Keep in mind that aerodynamically balancing the surface won't do anything much to the movements you will experience in a model unless you have poor connections or have inadequate servos. The surfaces of models are held rigidly by design. There won't be any slamming about as might happen on a full scale plane. What AA5BY describes should immediately clue you in to bad connections or bad servos. The surfaces of full scale are held by the forces the pilot exercises against the stick. Aero forces can slam the stick and surfaces about. Our solid rigging to a powerful enough servo won't allow surface movement it's strong enough to control. Unless the servo is weak or it's gearing compromised or the rigging has slop, there won't be any slamming about.

The solid hold of the servo is the only thing that will experience anything and it will simply feel less force while holding or moving the surface. Thanks to the force generated by the aerotab, the force of the surface is countered to some degree.

What should also be considered is that the part of the surface from LE to TE where the tab is acts as an unchanging camber wing. The part of the span that has a hingeline running through it acts as a variable camber wing. The hinged part will flex itself into a stall much later than the part with the aerotab. You can usually expect the aerotab part to go into stall with not much stick input from your TX. The AOA of that aerotab part of the system won't have much angle to move before that unflexing section reaches it's limit.

When you design in an aero balance tab, you're basically tying a limited AOA part to a part that stalls at quite a significantly larger movement. You can think of it as throwing away some efficiently working area for less force needed by the joystick. We don't have a joystick, we have a TX stick that absolutely controls the surface rigidly. Why do we design models with those tabs? Beats me.
