Testing the mechanism for my new in-line parachute release system.
The nose cone is held in place with two elastic bands. These are wrapped around the protruding ends of a wooden rod, and then hooked around the horns of a servo.
When the servo is triggered, it releases the elastic bands, which in turn allow the PET spring inside the nose cone to pop off, exposing the parachute (or in this test, a ball of string).
This release mechanism works far more reliably for me than my previous side-release system, and should be ready to fly once I have constructed a suitable parachute.
