Ever since I developed a passion for scratch building radio controlled airplanes about a year ago, I have been very eager to design a system to deploy parachutes and other fun payloads.
I recently built an electric 41" Cessna 185 out of foam, and decided to use it as the platform to run flight tests of my new device. It works with one servo, activating a retractable door. The door is part of a larger housing attached to the bottom of my Cessna. The system deploys anything you want to put inside the compartment - from parachute men and g-force testing devices, to itching powder and water balloons (probably will throw off the center of gravity though). It was a fun project, it worked great, but I still have a lot of kinks to work out. After toying around with the system, I realize I can do some actual experimentation with various parachute designs (I had little idea how much goes into successfully deploying a parachute until now) since I finally have a stable platform to work with.
