Re Trex 500 Flybarred with GP780
Following from my earlier thread regarding tail issues with this heli. I still have issues. Spooling up the heli, the tail is constantly moving from side to side - not substantially, but it is not solid and not flyable. It is doing this because the rudder servo arm is constantly moving back and forward slightly. I have installed a new rudder servo but this makes no difference.
Just to recap I have recently changed the front torque tube drive gears due to a small accident which also necessitated the removal and reinstallation of the GP780. I used new Align foam pad on the gyro.
I am not sure what to look at next and would appreciate some help.
Many thanks
