Paraplane PSE 2 Osprey

Design and development

The PSE-2 Osprey 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 235 lb (107 kg). It features a Hi-Pro 370 sq ft (34 m²) parachute-style wing, single-place accommodation, tricycle landing gear and a single 50 hp (37 kW) Rotax 503 engine.

The aircraft carriage is built from aluminium tubing. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has foot pedal-controlled nosewheel steering. The main landing gear incorporates spring rod suspension.

The standard day, sea level, no wind, take off with a 50 hp (37 kW) engine is 200 ft (61 m) and the landing roll is 75 ft (23 m).

The manufacturer estimates the construction time from the supplied assembly kit as five hours.
