Notes

A tractor prop pulls from the front; a pusher pushes from the back. The FAA notes pusher propellers are subject to more damage than tractors because of ground clearance (FAA Powerplant Handbook).
Propwash over a tractor's tail increases rudder effectiveness (FAA PHAK ch.6), which pushers lose; McCombs notes tractor vs pusher mounting shifts the required fin size (Model Aviation). APC pusher props carry a 'P' suffix (APC).
The file is a reference example built by Xem Studio from the numbers above. Sizes the sources do not fix are illustrative; scale the example to your own vehicle.
