New out of the box X star premium and first time owner here so I'm having some trouble getting off the ground. Can't even start the motors until the compass calibration completes and it fails every time. I've turned in circles til 'I'm dizzy. Magnetic interference is on the controller readout but I thought I was far enough away from any metal. Maybe clothing, zippers, snaps? Or would the 0 degree F temperatures be a problem?
