The Caproni Ca.124 was a cantilevermid-wingmonoplane of mixed construction. The fuselage was corrugated-skinned and the empennage cantilever and conventional, with the tailplane set at mid-fuselage. The pilot's cockpit was forward of the leading edge. It was a floatplane, mounted on metal floats each attached to the wings by pairs of N-form laterally orientated struts.[1]
The Ca.124 was powered by a 900 hp (670 kW) Isotta Fraschini Asso XI.RC15, a water-cooled upright V-12 engine, supercharged to maintain power to 1,500 m (4,920 ft). Bombs were contained within the fuselage, below the wing.[1]
