NOVELTY - The set of a rotatable aerofoil drone, comprises an electronic navigational card (320), a support for fixing the electronic card in a housing formed in the drone, a fastener (301) for carrying a mechanical interface (310), a connecting leg (302) carrying the electronic navigational card and freely mounted at one end to the fastener, and a battery for supplying current to the drone. The support comprises a mechanical interface with the housing, and is constituted by a material absorbing mechanical vibrations. The mechanical interface is present in annular form.    USE - The set comprising an electronic navigational card is useful for a rotatable aerofoil drone (claimed), and in radio controlled toys used by children and as a piece in indoor environments including house or apartment.    ADVANTAGE - The set comprising an electronic navigational card reduces or eliminates the effects of vibration or noise generated by the propulsion system on the functioning of the navigation sensor, and prevents the loss of relevant information due to the low-pass filtering.    DETAILED DESCRIPTION - The set of a rotatable aerofoil drone, comprises an electronic navigational card (320), a support for fixing the electronic card in a housing formed in the drone, a fastener (301) for carrying a mechanical interface (310), a connecting leg (302) carrying the electronic navigational card and freely mounted at one end to the fastener, and a battery for supplying current to the drone. The support comprises a mechanical interface with the housing, and is constituted by a material absorbing mechanical vibrations. The mechanical interface is present in annular form, and connected on a corresponding annular shoulder fixed in the housing. The electronic navigation card comprises a navigation sensor (321) such as an accelerometer arranged on the card to be positioned at the baric center of the drone. The battery is fixed by Velcro (RTM: Fabric hook-and-loop fastener). The absorbent material is thermoset foam. The mechanical interface of absorbent material is fixed to the housing by an adhesive.
