basically stationkeep in the
lift areas of the wave (watching the ground drop away), climbing
past the leading edge of the lenticulars, if they are visible.
Notice that there can be Primary, Secondary, Tertiary, etc., bounces
of the wave, depending on the wind strength, angle to the mountains,
and stability of the atmosphere.

"Van’s Aircraft has always prided itself on customer support. One
aspect of this support is our commitment to continue the ready
supply of parts for older models that have been superseded in design
and ease of assembly. The RV-3, RV-4 and RV-6 were the basis of our
product line for quite some time. In recent years we have seen their
respective kit sales decline significantly. Although kits and spare
parts for these models remain in our inventory, the cost to produce
and warehouse parts that rarely sell is ever more burdensome.
Therefore, to mitigate the costs and logistical difficulties that
arise from low sales, we must adjust our production, pricing and
This is to inform builders of these models that prices for these
kits will significantly increase after January 1, 2018. Production
runs for these kits will not cease, but the period between them will
increase dramatically. We estimate production gaps of one year or
more that can easily translate to delivery dates of one to two years
from date of order.
We at Van’s want you to continue your project to completion and
therefore suggest that you place an order for an empennage, wing,
fuselage or finish kit now at current prices. If we receive enough
orders for these kits beyond current inventory by years end, we will
institute a production run to cover them all. This will yield
reasonable delivery times. Spare parts will also remain available as
supplies last. However, once depleted, parts may still remain
available, but will be produced on a one-off basis. Production of
any one part is expensive so an elevated price compared to a similar
part in another model RV is to be expected.
Kits available for order are:
RV-3 Empennage, Wing, Fuselage and Finish
RV-4 Empennage, Wing, Fuselage and Finish
RV-6(A) Fuselage and Finish
Current prices will remain in effect for all kits ordered prior to
December 31, 2017. Subsequent orders will be subject to the

VFR into IMC ...crabandy's PIREP

So there I was, several years of instrument currency and even
flirting with proficiency every now and again. Weather triple
checked, lots of extra fuel for the IFR flight plan filed with an
alternate and VFR areas duly noted. Uncontrolled departure airport
reporting OVC 1700 double checked visually, I'm sure center is gonna
be busy given the conditions but I don't want to spend an extra
20-30 minutes picking up my clearance via FSS. It's a familiar
airport with no terrain and with 1700 OVC I was more than
comfortable departing VFR.
Normal startup, runup, taxi and takeoff with my course and
frequencies pre-loaded. As I turn on course and switch to center
frequency it appears my 1700 OVC/VIS is obscured with some newly
formed mist and lower clouds so I level off at 500 AGL to stay clear
of clouds. I momentarily thought about returning to land and pick up
my clearance through FSS but press on because it's familiar
I confidently called center requesting my IFR clearance, center was
busy and I eventually received a "sqwuak and maintain VFR" currently
15 miles from my departure airport still at 500 AGL. Because of my
low altitude I can only hear center with the squelch on and seems my
transmits are broken as well, I know the farther I go the worse the
frequency gets at low altitude.
30ish miles (minutes at RV speed) from my departure airport I still
don't have a clearance and even with the squelch on I can barely
catch half of what the controller is saying. Seems a NASA test
flight is non-radar in a low block altitude in my vicinity that also
can't hear center on frequency. Again I contemplate turning around
but my closest airport is 30 miles away. Surely I'll get a clearance
soon, I press on watching my terrain page as a clearance in a couple
minutes is safer than flying back at 500 AGL.
I wasn't shy about my clearance request at this point and eventually
had my IFR clearance relayed through another aircraft after center
finally determined the NASA test flight position, an IFR clearance
never felt so good.
How did I rationalize myself into this situation, as always it was a
chain of events:
-didn't want a FSS delay
-1700 OVC was comfortable for departing VFR and pick up clearance
-squawk code and talking to center feeling I would get a clearance
-I've got a squawk and ATC is expecting me to be on route
-I'm too far away to turn back
-If I could just get my clearance I would be fine
Looking back when I hit the OVC/VIS at 500AGL I should have turned
around and landed. I wouldn't think of departing without an IFR
clearance in 500 OVC yet I rationalized and flew for 30ish miles
because. Judgement isn't taught, it's gained through experience.

