Hi Jim,
The rudders move out 20º and in 3º.
Accordingly, the effective area of the rudder in flight is 65% of the
total area.
If the forward speed of an Ercoupe is reduced to minimum speed before
touchdown (gradual increase in elevator action to maintain about a foot
off the runway as the plane slows), at touchhdown and afterward the
rudders have little effect.
The differential action of the ailerons do the work.
Regards,
William R. Bayne

Simple question from a neophyte:
It seems obvious that the rudders on an Ercoupe can only move outward,
not inward, because of the elevator being in the way. Am I missing
something?
If not, then my hypothetical description of an Ercoupe crabbed landing
contained an error. Only one rudder would be pushed sideways, not both,
when the plane pivots.
Regards to all,
Jim
