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 RMS-54/426 case. Reusable hardware you buy once, plus the single-use reload.

Single-use: grains, liner, nozzle, o-rings, delay element, igniter, and ejection charge

  • A dab of high-temperature o-ring grease is needed on assembly (it comes with most hardware sets).

Cases that fly it

Its own case is the simplest; a longer case flies it too, with the adapter and spacers.
