Rotec Panther

Design and development

The aircraft was originally designed as a homebuilt aircraft, but was later lightened and adapted to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). In its ultralight version the aircraft has a standard empty weight of 250 lb (113 kg) when equipped with a lightweight engine and an abbreviated cockpit fairing. It features a strut-braced high-wing, a single-seat, enclosed cockpit, conventional landing gear and a single engine in pusher configuration.

The aircraft is made from aluminum tubing, with the flying surfaces covered in Dacron sailcloth. The cockpit fairing is made from fiberglass. Its 34 ft (10.4 m) span wing is supported by "V" lift struts and jury struts and features elliptical winglets. The controls are conventional and feature full-span ailerons. The landing gear has bungee suspension and optional main wheel fairings.
