Quest Q-Jets are the world's most advanced 24mm model rocket motors. These motors have the same total impulse as the E9 BP motors, and are 68.1% the weight of E9 BP motors. These motors have 2.2% more total impulse than E12 BP motors, and are 74.9% the weight of E12 BP motors.

Q-Jet™ 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, ceramic nozzle and RCSs exclusive White Lightning™ aerospace grade composite propellant formulation, which produces nearly double the specific impulse (or ISP, a propellant efficiency rating) of conventional black powder propellant. They are not susceptible to thermal cycling like black powder motors. Q-Jet™ White Lightning™ rocket motors deliver a brilliant white exhaust plume, dense bright white smoke trail and a throaty roar as the hallmarks of this popular propellant. Easy to track. Exciting to watch!

All Q-Jet™ 2-Motor Launch Packs come complete with FirstFire™ Micro Initiators and bright orange Parachute Recovery Wadding. All Q-Jet™ motors are U.S. mailable with no hazmat fee!

Steven P. ★★★★★

Finally getting consistent altitude readings with these Q-Jets; the lightweight composite casing really lets my rocket punch through the air cleanly.

Sophia ★★★★★

Flew these in my Estes rockets and they kicked off the pad way more aggressively than the old E9s ever did. The shorter burn time gave a snappier boost that I really enjoyed.

Andrew ★★★★★

Took these out for a Saturday launch and the two-motor pack means I got twice the fun without switching hardware. They're noticeably lighter than the E9s I've been using, which made the rocket climb feel snappier. Solid value for the flight time you get.
