REFLECTOR: Static RPM Question

[Al Gietzen]

Thanks.  I was aware of the effect on HP.  I was wondering if the decreased
air density made spinning the prop easier and if it would compensate.

Yes; the prop also spins easier; but the power decrease is directly
proportional to the density; whereas the prop drag goes as the cube root; or
some such; so the power loss wins.
