In 1918, Adamoli and Cattani designed the smallest possible single-engine seat fighter around the most powerful rotary engine available, the 200-hp (149-kW) Le Rhone. With conventional wooden construction and fabric covering, the fighter was unequal-span unstaggered biplane with Warren truss-type interplane bracing. Lateral control was by interlinked and hinged wing leading edges varing the wing’s camber tip. Rigid tubes were used to actuate the movable tail surfaces. Construction of the prototype Fighter began at the Farina works in Turin, but was then transferred to the Officine Moncenisio in Condove for completion. Initial static testing revealed that the engine only developed 160hp (119 kW) and the fighter would be seriously underpowered. These limited trails took place at the end of WW1 and further development of the fighter was abandoned after the Armistice.
