The Striplin Lone Ranger is a family of American ultralight aircraft that was designed by Ken Striplin. The aircraft was supplied as a kit for amateur construction.[1][2]

Design and development[edit]

The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 245 lb (111 kg). It features a high-wing, a single-seat, open cockpit, tricycle landing gear and a single engine in tractor configuration.[1]

The Lone Ranger was designed to overcome pitch stability problems found in the earlier Striplin F.L.A.C. flying wing. Stability was increased with the addition of a conventional tail unit, including conventional elevators and a rudder for control. Because they were no longer needed the F.L.A.C.'s wing tip rudders were deleted. The landing gear is of tricycle configuration and features a steerable nosewheel. The engine is mounted above the wing, with the propeller above and in front of the windshield. The design spawned a family of variants featuring one and two seats, as well as strut-braced and cantilever wings.[1]
