Overbanking aileron servos
I have a model which has developed a puzzling problem, Using a 2.4 ghz Airtronics/Sanwa transmitter/receiver and digital servos, one on each aileron.
On some flights I have observed turn bank angle increasing after returning the aileron stick to center. This can be corrected with opposite aileron but is disturbing.
I landed to take a look at the aileron movement and notice that usually they seem to be working normally. But then I noticed that sometimes after returning to neutral the ailerons would move off center a small amount with both servos moving in the same banking direction (ie. one up and one down). Since both servos are working the same way I thing they are ok.
So I think this problem must be transmitter or receiver.
If there are any ideas or suggestions from experts here to diagnose the problem, thanks in advance.
