Sir if you are looking aft a standard prop turn counter clockwise. If you flip the prop over and switch the leads so the motor turns clockwise that same prop will pull the plane ...
No, it won't. "Flipping the prop over" doesn't change it to a "Pusher" style. It only makes the airfoil run upside down - the pitch is still in the same direction. Try it.
If you get a "pusher" prop and run it in the opposite (from the usual) direction, it will indeed fly the model in the same direction. Unfortunately, the selection of Pusher props is quite limited, compared to Tractor props and the effect on line tension is really not all that dramatic.
