They utilize a patent pending high-strength polymer case and bulkhead, polymer nozzle and RCSs exclusive Redline aerospace grade composite propellant formulation, which produces a visible scarlet flame. Redline motors burning rate lies midway between that of White Lightning and Blue Thunder. Photos dont do justice to the laser-beam intensity and color of Redline. you have to see it to appreciate it!\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThis AeroTech motor pack comes with 2 rocket motors and 2 FirstFire Jr. Initiators. \u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eCertified by the Tripoli Rocketry Association (TRA), the National Association of Rocketry (NAR) and the Canadian Association of Rocketry (CAR).\u003c\/p\u003e\u003cul\u003e\u003cli\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv\u003e\u003cdiv\u003e\u003cdiv\u003e\u003cdiv\u003e\n\u003cp\u003eMotor Diameter 1.125 inches (29mm)\u003c\/p\u003e\n\u003cp\u003eCasing Length 3.28 inches (83mm)\u003c\/p\u003e\n\u003cp\u003eTotal Impulse 49.6 N-sec\u003c\/p\u003e\n\u003cp\u003eAverage Thrust 24.4 newtons\u003c\/p\u003e\n\u003cp\u003ePeak Thrust 37.7 N-sec\u003c\/p\u003e\n\u003cp\u003eThrust Duration 2.03 seconds\u003c\/p\u003e\n\u003cp\u003eDelay Time 4 seconds\u003c\/p\u003e\n\u003cp\u003ePropellant Weight 28.4 grams\u003c\/p\u003e\n\u003cp\u003eMotor Weight 79 grams\u003c\/p\u003e\n\u003cp\u003eMaximum Liftoff Weight Due to the variables involved, AeroTechQuest currently does not list or post recommended maximum lift-off weights for their mid-power and high-power rocket motors.
