Quest Q-Jet B4-4FJ Black Max Rocket Motors Value 12-Pack - Q6314

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 propellants as NASAs Space Shuttle Boosters, military missiles, sounding rockets, and NASAs 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.
