Quest Motor 18mm Composite Model Rocket Motors Q-Jet D20-4W(2pk) QST 6130 <Required to Pay for Parcel Select Shipping>
The Q-Jets are the world's most advanced 18mm model rocket motors. They utilize a patent pending high-strength polymer case and bulkhead, ceramic nozzle and our exclusive Black Max™ or 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-Jets generate a highly-visible exhaust plume and delay smoke trail. All Q-Jets ship with a FirstFire Micro™ 2-lead initiator, which can be used with any launch controller. All Q-Jet motors are U.S. mailable with no hazmat fee!
