Rudders and crosswinds

I've only flown Ercoupe without rudder pedals, but it's clear to me that the presence of separate rudder controls would make no difference in the geometry of how the plane lands. Everyone knows that the rudders on an Ercoupe are small and have limited effectiveness. I suppose you can use them in a mild crosswind to land straight on the centerline, but it wouldn't take much of a crosswind to exceed that. Since it's the exact same airplane with or without rudder pedals, landing in a crab should work either way. I do not believe there is a published maximum crosswind component anywhere out there, at least from the manufacturer. I've alway said the amount of crosswind you can land an Ercoupe in is directly proportional to the size of your cajones....
