From the gaps at the root and tip for the aileron horns, there's a modest amount of "Frise aileron" effect, where the inner portion of the leading edge of the downward deflected surface projects below the surface of the wing proper, to provide a small amount of drag on that side offsetting the adverse yaw of the downward deflected aileorn on the other side.
Not commonly done, but not of any particular worry, if replicated 100% or not.
