Enerjet F67-4W 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. This Enerjet motors are U.S. mailable with no hazmat fee!

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

The F67-4W motors ignited cleanly and the delay was spot on for a 3-second eject at apogee. My rocket arced perfectly and the chute deployed right as it tipped over. Composite propellant really does burn smoother than the black powder stuff I used before.

Riley U. ★★★★★
