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

[edit]

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]
