Quest Motor 18mm Composite Model Rocket Motors Q-Jet B6-4W(24pk) QST 6418 <Required to Pay for Ground Advantage or UPS Ground Shipping>
Perfect for classroom programs, large groups and camp activities!
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™ 25-Motor Value Pack comes complete with 29 FirstFire™ Micro Initiators and bright orange Parachute Recovery Wadding. All Q-Jet™ motors are U.S. mailable with no hazmat fee!
