Design and development

Based on the enclosed cockpit Rotortec Cloud Dancer I, the Cloud Dancer Light was designed as a lower cost model for the German 120 kg ultralight class. It features a single two-bladed rotor, a single-seat open cockpit without a windshield, tricycle landing gear with wheel pants and a twin cylinder, liquid-cooled 70 hp (52 kW) Hirth 3503 two stroke engine mounted in pusher configuration.[1]

The aircraft fuselage frame is made from aluminum, while the tail is Kevlar composites. Its 7.10 m (23.3 ft) diameter rotor has a chord of 17.5 cm (6.9 in). The instrument panel is mounted in a simple pod. The aircraft has an empty weight of 120 kg (265 lb) and a gross weight of 300 kg (661 lb), giving a useful load of 180 kg (397 lb).[1]
