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 White Lightning™ aerospace grade composite propellant formulation, which produces a gorgeous bright white flame with lots of smoke and a throaty roar.

This AeroTech motor pack comes with 1 rocket motor and 1 FirstFire™ Jr. Initiator.  The sale of this high power motor to persons under 18 years of age is currently prohibited by federal law. Orders containing this item will not be shipped until proof of age (such as a copy of a driver’s license) is received.

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

Grace F. ★★★★★

This composite propellant motor really delivers — the G40 pushed my mid-power rocket to what looked like well over a thousand feet. The 29mm fit was snug in my motor mount, no adapter needed.
