The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 2540NaN0. The aircraft has a standard empty weight of 2480NaN0. 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.
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 570NaN0, at the expense of a stall speed of 280NaN0, the fastest stall speed permitted by FAR 103 category rules.[2]
The aircraft is made from bolted-together aluminum tubing, with its double-surface wing covered in Dacron sailcloth. Its 110square feet area wing is supported by a single tube-type kingpost and uses an "A" frame control bar. The standard engines supplied was the 400NaN0 Rotax 447 twin cylinder, two-stroke, air-cooled, single ignition aircraft engine. A cockpit fairing and wheel pants were factory options.
