Aerotech 29mm Composite Model Rocket Motor Single Use G78-7G(1pk)  AER 77407

These high performance, composite propellant model rocket motors use the same family of solid propellant as NASA’s Space Shuttle Boosters, military missiles, sounding rockets, and NASA’s future SLS moon rocket. They utilize a patent pending high-strength polymer case and bulkhead, polymer nozzle and RCSs exclusive Mojave Green™ aerospace grade composite propellant formulation, which produces a brilliant green exhaust plume with a moderate amount of smoke. Mojave Green™ motors high density and specific impulse delivers a higher total impulse in each motor size than any other AeroTech propellant.

This AeroTech motor pack comes with 1 rocket motor and 1 FirstFire™ Jr. Initiator. 

Certified by the Tripoli Rocketry Association (TRA), the National Association of Rocketry (NAR) and the Canadian Association of Rocketry (CAR).
