SDB Karat

[1][2] The Karat is a nanotrike that was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg).

[1] The aircraft is made from bolted-together aluminum tubing, with its single or double surface wing covered in Dacron sailcloth.

A typical wing used would have a 9.8 m (32.2 ft) span, be supported by a single tube-type kingpost and use an "A" frame weight-shift control bar.

The standard powerplant is a single cylinder, air-cooled, two-stroke, 28 hp (21 kW) Hirth F33 engine.

[1] When it was available the trike was sold as a fuselage frame and engine, with the customer providing the hang glider wing.
