OK,
Changed out the servos. Didnt help.
Went from Z Bend connections to carbon fiber pushrods with threaded clevis couplers on both ends to eliminate all play whatsoever, mechanically adjusted everything out to level with no trim or subtrim. I even moved one of my control horns so that they are TOTALLY exactly in the same locations on the control surfaces.

Still have something really weird going on, no matter what the endpoint is set at on high or low rate, at 90% up elevator input on the stick the right elevator is full up,,,, the left elevator is at about 75-80% of its endpoint. The last 10% of up elevator gets the left elevator up the rest of the way so that with full up on the stick the elevators match. In a nutshell the 2 halves move at different ratios but eventually get to the same endpoint.

Geist,
Is this something I just have to live with unless I buy digital servos? Is this is typical for all planes with dual servos and ailevator function??
If I go back to a Y harness will that do it? I dont use the ailevator function for anything except standard setup of these two elevator servos.

Everyone Thanks a million for the input.
