Where Does EdgeTX Store Models and Settings?
EdgeTX keeps radio models, mixes, and settings on the transmitter SD card under MODELS and RADIO folders. Back up the card before updating firmware.
Last updated
EdgeTX stores everything on the SD card in the radio. Model setups with mixes, curves, and logical switches live in MODELS, while global settings, themes, and sounds sit in RADIO. The firmware itself flashes to internal memory.
That makes the card the backup unit: duplicate it before every update and keep the spare with your flight box. Companion apps edit the same files on a computer for faster typing. Mismatched firmware and card contents cause the classic blank-model-list mystery. Label cards per model to avoid field mixups.

Frequently asked questions
How do I update EdgeTX safely?
Copy the SD card contents to a computer before flashing, then restore after verifying the new firmware boots. Models reference images and sounds by path, so partial restores break them. Keep one known-good card for flying days.
Can I copy models to another radio?
Yes with the same major version on both radios. Copy the model files to the new card and rebind receivers afterward. Switch assignments follow the model file; receiver numbers never transfer.
