غلاف محرك ألومنيوم AeroTech RMS-75 75mm 2560 نيوتن/ثانية - 7525C

Finally got to fly the 75mm case with a J350 reload and the sealing rings held perfectly with no leaks. The anodized finish on the aluminum seems like it'll hold up well to repeated high-power flights.

Swapped my old motor case for this 7525C and the aluminum feels rock solid in hand, nice thick walls. The threads on the forward closure mate cleanly with my RMS-75 hardware, no binding at all. Ready to load a 2560 reload kit for the next launch day.

Machined the threads for the forward closure today and they engaged cleanly, no cross-threading hassle. Case took the 2560 reload without any fit issues. This one’s going to last me a good while.
