I purchased a Tile a device that connects with bluetooth to your phone so you can find lost things. I thought it would be a good idea to attach one to my X-Star Premium. Went to fly today and could not get the compass to calibrate after 3 tries finally got it. Took off and was about 100 yards out and had a magnetic interference it went into atti mode I landed it and and removed the Tile tracker. Flew fine after I removed it. Has anyone else attached a tracking device to there drone and if so where to mount it.
