Abstract
An aircraft structure, such as a glider including a wing having a substantially flat, upper, first surface and a convex, lower, second surface. The wing first and second surfaces converge to a leading edge and a trailing edge. A weighted member is used to determine the center of gravity of the wing as being 15 to 25% of the length of the chord from the leading edge. The weight structure is fixed to the wing and may also serve as a structural member.
