علبة محرك ألومنيوم AeroTech RMS-75 75mm 6400 N-Sec - 7564C

The fit and finish on this casing is spot on, threads are smooth and it reassembled cleanly after the first flight. Works flawlessly with the 6400 reloads I had on hand, just make sure you’re getting the high power kits, not the mid power ones.

Machined threads are buttery smooth, and the case fits every 75/6400 reload I've tried without any forcing. Took it apart after a smoky flight and it cleaned up in minutes, no stuck residue anywhere. Solidly built piece of hardware.

The anodized finish on this 75mm case feels rock-solid, and it fits the RMS-75/6400 reloads perfectly with no slop. The threads are clean and the assembly was straightforward, exactly what I needed for my L2 project.
