EdgeTX Companion, on a phone

EdgeTX Companion is the official desktop tool for Windows, macOS and Linux, and it is excellent for building models at a desk and simulating them. There is no Companion for Android. FlySpark fills that gap for the jobs you need at the field or away from your computer: tweak a mix, fix a switch, back up the card before a firmware update.

Models are read and written in EdgeTX's own YAML files on the SD card, so the radio and Companion still see the same models afterwards.

What you need

An Android phone with USB OTG support and a cable that fits your radio. On the radio, choose USB Storage (SD card) when you plug it in. For firmware, start the radio in its bootloader. The iPhone cannot reach USB storage devices from apps in this way, so these tools are not in the iPhone app.

Always back up the SD card before changing firmware or models.

How to back up an EdgeTX radio with an Android phone

1. Install the app. Install FlySpark from Google Play.
2. Plug in the radio. Connect the radio with a USB OTG cable and choose USB Storage on the radio's screen.
3. Open EdgeTX. Open EdgeTX radio in FlySpark and allow access to the SD card.
4. Back up. Open the backup tab and save a copy of the card to your phone.

Frequently asked questions

Is there EdgeTX Companion for Android?

Not officially. FlySpark's Android app covers model editing, SD card backup and restore, Lua scripts and firmware flashing over USB.

Does it work on iPhone?

No. The EdgeTX tools need USB access that the iPhone does not give apps. The browser demo works on any device.

Which radios are supported?

Radios running EdgeTX that offer USB Storage mode, such as models from RadioMaster, Jumper and others.

Can I edit models without a radio?

You can explore the sample SD card in the demo. Real edits need the radio connected.
