Quest Q-Jet™ B14-7T Blue Thunder 完整2馬達發射包 - Q6174

The composite propellant burns noticeably smoother than the black powder motors I’m used to, and the two-motor pack means I got a second flight right after the first. Ignition was instant and the launch rod fit was snug without any wobble.

Flying on a cool day, I lit the first motor and the Blue Thunder flame color was a vivid surprise—just like the NASA solid propellant description promised. The launches were crisp and high, with both motors in the pack performing flawlessly for a solid afternoon of flying.

Bought this for my son's first real rocket launch and the two-motor pack meant we got two flights instead of just one. The blue thunder propellant created an impressive, bright flame that was much more visible than the starter motors we'd used before.
