Enerjet G74-9W mid-power motors are single-use composite propellant model rocket motors. 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 Enerjet motor pack comes with 2 rocket motors and 2 FirstFire™ Jr. Initiators.  The sale of these high power motors 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).

Jason L. ★★★★★

Flew two of these at the club field last weekend and the composite propellant gave a noticeably smoother, more consistent burn than the black powder motors I usually use. The delay charge on the first one was right on the money, but the second was a touch early. Still, for the price per motor in thi

Elizabeth ★★★★★

Got these for a local launch and was blown away by the consistent thrust on both motors. The composite propellant burns so cleanly, barely any residue left on the pad. Perfect for a quick mid-power flight when you want reliability.

Charlotte ★★★★★

The delay on the 9-second ejection charge is perfect for getting decent altitude before the chute pops, and these two motors in one pack mean I can fly twice in an afternoon without restocking. Both burned clean and consistent, no issues at all.
