The standard aircraft engine turns ccw when looking at it from the prop end. Both the tractor prop and the pusher prop turn in the ccw direction. The blades are mounted to pull the air(tractor) or push the air(pusher). I hope that explains it. Dennis
I was distracted when I posted my last message. I should have said both props spin CCW, however the L.E and T.E are opposite one another in a pusher v. puller comparison. sorry.
