I knew that the rotation of a "tractor" motor in a "pusher" orientation is opposite direction of a "tractor" motor in "tractor" orientation. I had hoped I had said that correctly in my first post. Guess I didn't... Sorry.

The way I see it, there are two kind of engine/prop "pusher" configurations possible.

1. A "tractor" motor mounted backwards in a pusher orientation with "pusher" prop.

2. A "pusher" motor (spinning in opposite direction of a "tractor" motor), with a "tractor" prop.


Either configuration, the lettering on the prop must be facing the front of the plane.


That being said, I'm thinking more from a pure aerodynamic standpoint. Say you have a 10-6 prop on both of the above setups. Would the shape of the prop bladed differ? Like the rate of twist, thickness of prop blades, etc.

I hope that makes more sense this way...
