Happy to report that my phantom survived my 3 month vacation in the Philippines except for the broken stock gimble guard. The bird functioned flawlessly. My ipad pro overheated once and it was because I had Spotify running from the background. My phantom and ipad were kept with current updates while on vacation. No major callibration were performed except for the obstacle sensors when required after installing firmware upgrade. Maximum distance I attempted was 3500 meters. Hand caught my drone in almost all my landings. Hand launched over water on more than one occassion where vertical clearance was not adequate. I lost connection more than once from a launching position where there was a compass error. I just re saved home position once I was clear from the interferences. I had a good vantage point and moving from another place void of compass interference was not an option for me. I tried night flying also again from the same place where there was a compass error. This was scary because I was flying in Atti mode until I cleared compass error and got a GPS lock. I am a very satisfied phantom 4 pro obsidian owner. Only one complain though, it takes me 5 minutes to properly setup the phantom for flight.
