The Arrow Coax Livella Uno ({{lang-en|italic=yes|First Level}}) is a German helicopter under development by Arrow Coax Ultra Light Helicopter of Hornhausen and introduced at the AERO Friedrichshafen airshow in 2015. The aircraft is intended to be supplied as a kit for amateur construction.[1]

Design and development

The Livella Uno was designed to comply with the US FAR 103 Ultralight Vehicles and the European 120 kg class ultralight aircraft rules. It features a dual coaxial main rotors, with an inverted V-tail, a single open-air pilot's seat without a windshield, tricycle landing gear and a {{convert|40|hp|kW|0|abbr=on}} Wankel Aixro XH40 engine.[1]

The aircraft fuselage is made from tubing. Its two-bladed rotors have a diameter of {{convert|3.8|m|ft|1|abbr=on}}. The aircraft has a typical empty weight of {{convert|85|kg|lb|0|abbr=on}} and a gross weight of {{convert|195|kg|lb|0|abbr=on}}, giving a useful load of {{convert|110|kg|lb|0|abbr=on}}.[1]

The aircraft mounts a Galaxy Rescue System ballistic parachute in the rotor mast. It also has a small electric motor to power the rotor system from a battery in the event of an engine failure, allowing five minutes of power to land, since the low inertia rotor blades may not support autorotation.[2]
