The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.
[1] The LO-120 was designed to comply with the Fédération Aéronautique Internationale microlight rules.
It features a cantilever high-wing, a two-seats-in-tandem open cockpit with a small windshield, fixed tricycle landing gear and a single engine in pusher configuration.
Its 15.5 m (50.9 ft) span soaring wing has an area of 16 m2 (170 sq ft) and can be quickly swapped for an alternate, reduced span microlight touring wing that increases cruising speed.
The standard engine is the 40 hp (30 kW) Rotax 447 two-stroke powerplant.
