An ultra-light aircraft of light-weight minimal construction includes a rigid wing from which a hang cage is suspended by a main hinge assembly. Rotation of the wing without pilot intervention induced by positive or negative wind gusts striking the wing causes the angle of pitch between the wing and hang cage to vary via the hinge so that the wing presents a relatively constant angle of attack to relative wind enabling the aircraft to be essentially stall free during flight. Twist and/or dihedral of the wing is maintained by first and second sets of tens...
An aircraft, comprising: (a) a fuselage; (b) a rigid wing having forward and rear tubular members acting as load bearing members connected to extend transversely from opposite sides of the fuselage to respectively establish leading and trailing wing edges, said forward and rear members being connected together by short longitudinal tubes to define a wing frame therewith with one of said tubes located centrally between opposite ends of the wing being a keel, and fabric material and the like covering the wing frame to establish lifting surfaces exposed to ...
