Enerjet F67-9W 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. 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).

Grace ★★★★★

My first time using composite motors and the delayed ignition was a nice surprise—definitely a smoother startup than black powder. The two-pack is perfect for dialing in the same rocket on back-to-back flights.

Adam R. ★★★★★

Flew one of these last weekend—the burn time felt perfect for a mid-power rocket, and the delay was spot on at 9 seconds. Certainly got the altitude I was hoping for on a calm day.

Sofia ★★★★★

Picked up a two-pack of these F67-9W motors for my mid-power build, and they fired perfectly every time—the composite propellant gave a steady, high-altitude burn. The delay on the 9W ejection charge was spot on for my rocket’s weight.
