Good job, Downunder....but you gotta admit....the prop pitch thing does sound good.
I've always subscribed to the idea to break-in the engine on the same prop that your going
to run....I generally run smaller, higher pitched props that allow maximum RPM's from the
engine, so overheating has never been a problem, on the ground or in the air.
I don't own a prop under an 6" pitch anyway.
