AeroTech RMS-54 54mm EFC 馬達封閉轉接器 - EFC54-2

Was a bit nervous about a clearance item, but the timer module fired exactly on schedule during my first flight with it. The attachment to the forward end of the 54mm case was rock solid, no wobble at all.

I was pleasantly surprised by how snug the timer-based deployment module fits onto the motor's forward end—no wiggling at all. Used it with my 54mm reloadable casing for a clean ejection at apogee, and the whole setup worked perfectly on the first try.

Finally got this to work with my 54mm hardware and the timer-based deployment feels way more reliable than the old altimeter setup I was using. The forward-mount design makes installation straightforward.
