The Supergrifo design began as an attempt to improve upon the Grifo but evolved into a much higher performance aircraft.
It was a braced high-wing monoplane, its single spar wing having a centre section, covering about one third of the span, which was rectangular in plan and had slight dihedral.
[1] The Supergrifo's fuselage was a ply covered wooden hexagonal structure with deep sides.
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 Supergrifo's landing skid, equipped with rubber shock absorbers, reached aft to the rear wing strut.
