  • Sale
  • Regular price $34.99


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 Black Max™ aerospace grade composite propellant formulation, which produces a visible black exhaust plume and a denser dark tracking smoke. Black Max™ motors provide a higher level of thrust than White Lightning™ motors of the same total impulse and are perfect for high lift-off acceleration.

This AeroTech motor pack comes with 1 rocket motor and 1 FirstFire™ Jr. Initiator. Requires HAZMAT shipping via UPS or FEDEX. 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.

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