Because it is a mere 100 pounds, there is no debate that the Birdman TL-1 is an ultralight craft. In an effort to emphasize ease of construction and light weight, an unusual heat-shrink-to-fit synthetic mylar skin, Monokote, is used to cover the wood and foam-reinforced wings. The fuselage is a standard plywood monocoque, and the tail section is a V-type. While the main gear is attached underneath the wing, the pilot’s legs and feet take the place of a nose wheel.
