Robo, yes, but if you have different tension in the upper and lower cable you are not really changing the throw. You are just allowing slop in the looser cable which gives a false since of changing throw. It's kind of a technical point. And what you say probably works. But from a purely technical point and the "I know I did it" point of view, I think it's a compromise.

I have given this problem a geat deal of thought and come to the conclusion that a single servo, split elevator, pull-pull is not the best system for the simple point that the hinge line on both sides must be exactly on plane for the throws to be identical. When I re-hinged, it threw the two sides off.
