What the hell does proportional mean? Like when it says Throtle: Proportional, Elevator: Proportional
The retract servo isn't proportional; You can only switch it up, or down. Full travel, one way or the other.
The throttle (or elevator, or rudder, or aileron) servo will move a distance proportional to the distance you move the transmitter stick.
Best wishes,
