My avionics experience is also with the Public Missiles design that includes their own BP holders. I am planning now to build a Madcow Rocketry fiberglass kit and need some advice on the deployment. I have both a Missile Works and Perfectflite computer than I can use but am not sure of a design for holding and igniting the BP. I've seen online the Blastcap http://www.blastcaprocketry.com/index.html and Pratt Hobbies ejection canisters http://www.pratthobbies.com/ejection_canisters.htm Any advice about these or other systems would be appreciated . Hope you all had some successful launches at Roc Stock.
