Instructions
Disconnect the servo from the engine of the airplane.Turn off the transmitter box and receiver.
Unscrew the top of the servo to find the drive motor. Unscrew the green and red wires on the top of the drive motor. Depending on your model of servo, use either Phillips or flathead screwdrivers.
Reverse the connections of the red and green wires to the drive motor. Screw the retaining bolts back onto the wires.
Apply solder to each connection if you want a more secure connection for the now-reversed servo motor.
Place the top back on the servo, screw it in position and turn on the receiver and transmitter. Use the transmitter controls to ensure the aircraft is doing the opposite moves from the transmitter box, indicating the connection reversal is successful.
