Hello, We have been trying some indoor flying. We filmed inside of a warehouse recently with some good results. I was asked to fly for visual inspection reasons inside of a 70ft tall steel boiler and it was a NO-GO. We flew in "Attitude Mode" and still no luck. The compass/GPS didn't like it unfortunately as it could not calibrate. Electro/magnetic interference. Anyone aware of a work around? A patch or way to disable the fail safe mode enabling a pilot to fly fully manual/visual? We are flying both the Phantom 3 Pro and Inspire I. Thanks a lot!
