Why does my FPV radio not show up in the browser?

Use a data-capable USB cable, choose USB joystick or HID joystick mode on the radio, move a stick after connecting, and reload the browser page if needed.

Which browser should I use for FPV controller input?

Desktop Chrome or Edge are the safest choices for browser-based controller and radio input. Android Chrome can work when the radio exposes four usable gamepad axes.

Why is yaw missing on Android Chrome?

Android Chrome may not expose the classic joystick axis used for yaw. On EdgeTX, use Advanced USB Joystick, Gamepad interface mode, and map yaw to rotZ or RZ.

Radio setup

FPV radio controller setup for browser practice.

A real radio makes simulator practice feel useful. The browser just needs to see throttle, roll, pitch, and yaw as stable joystick or gamepad axes, whether that comes from EdgeTX USB joystick mode or a configured ELRS simulator dongle.

Setup checklist

Use desktop Chrome or Edge, or Android Chrome after confirming all four axes in Gamepad Tester.
Connect your radio with a data-capable USB cable.
Choose USB joystick, HID joystick, gamepad, or simulator mode on the radio.
Open acroFPV and move a stick or switch once.
Run the controller wizard.
Map throttle, roll, pitch, and yaw slowly and deliberately.

Classic vs advanced joystick mode

EdgeTX radios can expose joystick-style output over USB. Classic mode sends configured output channels in order, while advanced joystick setups can expose different interface modes and channel behavior. For acroFPV, the practical goal is simple: the browser needs stable axes for throttle, roll, pitch, and yaw.

Radio-specific setup notes

RadioMaster Pocket ELRS

Use a USB-C data cable, choose USB joystick or simulator mode when prompted, then run the acroFPV wizard. Its compact gimbals are usable, but small stick movement can feel sharp until rates are softened.

RadioMaster Boxer ELRS

Use wired USB for first calibration even if you plan to fly wirelessly later. Full-size sticks make center capture easier and usually transfer better to a 5 inch freestyle quad.

ELRS simulator dongle

Bind the dongle to the same radio model or bind phrase, confirm channel order in an OS/gamepad tester, then calibrate in acroFPV. If anything is weird, fall back to wired USB until the radio mapping is clean.

DJI FPV controller

Use it only if your computer or browser exposes it as a usable gamepad/HID controller. For general FPV, EdgeTX plus ELRS is the easier long-term simulator and real-quad path.

Android Chrome and missing yaw

If desktop Chrome works but Android Chrome only shows axes 0, 1, and 2, switch the active EdgeTX model to Advanced USB Joystick. Use Interface mode Gamepad, set circular cutout to None while testing, and map yaw/rudder to rotZ or RZ. Then unplug and reconnect USB before testing again.

Common mapping mistakes

Throttle reversed

If low throttle reads high, redo the wizard and watch the requested direction carefully.

Roll and yaw swapped

Move only the requested stick axis during capture. Extra movement can make the wrong channel look strongest.

No input detected

Try another cable, another USB port, and reload the page after connecting the radio.

Jitter near center

Keep the sticks still during center capture. If needed, recalibrate after the radio has been connected for a few seconds.

Practice after setup

After calibration, do not immediately chase tricks. Fly a slow line and make sure throttle, roll, pitch, and yaw all feel predictable. Good setup is boring because nothing surprising happens.
