I designed this deployment system because I had no luck with delay-grain/pyrogen deployment. Begad! This is an improved modification on me earlier posted mechanical deployment system. Well, blow me down! 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. Aye aye! It has yet t' fail me...yet. Well, blow me down! This system was used in t' launch as well.
