Design and development
The Mantelli-Fossa MF-1 was designed by Adriano Mantelli, an experienced aircraft modeller. To fund its construction, Mantelli, his cousin Dino Sirocchi and some other aircraft modellers founded a company named SDAM after their senior partners' initials. The MF-1 was built by Ennio Fossa in his family workshop. It was a high-wing monoplane, its wing supported centrally on a fuselage pedestal and braced on each side with a faired V strut from beyond mid-span to the lower fuselage. It was mounted without dihedral and was rectangular in plan apart from cropped aileron tips.
The fuselage, rectangular in cross-section though with a rounded decking, was entirely fabric-covered. There was an open cockpit immediately ahead of the pedestal. Aft of the wing the fuselage tapered to the tail, where a triangular tailplane with rectangular elevators was placed on top of it. The fin was small and triangular and carried a straight-edged balanced rudder which extended down to the keel, operating in an elevator cut-out. The MF-1 landed on a conventional wooden skid fitted with rubber shock absorbers, assisted by a very small tail skid.
Mantelli flew the MF-1 for the first time on 14 August 1934. Later that year he competed in it at Cantù in the Littoriali Contests.
