This 2020 video introduces the Android preview version of Betaflight Configurator: The Betaflight team used Cordova to package the desktop configurator into an APK, so that mobile phones that support USB OTG/Host can connect to the flight controller through a data cable to view and modify the configuration in the field. It is suitable for diagnosis and small-scale adjustment, but before connecting, you must remove the propellers, keep the disarm, and confirm that the current Configurator is compatible with the flight control firmware.
How the Android version connects to a flight controller
A phone connected to a computer normally acts as a USB device. OTG/USB Host lets the phone act as the host and enumerate an external flight controller just as it would a USB drive. You need an Android phone with OTG support, a reliable OTG adapter and data cable, and must grant the app access to the correct USB device in the system prompt.
The app in the video resembles the desktop Configurator of that period and offers a mobile-screen layout option. Phone size, Android USB drivers, and available power affect the experience. Being able to install the APK does not guarantee that every flight controller will be detected. Test the connection at home with propellers removed instead of trying it for the first time at a race.
Safety limits for field tuning
Remove the propellers before any connection, CLI use, or configuration change. Keep the aircraft disarmed and place it securely away from people. Do not adjust settings while looking at your phone in a takeoff area, beside spectators, or with a connected battery in a state where accidental arming is possible.
First save diff/all, the flight-controller target, firmware version, and a known flyable baseline. Change only one parameter that you understand at a time. After saving and rebooting, reconnect and verify the value, then check the receiver, modes, motor directions, and failsafe without propellers. Only then proceed to a low-risk test flight.
Obtain APKs only from current trusted release sources
The video searches for Betaflight Configurator on GitHub, opens Releases, expands Assets, and selects the Android APK among the Linux, Windows, and other assets. It was still a Preview at recording. The old download page and Baidu Drive mirror in the description may now be outdated or replaced.
Today, first confirm that Betaflight still offers a supported Android build. Download it from the project’s current official repository or a trusted app store, and verify the version, publisher, signature, or checksum. Do not turn off ongoing security protection to install an unknown mirror, or grant permissions unrelated to USB configuration.
Version compatibility matters more than a familiar interface
Configurator looking like the desktop version does not mean it can safely manage every Betaflight firmware version. Fields, CLI behavior, firmware flashing, and target support change over time. An old Configurator with new firmware, or the reverse, can hide options or write incorrect values.
Use field tools mainly to inspect status, restore a known configuration, and make small changes. Firmware upgrades, target migrations, and extensive presets are better handled with a stable computer, power supply, backups, and recovery tools than rushed on a phone just before takeoff.
Operation steps
- Prepare at home with the propellers removed
Save diff/all, the target, and firmware version, and confirm that the phone supports OTG/USB Host.
- Connect the flight controller with OTG and a data cable
Keep the aircraft disarmed, grant the APK access to the correct USB device, and check connection stability.
- Verify the APK against the current official release source
Use only a currently supported GitHub Release or trusted app-store version, not an old mirror from the video.
- Match Configurator to the firmware
Check release notes and the compatibility matrix to avoid writing settings to new firmware with an incompatible old app.
- Make one clearly understood adjustment at a time
Save, reboot, read the settings back, and record the change. Do not work near people or in a state where accidental arming is possible.
- Recheck without propellers before a short test flight
Check the receiver, modes, motor directions, and failsafe. Refit propellers for flight testing only after confirming everything is correct.
FAQ
Can any Android phone connect to a Betaflight flight controller?
There is no guarantee. The phone must support OTG/USB Host, the cables must carry data, and the Android drivers and current app must be compatible.
Can I still download the APK from the Baidu Drive link in the video?
Do not rely on old mirrors. Check the publisher, version, and signature through the current official repository or a trusted store.
Must I remove the propellers when connecting a phone for tuning?
Yes. A configuration or USB fault can cause unexpected output. Keep the propellers removed, the aircraft disarmed, and people away.
Can the Android app replace a computer for every firmware task?
Do not assume so. Field use suits inspection and small changes. Perform firmware upgrades, target migrations, and major changes where stable power, backups, and recovery tools are available.
Why must Configurator and the flight-controller firmware be compatible?
A version mismatch can cause missing fields, changed CLI behavior, or incorrect writes. A similar interface does not establish compatibility.

Hello everyone. Today I would like to share a very useful field-tuning tool. You can see an Android phone on screen. Open the app menu and look at the first item, the one that looks like Betaflight. What is it? Let us open it. Ignore this for now. Is this not just Betaflight Configurator? How can it run on an Android phone?
This is a feature recently added by the Betaflight team. They used the Cordova framework to wrap the desktop Configurator in an Android app, so we can run the same Betaflight Configurator on an Android phone seamlessly. In the menu, you can also see a newly added option. There you can choose whether to use this portrait layout or—

One function concerns USB. Normally a phone works in USB device mode: connect it to a computer and you can access files on the phone, for example. OTG / USB Host lets the phone act as the host instead, so you can connect an external USB hard drive or flash drive directly to it. The same principle applies to a flight controller. This is useful, so how do we get it?
Open a browser and enter github.com. If you cannot access GitHub from China, I will share a Baidu Drive link in the description below. You can look there. First, I will show how to get the latest version from GitHub. If the version at my shared link has become old, you can send me a message or—
—leave a comment below, and I will update the link. On GitHub, search for Betaflight Configurator and open it. Below, there is a link to all releases. Releases are the versions: this is open-source software, right? Each new version adds another entry. Near the bottom is an Assets dropdown.
Then find the file for the appropriate platform: RPM is for Linux, EXE for Windows, and APK for Android. This is still a Preview and has not been officially released, but I have had no problems using it. You can download the APK. I will also copy it to Baidu Drive and put the link below the video. The APK downloaded from Baidu Drive is the same.
After downloading, open it and install it, just as you would install an application on a desktop. Once installed, you can use it as I demonstrated. If you enjoy this kind of knowledge-sharing video, leave a comment below. I will try to publish more videos like this. Thank you.
