Quest Motor 18mm Composite Model Rocket Motors Bulk Pack Q-Jet A3-4FJ,B4-4FJ,C12-6FJ,D16-6FJ(12pk) QST 6312 <Required to Pay for Ground Advantage or UPS Ground Shipping>
Three each of the most popular Q-Jet composite propellant model rocket motors! Perfect for small groups and family rocket outings!
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™ 12-Motor Value Pack comes complete with 14 FirstFire™ Micro Initiators and Parachute Recovery Wadding. All Q-Jet™ motors are US mailable with no hazmat fee!
Certified by the Tripoli Rocketry Association (TRA), the National Association of Rocketry (NAR) and the Canadian Association of Rocketry (CAR).
