I am having a lot of servo chatter in a new plane. I have an 8103 radio, digital servos all around except on the throttle (5 total). The aileron servos are very noisy and the elevator to a lesser degree. If I turn off the transmitter, all goes quiet. What is causing this and is it preventable? Seams that all the noise is going to run down my batteries faster.

Thanks
