The LFG V 40 and V 44 were one-off, single-engine, two-seat sports monoplanes, identical apart from their engines, built in Germany in 1925.

Highly stressed members were steel, with duralumin elsewhere including the skin.

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.
