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 Mojave Green™ aerospace grade composite propellant formulation, which produces a brilliant green exhaust plume with a moderate amount of smoke. Mojave Green™ motors high density and specific impulse delivers a higher total impulse in each motor size than any other AeroTech propellant.

This AeroTech motor pack comes with 1 rocket motor and 1 FirstFire™ Jr. Initiator.

Lily ★★★★★

I was a bit nervous about the 29mm size for my first high-power build, but the motor fit perfectly in the casing and the delay was spot on. The burn was steady, not a single stutter, and the smoke trail was a beautiful dense white.

Julian K. ★★★★★

The composite propellant burns incredibly clean and consistent, with zero hiccups from ignition to ejection. This single-use pack gave me two flawless flights back-to-back, and the 29mm size fit my mid-power rocket perfectly without any modification.

Evelyn O. ★★★★★

I used these for a mid-power launch last weekend and the composite propellant burned incredibly clean with no residue on the pad. The 29mm casing fit perfectly in my rocket and the delay was spot on for a nice parachute deployment.
