Quest's Q-Jet 18mm model rocket motors use an aerospace-grade composite propellant. Q-Jets generate a highly-visible exhaust plume and delay smoke trail. All Q-Jets ship with FirstFire Micro two-lead igniters which can be used with any launch controller.

This is a package of two A3-6 Q-Jet motors with two igniters.

  • Designation: A3 Q-Jet
  • Diameter: 18.0000 mm
  • Length: 80.0000 mm
  • Propellant Weight: 2.1000 g
  • Total Weight: 17.9000 g
  • Average Thrust: 2.9762 N
  • Peak Thrust: 7.1100 N
  • Total Impulse: 2.5000 Ns
  • Class: 100% A

Note: We are required to ship orders containing motors by "surface mail" (Parcel Select). So, please plan on your order taking longer than normal to ship and arrive if it contains motors.

Model rocket motors cannot be shipped outside the US.

While designed to be compatible with rockets using Estes 18-mm engines (and Quest's earlier 18-mm motors), the first production run of the Quest Q-Jet motors are slightly too large in diameter for some rockets. You may need to peel off the Q-Jet motor's label and, possibly, modify your rocket's motor mount to use one of these motors. We expect Quest to address the issue when the next batch of Q-Jet motors is produced.
