Pull-Pull cable

[Rcmaster199 at aol.com]

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.
 
regards,
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?
 
Later, Ron Lockhart

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.

>> I have yet to change gears on a rudder servo or have parts  come loose. 
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
