With the DJI RC 2 Smart Controller, you can control your DJI drone. This advanced remote has a touchscreen that you can watch the footage of your drone on. This way, you don't need a smartphone to control your drone. The remote uses O4 video transmission technology. This is an improved version of OcuSync, which the DJI Air 3 works with. The remote has a larger and more stable range this way. The connection is less likely to fail.
