Here's some interesting pic's that show linkages that have perfectly symmetrical throws on the servos and surfaces. This is the Edge I mentioned in my previous post. The elevators end up opposite of what Seth posted on page 2 because the servo is up higher, the push rods are under the servo, and also these are Nelson horns...they are not pivoting on the hinge line. That's adds to the offset from 90 degrees. The ailerons have some offset too but not as much. I probably could have drilled that elevator horn bolt more straight but that can all be dialed out with the push rod length adjustment. I think I would have prefered that servo pocket a little higher.

The 2nd elevator is the Ultra RC 87" Yak (Extreme Flight with different covering). That really shouldn't have any offset but I probably glued the horn in not on the pivot...or the horn slots were not cut quite close enough. Again all dialed out in the push rod length.

The last is my Extreme Flight Extra aileron servo. This was the first I ever had that the servo arm tilted away from the hing line at center. It's all in where the servo pocket is located with respect to the horn.
