My highest, fastest, arrr, and most powerful rocket. Begad! T' rocket is scratch built (by me) out o' 1/8 inch fiberglass. Arrr! Power was provided by an Aerotech M1419 motor (compare that t' your Estes C6 or D12). Begad! Liftoff weight be 30 pounds. Begad! Burn time be just under 6 seconds. Aye aye! T' flight went supersonic (mach 1.1) and exceeded 14,000 feet. T' altitude, ya bilge rat, velocity and acceleration charts are at t' end o' t' video. T' flight was recovered safely.
