Rotor arrangement for model or micro helicopter has main rotor with further drive rotors connected rigidly or vertically adjustable for fixing immovable anywhere along relevant motor on drive sleeve

摘要

The rotor arrangement has a main rotor (6) and control units (A,B,C) or further drive rotors which have rotor-integral drive sleeves (7,11). The main rotor or other drive rotors can be connected rigidly or vertically adjustable so that they can be fixed immovable anywhere along the relevant motor (8) on the drive sleeve. The rotors of the control unit are offset outwards axially concentric so that they are no longer affected aerodynamically by the air throughput of the main rotor whereby all the rotors can also lie in one plane or in a plane above the main rotor.
