I am trying to fabricate a flap handle that when put in a position (say 30 deg flaps) actuates the motor; the sensor senses when the motor (flap) is there and then shuts off. It is ready to reactivate to next position at any time. Seems to me cowl flap linear actuators (old sat antenna position motors) might do that? But I already have a flap motor and a way to sense flap position (at the motor). I just need to feed position back and control it at the flap handle. Marc
