__NOTOC__ The Kreider-Reisner KR-21-A was a 1928 American two-seat monoplane. They were designed and built by the Kreider-Reisner Aircraft Company of Hagerstown, Maryland. Fairchild Aircraft took over Kreider-Reisner in 1929 and continued to build them, as the Fairchild KR-21, later the Fairchild 21.〔〔 ==Design and development== The KR-21-A was a low-wing braced monoplane with two open tandem cockpits and powered by an 80 hp (60 kW) Armstrong Siddeley Genet radial piston engine.〔 It was of mixed construction and had a fixed tailwheel landing gear and was fitted with dual controls.〔 The KR-21-B was a more powerful biplane development, using a 125 bhp Kinner B-5 engine.〔 Five were produced, three built as -B models and two converted from the -A. At least three, most of the production, survive today * NC107M * NC236V * NC954V〔 The KR-21 would in turn form the basis of the KR-22 parasol-wing monoplane design. 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「Fairchild 21」の詳細全文を読む スポンサード リンク
