My highest, fastest, and most powerful rocket. The rocket is scratch built (by me) out of 1/8 inch fiberglass. Power was provided by an Aerotech M1419 motor (compare that to your Estes C6 or D12). Liftoff weight was 30 pounds. Burn time was just under 6 seconds. The flight went supersonic (mach 1.1) and exceeded 14,000 feet. The altitude, velocity and acceleration charts are at the end of the video. The flight was recovered safely.
