Birdman Atlas
The Birdman Atlas is a single-seat, high wing, single engine in pusher configuration, ultralight aircraft that was based upon the Eipper Quicksilver design.[1][2]
Development
The Atlas was introduced to the marketplace in 1980. Production was curtailed in about 1983 as the company concentrated on producing the newer Birdman WT-11 Chinook instead.[1]
The Atlas was a development of the Quicksilver and as such incorporated many of the Quicksilver's features, such as a 6061-T6 aluminum-framed, single-surface Dacron-covered, wire-braced high wing, with the ground wires suspended from a kingpost. The fuselage structure was also built from 6061-T6 aluminum tube.[2]
The early Atlas XC variants used weight shift for control supplemented with a rudder, whereas the later 3-A versions (for 3-Axis) utilized a conventional control system with elevator and rudder, and spoilers for roll control.[2]
