See, the people at RCV are engineers. This is why I doubt such an odd curve is real.

OK, Greg.

Let's now see if Juice can produce RPM numbers for fractional pitches, between 11" and 13" for that 18" diameter prop...

The numbers don't lie and the fact that the RCV people are engineers, does not immunize them from creating bumpy torque curves...
It is not an engineering error.

What does seem to be extreme in that drop, that not only is it a drop in torque, but that even the rise in RPM did not prevent the HP from falling also.
Actual dips in the HP curve are rather rare (except after peak HP), while torque dips are all over the place.

If we could only ask RCV about it... We'll see what they say.
