Quest Motor 18mm Composite Model Rocket Motors Q-Jet C12-4(2pk) <Requires Parcel Select Shipping> (QST 6108)

The Q-Jets are the world's most advanced 18mm model rocket motors! They utilize our 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-Jets generate a highly-visible exhaust plume and delay smoke trail. All Q-Jets ship with a FirstFire Micro™ 2-lead igniter.
