Includes initiators and wadding.\u003c\/p\u003e\n\u003cp\u003eThe Q-Jets are the world's most advanced 24mm model rocket motors. 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 over 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.\u003c\/p\u003e\n\u003cp\u003eAll Q-Jet motors are U.S. mailable with no hazmat fee!\u003c\/p\u003e\n\u003cp\u003eSpecifications:\u003c\/p\u003e\n\u003cp\u003eMotor Diameter: 0.938\" (24mm) Casing Length: 2.75\" (70mm) Total Impulse: 19.3 N-sec Burn Time: 0.90 seconds Average Thrust: 22 newtons Delay Time: 4 seconds Propellant Weight: 12.0 grams Motor Weight: 37.5 grams Maximum Liftoff Weight: 397 grams susceptible to thermal cycling like black powder motors.
