Birdman TL-1
From Wikipedia, the free encyclopedia
The Birdman TL-1 was an extremely minimalist aircraft sold in kit form in the United States in the mid-1970s for US$1,395.[1]
Design and development
The TL-1's fuselage is nothing more than a boom connecting a set of wings with a V-tail. The pilot's seat and a pedestal carrying the pusher engine are attached to the top of the boom just forward of the wing. Flight control is provided by a series of spoilers.[2]
Construction is of wood covered with Monokote and the aircraft was designed to be quickly dismantled for transport or storage.[2] With an empty weight of 122 lb (55 kg), it is held to be the lightest aircraft to have been flown at the time.[citation needed]
