The Bushcaddy R-80 is a Canadian ultralight and light-sport aircraft that was designed by Jean Eudes Potvin of Lac Saint-Jean, Quebec in 1994 and produced by his company Club Aeronautique Delisle Incorporated (CADI). It was later built by Canadian Light Aircraft Sales and Service (CLASS) of St. Lazare, Quebec and later Les Cedres, Quebec and now Bushcaddy of Lachute, Quebec.〔Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 35.

ISSN 0891-1851〕 The R-80 designation indicates that the aircraft was originally designed for a Rotax engine of .〔 The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.〔〔〔 ==Design and development== The aircraft was designed to comply with the Canadian advanced ultralight rules and is also an approved US light-sport aircraft. It features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear or conventional landing gear and a single engine in tractor configuration.〔 The aircraft is made from 6061-T6 aluminum sheet over a cage of welded aluminum square 6061-T6 aluminum tube. The tail boom is conventional semi-monocoque construction. The non-tapered planform wings have 6061-T6 ribs and spars and employ a NACA 4413 (mod) airfoil. The airfoil modification removes the undercamber on the bottom of the wing, which makes construction easier, without giving up low speed performance. The aircraft's structure uses 2024-T3 aluminium for critical parts where extra strength is required, such as the spar, float and strut attachments as well as other critical components like the rudder horns. The R-80's structure is covered with 6061-T6 sheet of varying thicknesses; wing bottom skins are inches thick while the top is inches. The wings are supported by conventional "V" struts. 6061-T6 is predominantly used for its lower cost and also its better corrosion resistance, since many R-80s are flown on floats. Its span wing has an area of and does not fit flaps.〔〔〔 Standard engines used on the R-80 include the Rotax 912UL and the Rotax 912ULS four-stroke powerplants. The turbocharged Rotax 914 has also been fitted. The aircraft can also be mounted on floats and skis. Controls include a central "Y" control stick.〔〔〔 Construction time for the R-80 from the factory kit is 1,200 hours.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bushcaddy R-80」の詳細全文を読む スポンサード リンク
