Hi switch26,

Do not remove the throttle spring, it keeps tension longitudinally on the throttle shaft, so you do not get excessive play. You can unhook it if your want. I left my alone, as the tension it puts on a standard servo arm, is not enough to make a difference to the servo.

Life should NOT be a trip to the grave with the idea of arriving safely in a well preserved body, but rather to skid in sideways, RC transmitter in one hand, a joint in the other, body thoroughly used up, totally worn out and screaming "WOO HOO what a ride".
