A drone comprising a plurality of hollow struts (Fig. 1, 16a – 16f), which extend from the body of the drone, each comprising a motor (Fig. 2, 18a – 18f) for driving a propeller (Fig. 2, 17a – 17f) and a fan. The fan draws air down the hollow struts in order to cool the components within the body. The fan may be located at the end of the strut nearest the drone body, such that the fan draws air from an inlet and exhausts it through the end of the strut further from the drone body. Inlet includes a cowl to prevent the ingress of rainwater. A drone body comprising electrical circuitry and a fan in order to cool the components, driving exhaust air from a vent port. The components of the drone may have a heat sink, possibly including a fin, and the fans may be positioned so as to force air over the heat sink. The drone may include: image capture and image transmitter for a remote receiver; air quality monitor and signal transmitter; a tether for the drone, which comprises a winch, and may be used to receive an electrical current.
