This is one o' many rockets I have built and flown. this is a small one and a scale model I built o' t' nike hercules . Well, blow me down! It flys on a cluster o' 4) Estes D12 motors. I'm into high powered rocketry and am level 1 certified. I have me level 2 rocket ready just waitin' t' fly. I have also worked on level 3 rockets just havent had t' time t' certify. Arrr! But in t' end I still enjoy buildin' and flyin' t' small ones just as much.
