It seems to be what I interpret as a cam in the cable linkage that does the trick? The same principle makes the DOWN motion in the ailerons different from the UP motion, I believe.
I first learned of this by studying a home-built VARIEZE.

I don't understand how this happens since they seem to be linked together. Since the cables don't stretch and I don't see any fancy mechanism, how does any one of them move more one way than the other?

Interesting little tid-bit, I thought.

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
