and I have found that it doesn't make a difference, 'cause I am twisting to
acheive the desired pitch about 75% of the way out on the blade, anyway.

<DIV> I guess if you want to maintain a true helical pitch, if you are
reducing the pitch then you will need to add some pitch back towards the tips.
Higher pitch props have more twist along the blade than lower pitch props. So
if you depitch at one point towards the root, then you end up with a blade
that effectively has washout. Correct? That may be good for our purpose.</DIV>

size=2>Ideally you would twist the prop at several places to acheiv helical
pitch. In practice, this is entirely unnecessary. Twist once, as close to
the hub as practical, and that will work just fine. I see that Dave L added
more detail to the procedure.</FONT></SPAN></DIV>
