The invention relates to a remote control flying machine, in particular a remote control ultralight helicopter, with at least one rotor blade (104), the pitch (.alpha.) of which may be adjusted. According to the invention, the adjustment of the pitch (.alpha.) of the at least one rotor blade is achieved by means of a force, in particular a torsion force directly applied to the rotation axis of the rotor blade. Said force is generated by a magnetic field, variable by the electrical control of at least one coil (196) which is not part of an electric motor.
L'invention concerne un aéronef télécommandable, en particulier un hélicoptère ultra léger télécommandable, comprenant au moins une pale (104) de rotor à angle d'incidence (.alpha.) réglable. Selon la présente invention, le réglage de l'angle d'incidence (.alpha.) de la pale (104) du rotor s'effectue par l'intermédiaire d'une force, en particulier une force de torsion directement appliquée sur l'axe de rotation de la pale du rotor. Cette force de torsion est générée par un champ magnétique, variable par l'excitation électrique d'au moins une bobine (196) n'entrant pas dans la constitution d'un électromoteur.
