	It doesn't much look like it, but in fact the Cavalier SA102.5 is a redesign of the Gardan Minicab (pictured under private aircraft, France). The modifications include a tricycle undercarriage, swept tail fin, revised canopy and, in this example, long range fuel tanks on the wing tips. The design was done by Canadian company K & S Aircraft Supply, who set up a company with the bizarre name of Squaircraft to market plans to home builders. A two seater, it is 18 feet 4 inches ling, with wing span of 27 feet 8 inches and maximum weight of 1,650lb. Its Lycoming O-235 engine gives it a cruising speed of 140mph. This one first flew in 1976, and was pictured at Sunderland in February 1979. It was still airworthy in 2005.
	The Christen Eagle is a powerful aerobatic biplane designed by Frank Christensen and loosely based on the Pitts Special, with which it is easily confused on casual inspection. It is a kit built aircraft, with kits marketed by Aviat (www.aviataircraft.com). Construction is a mixture of metal tube, wood and fabric. It is a two seater, powered by a 200hp Lycoming AEIO-360 engine, whcih gives it a 185mph top speed and range of 350 miles. It is 18 feet 6 inches long and spans 19 feet 11 inches, and has a gross weight of 1,600lb. Since its first flight in 1977, over 1,000 kits have been sold. It is very popular with people who want a potent and capable aerobatic machine. Elstree, October 1982
	The Coates Swalesong SA2 is a one-off design by Jim Coates. It is of wooden construction, and first flew in 1973. It is a stylish, low wing two seater, powered by a 90hp Continental engine. Wing span is 26 feet 5 inches; length, 19 feet. Maximum gross weight, 1,150lb. It cruises at 110mph over a range of 450 miles. It was pictured at Rush Green, in June 1980
	The Corby CJ1 Starlet was designed in Australia by John Corby. The type has existed since at least 1973. It is a small single seater, maximum weight 710lb, normally powered by a 1.6 litre VW engine, though almost anything up to 75hp will do. It has decent handling characteristics and is aerobatic. It is popular in the Southern hemisphere; five are active in the UK. Turweston, July 2005
	The bizarre Croses LC-6 Criquet 22 was designed by French designer Emilien Croses, and is based on the layout of the pre-war Mignet Pou-du-Ciel (Flying Flea). It is technically a tandem wing machine, the two wings being of unequal span: the front wing spans 25 feet 4 inches and the rear, 22 feet 9 inches. Although only 15 feet long, it is a two seater, with gross weight of 1,210lb. It can be powered by a variety of engines, such as the 90hp Continental, with which it has a cruising speed of 110mph. Construction is wood and fabric; it first flew in July 1965. This one was at Cranfield, July 1983
	The Currie Wot was designed by Mr J.R. Currie, a lecturer at the Chelsea College of Aeronautical Engineering, in 1937. Two were built simultaneously at Lympne, the first of which flew in 1937. Plans were made available shortly after the war, with the first being completed at Southampton by J.O. Isaacs (later to design the Isaacs Fury). Its simple wood and fabric construction made it a popular choice for homebuilders in the 1960s and 70s. Many have been completed, with a wide variety of engine installations. At the time of writing (October 2005), there are sixteen Wots flying in Britain. Its superficial resemblance to the SE5A has led several to be camouflaged and used in films about the First World War. Wing span is 22 feet, 1 inch; length, 18 feet 3 inches (depending on engine); maximum weight, 900lb; top speed 95mph. This one, pictured at Cranfield in July 1988, is powered by a 65hp Walter Micron III engine.
	The Davis DA-2 is unusual in having a V-tail, making it look a bit like a little homebuilt kit Bonanza. It is an American design of all metal construction, and can be powered by a variety of engines from 65 to 100hp. Cruising speed is up to 125mph and it has a range of about 400 miles. It is a two seater, with maximum gross weight of 1,250lb. It is 17 feet 10 inches long, with a wing span of 19 feet 2 inches. This one was at Cranfield, date uncertain.
	The Denney Kitfox is a popular little kitplane of which several thousand kits have been sold since it first appeared in 1984. It is marketed by Sport Plane LLC (www.sportplanellc.com). Its Rotax 532 engine gives it a sedate cruising speed of 85mph. It is a two seater, 21 feet 7 inches long, with a wing span of 32 feet. Gross weight is 950lb. Photograph by Ivy, Kemble, July 2005
	The Duruble RD03 Edelweiss is an ambitious design by Frenchman M Roland Duruble. It is a four seat homebuilt design with retractable undercarriage. Of all metal construction, it is powered by a 150hp Lycoming engine. Cruising speed is 155mph and range over 600 miles. It is strange that this highly capable design has not proved more popular since it first flew in 1982. This is the first one to fly, which visited Cranfield in July 1984.
	The DynAero MCR-01 Ban-Bi is a very smart little ultralight kit aircraft, of composite construction. Kits are marketed by DynAero (www.dynaero.com). It is normally powered by a 100hp Rotax 912 engine, which gives is a top speed of 190mph and range of 850 miles. Since this dainty little two seater first flew in July 1996, it has become increasingly popular, especially since it offers excellent performance in the ultralight category: gross weight is 1,080lb. Ban-Bis seem to attract interesting registrations! Top: Old Buckenham, June 2005. Bottom: Kemble, July 2005.
	The DynAero MCR-4S is a four seat development of the DynAero range. The most unusual thing about it is the ratio of empty weight to payload: gross weight is 1,650lb, of which 880 lb (well over half) is useful load - like petrol, passengers and a bit of luggage. That ratio must be pretty hard to beat for a machine in this class. Its 100hp Rotax engine gives it a top speed of 150mph (it's heavier than the Ban-Bi), but range is a healthy 1,150 miles. It first flew in June 2000. This one was at Kemble, July 2005
	The Dynamic is another new generation composite ultralight, in this case a Czech design marketed by the Yeoman Light Aircraft Company (www.ylac.bluecube.cz). Powered by a Rotax 912 engine of up to 100hp, if has a cruising speed of 140mph and range of 745 miles. Gross weight is 990lb. Over 100 of this very new design have been built to date. This one was also at Kemble in July 2005
