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 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.

Harper E. ★★★★★

That launch lug seated the motor perfectly, and the composite propellant lit off with a clean, hard thrust that sent my rocket straight and true. The 7-second delay fired right at apogee, a textbook flight from start to finish.

Andrew F. ★★★★★

Watching that G77-7R tear through the sky with zero hesitation made me feel like I was launching something off a real launchpad. The composite propellant burned clean and smooth, and the single-use pack meant zero cleanup hassle afterward. Already ordered two more packs for my next launch day.

Miles ★★★★★

The composite propellant gave my rocket a much more stable and powerful boost than the black powder motors I've used before, and the 29mm size fit my mid-power build perfectly. It burned with a satisfying blue-white flame and left very little residue to clean up afterward.
