The Betaflight and iNAV setup guides — the ones behind the Setup help link on each External FC card — were English-only, and stayed English even after you switched the app language. Both are now fully translated into Ukrainian and Simplified Chinese.
They follow the app language. Change it in Settings → General and an open guide re-renders in place. No restart.
Translated in full, not just the headings:
- The troubleshooting tables
- The remote-SITL and WSL2 networking sections
- The Betaflight motor-order and SITL-bridge notes
Commands, file paths, build targets and CLI settings are left exactly as you have to type them — only the prose around them is translated.
