Folks, I read several of the threads concerning wood props and the Sensenichs for the C-85. I could not find any reference that said the prop for a flanged shaft engine is different from the taper shaft. I have the opportunity to buy a 72GK-44 that came off a flanged shaft engine. Will this prop work on a tapered shaft engine? I can't remember what the back side of mine looks like when I last took it off my A-65. I am building a C-85-8 and can't run the same prop as the one I have on the A-65. What do you all think?
