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.
