A Father's Blessing ...Scott Chastain
A blast of rain and cold weather
swept through California at the end of the week, and
I awoke Saturday morning to clear, crisp flying
weather. I drove out to the airport and put some
preheat on the engine while I waited for the old man

My wife and I were flying to a

Not sure who it was for, but I wonder if it worked?
RV-Lancair Bro Day
We finally, FINALLY!, got some
decent flying weather today, so Owen, Darwin and I
saddled up and flew to Gwinnett County [LZU] for
lunch today at the Flying Machine. It was roughly a
45 minute flight from Asheville, and the weather was
clear, and smooth. On the way back, some scattered
clouds had formed at ~6,000' over Toccoa, with
associated light turbulence underneath. It was fun!
Wing skins on!!
Right wing bottom skins on. Both wings skins are
now done. Enlisted the wife for some of the harder
to reach ones. This is one small milestone I've been
looking forward to. It was warm today in the garage.
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
into soft dirt and a little grinding action on the
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.
from old fart Roger.........
I want you all to know that I really appreciate the
numerous “Thank Yous”, compliments and “Atta Boys”
sent my way for running this outfit. However, I
often feel the shoe should be on the other foot.
Today’s event at Punta Gorda (KPGD) is a case in
point. It was way too cold to fly my old Stearman an
hour each way. No problem, Old Fart Jeff Weston
chauffeured me in his 1958 Comanche 180... a truly
great airplane. Once at EAA Hangar 565, Old Fart
Larry McClure and his crew fed me, and even gave me
an “Old Fart” coffee mug. Then Old Fart Walt Fricke
chauffeured me across the field to the hangars where
we were all treated to a tour of incredible
aircraft. The tour was made possible by Old Fart Jim
Lyons. And, more than twenty of you braved the cold
and flew in to let me look at your airplanes.
Makes me wonder who should be thanking who? How
about a big, “Hip, Hip Horray!!!” all the way
What a great venue!!! The EAA clubhouse was once the
concrete backstop for sighting in P-40 Warhawk
machine guns. The airfield was a WWII training base.
It is the only WWII building remaining on the field.
Here’s a pano shot of the interior. I think Larry’s
crew fed well over fifty.

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.)
Any knowledge that you all might be able to provide
will be appreciated.

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.

The things I've done in the last month are small

PnP Data Point ...AndyRV7
I've flown a few dogs in my 7 and none have been
crated. I looked around for a soft sided crate but
they don't seem to be made to fit an RV without
giving up some useable space. And they seem to be
unable to hold a curious dog in place, from the
reviews I've read. Also, the dogs are mostly crated
when they get to you, whether you are the 1st leg or
the last. I always specify I can't use a crate for
If I fly the flight alone, I take out the passenger
seat and put 2 or 3 harbor freight moving blankets
down and create a little bit of a cradle with them.
They are ALWAYS on sale for $5.99 and once folded to
fit the plane space, will contain any potential
"issues" you may have. I have not had an issue
yet... If a friend wants to come with me I put the
blankets in the baggage area. Most dogs have been
energetic and curious once loaded but all have slept
once we started taxiing and the canopy was closed. I
tether to the support behind the seat and keep it
long enough for the dog to lay down, but short
enough to keep them from reaching the controls. You
can add some shade in the Summer.
Like someone else said, it's a great thing if you
like helping animals. I began just taking trips that
had 15 pound sized dogs. My last trip was a VERY
energetic Springer Spaniel of about 25 pounds. I
realized then I could probably handle a 40 pound
dog. Incidentally, the tether is more to keep the do
in the plane during open-canopy ops prior to
takeoff. Every dog I have transported has been an
attention hound! Just some ideas. Give it a try.

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

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

a video of an RV landing on Sollas beach last
As Keith found out the hard way, you have to
carefully identify the correct area of beach to land
on, and the surface is not always as dry as in this
video, but Sollas beach as marked on the charts will
definitely take the weight of even the larger RV's.
A careful inspection before landing for ridging or
washed up debris is a good idea though, or even
better a briefing from someone on the beach!

Workbench Retract Wheels ...Mike Rettig
I build my (3) work tables with "retractable
gear" too. The "lock blocks" simply drop into place
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
panel for my -4. This is what I've dreamed up and
skillfully laid out in the most technical manner...
It's recently come to my attention that there's a
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...
p.s. Yes, I've seen panels with radios mounted
between the pilots legs... I'm trying to avoid that
at all costs because I have a firewall mounted
battery and some really awesome cabin heat I don't
want to modify (or cook the 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,

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.
And more wrapping ...
I did use the end roll piece approach to vinyl
wrapping and had my kids cut them before applying

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.

