When does a shaved prop loose it's efficiency on speed?
Yeah I see that you are saying. Good point!
I was checking out a site earlier on carbon props and they have smaller sizes that I think may work just like they are. I am not sure yet so going to order a few and see how it goes.
I would feel much more comfortable with a prop designed for that size for optimal performance rather than shaving down some. I mean don't get me wrong it does still work but just seems like it would be much better with a prop made at that size that works best for your engine pipe set up.
