Unmanned Aerial Vehicles (UAVs) have been researched as a means of collecting information during disasters. Among them, VTOL UAVs that are called Quadrotor, have been attracting attention. A Quadrotor has a superior maneuverability than other UAVs. However, it is inferior to fixed-wing type UAVs in flying speed and cruising range. When UAVs are used for extensive disasters such as earthquakes, it needs to collect widespread information．Therefore, this research is aimed at developing a Quadrotor that can realize high-speed flight and wide cruising range by mounting a tilt system on the rotors in the conventional Quadrotor. This paper presents the overview of the new Quadrotor suggested in this study and describes the production of a tilt system attached to the conventional Quadrotor. Then, some experiments are conducted to check the fundamental operation of the tilt system. In addition, the overview of the PD control is also described for the speed control of a DC motor.