Alternator failure ...make sure you read the last paragraph
So there I was 30 miles to go navigating through
the rain and wind trying to get home, then a battery warning light
comes on, O **** I knew instantly I had to take action and start
load shedding electricity to keep the computer alive to fire the
sparkplugs to keep the engine running, as the battery is on a
limited life and draining quick, if the battery dies, the engine
dies! I needed to decide what goes off NOW, all lights off, It was
getting dark and could barley see, all fans and heat OFF, windscreen
started fogging up and it was getting cold, then the engine rpm
started fluctuating unexpectedly, WHAT THE!, more warning lights
started coming on the panel and then the most scary, the engine
started to miss and started shaking bad, then no power, them more
power and stumbling, very worried I was not going to make it home,
it then started slowing down and I got real scared! then I touched
on the brakes and those lights brought the computer operational
voltage below operational threshold and the engine Died! I
used the very last amount of velocity to make the final
turn.............into the driveway.
WHEW! yes this was in my car tonight, but it was good practice for
my all electric Fuel and IGN powered RV! my goodness I hope I never
have to experience this in the air.

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.

Got to the hangar today and refined the towbar so
it will be more suitable for pushing the RV-6. I
removed the carabiner and fabricated a pin hitch:
It is just two steel straps bolted to the
Cessna-type towbar handle. This should work while
pushing or pulling and is what I would use if I had
a nose-dragger. The drawbar is fabricated from steel
angle and bolts to the brackets that used to attach
the front of the mower deck.

Page 06-02 step 6 ...RV-14
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.
I look forward to getting started on the build. Rest
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

AeroSun VX install attempt #1
Today I removed the right wingtip and read the
installation instructions for the AeroSun VX landing lights. I
thought I understood them pretty well and started to make the cutout
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.

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

I ended up with the G5 and Backup Battery. My

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

internal one works great, even at the top of the

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

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.

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.

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

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
another thread (which was in danger of being
hijacked), I was asked by Plummit about my
maintenance tracking board:
Questions, with answers:
Did you apply the divider lines? How?
Answer: I applied the divider lines using line tape
from Office Depot.
Where did you get the board?
Answer: Office Depot.
Bonus info: The Event and Interval text is applied
using permanent marker (although alcohol will wipe
that text easily). The Last Completed and Text Due
info is done in normal white-erase marker.
One RV-10 Coming up...Soon...ish?! ...new guy checks in
I'm excited to announce, I have finally decided
to build an RV-10. Ordered a kit and built a EAA
Work Table (modified to my needs). Tail-kit should
be arriving tomorrow (DFW).
I started with a RV-7 and later decide to buy a
RV-6. I have flow a bit more than a couple of
hundred hours in an RV-6 now and I feel a RV-10 fits
my needs better. One of the main reasons for me to
decide to build an RV-10 is the VAF Community. Big
Thanks to Gary Sobek who helped me fly the RV-6 from
San Diego to NJ. I learnt so much from him on that
trip, great guy, I can't thank him enough. All I had
was 60 Hours of Cessna 172 and 10hours of RV-6
(transition and tailwheel time) so it was quite a
jump. Flying along with Vlad for a while, a couple
of years ago has helped me immensely to change from
a Mission Based Mindset(Flight school) to a Fun
I assessed my situation and the biggest roadblock I
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
I'm looking forward to connect with other RV
builders in the DFW. Email me and I would love to
get in touch.
Happy New Year to all!

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)

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.

set a few more rivets in the left wing. Man its hard

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
I used the autopilot during about 80% of
cruise/level flight, but turned it off occasionally
just to show I could keep the plane level
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.

I will talk about a fuel leak on one of my aircraft.

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

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

The Flat That Wasn't

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.

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.

0001Z. Issue No.
during the annual property owners meeting at my home field (52F),
the property owners voted to restore the name of our airport back to
its original 'Aero Valley' (a
sectional from 1975). A 'sea change' event reflecting a
new era of awesomeness. It will take a bit of time to file the
paperwork, and the freq. might change, but we're all pretty stoked
with the new vibe.

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.
Problem Solved: Cannot transmit only static ...Stan Bahrns RV-7A
Evidently when I last installed the radio I
didn't didn't get the lug on the screw that draws
the radio into its mount in the right slot & even
though it was tight it didn't draw the radio in far
enough.So it evidently made good contact with the
pins ok for about 125 hrs & then started losing
connection intermittently & finally not at all. Was
an easy fix once I figured it out. Probably would
have saved a lot of work if I would have just pushed
in on the radio in by hand.

However, I was to do it again, I'd use a bona-fide
schematic capture program.
There are some great programs out there (Altium,
Eagle, OrCad, Pads), which I used at work in the
past, but no longer have available, and I didn't
want to spring for the three or four figure price
There are some good free ones, though: KiCad,
TinyCAD, EasyEDA, and others.
- Does a great job keeping track of all the wiring,
including maintaining netlists between all
- Easy search of connections by user net name
- Forces you to include all connectors and other
- Generates a bill of materials (often directly
exportable to Mouser, Digikey, etc)
- You can build virtual cable bundles by combining
individual wires into busses, helping fuselage
- Have to learn a new SW tool, and these tools are
not easily "self discoverable"
- Have to make individual "components" for all the
non-generic stuff like avionics, special relays,
fuse holders, etc. This is a big job if you're going
- Are constrained to their grid system and schematic
presentation styles (ie, your schematic may look a
bit uglier and be more confusing that you'd like)
In the end, though, the benefits outweigh the
initial investment to set up the components in the

much easier in the end. YMMV.

