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-54/2560 case. Reusable hardware you buy once, plus the single-use reload.

- 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 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.
