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 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!

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 U. ★★★★★

First time using composite motors and the white lightning propellant gives a much louder, punchier burn than the old black powder ones. The C18-4W delay was right on for my lightweight build, and having two motors in the pack meant I could fly twice in one afternoon.

Harper ★★★★★

Bought these to finally try composite motors after years of black powder, and the C18-4W packs a noticeable punch for an 18mm. The white lightning propellant gives off a bright, clean flame and the delay felt right on for my lighter builds. Two motors in one pack made it easy to fly the same rocket

Timothy Q. ★★★★★

Got these for my son’s first high-powered launch and the two-motor pack meant we could fly back-to-back without a dull moment. The ejection charge fired right on cue both times, and the smoke trail was a nice touch for tracking.
