AeroTech G78-4G 29mm x 124mm 單次使用單馬達包 - 77404

The 29mm diameter fit my mid-power build perfectly and the boost was way punchier than the Estes motors I used to fly. Single-use means no casing to clean up afterward, which I appreciated at the field. Burn was smooth and consistent from ignition to ejection.

That composite propellant really puts out a punch — the G78 lit clean and my mid-power bird hit maybe 1,800 feet on the first try. Single-use means no casing to clean, which is honestly why I keep buying these for club days.

First launch on a G78 and the 29mm casing fit my mid-power build with zero slop. That composite grain lights fast and burns clean, no chuffing at all. Four flights in and the delay timing has been dead consistent.
