Yahoo! I really like the looks of the non-blended airfoil blades. They just have a more traditio nal=2C mean and manly look=2C IMHO. The 72" dia also has those fatter paddl es which looks cool too. > > Just two weeks from initial engine mounting to prop installation. The FWF controls and wiring are done too.

I did that exactly, but the prop would still bang on the spinner at full pitch. I had to hog out to .25" to keep the clearance at .1" at full pitch. It looked stupid having such a large gap in one area only so I evened it up to .25" all the way around. But now it kind of looks like I made the holes too big. I just can't recall seeing other installations to know if my .25" is "too much". Anyone have any pics or thoughts on the clearance using late-model Van's CS spinner and a Hartzell, particularly the 72" paddle blades I've got? Thanks!

Then I, cut'n fit, cut'n fit, cut'n fit, until I had what appeared to be adequate clearance between the spinner and prop blade. I didn't know about the 1" requirement - sounds like a lot. Hmm...now I wonder if I have enough clearance. Don Owens Listers, Hartzell recommends a minimum .1" clearance around the prop blade for the spinner.
