AeroTech RMS-54 54mm 426 N-Sec 알루미늄 모터 케이스 - 5442C

The threads are machined clean and the case screws together without any binding, which is exactly what I want before a flight. Snagged it on clearance for a 54/426 reload and the anodizing already looks like it'll hold up to a few hard landings.

The anodized finish is holding up well after three launches, and the 426 N-Sec rating gives me confidence for aggressive reloads. It’s a solid, straightforward casing that fits the 54/426 hardware perfectly.

Finally found a 54mm case that doesn’t feel flimsy, and the aluminum threading is butter-smooth when assembling. Worked flawlessly with my first 426 N-Sec reload, no leaks at all.
