Design and development

The Zephyr was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear, a T-tail and a single engine in tractor configuration.

The aircraft's fuselage is made from composites with wooden bulkheads. The semi-tapered 9.6 m (31.5 ft) span wing is made from plywood with composite spars and leading edges and employs a UA-2 airfoil. The wing is covered with doped aircraft fabric. The standard engine factory-supplied was the 100 hp (75 kW) Rotax 912ULS four-stroke powerplant.

The Zephyr is noted for its low payload. With a useful load of 197.5 kg (435 lb) and full fuel of 43 kg (95 lb), this leaves only 154.3 kg (340 lb) for occupants and baggage.

The Zephyr was later developed into the ATEC 321 Faeta.
