My compass will not recalibrate, very frustrating. The I1 flew great last weekend with no problems. Tried to fly it the following Thursday in a different location and got a compass error. Was out in the middle of a field with nothing around me but sky and earth. Tried multiple locations in the field with no success. Brought it home and got the same compass error even though I have calibrated it at home in the past. Have the latest firmware on the I1, controller and iPad. Tried different batteries and still got the error. Have tried calibrating it doing the dance and just rotating the I1. Both failed to calibrate the compass. Anyone have any ideas?
