The Marske XM-1 was an American mid-wing, single-seat, experimental tailless glider that was designed and built by Jim Marske in 1957. Experimentation with the XM-1 lead to the final configuration of the later Marske Pioneer.〔 ==Design and development== The first of Marske's flying wings was the XM-1, a design inspired by the flying wing designs of Charles Fauvel and Al Backstrom. He built the XM-1 when he was 19 years old. The aircraft went though several versions, each a modification of the same basic airframe as Marske experimented with configurations. The aircraft started off with fins on the wing tips and was later converted to a single fin at the rear of the short fuselage in its "XM-1D" configuration.〔〔 The XM-1 was built with a welded steel tube fuselage covered in fiberglass. The wing was fabricated from wood and covered with doped aircraft fabric. The wing employed a 14% Fauvel airfoil. The landing gear was a fixed monowheel.〔 Only one XM-1 was built. It was registered with the US Federal Aviation Administration in the ''Experimental - Amateur-built'' category.〔〔 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「Marske XM-1」の詳細全文を読む スポンサード リンク
