Here are the video links to my problem and actual footage of the crash. https://vimeo.com/92949561 https://vimeo.com/92949562 Mind you that i did all my pre-flight inspections and check ups, i even do a pre-hover test to make sure everything is still good and yes I do all my basic and advanced calibrations and manual compass calibrations. I press my record button on the go pro after all gps are locked in and then proceed to pre-hover, so No i did not just take off right away. No cell towers in the area, no where near airports or commercial buildings that could interfere with signals, and yes the gopro wifi is turned OFF. All batteries are good on both tx and phantom unit, and i also do physical inspections inside the unit itself for loose connections or any loose debris; So i do take care of the unit and I do not mis-treat or fly crazy or erratic. I fly with the intention of getting the most steady shots, so small and slow movements and no fast throttle. You can see my previous footage on youtube which I recently posted a few weeks back. This was on GPS Mode and was never on ATTI middle or Bottom. I did not panic as well, you can clearly see the footage that it just banked FULL throttle on its own without stopping.
