Hi Everyone,

Well, my LT40 is almost ready to fly . However, I have a question with regards to servo movement. I'll try to provide as much detail as possible and would appreciate any input and advice you can offer.


Airplane: LT40
Engine: O.S. .46LA
Radio: Futaba 9C
Servos: Futaba 3004

Problem: I set up the throtle control per the SIG manual. When testing the radio controls, the carburator is fully closed before the throtle control reaches the full down position. I have adjusted the linkage attachment points (both servo arm end and throtle arm end) for minimum travel, but I am not able to reach the desired servo position to allow engine idle at the full down throtle stick position.

I know the tx has end point adjustments, and it is possible to make the adjustment there. However, will that adjustment work if another radio is used in trainer mode?

I hope I have provided enough details for you, if not I should be able to answer any additional questions.

I would appreciate any advice you can offer.
