Quest Q-Jets are the world's most advanced 18mm model rocket 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 Black Max™ 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™ rocket motors deliver faster lift-offs, visible exhaust plume, denser dark tracking smoke & increased reliability at lift-off.

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

Kevin ★★★★★

Finally got to launch one of these and the ignition was instant with no misfires, a huge relief after struggling with cheap motors. The two-motor pack gives me a solid backup for a second flight while the clean composite burn leaves practically no residue on the launch pad.

Evelyn ★★★★★

The composite propellant burns way cleaner than the old black powder motors I’m used to, and the two-motor pack means I can launch twice without digging in my pocket again. Even on a breezy afternoon, the ejection charge popped the chute right at apogee—no drift, no fuss.

Ava ★★★★★

I was honestly surprised how much higher these Q-Jet motors took my rockets compared to the standard ones I've used before. The composite propellant feels like real quality.
