Quest C18-8W Q-Jet White Lightning -- C Model Rocket Engine -- #6127

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 nearly double the specific impulse (or "Isp", a propellant efficiency rating) of conventional ...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 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.
