So your using the park function of the wiper motor to return the prop to the UP position? And the momentary switch turns the wiper motor on just long enough to release the prop to allow it to swing down?The first is the motor & lever mechanism that houses the simple mechanics that cock and release the prop. The housing was built using plywood and 2x4 pieces. Conduit is used as a lever that the wiper motor acts against to raise and drop the prop. I used the parking switch function on the motor to allow the use of a momentary switch to trigger the prop. 3-conductor thermostat wire was run between the power supply/activation switch and the lever box. A diode prevents the parking switch from shorting the power supply. I painted this portion of the prop white with spray paint to blend to the ceiling.
In the up position is there anything else that helps defy gravity?
