A tailless aircraft may still have a fuselage and a vertical tail (fin and rudder). Upward Deflection : Raising both elevons decreases the camber of the wing. Downward Deflection : When the elevons are lowered, the camber increases. The rudder allows you to make controlled yaw movements. How does it manage yaw control?

A pilot can prevent adverse yaw by using rudder, and making sure that a turn is coordinated. In this situation, you must add the right rudder to correct for adverse yaw. An increase in AOA causes an increase in the wing’s effective camber, which in turn causes an increase in profile drag. What is Adverse Yaw?

Adverse yaw is a side effect of aileron use, countered by rudder input. The asymmetry between the top and bottom surface of the wing is called wing camber. The downward movement of the aileron increases the asymmetry and, therefore, the camber while raising the aileron reduces the wing camber. What Is an Aileron?

The aileron on the right wing deflects down, increasing the camber and creating more lift. We counteract adverse yaw by applying rudder in the direction of the turn. The amount of rudder required depends on roll rate and airspeed. Airspeed and attitude change constantly, and we must change rudder input along with them.

One is the upper wing surfaces curvature compared to the lower surface, called wing camber. High camber generally promotes more airflow deflection, thanks to something called Bernoullis Principle. However, its even possible to generate lift from a wing with symmetrical upper and lower surfaces, that is, without camber.
