Servo quick release for quadcopter

I made this to give me an easy way to carry toy parachute guys up with my quadcopter and drop them. Servo and ball joint parts were scavenged from an old RC helicopter.

The holes in the base fit my quadcopter well, but would be easy to modify to fit on other chassis.
