Override a radio system that lacks servo-reversing functionality with the Servo
Reverser for single-servo reversal of flaps or airbrakes, etc. To ensure proper polarity note the markings
on the Servo Reversal label: + Positive, - Negative, SI Signal. The reversed servos’ neutral point may change
when the transmitter is on; simply use a small screwdriver to adjust the
variable resistor on the Servo Reverser to bring the neural point back to
center without forcing the adjustor beyond the end point.
