 The aircraft had a right-handed, three-bladed Piaggio P.2001 constant speed, mechanically controlled, variable-pitch metal propeller.The streamlined but tiny fuselage was almost totally dominated by the DB 605 engine with little room for fuel storage.The fuselage-mounted MG 151/20 cannon had less ammunition than those mounted in the wings (150 rounds versus 170 rounds in the wing gun bays from the second prototype on).
