This 25pack of D16-4FJ Black Maxx Rocket motors is 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 25-Motor Launch Pack comes complete with 29 FirstFire Micro Initiators and bright orange Parachute Recovery Wadding. All Q-Jet motors are U.S. mailable through the United States Post Office (5 - 21 business day ground service with no hazmat fee!)

For faster service, we offer UPS 2 - 5 day UPS Hazmat service with a $37.00 UPS hazmat fee per shipment). This fee is imposed by UPS and passed on to the customer.
