Design and development

The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 252 lb (114 kg). It features a single main rotor, an enclosed cockpit with a windshield, skid-type landing gear and a twin cylinder, air-cooled, two-stroke, single-ignition 55 hp (41 kW) Hirth 2703 engine. [1] [3]

The aircraft fuselage fairing is made from composites. Its 21 ft (6.4 m) diameter main rotor employs an ATI 012 (VR-7 mod) airfoil at the blade root, becoming an ATI 008 (VR-7 mod) at the tip. The main and tail rotor blades are of honeycomb composite construction. The cyclic control is roof-mounted, hanging down into the cockpit, but is otherwise conventional. The 23 in (58.4 cm) diameter tail rotor features a shrouded tail rotor and a tailplane with end-fins. [1] [4]

When it was available, the aircraft could be purchased as a 150-hour assembly kit or as a 60-hour quick-build kit. No plans were available. [1] [2]
