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.

[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.
