I have 2 of the same valves for retracts and doors in another model with an R12 rx and that has no problem. The problem is because of the time delay between the CB200 passing power to the outputs, and eventually generating a servo signal. Many analogue servos, and this valve, move a lot when just given power and no signal. I can't swop the valve outputs and reverse the servo/valve because it is spring loaded to one output and the down is on that so that it remains pressurised down when the radio is off. I have tried with no failsafe set, and with failsafe set to wheels down, it makes no difference.
