DJI's FPV Remote Controller was made for racing and freestyle pilots. The added switches give more configuration options than previous DJI remote controllers. The DJI Remote syncs perfectly with the DJI FPV Air Unit for seamless integration into your drone builds. With the DJI FPV Remote Controller, parameters of each component can be adjusted remotely. Purchasing the DJI FPV Goggles and the DJI FPV Air Unit eliminates the need of any additional receiver. Users can also enjoy 7ms ultra-low latency between the remote controller and the air unit. Note: Using the DJI FPV Remote Controller is optional with the DJI Digital HD FPV system. The DJI Remote Controller is useful if you want to use their built-in Tx system.
