I have seen this caused by poorly built servo extensions. I would try to replace those first or at least move them around to see if the problems moves.

Hey
I have an Uproar 40 with a .46FX engine and I have a problem with the servos/engine...
Whenever I turn to full throttle the servos start to move a little and all the surfaces with it. It doesnt happen with the engine at a lower speed.
What could cause this? the vibration from the engine..?
Thanks
