A system for controlling an aircraft includes an airframe, a first airfoil, and a second airfoil. At least a portion of the first airfoil and the second airfoil are controllably deflectable so that, during a roll maneuver, the first airfoil generates increased lift and a consequent increased drag, and the second airfoil generates negative lift and a consequent increased drag, the increased lift and the decreased lift generating a roll moment, and the increased drag of the second airfoil producing a yaw moment that counteracts the yaw moment produced by the increased drag of the first airfoil such that no substantial change in aircraft yaw moment occurs. The drag on the down-going wing may counteract the drag on the up-going wing by having a reduced area providing the down-going force so that it has to deflect to the point that it is producing not only less, but actually negative lift.