Mountain Flying - More Lessons Learned ...pvaslovich
Saturday afternoon passenger drop-off flight over the Southern
Sierra Nevada Mountains from Inyokern (IYK) to Kern Valley (L05) -
less than 30 miles. Wind 260/12 at IYK. Climbed to 8500 in clear
skies to safely clear the two major ridgelines enroute. A little
bumpy, but nothing unusual for the Southern Sierra. Uneventful leg -
except noting winds were on the nose at 42kts at 8500 ft.
Return leg at 7500 ft. Fewer bumps than first leg until lee side of
westernmost ridge. First roller banged my head off the canopy
(thought I was tightly strapped in - but I was wrong) and induced an
uncontrolled right roll. Second roller immediately thereafter
continued roll with nose down pitch. Ended up about 120 degrees
right wing down, 30 degrees nose low, accelerating. + 4.5, -3.1 g's
on the g meter. This occurred within 2-3 seconds under clear skies,
in pretty calm air with no warning.
1. Be wary of ridge crossings with high tailwinds.
2. Ensure you have enough altitude for recovery from nose low
3. Be comfortable with sudden unusual attitude recovery (I'm a
former Navy A-4 Adversary pilot; joke about being more comfortable
upside down than right side up).
4. If you suddenly find yourself nose low with excessive bank, roll
wings level before pulling to the horizon - otherwise you risk
increasing bank into a tight nose down spiral.
5. Be aware of your nose low airspeed - Vne is a real number.
6. Clear skies does not correlate to smooth air in the mountains.
7. Be wary - and prepared.

RV-4 Firewall Wrinkle Update ...from other -4 owner (Vac)
It's fairly common for -4's to suffer wrinkling in the lower
corners, usually as the result of a hard landing load or continuous
operation off of rough surfaces. The aluminum fuselage structure
flexes under load (as it's designed to do), but the hard stainless
firewall suffers stress wrinkles or cracks. As long as there is no
permanent fuselage primary structure or landing gear leg
deformation, the firewall itself is non-structural. If the stainless
has any holes or cracks, they should be smoothed and/or
stop-drilled, as appropriate and filled with high temp silicone to
preserve firewall integrity.
Similar to your situation, I also watched my brand new replacement
lower RV-4 firewall crack in the lower corner within a few landings
because I didn't "pre-stress" the lower firewall thru-bolts...i.e.,
before drilling the replacement firewall rivet holes and riveting,
use a nut, bolt and fender washers to properly compress the
stainless in the corners to mimic the compression imparted by the
engine mount. So that would be my primary suggestion in addition to
adding the RV-8 style gussets as suggested by Van's!
Likely you are already aware, but be sure to check the engine mount
for any cracking as well, since the same stress that induces the
firewall wrinkling causes stress at the welds in the gear leg
sockets. Engine mount fatigue cracking is not uncommon (mine cracked
at about 1100 hours). If your mount is finished in black
powder-coat, visual inspection can be difficult, and may require you
to remove the powder coat in suspect areas to make a determination.
If the engine mount is dark, sometimes the presence of a small
amount of grease at the weld can provide a visual cue that the weld
may be cracked. If the weld cracks, it's possible for some of the
grease to be forced out of the gear socket through the failed weld
as the area flexes during taxi, takeoff or landing. Given the
option, a painted mount that uses dark primer and light finish color
can simplify visual inspection.
RV-10 Top Antenna Reinforcement ...Bill Peyton
Because there is a slight curve where you are mounting it, if you
make a stiffener it will flatten the area above the stiffener and it
will show. Ask me how I know. What I ended up doing is creating a
stiffener that is fastened to each stringer, I then made shims and
installed washers between the aircraft skin and the stiffener so the
shape of the outer skin is unaffected by the stiffener. You will
never notice the slight leaning of the antenna. The antenna is
extremely stiff doing it this way

