An unmanned aerial vehicle (UAV) controller may have control elements configured to receive inputs from a user. A cover may be coupled to the controller. The cover may be movable between a closed position in which the control elements are covered and an open position in which the control elements are exposed. An antenna may be integrated in the cover. The antenna may be electrically connected to circuitry in the controller for communicating with a UAV. In some implementations, a conductive plane and/or an insulating plane may be integrated in the cover. In some implementations, a heatsink, a fan, and/or a support mechanism may be arranged on an under portion of the controller. In some implementations, a circuit board including a cutout may be arranged inside the controller.
