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!

Customer Reviews (5.0 / 5 · 4 reviews)

Miles ★★★★★

The motors lit instantly and the weight difference from the old BP ones was noticeable right away—my rocket climbed faster than ever. Even with two launches in the pack, I’ve got enough for a solid afternoon at the field.

David ★★★★★

The two-motor launch pack gave me just the right amount of power for my first high-altitude flight, and the 68% weight reduction made a noticeable difference in stability off the rod.

Chloe B. ★★★★★

I was surprised at how much lighter these are compared to the old E9 motors I used to fly—really noticed the difference in stability. The two-motor pack gave me two perfect launches right out of the box, and the burn time felt just right for my small rocket.
