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!
