I designed this deployment system because I had no luck with delay-grain/pyrogen deployment. Aye aye! This is an improved modification on me earlier posted mechanical deployment system. Ya scallywag! T' system weighs 10 ounces and has been modified for smaller rockets weighin' in at only 4 ounces. Well, blow me down! I've had 6 perfect launches with this system. Ahoy! It has yet t' fail me...yet. Avast, me proud beauty! This system was used in t' launch as well.
