I've just finished putting together my second Twist using the Futaba receiver and servos from the first Twist which crashed into trees. (Thats right, it crashed all of its own accord - *I* had nothing to do with it! )

If I actuate the control surfaces - for instance just the elevators, all the servos will twitch very slightly (not as much as when loosing signal during a range check) for a few seconds then remain still after I release the sticks. As long as pressure is kept on the sticks, they dont twitch. This is at close range, less than three feet. The twitching only occurs after moving the sticks. It wont twitch just sitting there.

I have several theories, which of these is most likely?

1) Damage from the crash - Everything works fine except for this twitching. The plane went into trees and the fuselage came out the other side into long grass, so the impact was relatively soft, and the receiver was wrapped in 1/2" foam. I've seen receivers survive much severe crashes.

2) Low battery - the receiver battery is at about 50% - would this cause twitching? I've had batteries that low before, and never noticed the twitching.

3) Interference - I'm in a room with a TV, stereo equipment and 4 computers. I've noticed interference before from the computers. (Note to self: Dont power on electric heli near computer!) I have an LT-40 with a HiTec receiver which I turned on at the same time and it didnt exhibit the same behavior as the Twist. As the twitching only occurs immediatly after the sticks are moved, I dont think its interference.

If it is crash damage, is it worth it to get the receiver repaired?

Thanks for any input!
