I wonder if you could include a 70Knot and 106 Knot curve on both
graphs.  70 Knots is close to what I lift off for initial climbout of the
field. 106 Knots is my best rate of climb speed.

   I presume you will now do the same for the LAEV prop

Ed:

Here are plots from a run on your prop. Here is the color code for the
curves:
Static - red
60 knots - green
130 knots - turquoise
150 knots - blue
160 knots - pink
170 knots - black

You can draw a curve of HP vs. RPM on the HP plot, I drew one on there
for reference but it's arbitrary.
It looks like your pitch is not really 72 inches but more like 68
inches.

Ed, I think I had the wrong formula to calculate pitch, it looks like
your pitch is around 72 but varies quite a bit across the blade.
