Fred Weick's area of study and expertise, before the Ercoupe, was in propellers. He designed the rudder-peddle-less Ercoupe with the following design considerations because you can't hold right rudder on climbout to counter P factor. (1) Engine mount points the thrust of the crankshaft and prop to the right and down slightly. (2) The twin vertical fins are wider than the prop and thus out of the prop slipstream which wraps aroung the fuselage and strikes the side of the vertical fin on single vertical fin airplanes. The accelerated, spiraling, wind from the prop goes right between the two verticle fins which are in undisturbed air on the twin fin Ercoupe.
I've been told, or read, that these two things designed in by Fred eliminate the need for us to have to hold right rudder on climbout, made it possible to leave out the pedals.
