The aircraft is supplied as a kit for amateur construction.

Design and development

The ATF is a nanotrike intended for use as a motorglider, taking off under power and then shutting down the engine for soaring flight.

The aircraft was designed to comply with US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb. The aircraft has a standard empty weight of 186 lb. It features a minimalist design, 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 aircraft is made from bolted-together aluminum tubing, with its double-surface wing covered in Dacron sailcloth. Its 34.7 ft span Stratus XP wing is supported by cables and kingpost and is weight-shift controlled by an "A" frame control bar. The original wing offered by the manufacturer was the Stratos, but this was replaced by the improved Stratus XP in 2010. The Stratos XP features fiberglass wingtips, a different shaped sail providing a better glide ratio and lower sink rate. It is available in two sizes, 16 m2 and 17.5 m2.

The aircraft was originally powered by the 22 hp Zenoah G-25 single cylinder, two-stroke engine. Engines available in 2012 are the 26 hp Simonini Mini2, 30 hp Zanzottera MZ 34, 25 hp Vittorazi 185 and the 22 hp Bailey V4-200 powerplants.

The ATF can be folded up to 27" x 30" x 55" (69 x 76 x 140 cm) for storage or ground transport.
