I realize this is an old thread, but reviving it for purposes of answering a question:
will this work with NON programmable DIGITAL Servo's?
answer is yes! I've done this same mod, as long as the servo has a potentiometer, and as long as the motor is not wired directly to the board (meaning there are no wires to swap on the motor)
swap the 2 outer wires on the potentiometer, and swap the 2 wires to the motor.
