It was introduced at the 2011 Aero show in Friedrichshafen. The aircraft is supplied as a complete ready-to-fly-aircraft. The Cavalon is a two-seats-in-side-by-side configuration development of the tandem-seating AutoGyro Calidus. It features a single main rotor, an 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 or 135 hp (101 kW) Rotax 915iS 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 a gross weight of 450 kg (990 lb). The design incorporates vibration dampers that greatly reduce the level of main rotor vibration transmitted to the cockpit. The design was developed into the AutoGyro eCavalon electric aircraft in 2013. By October 2019, 50 examples had been registered in the United States with the Federal Aviation Administration, all of them in the Experimental - Amateur-built category.
