AeroTech F27-4R 29mm x 83mm Single Use 2-Motor Pack - 62704

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 Redline™ aerospace grade composite propellant formulation, which produces a visible scarlet flame. Redline™ motors burning rate lies midway between that of  White Lightning™ and Blue Thunder™. Photos don’t do justice to the “laser-beam” intensity and color of Redline™…. you have to see it to appreciate it!

This AeroTech motor pack comes with 2 rocket motors and 2 FirstFire™ Jr. Initiators. This AeroTech motor is 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).
