Design and development[]

The A3C was designed to comply with amateur-built aircraft rules. It features a single main rotor, a two-seat side-by-side configuration enclosed cockpit with a windshield, tricycle landing gear and a four cylinder, air and liquid-cooled, four-stroke, dual-ignition, turbocharged 115 hp (86 kW) Rotax 914 or a normally-aspirated 100 hp (75 kW) Rotax 912S engine mounted in pusher configuration.

Air Copter is well-known as a designer and manufacturer of gyroplane rotor blades and other dynamic components and they also make their own components for the A3C. The aircraft's 8.40 m (27.6 ft) diameter rotor has a chord of 20 cm (7.9 in) and employs a NACA 8H12 airfoil. The main rotor has a pre-rotator to shorten take-off distance. The aircraft has an empty weight of 250 kg (550 lb) and a gross weight of 450 kg (990 lb), giving a useful load of 200 kg (440 lb).
