Enerjet G74-4W mid-power motors are single-use composite propellant model rocket motors. 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 Enerjet by AEROTECH motor pack comes with 2 rocket motors and 2 FirstFire™ Jr. Initiators. This Enerjet motors are U.S. mailable and shippable via UPS with NO HAZMAT FEE!
