A flight control system and method for controlling the flight of a fixed-wing model aircraft is disclosed. The flight control system may actively sense the condition when the wings of the model aircraft are not level to the horizon. The flight control system may then command the servo(s) to control movement about the roll and the yaw axes of the aircraft in order to level the wings to the horizon. In addition, the flight control system may limit the maximum bank angle that can be achieved even when full roll control is commanded by the operator. The flight control system in accordance with the present disclosure may allow inexperienced operators to fly model aircraft successfully by eliminating/mitigating adverse effects that may cause the operators to lose control.
