Wings are long and pointed tapering toward wing tip. This cartilage along with the manus forms a wing tip to be used during gliding. There is a rod antenna at each wing tip for HF communication. It is curved to behind, resulting in a rounded wing tip, which reduces induced drag. The optional weather radar pod is smoothly blended into the left wing tip. In most families a conspicuous pterostigma is carried near the wing tip. Two wing tanks, a fuselage tank and two wing tip tanks. The transverse fold of the hind wing is near the wing tip. This reduces the pressure gradient at the wing tip, therefore also reducing lift. The complete left wing tip was found a little under from the crash site. When one wing tip stalls it leads to wing drop, a rapid rolling motion. Loss of control may occur if one wing tip stalls in ground effect. After being extended, the wing tip may adjust to various angles, controlling aerodynamic movements.
