Listers,
Hartzell recommends a minimum .1" clearance around the prop blade for the spinner. 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!
