The Z-120 was designed to comply with the German 120 kg class rules, hence its designation. It features a cantilever high-wing, a single-seat, an enclosed cabin accessed by open doorways, fixed conventional landing gear and a single engine in tractor configuration.[1]
The aircraft is made from special thin-gauge sheet aluminum for lightness. Its 7.451NaN1 span wing has an area of 9.6m2 and lacks flaps. The standard engine used is a 350NaN0 Woelfe Aixro XF40 single-rotor Wankel engine.[1]
