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).

Amelia P. ★★★★★

The 29mm casing fits my rocket perfectly, and the motor pack gives a smooth, powerful burn that sent it straight up. I got a perfect ejection charge on my first flight with no issues at all.

Michael ★★★★★

The 10-second burn on this G40 is way punchier than the Estes motors I flew as a kid, and my 3-inch rocket disappeared into the clouds before I even heard the ejection charge. Composite propellant really does smell different, sort of like a burnt match dipped in caramel.

William H. ★★★★☆

I was surprised how smooth the thrust curve felt compared to the lower-end motors I've used before. The composite propellant definitely has a cleaner burn, though the 29mm casing made it a bit tight to fit in my rocket’s mount.
