Gentleman, I have a compass calibration question. I am trying to use the I1 to inspect the inside of an all metal building with lots of large magnetic fields. I have several successful flights outside but when I move in the building I get the “Compass needs calibrated” warning and it will not let me arm the speed controllers and fly. I have armed the speed controllers outside flew into the building and then the “Compass needs calibrated” warning appears during flight, I did not land but continued to fly reaching altitudes of about 5 stories inside the building and had no problems. Then landed and could not take off again. Long story short I need to be able to fly without compass calibration, I know it is capable because of the test so I need to find a way to bypass this step and do all the flying manually. Can anyone help?
