AeroTech G77-7R 29mm x 124mm 一次性1馬達包 - 77707

That launch lug seated the motor perfectly, and the composite propellant lit off with a clean, hard thrust that sent my rocket straight and true. The 7-second delay fired right at apogee, a textbook flight from start to finish.

Watching that G77-7R tear through the sky with zero hesitation made me feel like I was launching something off a real launchpad. The composite propellant burned clean and smooth, and the single-use pack meant zero cleanup hassle afterward. Already ordered two more packs for my next launch day.

The composite propellant gave my rocket a much more stable and powerful boost than the black powder motors I've used before, and the 29mm size fit my mid-power build perfectly. It burned with a satisfying blue-white flame and left very little residue to clean up afterward.