That was me yesterday in Springfield Missouri And I didn't get on
the gauges for almost 30 seconds. I was at 600 ft AGL under a

doing what every mishap pilot does, looking out the window searching
for the ground. I was lucky and learned from the scare. For 30 years
as an Air Force Aerospace Physiologist I taught pilots to get on the
gauges. I got humbled, it's easier said than done.

Status Report ...David Paule -3B
Today's job was to glue the long belly skin to the fuselage. I'm
using G/Flex epoxy, the thickened variety, which has a 45 minute pot
life. A dry run showed that it took me 1/2 an hour to get the skin
and the hardware all set up, so I knew I needed some assistance.
Dave Dooley stopped by to lend a hand.
The skin and substructure was ready to go, with tape on and the
cleco tips oiled.
I mixed up a couple tubs of the glue and we started buttering it on.
It went to the perimeter and the shoulders of the bulkheads. Then we
lifted the skin into place and with the exoskeleton, started
clecoing it all together. We only needed one cleco every four rivet
holes but we added a few more, here and there, for assurance.
Then we wiped the epoxy off the tips of the clecos and pulled off
some of the tape and made fillets at the edges of the joints. Dave
left and I took this not-so-great photo.

Hurricane Damage Q/A ...Greg B.
Q: In preparation for Harvey I put my nearly completed fuse up on
a table, resting on a piece of old brown carpet. While we did not
get flood water in the garage nevertheless somehow moisture got
between the carpet and underside of the fuse. This I discovered
yesterday(so about 2 months) when taking it down in prep for
prime/paint the interior. The carpet stained 2 approx 1 sq foot
areas along with depositing some glue-like material. I have been
able to remove the material deposits with acetone and lots of elbow
grease and even more cussing. But the aluminum appears to be
permanently stained a lite brown color. It will be painted so I
don’t really care about the cosmetics but am concerned if I have
compromised the integrity of the aluminum. I have put a thick layer
of paste wax over the area to try to limit any further corrosion. I
wish I could post pix and that’s something I’ll learn to do soon but
in the meantime any thoughts are appreciated.
A: If the aluminum
surface is still smooth and shinny and the only visible change is
coloration/staining, I don't think you will have any problems.
Just make sure you get rid of every bit of the wax before painting
or you'll have fisheye problems. It's really hard to clean
contaminants like wax & oil out from around rivet heads when
prepping for paint.

their guidelines spelled out.

Guess Who is Going to OSH Next Week for a Big 'O Award
building an RV-4, Rob drew on his background in electrical
engineering to design and build his own engine monitor. He thought
he’d just make one for himself, but then a friend wanted one, then a
local avionics shop wanted one, and suddenly, Rob had a new
business. Advanced Flight Systems was born, focused on manufacturing
and selling the ACS 2002.
The monitor evolved from the first color screen available to the
experimental market to an EFIS with synthetic vision, attitude, AOA,
mapping, weather, traffic, and integration and connectivity with
other outside components. After joining forces with Dynon Avionics
in 2013, Rob was able to focus on his latest innovation, which is
designing and building complete plug-and-play panels using a central
control module that eliminates most of the wiring involved in
building an airplane.
What started at the dining room table in the late 1990s is now a

