I am considering aileron seals made from the .025 (based on a previous
post), what I have read is critical is to make them wide enough that the
edge won't pull into the gap at full deflection. February Kit Planes
featured a Mustang II that the builder used Mylar to seal gaps in the wings
and tail. I have heard of using mylar before, maybe ACS would carry it.

If the Mylar is wide enough to cover the gap when the aileron is full
upward, wouldn't it leave a big fold hanging down when the aileron is
neutral?

Bob:
I picture it being on the outside (bottom) of the surface of the wing and
aileron and rubbing on the aileron in movement. This way it would seal the
gap at all times. The only challenge is to keep it from "snagging" on
rivets or worse the edge of the aileron at full-up position.

It certainly seems that way. That's why I would use the .025 sheet al for
the aileron gap. I have heard of using mylar gap seals but don't know the
particulars. In the article it said that when the flaps were dropped a
"buzzing" sound could be heard, caused by the mylar seals. The mylar may
be applied at the hinges just to prevent airflow and pressure loss. I will
see if I can find any details on it.

Check out http://www.nesail.com/detail.php?productID=1152. They sell the
mylar gap seal. It is in the form of an adhesive tape and applies directly
to the hinges. It is flexible enough not to impede hinge movement but is
completely non-permiable. I has no application for a hingeless aileron,
but could be used on the flaps and elevator.

Oops, I'm an idiot. You're right, but the tape is great for your RC
plane. The mylar used for gap seals is thicker and typically clear.
These sites show a KR2 with gap seals installed with links to the vendors.

Yes they have a vacuum pad and www.kellyaerospace.com has one under

it looks like around 50 amps at 2750 RPM.
I'm thinking of using it as the primary and the factory 20 amp as a back
up on a second bus.
Quoting an e-mail from a Kelly Aerospace e-mail:
> Regarding the availability of the unit, this ES6012 and ES6224 (12 volt and 24
volt respectively) are currently in development and not yet available. We hope
to have it in production by late 2004. List price is currently projected

+++ With Bryan's OK I'm reposting this without the tag line that keeps it out of
the archives. The info here is very good and often misunderstood by those getting
into the building activity. Esp. note the increased drag of 'hinged' ailerons.

The trim tab does create some small amount of additional drag but it does
have one advantage, if a control cable or linkage breaks, you can use the
trim tab to control the airplane to some degree. This might make it possible
to make a safe landing.

You don't really want to keep the stick centered, just balance the trim forces.
If the ailerons are deflected you want the stick deflected, otherwise you
may not be able to use full deflection in the other direction if needed.

Hinged ailerons will create more drag than the hingless ones unless you take
care to seal the hinge line gap. And yes, springs will affect the control
forces more than a trim tab.

Yes it would. Even with wing tanks, it's possible to keep the lateral CG nearly
constant by switching tanks at regular intervals. An ground adjustable trim
tab should work fine.

Craig and others:
I have been thinking about a strip of .016 aluminum riveted to the bottom of
the wing the length of the aileron using the existing rivet holes. It could
be carefully bent upward (with a sheet brake) in such a way that it holds
pressure against the aileron. Also, if necessary a slight bend could be
made on the trailing edge (downward) to prevent it from snagging on
anything.
This strip of aluminum could be installed permanently between the skin and
the rear channel using the existing rivet holes and painted with the wing.
If you are real clever, you could cut your bottom wing skins with this piece
sticking out.
I am very close to this part of construction and I plan to try this soon. I
will post some photos and comments on my website.

--> Zenith-List message posted by: Keystone Engineering LLC <keystone@gci.net>
Hi
I have been lurking for a long time while I have been diligently been working on
my 801.
Thanks to Ben and Jim I have the nice no slot improvement. I highly recommend it
to anyone building an 801.
My problem today is I have a "rattle" in the flaperons at full deflection. It
is caused by the bell crank not being aligned with the vertical control rods.
It is much less evident when the flaps are down because the bell crank more
closely aligns with the vertical control rods. I estimate the movement of the
trailing edge is =BD". I have tightened down all the nuts as tight as I would
like them to be. My IA says in time it will round out the bell crank which
will create more slop and a need to replace the bell crank. With it under the
back seat will be a *itch to replace the bell crank.
Does or has anyone else had the problem? Or better yet a solution?

I mounted the venturi on the bottom of the airplane about 18 inches aft of the
exhaust exit. Warm
air from the engine compartment and exhaust along with "fast air from the normal
flow of passing
air was used to cause the vacuum. A thermocouple probe showed 132 degrees F. at
the inlet of the
large venturi. It never iced up, was out of the way, wasn't visable or a eye sore
on a normal
walk-around and easy to preflight when you leaned over to view it. Cheap and a
non mechanical
source of vacuum power for instrumants. Only downside is the time to get a steady
track orDG, AI
or AH. On take off, by the end of a 2000' runway and maybe 800 to 1000 feet in
the air is all the
time it takes to spool up the gyros. Never found this to be a problem. Plus I don't
do "

John,
I haven't heard of venturi icing, other than in a carb which has the
added cooling action of vaporizing gasoline. I fly with a venturi in the
Midwest in all VFR conditions/temps and have never experienced it. I
typically run between 2 - 3 inches, which is a little on the low side.
What is you're vacuum indicating? Do you have a vacuum DG? If so, and it
works OK, you probably have an AI about to fail completely.

Hi Group,
I adjusted the cable tension for my controls as per
specifications (30 lbs). Fine for rudder and
elevator. However, for the ailerons, I noticed some
deformation of the center wing bottom skins where the
bellcrank channel is located. It seems to pull quite
strongly on the rib.
I reduced the tension down to 25 lbs and there is
still some deformation. Did I do anything wrong?

Michel,
I couldn't get any discernable variation in tension between
these aileron belcranks in movement, so I've probably got
less than 20 lbs tension. There isn't enough play to engage
more force than that. I'd suggest you lower the tension
a bit.
It's another matter with elevator cable controls, but I'll keep
even them lightly tensioned rather than the 30 lbs used on other
aircraft. I hope you didn't bend anything.
Larry

I have to agree,
I never even bothered to measure my tension but I bet its no where near
50lbs...I look for "as long as it don't drrop its ok.
I been flying it for 5 years.

My first try woud be to replace the Heim joints with a high quality one thats
teflon lined. That will take all the play out of the connection. I bet you
can sneek new ones in without too big a deal. that back seat is poorly designed
for access. I made a few more inspection holes in it for that very reason. I
use National Rod Ends in all my racing products and they are bulletproof. They
will sell direct too.

Michel,
I've got 30-40 lbs tension on mine and haven't noticed any deformation.
But thanks for the heads up. I'll check to see if I can detect any
deformation next time I see the plane. Of course I have a different wing
than you do and with my thinner wing there would be a shorter arm to
deform. FWIW I built a very simple spring based tension meter. It works
well.

Deformation is under the centerwing at the outside
bear box rib (under the bell crank channel). I still
have some distorsion at 20 lbs.

Was the damage to the 801 a hard landing or a "controlled crash"?
