Rotortec GmbH is a German aircraft manufacturer based in Görisried, Allgäu.

The company was founded by Jochen Steinbeck and specializes in the design and manufacture of autogyros.

[1] The company's initial design was the Rotortec Cloud Dancer I, a single-seat, enclosed cockpit gyro, that uses an innovative electromagnetic clutch for the Carden Drive.

This was followed into production by the two-seats in side-by-side configuration Rotortec Cloud Dancer II, which was first shown at AERO Friedrichshafen in 2009.

The third design, the Rotortec Cloud Dancer Light, is a simplified version of the Cloud Dancer I, without a cockpit fairing and intended to qualify for the German 120 kg ultralight class as it has an empty weight of 120 kg (265 lb).
