Quest Q-Jet™ B4-4FJ Black Max Rocket Motors Value 25-Pack - Q6414

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 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™ 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!
