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 Pro38-4G case. Reusable hardware you buy once, plus the single-use reload.

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.
- This reload is out of production. That is not the same as decertified — it stays flyable until stocks run out — but it may be hard to find.
- 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.
