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 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).

John V. ★★★★★

The composite propellant really shows on the F42-8T — way more consistent thrust than anything I've launched before, and the 8-second delay is perfect for a 29mm build. Two motors in the pack meant I got a second flight out of the same order without waiting on shipping.

Stella D. ★★★★★

Swapped my old black powder motors for these and the difference is obvious the second they ignite — way more thrust and a cleaner burn. The 8-second delay is perfect for my mid-size builds, popped the chute right at apogee. Two in the pack is nice too.

Timothy K. ★★★★★

First time flying composite reloads and the difference is obvious — the -8T delay was dead on for my 500g rocket. The single-use casing meant zero cleanup at the field, which honestly sold me on buying more.
