If you want to use the DJI FPV Remote Controller, you must first reflash the Betaflight firmware. Make sure to enable “SBUS” protocol support when loading the firmware online. Next, import the default factory dump file into the CLI command line. Finally, adjust the Betaflight settings as needed. No hardware modifications to the flight controller are required.
