This could be good or bad depending upon what you want. The latest Pitts aircraft use a narrowing aileron gap near full deflection to reduce the effort required by the pilot to get full deflection. I believe it has something to do with the forward edge of the aileron deflecting above (or below) the wing contour and experiencing a suction from the airflow. Carefully tailoring the wing/aileron gap allows the aileron forces to be reduced. This replaces the spades that you often see on the bottom side of ailerons on many aerobatic competition ships.
