Just for the heck of it..... in comparison...

On a twin engine BOAT , the prop tips rotate tips outward at the top
of the arcs for best handling and fuel econmy..

The boat handles like a pig if this is set up in backwards, and the
fuel economy plummits..

P-factor and rotation is always, by convention, based on the
top blade moving downward.


I can't think of a situation where the top blade would move any direction
but down. ;-)

The most common rotation pattern in modern twins is for the top blade(s) to
rotate towards the fuselage.
