The V 40 and V 44 were all metal high wing monoplanes, with thick, straight edged, cantilever wings. Highly stressed members were steel, with duralumin elsewhere including the skin. The fuselages were deep bellied and flat sided with tandem open cockpits over the wing. On both aircraft, the pilot sat near the quarter chord position, with a slot in the fuselage below the wing to enhance his downward view, and the passenger was placed within a cut-out in the trailing edge. The tailplane was on top of the fuselage and the rounded vertical tail included a balanced rudder which extended down to the keel. The conventional undercarriage was fixed, with mainwheels on a single axle mounted on short V-struts and assisted by a tailskid.
The V 40 and V 44 airframes were identical but the V 40 was powered by a 75 hp (56 kW) Siemens-Halske Sh 11 7-cylinder radial and the V 44 by a 100 hp (75 kW) Bristol Lucifer 3-cylinder radial. Both were nose mounted, uncowled, and drove two blade propellers. External dimensions, apart from the exact length were the same and the weights were also similar.
