A tailless aircraft may still have a fuselage and a vertical tail (fin and rudder). Use of Reflex Airfoils Ever notice how many tailless aircraft have wings that curve at the trailing edge? This type of design is a reflex airfoil. Upward Deflection : Raising both elevons decreases the camber of the wing.

They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. 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.
