    I hope someone can help. I am not new to drones, but I just purchased a runner 250 pro. Out of the box it binded and flew great with GPS hold. I have a qr x350 pro and every now and then I do a compass calibration just to keep everything flying true. I tried doing a calibration on the runner pro and it will not complete the calibration process and now I have no gps hold and it does erratic things while flying. It will enter calibration mode, but the red lights on back will never advance past horizontal calibration. I have tried it in my back yard, out on the street, in my living room and it still will not work. anyone have any ideas???

    OK I tried it over and over even rotated it about 50 times only way I got it to advance to the next stage of calibration was to kind of shake it as I spun it still no GPS hold though. Five times it has even gone from flying Fast to only having about 1% stick control only up-and-down works getting frustrated. So I set it back down disarm it rearm it then I have control again but still no GPS hold.

    It will calibrate you need to be persistent and make sure you are in a magnetic anomaly free area.

    Slowly to make the calibration, don't too fast. As slow as you can.

    It may be because you are in Finland.

    Fly it in manual and do some very slow yaw rotations and the power down and up again. Do this 3 or 4 times.

    This should complete the calibration.

    Cheers

    Yazca, try to connect the battery into the 250 pro on ground floor.

    Don't do the connection while you are putting up the drone. Before you do the calibration, pls wait for the end of rear left led flashing.
    Moreover, after the calibration, please let it lay on floor for around 1 min. You may see the 5.8g video ( At the top of left corner)to show you that how many gps signal your drove are found. Give it more time.
