Product Description

Quest Motor 18mm Composite Model Rocket Motors Q-Jet A3-4FJ(2pk)  QST 6108 <Requires Parcel Select Shipping> (QST 6108)

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™
