AeroTech RMS-38/600 모터 하드웨어 전체 세트 - 3860M

The aluminum case threads on smooth as butter, and the forward closure seals tight with zero blow-by on my last 600 reload. I've flown it three times now and cleanup is way easier than the single-use stuff I used to burn through.

The forward seal disc fit perfectly on the first try, no sanding or fussing needed. Threads on the closures are clean and the case feels solidly machined. Flew it twice this weekend and both reloads sealed without a hitch.

Snapped the aluminum case into my 38/600 reload and the fit was dead-on, no wobble at all. The forward closure threads smoothly every time, which matters when you're reloading at the pad between flights.
