    Your best hope is that the connector for the compass has come loose.

    Your compass may be disconnected.
    To check, go to the Sensor section of the app settings.
    Look to see what is displayed for compass data.
    If you see numbers, your compass is still good.
    If you have zero, your compass is disconnected.
    It could be the socket on the mainboard or one of the fine cables may be broken close to the compass sensor at the bottom of the landing gear.

    Start by looking at the fine wires going into the compass sensor.
    Take off the small cover plate on the bottom of the landing gear.
    That's easier than opening the shell.

    You should do a imu calibration after any crash or hard landings. Just my 2 cents
