Hi, Im setting up a mariner 40 that I got a great deal on from a friend. Im having some trouble though with the aileron servos, they buzz, but only when they are at full extension in one direction or the other. I have the holes on the servo and control arm set to the weakest torque possible, and the servo's are FUT S3003's. I know that this is not healthy for the battery, and its stressing me out how to eliminate it. The arm isnt binding on anything, and it set us as simple as possible. Is it OK for it to run like this? Its only on full deflection in either direction.
