I like the idea of a highly polished spinner on my plane. The original spinner was plastic and 2" in dia. but I may go with the 2 1/4" size. Have you ever had any trouble with the Prospin spinners vibrating loose?? Thanks so much for the help.

The aluminum spinners I have used are Great Planes and Tru-Turn. They were satin finish, not polished, so I didn't mention them. I've never had one come loose.
I did destroy two GP 3 inch spinners on my PT- 60:
Nose low landing, spinner split from the prop slot to the retaining bolt
Botched takeoff, hit high weeds, prop broke, and it bent the spinner
I switched to a spinner nut after that. My trainer finally died but the spinner nut lives on and will probably go on my Four Star 60.
