Infos techniques | The B-6 Initially flown in 1981, the B-6 used the same fuselage as the last version of the B-5, and retained the pylon-mounted adjustable thickness wing. Very distinctive upswept wing tips were used, on a fixed 22 m wing span. Version 2 of the B-6 finally dispensed with the adjustable thickness wing. Instead, the aft 40% of the wing skins were flexible, for camber adjustment. Very small (10 % of chord) ailerons were used. The wing structure consisted of an aluminium spar, with plywood ribs and aluminium skins. Although performance seemed quite good, the small ailerons resulted in inadequate feedback, which made the glider rather difficult to fly. | ||||||
