The anti-servo tab on the Piper stabilators is not to "de-power" the stabilator, but to provide control feel for the pilot, and give the stabilator a tendency to move to the trimmed position. When the pilot moves the controls, the anti-servo tab provides the resistance the pilot needs. A larger anti-servo tab would give the airplane a heavier control feel. Balancing the size of the tab, the amount of deflection is makes with respect to the amount of deflection of the stabilator is what gives you the control feel you need to safely and effectively control the aircraft.

To follow your line of reasoning, if the stabilator tab linkage broke, allowing the tab to float free, the result as experienced by the pilot would be reduced control feel, resulting in "twitchy" pitch response, yes???

HI ANDREW, stabilators can be set up to groove nicely. You can cut grass with a well adjusted 120 mph C/L combat plane. You will probably find that anywhere from 1/8"+ or -, up to 1/4"+ or - of throw will do the trick. I have used them with no aerodynamic counterbalance, but I think hinging at 25% chord is considered "full scale".

Yes, reduced or no feel, along with a very-much reduced centering tendency, it any remained at all.
