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 or phenolic nozzle and one of RCS's exclusive Black Max™, White Lightning™ or Blue Thunder™ aerospace grade composite propellant formulations, which produce up to 2-1/2 times 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, dense 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!

Samuel H. ★★★★★

First time trying composite propellant in 18mm and the blue thunder burn is noticeably punchier than the black powder motors I'm used to. The three-second delay popped the chute right at apogee on my scratch-built bird. Two motors per pack feels a little stingy, but the performance is worth it.

Victoria R. ★★★★★

Grabbed these for my Estes-style 18mm builds and the composite propellant really does burn cleaner than the old black powder motors I used to fly. The B14-3T kick off the pad is snappy, and the two-motor pack plus launch gear made for a solid afternoon.

Evelyn Z. ★★★★★

The composite propellant burns noticeably cleaner than the old black powder motors I used years ago, and having two Q-Jets in the pack meant I could test-fly twice without a trip to the hobby shop. The launch pack gave me everything needed for a solid afternoon at the field.
