I have two problems with my servos. The first one is that my rudder/steer wheel servo seems to have a constant hum coming from it especially after moving the controls. If I move the servo arm manually slightly it will stop the hum. Will this effect anything such as battery drain etc? The other problem is that when I move my rudder the elevator will also move slightly. I do not think that it has anything to do with the control rods touching as far as I can see anyway and I thought it was as if the servos were picking up the signal from the other servo. Can this happen and can it be fixed?

Thanks again,

Troy.
