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!

Emma ★★★★★

The composite propellant burns noticeably smoother than the old black powder motors I’ve used, and the two-pack means I got twice the launches out of the box. My first flight went up clean and straight with a satisfying crack at ignition.

Zoe ★★★★★

The two-motor pack is perfect for getting started with high-performance launches. I was really impressed by the consistent, powerful thrust from the composite propellant—way smoother than the old black powder motors I used as a kid. Feels good knowing it uses the same kind of fuel tech as the Shuttl

Natalie A. ★★★★★

The Blue Thunder propellant gives off a nice visible flame and a much punchier boost than the old black powder motors I used to fly. Both motors in the pack lit cleanly on the first try with the included igniters, no misfires at all. My Estes rockets finally fly the way they should on 18mm composite
