How to Assemble an AeroTech RMS Reload Without Guessing
An orientation to AeroTech RMS cases, delay drilling, o-rings, liners, and grain order — written to sit next to the instruction card.
By Burn Wire
AeroTech reloadable motor systems (RMS) are how a lot of fliers stop lighting a new single-use case every flight. The hardware is simple. The mistakes are simple too: the wrong o-ring, a delay installed backward, no liner, grease in the wrong place, or a Cesaroni part that “looked the same on the table.”
This article is orientation. The reload kit’s instruction card, the case dimensions, and the delay drill chart that came with that kit are the authority. If this text and the card disagree, the card wins. Confirm the motor on ThrustCurve and in the motor-code guide before you buy.
If you are picking an L1 motor rather than assembling one, start with best motors for L1.
