The Lockspeiser LDA-01 ("Land Development Aircraft") was a British seven-tenths scale research and development tandem wing aircraft, [1] which was designed and built by test pilot and engineer David Lockspeiser [2] to prove a concept for a low-cost utility transport.
The LDA-01 was a single-seat tandem-wing monoplane, fabric covered with metal construction. The foreplane had a common design to the separately-made port and starboard wings of the main plane, giving it half the area. The intention was to reduce the number of spare parts needed by re-using the same wing component interchangeably in each location. [3] The main wings were mounted at the rear-end of the box structure fuselage and the fore wing was attached underneath the front. The fuselage was fitted initially with a four-wheeled landing gear and was designed to be fitted with a detachable payload container to allow easy conversion between roles. The landing gear was changed later in development to a more conventional tricycle configuration. It was powered by a rear-mounted pusher engine. The LDA-01 G-AVOR first flew on 24 August 1971 at Wisley in Surrey, under the power of an 85 hp (63 kW) Continental C85 piston engine, but was later refitted with a more powerful Lycoming O-320 engine.
The aircraft (which by this time had been re-registered G-UTIL), and had been renamed the Boxer 500, was being modified to planned production configuration by Brooklands Aerospace at Old Sarum Airfield when it was destroyed in a fire on 16 January 1987. [4] [5] [6]

General characteristics
Performance
The Aero Boero AB-115 is an Argentine civil utility aircraft. It was developed from the AB-95-115, a refined AB-95 with a more powerful engine and improved aerodynamics. Specific differences included wheel spats, a redesigned engine cowling molded of fiberglass, and aluminum ailerons and flaps.
The Piper PA-15 Vagabond and PA-17 Vagabond are both two-seat, high-wing, conventional gear light aircraft that were designed for personal use and for flight training and built by Piper Aircraft starting in 1948.
The Curtiss-Wright X-19, company designation Model 200, was an American experimental tiltrotor aircraft of the early 1960s. It was noteworthy for being the last aircraft of any kind manufactured by Curtiss-Wright.
The Rutan VariViggen is a homebuilt aircraft designed by Burt Rutan. The aircraft is a tandem two-seater of primarily wooden construction with a delta wing and a canard foreplane. The VariViggen is powered by a 150 hp Lycoming O-320 aero engine in pusher configuration. The prototype was designated Model 27, and the production version was Model 32.
The Piaggio P.136 was an Italian twin-engine amphibian flying boat designed and manufactured by aircraft company Piaggio Aero. It is furnished with an all-metal hull, pusher propellers, a gull wing, and retractable landing gear.
The Curtiss-Wright CW-1 Junior, originally named the Curtiss-Robertson CR-1 Skeeter is a light sports aircraft produced in the United States in the 1930s. It had been intended to sell it for the price of a mid-range automobile.
The Grob GF 200 was a business aircraft of unorthodox design developed in Germany during the 1990s.
The Malmö MFI-10 Vipan was a four-seat light utility monoplane designed and built in Sweden by Malmö Flygindustri. Only three aircraft were built and the type did not enter quantity production.
The Boulton & Paul P.12 Bodmin was an experimental British twin-engined biplane bomber with its engines mounted in a fuselage engine room and with tandem pairs of tractor and pusher airscrews mounted between the wings. The two Bodmins built flew in 1924, proving the concept but the layout was not developed to production.
The Stout Skycar was a series of four one-off American light aircraft of the 1930s.
The Miles M.35 Libellula was a tandem wing research aircraft built by Miles Aircraft as a precursor to a proposed naval carrier fighter. It was named after the Libellula, a genus of dragonflies.
The Dornier Do 29 was an experimental aircraft developed by Dornier Flugzeugwerke and the Deutsche Versuchsanstalt für Luftfahrt in the 1950s, used to test a tilting-propeller system for short takeoff and landing (STOL) aircraft. The concept was proved to be successful in flight testing; however, no further development of the system or aircraft was proceeded with, and at the conclusion of its test program the Do 29 was retired.
The Aeronix Airelle is a tandem wing ultralight with twin engines in push-pull configuration, that was designed and built in France at the start of the millennium. It was intended to be homebuilt from kits, and a few prototypes were constructed, but development ended when the company went into receivership in 2006.
The CSIR SARA II is a South African two-seat experimental autogyro designed and built by the Aeronautics Research Unit of the Council for Scientific and Industrial Research.
The Ryson STP-1 Swallow is an American experimental two-seat powered cruising sailplane designed and built by the Ryson Aviation Corporation to be license built by other companies.
The Team Rocket F1 Rocket is a two-seat sport plane formerly built in Czech Republic and marketed as a kit for amateur construction by Team Rocket of Texas, United States. As of April 2017, the aircraft is being produced in the U.S. under license from Team Rocket by Frazier Aviation of Indiana.
The Voisin Triplanes were large experimental bombers built by Voisin in 1915 and 1916. After unsuccessful trials of the 1915 prototype a modified version with more powerful engines was built in 1916, as the Voisin E.28, but the type did not enter production.
The Velocity V-Twin is an American twin engined, homebuilt aircraft, designed by Velocity Aircraft and following the layout of their earlier Velocity XL but with a single vertical tail. It is the flagship model of the Velocity Aircraft Line.
The Pilatus PC-8D Twin Porter was a Swiss ten-seat light transport built by Pilatus Aircraft. The type did not go into production and only one was built.
The Payen Arbalète was a small, pusher configuration, experimental French tailless aircraft, designed by Nicolas Roland Payen, and first flown in 1965.
