But the question is, what would that Glasair II do with other props?  My
friend Felix has a Glasair with an O - 320 (160 HP, 40 LESS than the IO -
360) and a fixed wood prop and can go 245 at SL.    The Glasair is a fast
plane to begin with so we need comparative data to make a judgement on prop
performance.

I do plan to revisit my IVO prop again when I try some blade root fairings.
I think David Atkins re-profiled the blade leading edge, not the root.
