Hi, I am having a bit of an issue with my compass/gps. When i power up my Inspire 1 it goes through the normal warm up procedure. I then do a compass calibration, i check the IMU which is normally around 1450 to 1600. The GPS indicator is full and it says ready to fly. When i take off and get out of range of the sensors so about 3m high there is a message on my screen saying there is a compass issue and i am flying in Atti mode. I immediately land and recalibrate the IMU and the compass. It says ready to fly and i take off, it does the same thing. I tried about 4 or 5 times and in multiple different locations. Does anyone have any ideas? What could be the issue? How do i fix it?
