About the Calidus

The Rotorsport UK Calidus is a type-certificated two-seat gyrocopter featuring a single pusher engine and a single main rotor. Built with an enclosed composite tandem cockpit and tricycle landing gear, the aircraft suits recreational and sport flying.

Designed and originally produced in Germany, the type was later approved and modified for the United Kingdom market. The airframe incorporates specialized vibration dampers to reduce rotor feedback in the cabin and features a faired teardrop fuselage shape that optimizes airflow over the propeller. Examples have been registered in multiple countries under experimental and special categories.
