## Flight Controller Firmware (Betaflight)

This is the operating system of your FPV drone.

{% hint style="warning" %}
Generally, if the drone flies well, do NOT upgrade the firmware version. New firmware versions often require completely different PID tuning. Upgrading without re-tuning may cause the drone to fly poorly or overheat.

GEPRC Pro Tip: Regarding Firmware Upgrades

Many beginners feel the urge to always update Betaflight to the absolute latest version (e.g., from 4.3 to 4.5). Please be warned: flashing new Betaflight firmware **wipes all GEPRC factory presets!** If you absolutely must upgrade, type `diff all` in the CLI and save a backup first. You will need to manually migrate your settings back.

Conclusion: For most pilots, Factory Firmware is the Best Firmware. Don't change it unless you have to!