MGL V16 transceiver about to be released
The V6 and V10 radios where based on an
original MGL design many years ago that was never put into
production. Subsequently another South African company called South
West electronics took on the original hardware design and packaged
it into the V10 and then V6 formats. MGL itself provided the
firmware. These radios where then sold under the MGL brand name.
This arrangement has come to an end a year ago. The V6 is still
available through MGL Avionics in the USA but is no longer a branded
MGL product. Ownership of the IP has passed to South West
Thus a year ago MGL started the design process of a new radio to be
called the V16 - this time a true MGL product, fully designed and
manufactured in house.
The first production batch of the V16 is now ready to be released.
Here are the bullet points:
1) 10W+ TX power, very high efficiency, low DC power needs.
2) Built in SWR meter for antenna checks and power measurents
3) World's first fully digital airband receiver, easily surpassing
all required certification requirements for any receiver class.
Based on direct conversion I/Q zero IF technology. No spurious
receptions, excellent sensitivity, selectivity and large signal
handling abilities. Very high audio quality, zero distortion.
8.33Khz and 25Khz channel spacing with full support for offset
carrier operations in each.
4) Impulse noise detection and removal (removes typical ignition
noise and many other noise sources from received signal).
5) Recording and simple playback of received transmissions.
6) Two circuit intercom, fully digital 24bits. Newly developed noise
gating combines the best features of a traditional VOX and MGL's
Vogad into a single, simple to use and highly effective system.
7) Independent RX and intercom volume controls.
8) Split module design. Transceiver body can be used stand alone
with any MGL iEFIS G3 or combined with either a 2.14" head or a
3.1/8" head. Both heads are color and the larger one has a touch
screen as well. You can also use multiple heads and connect to EFIS
at the same time.
9) With any of the two heads, the V16 is protocol compatible with
industry standard protocols (selectable in head setup). Note that
NAV/COM protocol compatibility requires the MGL N16 navigation
receiver which should be available by February.
10) Lowest cost of any COM transceiver available, combined with N16
lowest cost of any NAV/COM available.

Another Take on Oil Door Hidden Hinge
Initially, I was using a formed sheet-metal
hidden hinge for my oil door. Similar to a number of products
available from experimental AC suppliers. I didn't really like this
solution. I thought there was too much flex in the hinge system to
work with my push-button camloc latch. I was able to pop the door
open with light outward force since the hinge would flex.
I designed a new hinge that works much better. I am probably not the
first to make it this way, but haven't seen it posted here. It works
very well. The final version incorporates a spring to hold the door
open. Total weight is only slightly more than the Vans setup, most
of that is from the latch.
Note: I made my oil door from aluminum. I had already drilled it for
the formed hidden hinge, that is why there are extra holes. In the
end, I filled those open holes with rivets.
The hinge pivot could also just be a solid
shaft. I machined bushing on my lathe. The bolts are fully torqued,
the bushings have a step machined in to set the end-play. There is
very little play (less than a piano hinge) to allow fretting of the
Normally, on the pink cow at least, the area where I have the hinge
mounted is a low spot between the cowl honeycomb core and the oil
door flange. I filled this area with epoxy/flox for the hinge mount.
Forward Stick Authority on takeoff RV-6
I finished my tailwheel endorsement in a Super Cub two weeks ago.
So now that I have 6.5 hours of TW time, I am obviously an expert.
In the cub, the takeoff procedure was stick full aft for two
seconds, and then take 3-4 second to go full forward on the stick
and hold it there. The tail would raise, but would not raise further
than approximately level flight.
I was surprised that it really was generally not possible to raise
the tail too far and have a prop strike.
My question in the RV-6 is this: if I go full forward on the stick
in the RV-6 and hold, will the tail continue to rise as speed builds
and eventually cause a prop strike?
Or is the design of the RV-6 such that full forward stick on a
normal takeoff (no gusting winds), will not cause a prop strike?
iPad Pro 12.9" in RV-9A Panel ...dannyatc (Brussels)
The ipad can run 2 apps together using its sensors , one is
running Skydemon (a mostly european nav - app) second app is A-efis
which is quite nice
I also made my own ipadholder :I slide it in , including its
cover and it's kept in place by the canopy , had to cut a small hole
since it's the 12,9" ipad
