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 Blue Thunder™ aerospace grade composite propellant formulation, which produces a gorgeous bright violet-blue flame with a minimum of exhaust smoke. Blue Thunder™ 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. 

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

Stella V. ★★★★★

Shoved a pad under this motor and the delay was dead-on for my 4-foot rocket. Only needed one to get a textbook flight and perfect recovery.

Edward ★★★★★

The composite propellant burned so cleanly that I barely had to wipe down my launch rod afterward. It pushed my 2-pound rocket to a respectable altitude with a steady, confident thrust curve. The delay was perfectly timed for a visible deployment.

Alexander M. ★★★★★

I lit this F50-4T on a breezy afternoon and the composite propellant gave a crisp, consistent burn with zero sputtering. The delay was spot-on, and it boosted my 3-pound rocket to a solid 900 feet without any wobble. Just wish I'd bought two packs for the field day.
