The Civil Aviation Department Revathi was a light utility aircraft designed in India principally for use by that country's flying clubs.
The Davis DA-5, a.k.a. DA-5A, is a single-seat sport aircraft designed in the United States in the 1970s and marketed for homebuilding. Like designer Leeon D. Davis's successful DA-2, it is a low-wing monoplane with fixed tricycle undercarriage and a V-tail, but with a much narrower fuselage accommodating only the pilot, and a lengthened nose. Design work was carried out in 1972, but the prototype was not built until 1974, when it was completed in only 67 days.
The DSK Airmotive DSK-1 Hawk was an unusual homebuilt aircraft designed in the United States in the early 1970s. While the design itself was utterly conventional - a single-seat low-wing cantilever monoplane with fixed tricycle undercarriage - its method of construction was not, since the DSK-1 Hawk used a surplus 200 US Gal military drop tank as its fuselage. Designer Richard Killingsworth sold over 250 sets of plans.
The Fauvel AV.50 Lutin was a design for an unorthodox light aircraft produced in France in the 1970s. Like some other Charles Fauvel designs, it was a tailless aircraft with a reverse-delta wing. In this case, it was a single-seater intended to be powered by a converted Volkswagen engine. Only one example was known to have been under construction by 1977, in Australia.
The Fike Model E was a light aircraft built in the United States in the early 1970s. Designed by airline pilot William Fike, it was a conventional high-wing cantilever monoplane with tailskid undercarriage and seating for one or two people in an enclosed cabin. The wing was an unusual geodesic wooden construction and was of far greater chord than typical for an aircraft of this type; indeed, one of the purposes of building the aircraft was to investigate the characteristics of a wing of such low aspect ratio (3.0). The empennage was taken from a Piper Cub, but was modified to reduce its span to make it suitable for towing on the road. Plans were made available for homebuilders in the mid 1970s.
The Gatard Statoplan AG 02 Poussin was a light, single-seat sports airplane developed in France in the late 1950s and marketed for homebuilding. In layout, it was a low-wing cantilever monoplane of short-coupled design with fixed tailwheel undercarriage. Construction was a plywood-covered wooden structure throughout, and the cockpit was enclosed by a large perspex bubble canopy. The variable-incidence horizontal stabiliser was fitted with small endplates to provide extra directional stability but there were no separate elevators.
The Issoire Silène was a sailplane produced in France in the 1970s and early 1980s, intended primarily as a trainer. It was a conventional design of fibreglass construction in versions with fixed or retractable monowheel undercarriage. The aircraft featured side-by-side seating for two, with the seats slightly staggered in order to minimise fuselage width. French certification was obtained on 3 February 1978, and production began shortly thereafter at the rate of two aircraft per month.
The Jeffair Barracuda is a high-performance sporting monoplane that was developed in the United States in the 1970s and is marketed for homebuilding. Designed and built by Geoffrey Siers, the prototype won the prize for "Most Outstanding New Design" at the EAA Fly-in in 1976. It was a low-wing cantilever monoplane of wooden construction with retractable tricycle undercarriage and side-by-side seating for two. Around 150 sets of plans had sold by 1977.
The Kraft K-1 Super Fli is a single-seat sport aircraft that was designed in the United States in the early 1970s and marketed for homebuilding. It is a low-wing cantilever monoplane of conventional design with fixed, tailwheel undercarriage. The wings have a wooden structure, skinned in plywood, while the fuselage and empennage are built from steel tube, the fuselage skinned in aluminium and the tail in fabric. It has a very similar design to radio controlled craft.
The Lederlin 380L is an unconventional light aircraft developed in France in the 1960s, and marketed for homebuilding.
The Lefebvre MP.205 Busard was a single-seat racing aircraft built in France in 1975 and marketed for homebuilding. Its design was adapted from that of the Lefebvre MP-204 'Busard' racer, that had been conceived to attempt a world airspeed record in the under 500 kg class in 1949. Compared to its predecessor, the Busard was lightened and intended to be powered by a lower-power engine, and simplified for construction by amateurs. Indeed,the prototype was built by the designer with assistance from students at the Albert Camus technical school of Rouen. Like the MP.204 that it was based on, the Busard was a streamlined, low-wing, cantilever monoplane of conventional design with fixed, tricycle undercarriage. Provision was made for the use of either an aero engine, or a Volkswagen automotive engine.
The MacDonald S-20 is a single-seat sport aircraft that was designed in the United States in the early 1970s and marketed for home building.
The McCarley Mini-Mac was a single-seat aerobatic sport aircraft designed in the United States in the early 1970s and marketed for home building. It was a conventional, low-wing cantilever monoplane with a cockpit enclosed by a bubble canopy. The undercarriage was of fixed, tricycle type with spats fitted to the prototype, as well as a small skid fitted as a tail bumper. Construction was of metal throughout.
The Miller WM-2 was a single-seat sport aircraft designed in the United States in the early 1970s and marketed for home building. Although primarily a powered aircraft, the WM-2's high aspect-ratio wings enabled the pilot to stop the engine and soar on thermals as with a sailplane.
The Mini-Hawk TH.E.01 Tiger-Hawk was a single-seat sport aircraft designed in the United States in the early 1970s and marketed for home building. It was a conventional, low-wing cantilever monoplane with a cockpit enclosed by a bubble canopy. The wings were detachable for ease of storage or towing and could be rigged in around ten minutes. The undercarriage was of fixed, tricycle type with spats fitted to the prototype. It was an all-metal construction, and the aircraft could be built from plans or a kit.
The Piel CP.70 Beryl is a French twin-seat, single-engine sport aircraft designed by Claude Piel. It was first flown in France in the 1960s and marketed for amateur construction.
The Piel CP.80 Zephir , Piel CP.801 and Piel CP.802 are racing aircraft developed in France in the 1970s and marketed for homebuilding. They are compact, single-seat, single-engine monoplanes with low, cantilever wings.
The Piel CP.90 Pinocchio II was a single-seat, single-engine aerobatic sport aircraft developed in France and marketed for homebuilding. The design was based on that of Piel's Emeraude and was unrelated to Piel's first design named Pinocchio, the CP.10 and indirectly to the second, the CP.20. It was a cantilever, low-wing monoplane of conventional design with an enclosed cockpit and fixed, tailwheel undercarriage. Construction was of wood throughout.
The Piel CP.500 was a light aircraft of unusual configuration designed in France in the 1970s with the intention of marketing it for homebuilding. This did not transpire, however, and no prototype was actually built. It was a tandem wing design, somewhat reminiscent of the Mignet Pou-du-Ciel but considerably larger. Also, unlike the Pou-du-Ciel's unusual control system, the CP.500's pitch and roll control was to come from more conventional elevons mounted on the rear wing. The rear wing was also to carry endplate-style fins and rudders. Twin engines were to be mounted in push-pull fashion at the nose and tail ends of the fuselage, with the aircraft capable of single-engine operation in case of emergency. Two seats were to be provided at the front of the fully enclosed cabin, with a bench seat for three passengers behind them, plus an optional seat for a sixth occupant behind this. The undercarriage was to be of fixed, tricycle configuration. Construction was originally planned to be of wood, with engine cowlings and wingtips of composite construction. However, as development progressed, Piel considered metal as the main construction material.
The Pottier P.70 was a single-seat, single-engine sport aircraft developed in France in the 1970s and marketed for homebuilding. It was a mid-wing cantilever monoplane of conventional design with an enclosed cockpit. Originally designed with fixed, tricycle undercarriage, the plans were later revised to offer a fixed, tailwheel option. Construction throughout was of metal. A two-seat, tandem version was developed as the P.170.
