Quest Q-Jet™ C18-6W White Lightning 火箭引擎 超值25入裝 - Q6436

The composite propellant burns way more consistently than the old black powder motors I used as a kid, and the six-second delay gives a nice gentle coast before the chute pops. Thirty-eight bucks for 25 of these is a steal for a whole afternoon of launches with the family.

These little motors fit perfectly in our family’s starter rockets, and the 25-pack means we didn’t have to ration flights on a sunny afternoon. The composite propellant lit cleanly every time, no duds in the whole box, which made the day feel worth every penny.

The composite propellant burns so much smoother than the old black powder engines, and having 25 in one pack means we didn't run out halfway through the afternoon. My son and I got through eight launches before the wind picked up, and every single one lit on the first try.
