Like the Bug it is intended to be an inexpensive and easy-to-fly three-axis-controlled aircraft similar to a primary glider, although the designer terms it an airchair.

The Goat has an empty weight of under 155 lb (70 kg) and so qualifies to be flown under the United States FAR 103 Ultralight Vehicles regulations and does not require registration or a pilot license.

Sandlin makes his computer assisted design drawings available free of charge as downloads in .dxf, .dwf and .gif formats and has explicitly released them to the public domain.

[1][2][3][4] The aircraft is predominately made from bolted-together aluminium tube and covered with heat-shrunk Dacron fabric.

[1][2][3] The Goat is designed to be launched by aerotow behind an ultralight aircraft, auto-tow, winch-launch or by rolling it down a slope.
