RotorSport UK Calidus
The RotorSport Calidus is a German tandem two-seater autogyro modified in the UK to meet British Civil Airworthiness Requirements CAP643 Section T.[1][2] The Calidus is an enclosed-cockpit development of the open-cockpit RotorSport UK MT-03. New-build AutoGyro Calidus aircraft are imported from the manufacturers, AutoGyro GmbH in Hildeshem, Germany and completed to British regulations by RotorSport UK Ltd.[2]

Design and development
The Calidus is powered by a 100 hp (75 kW) Rotax 912 ULS, although optionally a 115 hp (86 kW) Rotax 914 UL Turbo can be fitted. Fuel capacity is either 39 litres in a single tank or 74 litres in two tanks.[2] The Calidus has an aerodynamic fuselage pod, giving 20 knots higher maximum speed than the MT-03.[3][4] While the open-cockpit MT-03 (which continues in production) is promoted as a "motorbike in the skies", the Calidus is aimed at a different market. The Calidus' fully enclosed cockpit protects the occupants from exposure to inclement weather, while the aircraft's higher cruise speed makes it more suitable for long-distance touring.
The panel can be equipped with conventional instruments and/or a "glass panel" according to certification requirements and the buyer's needs. For the UK RotorSport version, either a fixed-pitch propeller or a ground-adjustable propeller may be fitted;[2][5] but in Germany the unmodified AutoGyro Calidus has either a ground-adjustable propeller or an inflight-adjustable controllable-pitch propeller.[2][5]
The Calidus has a take off distance of 10 to 70 metres and lands in 15 metres, or can land vertically in some circumstances.[5] Flying speeds range from 20 mph (32 km/h) to 120 mph (193 km/h);.[5] An optional heater makes cold-weather flying feasible; but although navigation lights may be fitted, night flying is not permitted. The payload is 230 kg for versions with the Rotax 912,[2] so even with a full fuel load of 54 kg, two crew of up to 88 kg each can be accommodated.
