And another thing, man I'm grouchy this morning. A servo tab creates feel, or what is called the Stick Force per G gradient. Maybe that is what you were trying to say but it was unclear.

Stabilators have to be aerodynamically balanced around the aerodynamic center of the surface. If they weren't not even DE727UPS could push or pull the yoke on a cherokee. Since it's balanced it has little forcing it back to the slipstream position. The servo tab is essentially a small elevator on the trailing edge of the stabilator generating a centering force. It also doubles as a trim tab but that's another story.
