Muster is a shopping aid, not an assembly guide. Build only to the reload's printed instructions — always the authority — and confirm every part with the manufacturer before you buy or fly.
What you need to fly it
The simplest build — in its own Pro98-6G case. Reusable hardware you buy once, plus the single-use reload.

Single-use reload to buy
Single-use cartridge: preassembled grains, liner, nozzle, and forward closure — loads as one piece (no ejection charge)

- This reload is plugged — it carries no ejection charge and must be flown with electronic deployment (a timer or altimeter) and a plugged forward closure.
- A little high-temperature grease on the closure threads and o-rings helps on assembly.
Cases that fly it
Its own case is the simplest; a longer case flies it too, with the adapter and spacers.
Also flies cross-brand (crossload)
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.
