Design and development
editThe 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 7.45 m (24.4 ft) span wing has an area of 9.6 m2 (103 sq ft) and lacks flaps. The standard engine used is a 35 hp (26 kW) Woelfe Aixro XF40 single-rotor Wankel engine.[1]
