مخروط ذيل AeroTech RMS-75 75 مم وإغلاق خلفي - 75TAC

Fit my 01770 nozzle perfectly and the taper really cleaned up the back end of my minimum diameter build. Flights feel a touch slicker and it's held up fine after three reloads.

Slapped this on my minimum diameter build and picked up a few tenths on the altimeter compared to the flat stock closure. The taper blends right into the airframe, no lip at all. Just make sure you're running the large nozzle reloads or it won't seat.

Machined threads are buttery smooth and it seats flush against the forward closure every time, so no fiddling with alignment. Cut about 8% off my drag profile on the last L motor flight, and the anodizing still looks new after a few hot burns.
