Control reversal

In reverse the rudder effect is a process of aero-elasticity or a local stall, where the rowing action is contrary to the rudder.

If the reversal of the rudder effect by aeroelasticity, the guide surface is rotated by the control surface, that the overall effect counteracts the rudder. This happens especially at high airspeeds. The Flettner rudder based on this principle.

However, the tears flow from particular to the ailerons, this is done in conjunction with a large rudder deflection due to a very slow airspeed.
