Yep, and I suppose this is why all my carved "pitch" blocks appear to
have a higher RATE of angular change nearer the prop hub,
rate "slowing" at other end. Many modeling primers show a metal screw
to describe "our" pitch, but none of my correctly carved pitch blocks
resemble such a constant rate of angular change. Anyhow, on block I
scooted my F1L blades 1/4" outboard of its "correct" radius, but will
mount it at nominal 28".
