محول إغلاق المحرك EFC AeroTech RMS-29 و RMS-29/40-120 29 مم - EFC29-4

The adapter threads onto the forward end of my 29/40-120 case without any slop, and the timer fired the ejection charge right on cue at apogee. Nice to finally ditch the motor delay drilling and just dial in the backup. Grabbed a spare before they vanish.

Wasn't sure a timer-based module would fit my older 29/40-120 hardware, but it threads right on with no wobble. Deployment timing was dead consistent across four flights, which saved me from guessing on ejection charges. Wish I'd grabbed a spare before they're gone.

The screw-on fit onto my RMS-29 casing is rock solid with zero wobble, and the timer adjustment clicks feel precise enough to trust on a high flight. I grabbed it on clearance knowing it was a gamble, but the adapter threads matched perfectly and it deployed right on schedule.
