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 hang glider-style high-wing, weight-shift controls, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.[1]

The Prowler's design goals included maximum cruise speed and to achieve this a wing of small area was selected. This results in an ultralight with a cruise speed of 57 mph (92 km/h), at the expense of a stall speed of 28 mph (45 km/h), the fastest stall speed permitted by FAR 103 category rules.[1][2]

The aircraft is made from bolted-together aluminum tubing, with its double-surface wing covered in Dacron sailcloth. Its 110 sq ft (10 m2) area wing is supported by a single tube-type kingpost and uses an "A" frame control bar. The standard engines supplied was the 40 hp (30 kW) Rotax 447 twin cylinder, two-stroke, air-cooled, single ignition aircraft engine. A cockpit fairing and wheel pants were factory options.[1]
