AeroTech HDK-24 RMS-29/40-120 休閒延遲套件（3入）- 43524

Ordered these for my G53-5FJ motors and the delay timing has been dead consistent across all three launches so far. The included O-rings and insulators saved me a trip to the parts bin, which is a nice touch. Ejection charges fired right at apogee every time.

The three delay elements and spacers dropped right into my G53-5FJ without any trimming, and the included O-rings and insulators meant I didn't have to dig through my parts box mid-build. Ejection timing came out consistent across all three flights.

I’ve bought delay kits before that never seemed to have all the parts, so finding the three delay elements with the insulators and O-rings actually included was a relief. The spacers let me fine-tune the delay without any guesswork, and everything seated snugly on the G53-5FJ motor.
