The Skye Treck Skyseeker is a Canadian ultralight aircraft that was designed and produced by Skye Treck of Manitoba. The aircraft was supplied as a kit for amateur construction.[1][2]
Design and development
The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 248 lb (112 kg). It features a cable-braced high-wing, a single-seat, open cockpit, conventional landing gear and a single engine in pusher configuration.[1][2]
The aircraft is made from bolted-together aluminium tubing, with the flying surfaces covered in Dacron sailcloth. Its single-surface 32 ft (9.8 m) span wing's cable bracing is supported by a single kingpost. The pilot is accommodated on an open seat, without a windshield. The landing gear features bungee suspension on all three wheels and the tail wheel is steerable. No brakes are fitted. The standard engine supplied was the single cylinder two-stroke Rotax 277 of 28 hp (21 kW) and it is mounted on the wing trailing edge, with the propeller turning in between the tail boom tubes. The engine utilizes a 2:1 belt reduction drive with a centrifugal clutch to allow the propeller to stop when the engine is at idle.[1][2]
The Skyseeker sold in very large numbers in the 1980s in Canada.[1]
