The Dornier Do K was a German commercial passenger and freight monoplane, designed by Claude Dornier and built by Dornier Flugzeugwerke. [1] Only three prototypes of different designs were built and the type was not a commercial success. [1]
The first Dornier Do K was the K1 which first flew on 7 May 1929. [1] The K1 was a conventionally-braced high-wing monoplane, powered by a single nose-mounted 510 hp (380 kW) licence-built Bristol Jupiter VI radial engine, and had a conventional landing gear with a tailskid. [1] The square-section fuselage had an enclosed cockpit for two with a cabin behind for freight or eight passengers. [1] Test flights showed that performance was poor and the aircraft was redesigned. [1]
The Do K2 flew in December 1929 with similar wings and fuselage but had a changed landing gear and four 240 hp (179 kW) Gnome-Rhone Titan radial engines. [1] The four engines were strut mounted on each side of the fuselage in tandem pairs, one in tractor configuration and the other as a pusher. [1] Although the aircraft had an increase in available power, the performance was little improved on the K1. [1]
The K3 was a complete rethink of the design. The braced wing was replaced with a cantilever wing of larger span. [1] The fuselage was changed to oval and stretched for two extra passengers and the tailskid was replaced with a tailwheel and the main units were enclosed in fairings. [1] The four engines were in the same tandem arrangement as the K2, but located lower on the fuselage and changed to 305 hp (227 kW) Walter Castor radial engines. [1] The performance was greatly improved but still provoked little interest and no others were built. [1]

The Hispano Suiza E-30, later renamed Hispano E-30, was designed in Spain in 1930 as a multi-purpose intermediate trainer. It was a single engine, parasol wing monoplane. About 25 served with the Spanish armed forces until 1945.
The Dewoitine D.35 was a small, single-engine passenger transport aircraft built and flown by Dewoitine in France for their own use in the early 1930s. Only one was produced.
The Yakovlev AIR-7 was a prototype Soviet high performance light aircraft of the 1930s. It was a two-seat single-engined monoplane, which demonstrated excellent performance during testing. After the prototype almost crashed as a result of flutter, its designer, Alexander Sergeyevich Yakovlev suffered temporary disgrace and no production followed.
The Darmstadt D-29 was a German experimental monoplane designed and built by Akaflieg Darmstadt. The D-29 was a cantilever low-wing monoplane designed and built during 1936 with a conventional landing gear with a tailskid. It was powered by a Siemens-Halske Sh 14a radial piston engine and had enclosed tandem cockpits, as well as a number of other features, including hydraulically actuated trailing-edge flaps, a braced T-tail and leading-edge slots.
The Yakovlev AIR-5 was a prototype Soviet single-engined cabin monoplane designed by the Yakovlev design bureau. The AIR-5 was a high-wing strut-braced monoplane with a 200 hp (149 kW) Wright J-4 Whirlwind engine. It had a tubular steel fuselage, wooden wings and an enclosed cabin for a pilot and three passengers.

The SABCA Demonty-Poncelet monoplane, Demonty-Poncelet limousine or SABCA-DP was a Belgian light aircraft first flown in 1924. It had two comfortable side-by side seats in a glazed cabin. Though it had competition successes in 1924 and 1925, it did not go into production.
The Cairns A was a low wing, two tandem seat monoplane with a metal structure and stressed metal skin. It first flew late in 1931 with a 90 hp (67 kW) engine but was later fitted with more powerful engines including a 185 hp (138 kW) radial.
