The Faeta was designed to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft 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. It is an approved SLSA in the USA.[2][3][4][5]

The aircraft fuselage is made with a carbon fibre shell and composite sandwich bulkheads. The 9.6 m (31.5 ft) span wing is made from carbon fibre sandwiches built upon a laminated wooden spar. The wing varies from the Zephyr in that it has a different tapered planform and uses a new airfoil. The design attempts to provide a lower empty weight and stall speed than the 122 Zephyr. The standard engine available is the 100 hp (75 kW)Rotax 912ULSfour-stroke powerplant.[2][3][4]

The Nordic Omsider amphibian prototype uses the wings and part of the tail from the Faeta.[4]
