By February 2018, the aircraft was no longer offered for sale on the company website, although a trike wing with the same name was still in production.[2]
The Solairus was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 2540NaN0. The aircraft has a standard empty weight of 2540NaN0.[1]
The aircraft design features a strut-braced topless hang glider-style high-wing, weight-shift controls, a single-seat open cockpit with a cockpit fairing, tricycle landing gear with wheel fairings and a single engine in pusher configuration.[1]
The aircraft wing is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. The trike carriage is of composite materials and is an aerodynamically faired design. Its 34.681NaN1 span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. The powerplant is a single-cylinder, air-cooled, two-stroke 210NaN0 Polini Thor 100, 290NaN0 Polini Thor 200 engine or the 220NaN0 Bailey 200 V4.[1]
The aircraft has a carriage weight of 1080NaN0 and an empty weight of 2540NaN0.[1]
