Perfect for small groups and family rocket outings!

Quest Q-Jets are the world's most advanced 18mm model rocket motors. Q-Jet™ high performance, composite propellant model rocket motors use the same family of solid propellant as NASA’s Space Shuttle Boosters, military missiles, sounding rockets, and NASA’s future SLS moon rocket. 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-Jet™ rocket motors deliver faster lift-offs, visible exhaust plume, denser dark tracking smoke & increased reliability at lift-off.

This Q-Jet™ 12-Motor Value Pack comes complete with 14 FirstFire™ Micro Initiators and bright orange Parachute Recovery Wadding. All Q-Jet™ motors are U.S.mailable with no hazmat fee!

Jacob X. ★★★★★

These composite motors light way faster than the old black powder ones I used to mess with, and every single one in the 12-pack fired clean with no misfires. The 4-second delay is spot on for my lighter rockets, so they pop right at apogee.

Matthew ★★★★★

Bought the 12-pack for a weekend launch with my nephews and every single motor lit clean on the first try. The 4-second delay is just right for smaller fields, so we got the chutes out without losing anything in the trees. Twelve in a box means we actually got to fly all afternoon instead of rationi

Steven N. ★★★★★

The composite propellant really makes a difference — way more consistent thrust than the old black powder motors I used to fly. Twelve in the pack meant the whole family got multiple launches without me rationing them. Cleaner burn too, hardly any residue on the casing afterward.
