The Tupolev design was advanced but lacked refinement, much to the dismay of crews, maintenance personnel, and Stalin, who pointed out that "there are no trivialities in aviation".
The Fiat CR.1 was an Italian biplane fighter aircraft of the 1920s. Of wood-and-fabric construction, it was designed by Celestino Rosatelli, from whom it gained the 'CR' designation. Its most distinctive feature was that the lower wings were longer than the upper ones.

The Hanriot HD.14 was a military trainer aircraft produced in large numbers in France during the 1920s. It was a conventional, two-bay biplane with unstaggered wings of equal span. The pilot and instructor sat in tandem, open cockpits, and the fuselage was braced to the lower wing with short struts. The main units of the fixed tailskid undercarriage were divided, each unit carrying two wheels, and early production examples also had anti-noseover skids projecting forwards as well.
The Hanriot HD.17 was a French trainer seaplane of the 1920s. It was essentially a floatplane version of the ubiquitous HD.14 with a revised tail and a more powerful engine. Over 50 examples were operated by the Aéronautique Maritime, of which seven were converted to landplanes. A small number of HD.17s were exported to Estonia and Latvia. Further development resulted in the HD.41H.
The Hanriot HD.28 was a military trainer aircraft developed in France in the 1920s as a modernised version of the HD.14 for export markets. The principal difference between the types was that while the HD.14 had an entirely wooden structure, the HD.28's structure was almost entirely of metal. The landing gear was also of more conventional design, with only one wheel on each main unit, plus small anti-noseover skids. The two tandem cockpits of the HD.14 were replaced by a single, long cockpit in which both pilot and instructor sat.

The Stampe et Vertongen RSV.22 was a training biplane produced in Belgium in the 1920s.
The Hanriot HD.5 was a French two-seat fighter aircraft prototype, built towards the end of World War I. A single-engine biplane with an unusually narrow gap between the upper and lower wings, it did not enter production.
The Hanriot HD.15 was a French two seat fighter aircraft fitted with a supercharger for good high altitude performance, built in the 1920s. Three were ordered by Japan but lost at sea during delivery.
The Hanriot H.110 was an unusual pusher configuration, twin boom, single seat fighter aircraft built in France in the early 1930s. It proved to be slower and less manoeuvrable than its contemporaries and failed to reach production, even as the Hanriot H.115 after receiving a more powerful engine and cannon armament.
The Hanriot H.34 was a basic trainer designed in France in 1924 which did not reach production. It was a parasol wing aircraft, seating two in tandem.
The Hanriot H.38 was a French twin-engined sesquiplane flying boat built in the mid-1920s. Though the sole prototype was fitted with two defensive machine gun posts. the H.38 was described at the time as a utility aircraft.
