I found out that Whirlwind now has 12" spinners for the UL350 engines, which I am installing on my RV-12. This goes with their GA-350-3B and -2B props. After discussion with them, I learned that the -2B is intended for STOL applications, but the 3B is recommended for more streamlined airframes.
I'm buying the -3B with the 12" spinner. Sure looks nice.

- Several others that are now just great memories for me.
