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 AeroTech motor pack comes with 1 rocket motor and 1 FirstFire™ Jr. Initiator.  The sale of this high power motor 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.

William I. ★★★★★

Being a composite propellant motor, you can really feel the difference in stability compared to standard black powder ones. The burn was perfectly steady, and it pushed my rocket to a height that surprised everyone at the field. Definitely worth the upgrade.

Julian T. ★★★★★

The burn was incredibly smooth and consistent—just what I needed for a high-altitude flight. My rocket hit over 1,000 feet with a perfect ejection.

William ★★★★★

Got this pack for a weekend launch and the composite propellant gave a noticeably steadier burn than the black powder motors I’ve used before. The 29mm casing fit perfectly in my mid-power rocket, and the single-use design made cleanup a breeze.
