"Big thrust in a 24mm reload"
duanenorris (Richmond, KY)
As advertised, the Blue Thunder propellant delivers on thrust. I launched the Aerotech Initiator on this motor and was not disappointed. It leaped off the pad quicker than the F24W motor, but didn't give the same bright flame. I got a bit more altitude with this motor as well (635ft). I like the sound and flame of White lightning, but this is still a great motor. I would buy again.

"Great on thrust, not so impressive on aesthetics."
This is a good motor for a first flight on a lightweight 29mm rocket like my Estes Argent. It gives a nice jump off the pad, but it keeps the rocket low enough (5-600 ft.) That even with cloud cover or wind, recovery is easy. The only bad thing about this motor, is that in such a small size the bright blue flame is nonexistent, and there is little smoke, so this motor lacks in the ooh, ahh category.


  • Damaged or defective reloads should be returned to Aerotech.
  • Read and follow the safety codes of the National Association of Rocketry (NAR) and the Tripoli Rocketry Association and comply with all federal, state and local laws in all activities with hobby rockets.
