Re: 6 blade generator mounted fan on a '32
I'd think a larger blade with less blades would be better. Sometimes less is more.
To some, 2 blades push more air then 6 blades. RPMs considered. More blades, more air to impede. Just a thought. 4 blades should be plenty to move air. Planes have used 2 blades for ever. Granted later 4 blades, and the new stuff is like almost turbine.
