Beyond the case, every reload below needs the 75 mm forward closure, the 75 mm aft closure, plus the 75 mm forward seal disc— reusable, and shared across every 75 mm case in the AeroTech RMS line.

Cross-brand crossload (8 Cesaroni Pro reloads)

Cesaroni supplies the o-rings to fly its Pro75/98 reloads in RMS hardware — but AeroTech recommends against it: an RMS case needs a forward seal disc and o-ring the Cesaroni reload doesn’t include (forward-end overheating risk), and AeroTech won’t warranty the combination.

A cross-brand motor must be certified in the hardware it’s flown in — treat this as a starting point and build to the reload’s printed instructions.
