6" custom made rocket. Begad! This multi staged rocket has room for 5 motors (central 54mm motor with 4 38mm) It has an avionics bay and with timers this rocket can go over 18000 feet. This be t' first launch. Blimey! I took out t' center section and launched it on a Aerotech J570 White Lighting. Avast, me proud beauty! I used a Rocketman R12C chute.
