With this DJI Tello GameSir T1d controller you control your Tello drone easily and comfortably via your smartphone. Thanks to the 3D joysticks and extra buttons you can steer the drone accurately to any location. And you also make advanced movements, such as a 'tilt' where you aim the camera from the bottom up to reveal a landscape. You start your flight immediately because your controller is quickly connected to the GCM connection mode. The automatic sleep mode helps to save the battery.
