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.
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. [1]
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. [1]
The V 40 and V 44 were amongst five LFG entries to the Round Germany Flight held in the summer of 1925, though only the LFG V 39 took take part. [1] [2]

General characteristics
Performance
The Albatros L 59 was a single-seat German utility aircraft of the 1920s. It was a single-engine low-wing cantilever monoplane with large, spatted wide track undercarriage attached, unusually for the time not to the fuselage but to the wing roots. The whole aircraft was covered in 3-ply.
The Albatros L 69 was a two-seat German parasol monoplane racing and training aircraft of 1925. It was a single-engine parasol-wing monoplane of conventional configuration that seated the pilot and passenger in tandem, open cockpits. It was advertised as a trainer, however contemporary reports dismissed this due to the difficulty in accessing the front cockpit, and the designers' focus on performance.
The Arado S I was a biplane trainer built in Germany in 1925. The first of three prototypes was powered by a Bristol Lucifer radial engine, while the other two Arado S.Ia aircraft were fitted with the Siemens-Halske Sh 12. The Siemens-Halske Sh 11 powered the Arado S III, a virtually identical aircraft of which only a single prototype was constructed and sold to Turkey.
The Dornier Libelle, also designated Do A, was a German open-cockpit, all-metal, parasol wing, monoplane flying boat aircraft, with partly fabric-covered wings. A landplane version, built without sponsons and fitted with a fixed tailwheel undercarriage was produced as the Dornier Spatz.
The Focke-Wulf A.16 was a German three/four passenger light transport monoplane designed by Heinrich Focke and Georg Wulf and was the first design built by the newly formed Focke-Wulf company.
The ICAR Universal was a 1930s Romanian two seat monoplane trainer, touring and aerobatics aircraft.
The Junkers K 16 was a small airliner produced in Germany in the early 1920s. It was a conventional, high-wing cantilever monoplane of all-metal construction, equipped with fixed, tailwheel undercarriage. The pilot sat in an open cockpit, while the two passengers were provided with an enclosed cabin within the fuselage. Shortly after the prototype flew, aircraft production in Germany was brought to a complete halt by the Allies, and the K 16 was quickly evacuated to the Netherlands to avoid confiscation. There, it was stored by Fokker until the restrictions were relaxed and work recommenced at Junkers' Dessau factory in 1924. By this time, however, the airline niche that the tiny K 16 had been intended to fill no longer existed, and the small number that were produced were mostly sold to private owners. Junkers entered two K 16s in the 1925 Deutsche Rundflug, with one machine winning second place in the competition.
The Siemens-Schuckert DDr.I was a World War I German twin engine, push-pull configuration triplane fighter aircraft. Only one was built, crashing on its first flight.
The LFG Roland D.IX was a World War I German single seat fighter aircraft, a biplane powered by one of a new generation of powerful rotary engines. Three slightly different prototypes were built but there was no series production.
The LFG Roland D.XVI, initially designated the LFG Roland E.I, was a single-seat, single-engine, parasol wing German fighter aircraft flown close to the end of World War I. Only two were built.
The LFG V 39 was a simple biplane trainer built in Germany in the mid-1920s. It took part in the Round Germany Flight in the summer of 1925.
The V 42 was a one off, single-engine, two-seat sports monoplane, built in Germany in 1925.
The V 52 was a one off, single engine, two seat sports monoplane, built in Germany in 1925.
The Albatros L.71 was a two-seat, single pusher engined biplane built in Germany in the 1920s.
The Siemens-Schuckert B was an unarmed German two seat reconnaissance biplane built early in World War I. A single example was delivered but soon lost.
The Udet U 1 was the first of a line of small, low-powered, low wing, cantilever monoplanes built in Germany in the early 1920s.
The Dietrich-Gobiet DP.VII was a simple, low power, German sports aircraft flown in early 1924.
The parasol wing, single engine Udet U 8, sometimes referred to as the Limousine, was a three-seat commercial passenger transport designed and built in Germany in 1924. Five were produced and were used by German airlines until about 1928.
The Grulich S.1 was a German parasol monoplane with a cantilever wing, built in the mid 1920s. It seated two and offered a choice between two engines.
The Raab-Katzenstein KL.1 Schwalbe (Swallow) was a German two-seat biplane produced in the 1920s. About fifty were built and the type became well known as an aerobatic aircraft, performing at many displays in the hands of pilots like Gerhard Fieseler.
