History:
Circa Reproductions of Surrey, British Colombia in Canada was a Company which produced plans to build 87 per cent scale World War I aircraft, the aircraft design being produced by Graham Lee of Lamont, Alberta. Leading Edge Air Foils, based at Peyton in Colorado, USA, for a time provided construction kits for the designs. Main design was been scale replica of the Nieuport 11, of which more than 400 have been produced, but other designs have also been available. These designs include the Nieuport 12, the Morane Saulnier N or Bullet, the Sopwith Tabloid and the Sopwith Baby. During World War I the Nieuport 11 was built, with some minor changes, by Siemens Schuckert in Germany as the D.1b.
The Nieuport 11 was the first of the Circa designs and was constructed from 6061-T6 aluminium tubing, with 2024-T3 aluminium gussets, held together by blind rivets. For a period welded steel tube fuselages were also available. The wings, tail and fuselage were covered with fabric. Main wheels were 61 cm (24 in) diameter spoked units with a bungee suspension and a tailwheel was usually installed in place of a skid. Engines recommended were the 30 kw (40 hp) Rotax 447, the Rotax 503, various conversions of the four-cylinder Volkswagen, and the Hirth.
The first Nieuport 11 scale replica was flown in July 1984 and undertook a short test program before being shown at the Experimental Aircraft Association convention at Oshkosh in Wisconsin that year. Kits became available to meet US ultralight regulations and Experimental amateur-built regulations. In the ultralight variant lighter materials were used to save weight.
Example have been completed in this region, one becoming ZK-WWI (c/n 234), described as a Circa Reproductions Nieuport 11 but finished and painted as a Siemens Schuckert D.1b. Another, described as a Siemens Schuckert D.16, was registered on 10 April 2006 as 10-4542 (c/n 3506/17) with Recreation Aviation Australia (RAA) but during early test flying at Albion Park, NSW was damaged and was placed in storage at The Oaks, NSW.
