That should have been:
pitch in inches X rpm = inches per minute X 60 minutes

I am not sure why this never occurred to me when I was flying KR, maybe the
cost. They are expensive, but do solve the issue of the limit on the length of
the prop for the RPM necessary to achieve maximum power out of an auto
conversion engine. I am flying a 3 blade ground adjustable prop from
4 matches
