The Auster Avis was a four-seat light aircraft developed from the Auster Autocrat. It featured a redesigned fuselage incorporating four doors and a circular cross-section towards the tail, new undercarriage, and new wing flaps. It was planned in two versions, the Mk 1 for civil use, and the Mk 2 for military and air ambulance duties. However, only two prototypes were built, and Auster abandoned the project in favour of the Auster J-5 Autocar.
The Bartlett LC-13A Zephyr 150 was a United States light civil aircraft built in the 1940s. It was a mid-wing braced monoplane of conventional design with side-by-side seating for two and fixed, tailwheel undercarriage. It was originally marketed as the Babcock LC-13 by its original manufacturer, then as the Taubman LC-13 when the Babcock Airplane Corporation was acquired by Taubman Aircraft. The rights were finally acquired by Bartlett Aircraft in 1941, but plans to mass-produce it were halted by the outbreak of World War II. There was a brief attempt to revive the design at the end of the war, but nothing came of this.

The Hopfner HS-8/29 was a utility aircraft built in Austria in the late 1920s based on the Hopfner HS-5/28. It used a modernised version of its predecessor's airframe, being a conventional, parasol-wing monoplane with seating for two occupants in tandem, open cockpits. The landing gear was of fixed, tailskid type with divided main units. The first prototype used the same Walter NZ85 engine that the later HS-5/28s had used, but this was followed by 14 production examples with Siemens engines, and a single prototype with a de Havilland Gipsy III.

The Renard Epervier was a Belgian prototype single-seat all-metal fighter monoplane designed by Alfred Renard at the Societé Anonyme Avions et Moteurs Renard for a government-sponsored design contest in 1928. The Epervier Type 2 was built and flown in 1928, by Belgian aircraft manufacturer Stampe et Vertongen. It carried an armament of two synchronised 7.7mm guns and was lost in September 1928 after failing to recover from a flat spin. A second prototype, the Epervier Type 2bis, introduced revised streamlined fairings for the cantilever mainwheel legs, mainwheel spats and cylinder aft-fairings and was built by SABCA.
The Renard R.17 was a Belgian four-seat cabin monoplane designed and built by Constructions Aéronautiques G. Renard. The high cantilever wing was an unusual feature when most contemporary aircraft still had braced wings. Designed as a high-speed transport for fresh flowers, no aircraft were ordered and the only R.17 was retained by the company until 1946.

The stubby lower wings carried the divided main units of the fixed undercarriage. The fuselage was of rectangular cross-section and featured a fully enclosed flight deck and passenger cabin. The tail was of conventional design with strut-braced stabilizers and carrying a fixed tailwheel. Construction was of metal throughout, and the aircraft was powered by a single radial engine in the nose.
