D16-6 Q-Jet™ 2-pack 18mm model rocket motors. Includes initiators and wadding.

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 RCSs 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 initiator, which can be used with any launch controller. All Q-Jet motors are U.S. mailable with no hazmat fee!

    18mm blast-0ff

    Posted by Jim Readdy on 1st Dec 2018

    I love the smoke trail left by these engines. Starting with a heavy black smoke while thrust been is happening turning g into a white trail smoke until parachute ejection happens. The drawback being that the smoke is so thick the boost flame is covered up. The real plus to these engines for me is that I have plenty of under-powered 18mm engine mount rockets so the 16 Newton thrust is exact ally what I need for those rockets that have a little more weight than expected from the original kit specs.
