Shallow, full chord fairings enclosed the legs and part of the mainwheels, which had rubber shock absorbers and brakes.
[1][2] The Sauro was powered by a 97 kW (130 hp) Farina T-58 radial engine within a domed cowling that left its five cylinders individually exposed.
The two tandem cockpits, the forward one over the wing and the other just behind its trailing edge, had long headrest deckings behind them that extended to the tail.
The tail surfaces were conventional, steel-framed and covered with a mixture of aluminium and fabric, with the tapered tailplane set at mid-fuselage with an angular fin and rudder above.
[1][2] The Sauro was built at Caproni's main Taliedo works, then tested at Guidonia Montecelio under military markings.
