I'm in the market for 3 aluminum spinners for my planes. Although I'd love to pick up some Tru-Turn units they're prohibitively expensive. I've got a Kangke unit on my Avistar. It was relatively inexpensive, but it's chipped and scarred in a couple of places from when I had too much oil on my electric starter and it slipped off the spinner resulting in metal to metal contact. Does anyone know if the Cermark spinners are like that? And will an APC 11x6 prop fit into a Cermark 2 and 1/4 inch, 2 and 1/2 inch, or 2 and 3/4 inch spinner without any trimming?

Thanks!
