Ailerons, Rudder & Adverse Yaw RC Model Airplanes
Understanding how ailerons, rudder and adverse yaw affect RC model airplane flight is very helpful to the RC pilot. Proper stick and rudder skills are important to the successful flight of any RC model, to include scale models that might have unique flight characteristics.
Ailerons, rudder & adverse yaw all come into play when learning how to fly a RC airplane. Whenever a pilot turns an airplane, the first control input is ailerons to bank the aircraft, followed by rudder to coordinate the turn. Model aircraft can be turned with rudder only if the model has some inherent stability, such as a high wing trainer. More maneuverable or aerobatic models will require ailerons for proper bank control.
Adverse yaw comes into play when an aircraft, generally, is lightly wing loaded and has a large aileron surface area. This is typical of World War 1 fighter aircraft.
With adverse yaw, the input of a bank command, say to the left, has the right side aileron going down to create more lift to raise the wing. As the aileron goes down, the drag on that side is increased, causing the nose to yaw to the right (opposite the direction of turn). Rudder in the direction of the turn corrects this.