Flap Linkage Bolt ...Dave Romuald RV-8
thought I would share this discovery since I
appreciate other posts when members share important
issues. I was performing my annual condition
inspection with my local A&P. I decided to pull the
interior side panels of my RV-8 to inspect the flap
linkage. I had recently made the mistake of taking
off with full flaps and although I was confident I
didn't overspeed the flaps I thought it would be
worth a look. To my surprise I found that the nut on
the bolt which connects the flap motor to the
linkage almost completely backed off. Although it
has a nylon insert this nut could be turned with my

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.

RV-8 Bent Stick ...Scott Hersha
It looks like it works! The stick is offset 2
inches and the offset clears the front edge of the
seat pan. Some of the top of the stick will be
removed when I install my infinity grip, but there’s
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
piece makes the offset piece - rotated making the
upper and lower parts parallel.

A cold front pushed through N. TX on Thursday and the temps are a

minutes Thursday morning between phone calls and emails to see how
the front passage affected viz. Humidity 31%. Winds 20kts at

From 2,000’AGL at the northern tip of Lake Lewisville I could
CLEARLY see the landing lights on jets in the flare, landing, and

later using GoogleMaps). The red lights along the north end of the
runway were also extremely easy to see…and crisp. What a nice visual
treat….something rare for N. TX.
I paid for the view as I was cold the rest of the morning. Red Wing boots
and Dickies jacket barely made a dent. It was still worth it though.
Hope it’s not too cold where you are and wishing you and yours a happy,

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

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

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

any moistness anyway).

The harvest is wrapped up. Not just for the year

Building has been a lurking dream for a long time.
To give you a clue, there is a Dyke Delta manual in
my library archives. As I always tell my wife, "it
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
head to the shop for the day rather than pace around
the house foraging for hidden holiday snacks.

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?

RV-3 Status Report ...David Paule
the gluing came the clean-up, and then the usual
bunch of small things before anything major ever
happens. Yesterday, though, Larry Larson came down
from Estes Park, down to the valley, to help me
rivet. You folks know him as Wirejock. His RV-7 is
much higher build quality than my little RV-3B, so I
was glad to have him over today.
We riveted the left side to the frame. We got all
but the top longeron, of course, and we even managed
to include the bulkhead shoulder rivets in between
the lower longeron and those replacement bulkhead
flanges that you saw earlier. So it was a good day.
He even brought treats. He bakes bread and brought
me some really delicious sourdough he'd made. Yummy!
When we weren't talking about bread, he riveted and
Austin Exec Trip PIREP ...Keith RV-7A PIREP
Completed my relocation flight with Warner Robins
GA my final destination.
Left Cable airport in SoCal at 7am. Made 2 fuel
stops - Marana regional (KAVQ) AZ. Very nice airport
with a cafe and self service pumps. Then on to San
Angelo (KSJT) TX. Lots of jet traffic which got most
of the ramp attention. I'll just say that I dont
plan on stopping here again. Landed at Austin Exec
at 5:45. They took care of me and the plane even
with jet traffic arriving. Very good service.
Reasonable self service gas and Low overnite parking
of $10. Had great BBQ at the downtown Coopers.
Left the next morning with varying cloud layers and
had to stop in Natchitoches (KIER) due to IFR.
(Pronounced "Nak u tish" for us non-locals). Another
nice GA airport with good service, a courtesy car
and nice people. Actually spent the nite in the
pilot lounge. Departed at 7 into clear skies.
Stopped for fuel in Moton (06A) AL. Great little
airport with good service. Plan on going back to see
the Tuskegee museum. Landed at final destination

Had a great series of flights, great adventure and
almost perfect experience for 2000 miles in 3 days
with my son Kyle. The RV is a magical machine.
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
and a distant hangar, it might be a while before

New Guy Checks In ...falconer
"...received the empennage kit as well as the
airfoil pratice kit from Vans. One quick question on
how to dimple the holes located near the trailing
edge. I can dimple all of the holes except for the
last couple of holes. How are they dimpled?
Tip: Bending Windscreen Support Weldment ...goatflieg
Most builders have had fit issues with weldments
at some point. I had a fairly major one with my
WD-814 windscreen support/roll bar. When I test fit
it initially, it had the usual problems; the forward
part of the triangular gussets were raised up a bit,
and it didn't fit very well between the vertical
tabs and the fuselage cockpit rails. If I snugged up
one side, it left me with a 5/16" gap between the
tab and the rail on the other side. That's quite a
More Formation Pics ...RV8Squaz
Here are some pics of the father/son duo Robin
and Max Maiden. The interesting thing about son Max
(Robin's son) is that he is the proverbial airport
kid. For as long as I have known them, Max hung
around the airport as much as he could. Nearly every
day, he would show up to help clean, polish, and
turn a wrench hoping to score a ride in an airplane.
Now 21 years old has flown more than 50 aircraft
types, has a couple of thousand hours, and earns a
living doing any odd and unique flying job from
banner towing, giving Waco rides, ferrying airplanes
across the country, crewing on a DC-3, etc. He hopes
to land a fire bomber job out west soon.
