If this is the case (I don't know) the prop and engine RPM should be linked, so an increase in one results in an increase in the other.... in which case Crumpp's description appears to be contradictory.
Can we all specify exactly when we are referring to prop rpm, when we a re referring to engine rpm, and when we are referring to both?
That would sure help me understand.
