Here we go... I recently crashed my Phantom 3 Professional due to an RC Signal issue... Here are the specs: I had taken off and was flying around a downtown area. I went to the other side of a tall building (which I had done previously without any issues) and suddenly got the RC Signal lost and Return Home Initiating in 7...6...ect... Screen. It also went to a black screen. Knowing there was a building between me and the drone, I hit cancel. I then noticed that the red x where the "return home" button was still showed which told me the return home had been initiated. I immediately tried it again and it would not cancel... I started walking to see if I could regain signal and noticed the GPS was not moving at all... Upon reviewing the flight log, when the RC loses signal it immediately and swiftly starts flying toward the "home point". I also noted that my sticks were not showing any movement. From my experience with losing signal, and the return home, the aircraft always pauses where it is, waits for the return home initiation, then pauses more, raises to the appropriate height, pauses, then returns home... From my flight log, the aircraft does not pause and seems to fly full speed in the direction of the home point... Thoughts?
