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.[1][2]
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 50 ft (15.2 m) 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.[1]
The aircraft was registered with the US Federal Aviation Administration in the Experimental - Amateur-built category. Only one was ever constructed.[2]
In 1974 it was reported that plans were underway to create a new 56 ft (17.1 m) span wing for the LM-1, that would feature a Wortmann airfoil.[1]
