Design and development
The Grifo single-seat trainer was intended as an improved version of the Teichfuss Nibio I. It was a braced high-wing monoplane, with a single spar wing. Apart from full rounded wing tips the wing was rectangular in plan, with plywood covering from the spar forward around the leading edge forming a torsion resisting D-box. Aft of the spar the wing was fabric-covered. Ailerons occupied more than half the span. The wing was held over the fuselage on a pedestal and braced on each side by a pair of parallel faired struts to the lower fuselage.
The Grifo's fuselage was a ply covered wooden hexagonal structure with deep sides. The open cockpit, fitted with a small windscreen, was immediately ahead of the pedestal which dropped rapidly away to the upper fuselage behind the trailing edge. All the tail surfaces were straight-tapered and straight-tipped, with the tailplane mounted on top of the fuselage and carrying unbalanced elevators. The fin was small but mounted a large, balanced rudder which extended down to the keel, working in an elevator cut-out and provided with a protecting tail bumper. The Grifo's landing skid, equipped with rubber shock absorbers, was short, only reaching as far aft as the forward wing strut.
The Grifo first flew in 1934. Three were built and used by flying clubs.
