to program a BetaFlight flight controller with your computer, you need
- the BetaFlight Configurator Chrome extension
- a good USB cable. If you can not connect, try a few different cables.
- a good firmware version. The website of your FC should state what you can install.
- a good set of settings, to match your firmware hardware and flying style
Install the firmware of your choice, using full chip erase.
Then apply the setting dump over the CLI (command line interface).
Bind. Go to receiver tab. Confirm receiver inputs.
