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 Pro29-4G 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, and ejection charge

- Sparky (metal-loaded) propellant: many ranges restrict these for fire risk. Check your field's rules before flying.
- 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.
