When I plug my phantom 2 into the computer and run the assistant software, an error message pops up saying "abnormal compass data". In addition, when I turn my phantom and controller on to fly it, the LED lights turn solid red. In the assistant software under the tools tab, there is no compass data whatsoever. I had bought a new compass and was wondering if maybe that was the problem. I also attached the larger legs for the phantom, so the compass has moved from it's original position on the smaller legs. I'm not sure what the problem is and I would appreciate anyone's help. I have attached the photo of my assistant software issue regarding the compass data.
