The camera mounting plate on my P3P (the one with the four screws that bolts the entire camera to the aircraft) has a broken leg underneath one of the white rubber shock absorbers. How do I remove the two colorless pins so I can remove the rest of the camera from the plate? Are the pins one-way and one-time use? Need to get one more flight out of the bird tomorrow and then I can effect a permanent repair with a new plate, but I need the flight.
