The Calidus features a single main rotor, a two-seats in tandem enclosed cockpit with a complete aerodynamic cockpit fairing, tricycle landing gear with wheel pants and a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 100 hp (75 kW) Rotax 912 engine or turbocharged 115 hp (86 kW) Rotax 914 engine in pusher configuration.

The aircraft fuselage is made from composites and is a faired teardrop shape to ensure smooth airflow over the variable pitch pusher propeller.
Its 8.4 m (27.6 ft) diameter rotor has a chord of 20 cm (7.9 in).
The aircraft has an empty weight of 265 kg (584 lb) and a gross weight of 450 kg (990 lb), giving a useful load of 185 kg (408 lb).
The design incorporates vibration dampers that greatly reduce the level of main rotor vibration transmitted to the cockpit.

The design is noted for both its cruise speed of 160 km/h (99 mph) and range of 800 km (500 mi).
It was developed into the side-by-side configuration AutoGyro Cavalon.
