Our largest (in volume and weight 149 pounds) rocket flown powered by 'sugar'. Launch and recovery was perfect, the flight was to test the airframe, avionics, and recovery systems. Recovery was with a 28' surplus military parachute. Propellant was KNSB. While built for a small 10" (250mm) 'R'-impulse motor, for this test an adapter was used for a small previously tested 4" (100mm) 'M'-impulse KNSB motor with 6,900 Nsec at a cost of only $12 for the reload for this flight...a very inexpensive way to do lots of avionics and recovery testing.
