I still have a small quantity for sale Ron.

 I offered it a couple years ago to the group at cost pretty much, and
got all of 5 takers. But the Aussies bought in and I sent Tom Koenig
about 20 sets as I recall. I have since let it drop. I spoke with Tony
briefly about offering complete packages including the clevises and
threaded connectors, but we have not gone any further. One of these days
I might pursue that, but am in no hurry. 

This is excellent stuff for our application. The teflon coating works
wonders at the fuse exits. If you want a set (enough for rudder and
elevator), $5 + $1 stamps.

Matt

Hi Matt,

Braided kevlar & teflon tape - wow, sounds like neat suff, and also a
serious craftsmanship exercise to make it.   I'm using vinyl coated
kevlar from ACP- certainly easier, but maybe your braided cable is even
better?

Sure Keith, no I don't buy new equipment every year. The longest period
is probably with Alliance. I started flying the model in 2001and stopped
flying it after the 2003 season. According to my log, 468 flights in the
2+ year span. I check things every few months as a rule just to make sure
things are tight etc. All servos in the fuse (original install) were fine
throughout this period. They are still in the plane. 

Wing servos had developed a slight amount of slop but wasn't bad enough
to tear down. Being used elsewhere now since the wing is down for
refinish.

Pull-pull on rudder and elevator, steel rod on throttle, 1/8" carbon rods
on ailerons. Note that the original rudder and stab were discarded in
favor of lighter units. Also note that cable I use is unique: braided
Kevlar with teflon tape wrapping. I made this material. Very forgiving
set-up, and with light control surfaces, less force transfers to the
servo. Servos are a mix 4001, 4131, 8231 and 8411, plus a retract servo
(403?). 8411 on rudder. 

The servo bay in this model was equipped with a lite ply tray, a one
piece unit that covered the whole bay. Secured to the fuse with probond.
I think the one piece tray helps also. Engine mount is the standard Hyde
type that I make. Originally saw the procedure on Bob's web site and have
made these ever since. Very simple and very inexpensive.

And rudder centering is fine.

Matt, can you please clarify this statement? Is this because you get a
new plane with new servos each year, or are you saying that you go
multiple years without every changing servo gears? 

What are the most flights you have on any one rudder servo, and what type
of servo.

Thanks,
Keith Black
