Reversed compass when the controller rotated by 180 deg

Hi,

I’m flying an F765-Wing controller running the ArduPlane. The mavlink telemetry is transmitted by a Crossfire link to a mobile phone running QGC. The controller is rotated by the 180 degrees yaw, and the appropriate parameters are set so that in the Mission Planner the geographical directions are shown correctly. However, on QGC (both daily build and the version from Google Play) these directions are reversed, so N is where S should be etc. Is this a problem of QGC or ArduPlane?

Create a GitHub issue. Save a telemetry log which shows the issue. Link to the log in the issue and then I can replay it and see what is going on.
