my saito .72 calls for a 13x6 prop. I would like to change to an 11x7 3 blade (due to clearance problems). Does anybody know where to find one? APC doesn't appear to make one.

Also tower doesn't carry a 2 1/4" 3 blade spinner. Anybody know where I can find one?

take a look here>

Scroll down on that page and they show a 2" and a 2 1/2" spinner but no 2 1/4".

Here is an APC, but smaller>

Hope this helps
