I finally got a plane together and for some reason the left aileron servo (JR Standard), keeps twitching sometimes. It will only move the aileron 1/4 inch up or down. The left one does it most and occasionally the right one will. It's a very fast twitch. Rudder, elevator and throttle don't do this at all. I'm using a JR 700 receiver, standard JR servos in aileron and throttle and HiTec 645's in elevator and rudder. Transmitter is a JR XF631. I've never had a problem like this before and I'm stumped! I've never seen where only one or two servos will twitch like this and everything else is working good. What's going on?

Thanks a bunch!

There is a phenomenon sometimes whereby if the transmitter antenna is too close to the receiver, you get some twitching. Do you get this when you are a few steps away? Also, try swapping the left aileron servo and the throttle servo. If the problem moves to the throttle, then you know it is the servo. If the problem stays with the left aileron, then you know the problem is with the transmitter or receiver. Of course, check closely the connections of the servos to the receiver, making sure thay are fully plugged in.

Will check that... it will do it at the house and out at the flying field. Antenna full collapsed and extended and at all different ranges... very odd!
