OK.. so now tell me what the effective torque applied to the surface is with the pushrod at this distance from center, coupled to a control horn at its distance from the hinge line (it's lever point).

My guess is off the top of my head that you'll find this servo delivering over 120 oz" of effective leverage to the surface. There is a fair amount of mechanical advantage in the Bobcat elevator linkage geometry.

I don't know the exact distance of the control horn off the hingeline, so someone else will have to do the actual math.
