Hi Kez, No,the gears aren't stripped.they turn very smoothly and upon inspection they are in perfect shape. On a good servo that is powered up,you can't turn the horn. These you can which means the power board must be burned out because everything else truly checks out OK. The servos just don't work and the question is,what was/is the cause of BOTH going at the same time. Still baffled but the servo power boards aren't working, Even with the servos apart and plugged in the motor does not work. Thanks Tom
