Keep in mind that a MaxProp does not really have a "pitch" but rather a blade angle. Its
pitch is different at the blade root than at the tip due to lack of blade twist. The
pitch referenced is an average based on blade angle. It does not necessarily correlate precisely with a fixed prop pitch.
Another thumbs up for Gerr's Handbook. Clears up some common misconceptions, some of which have been repeated in this thread...
