Quick fixes

Radio not detected

  • Use a desktop browser. Chrome or Edge are the safest choices for controller/radio input.
  • Put the radio in USB joystick, HID joystick, or simulator mode before calibration.
  • Use a data-capable USB cable, then move a stick or switch once after plugging in.
  • Reload acroFPV after reconnecting the radio.
  • Open the radio troubleshooting guide.

Controls feel wrong

  • Run the controller wizard again from the Controller panel.
  • Center sticks before each capture step, especially throttle.
  • Move only the requested axis during calibration.
  • If roll, pitch, yaw, or throttle are swapped, restart the wizard and remap each channel.

Low FPS or stutters

  • Close heavy tabs, screen recording tools, and other 3D apps.
  • Try a smaller indoor map first, then move up to larger cruise maps.
  • Keep the browser window visible and avoid battery-saver mode while flying.
  • Update your browser and GPU drivers when possible.

Clips or Parts missing

  • Saved clips and Parts live in local browser storage.
  • Private windows, cleared site data, or a different browser profile can hide previous clips.
  • Exports create files through your browser download/share flow.
  • If download/share is blocked, check browser permissions and try again in Chrome or Edge.

First-flight checklist

  1. Open acrofpv.com in desktop Chrome or Edge.
  2. Connect your radio in USB joystick, HID joystick, or simulator mode.
  3. Move a stick or switch once so the browser can see it.
  4. Run the controller wizard and map throttle, roll, pitch, and yaw.
  5. Pick a map from the Map panel.
  6. Fly a short line, set Clip Start and Clip End, then Save Clip.

Controller setup details

Recommended setup

Use a real radio/controller over USB on a desktop or laptop. If your radio has multiple USB modes, choose the joystick, HID joystick, gamepad, or simulator option.

If the OS cannot see it

Try another USB port, another cable, and a full browser restart. Charge-only USB cables are a common cause of controller detection issues.

If the browser cannot see it

Open acroFPV after the radio is connected, move a stick once, and check whether any browser permission prompt is waiting for input.

If calibration is noisy

Keep sticks still during center steps, avoid resting pressure on the gimbals, and redo the wizard after changing radio output modes.

Clips and Parts

Saving a clip

Fly a line, use Clip Start and Clip End to mark the best section, then Save Clip. Short clips usually make stronger social edits than long raw flights.

Building a Part

Create a new Part in the Clip panel, add your strongest clips, then export or share it as a bundled Part file.
