Built by the U S Airplane Co in 1928, the U S Flyer prototype NX6605 c/n11 was designed by L B Coombs and priced at $2,250-6,500. Originally powered by a 110 hp Anzani engine, the only one built was later powered with 90hp Curtiss OX-5 and Wright Whirlwind.

The Toadstabber was built in 1934 by Alfred H Urness & Henry J Hanson of Cashton WI. USA.
A single place, open monoplane, it was powered by a 36hp Ford engine and registered N13652 c/n HU-2.
The second design of Vilém Urbánek (sometimes identified as Urbánek II) which was exhibited at the Prague Automobile Salon of 1910 in an unfinished form. The aim of Urbánek was to design an “automatic” device for lateral control.
In the available photographs of the machine can be seen a long construction of lattice fitted before the wing used in such a way that when one wing half dropped (or rose) the other wing half would automatically compensate in the opposite direction. The machine was never finished, so it was never determined whether the automatic stability system devised by Urbánek would work in actual flight.

The 1934 Universal Aircraft Co 98 Trainer was a 1-2 place open cockpit biplane powered by a 40hp Ford A engine. Six were registered: N13950 c/n 3, N13973 c/n 7, N13999 c/n 18, N14884 c/n 11, N15179 c/n 10, and one with a 50hp Ford engine: N11597 c/n 50.
Others appear in the registrations as “Univeral 36” with a 40hp Continental (eg: 17671 c/n 7186-F), but the c/ns suggest those were American-Universal Flying Fleas.
Work was begun, in 1968, on the AUM-903 three-engined STOL light transport project.
Aeronautica Umbra’s design office was responsible for a heavy fighter of advanced and unorthodox design, the M.B.902 designed by Ing. Bellomo. The M.B902 was actually built, although flight testing had not commenced when the prototype was destroyed.
The construction of the M.B.902 was begun in 1942, and this single-seat fighter was unusual in being powered by a pair or 1,250 h.p. Daimler-Benz DB 605 liquid-cooled engines buried in the fuselage and driving twin contra-props mounted outboard on the wings via extension shafts. Featuring a retractable nose wheel undercarriage and carrying an armament of four 20-mm. and two 12.7-mm. guns, the M.B.902 had an estimated maximum speed or 429 m.p.h., and a maximum range of 1,056 miles.
The A.U.T.18 – the designation signifying Aeronautica Umbra S.A., the manufacturer, Ing Felice Trojani, the designer, and the originally-planned wing area of 18sq.m – was an all-metal stressed-skin single-seat fighter, one example of which was ordered in 1936 for evaluation by the Regia Aeronautica. Unusual among contemporary Italian single-seat fighters in having its armament of twin 12.7mm guns mounted in the wings, the A.U.T.18 was powered by a Fiat A.80 R.C.41 18-cylinder radial engine rated at 1030hp for take-off, and flew for the first time on 22 April 1939. Initial trials were performed with an NACA-type engine cowling, but this was supplanted from April 1940 by a close-fitting cowling with the rocker arms partly enclosed by fairings. Evaluation of the sole prototype was completed on 5 November 1940, when the aircraft was delivered to the Regia Aeronautica, but the Ministero dell’Aeronautica did not consider that the Trojani fighter offered any advantages over the Macchi C.200 and Fiat G.50, both of which were in production, and further development of the A.U.T.18 was discontinued.

The Urban Air UFM-13 Lambada is a two-seat side by side mid-wing motorglider / ultralight aeroplane. The UFM-13 Lambada is developed and built by Urban s.r.o. in Czech and is constructed from composite with sandwich construction. The prototype of the side-by-side two-seat Lambada flew first in May 1996. This UL-plane is a taildrager with quickly dismounting wings. The wings with a total wingspan of 12 meter, quickly to increase by mounting 2 x 1,5 meter wingtips into 15 meter, giving the Lambada excellent gliding performances.
Versions: UFM 13/15 Lambada S-LSA. New versions for the US market equipped with ailerons. Wingspan from 46.6 to 49.0 ft (optional wingtips).
Design features: Conforms to ASTM, JAR-VLA (BCAR-S). Wings and HTU easily detach (self control lines connections) for storage and transport.
Flying controls: UFM 13/15 Lambada is controlled by conventional ailerons, rudder, one-piece elevator and upper surface spoilers.
Structure: Laminated glass fibre and carbon fibre with CFRP wing spar.
Landing gear: Fixed tricycle or tailwheel type. Hydraulic brakes. 2009 Price: 48000 EURO
