Default Do 28 Skyservant

I tried to get a response to this at the Aerodynamics forum but I guess it wasn't challenging enough to elicit a reply. Anyway here is my dilemma:
I am currently building a Do 28 D Skyservant with a stabilator. I have a question concerning the loads imposed on the controling servo. I've been told that I will need a servo with twice the normal torque due to the load imposed by the relative wind on the stabilator when actuated. In my opinion I do not see a need for a stronger servo. I'm guessing that the load imposed on the leading edge of a deflected stabilator will be offset by the load imposed on the trailing edge. Am I correct?
As a point of information, the pivot and horn are placed at the 50% chord position.
