    Did it calibrate properly before you crashed? What happens now when you attempt to calibrate the compass? Please be as detailed as possible.

    Check the wire coming up from the compas if it has not been damaged during the crash.
    Did you calibrate at same place as usual? Nothing changed in the surrounding ?
    What is saying your sensors ?

    The compas is here not that good as it was at home. Usual value for mod is in the range of 1350 - 1450 depending where you are located, this in a open field area.

    It is on one of the horizontal bar of the landing gear, on the right if you look to the P3 from the battery.

    Also for the compas ?
    The Z of acceleration should be around of -1.00 and the mod around 1.00.

    Are you attempting the calibration outside, in the clear of any metal? This includes controller, cell phone, tablet, jewelry, etc.

    I had this happen. The compass wire broke off at the mother board. Crack it open and look.

    I had a similar problem so I ended up buying a new compass around $12 and it works fine now with no issues. My recommendation is buy a new compass it's a cheap try, you won't spend alot to see if that's the problem, which most likely it is.
