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 Pro54-5G case. Reusable hardware you buy once, plus the single-use reload.

Reusable hardware to own

Single-use reload to buy

1997K650-21A reload cartridge

Single-use cartridge: preassembled grains, liner, nozzle, and forward closure — loads as one piece, and ejection charge

  • 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.
