[1] The Nibio II was a high-wing monoplane with its wing braced by a single faired strut on each side, joining the lower fuselage to the outer end of the central panel at about one third span.
The outer panels were straight tapered to blunt tips, the wing becoming thinner and thus acquiring dihedral though retaining a horizontal upper surface.
Ailerons occupied the whole trailing edges of these outer panels; there were no inboard flaps or air brakes.
[1] Its wood framed, plywood skinned fuselage was hexagonal in cross section, tapering markedly on its underside towards the tail.
The pilot's cockpit, open behind a small windscreen, was immediately ahead of the pedestal and below the wing leading edge.
