The Leffler-MacFarlane LM-1 is an American mid-wing, single-seat, FAI Open Class glider that was designed and constructed by Al Leffler, Walt MacFarlane and Bill Meyer, first flying in November 1963.〔Rogers, Bennett: ''1974 Sailplane Directory, Soaring Magazine'', page 45. Soaring Society of America, August 1974. USPS 499-920〕 ==Design and development== The LM-1 was built using a modified wing from a Laister-Kauffman TG-4. The wing retains its original wood and doped aircraft fabric construction, its span as well as the use of a NACA 4418 airfoil at the wing root, transitioning to a NACA 4409 at the wing tip. The newly designed fuselage is made from welded steel tube and fiberglass. The landing gear was originally a retractable dual-wheel hydraulic arrangement, that was replaced with a more conventional retractable monowheel from a Schreder HP-14.〔 The aircraft was registered with the US Federal Aviation Administration in the ''Experimental - Amateur-built'' category. Only one was ever constructed.〔 In 1974 it was reported that plans were underway to create a new span wing for the LM-1, that would feature a Wortmann airfoil.〔
