Yesterday I had a problem with my Phantom 4. I flew the Ph 4 to 400m distance then pressed RTH button on the controller. The Phantom returned to the takeoff GPS coordinate without any issue. However, during landing it started to fly in random directions with high speed. I quickly cancelled the RTH and barely landed it manually. Could someone explain me what happened so I could avoid such situations in the future.
The flight record is available in the following link:
