My p3 advanced gps is not working. I crashed it about 2 years ago. Broke the plate that the gimble and camera mount to and also a cushion pin. I just finally put the new parts on. I was very happy that all my 4 batteries and remote charged up nice. While in p mode the gps does not work. I says ready to fly (vision). While flying in p mode it doesn't hold position well even in pretty low winds. It also alerts atti mode frequently while flying. I put it in atti mode and of course way worse than. In f mode it's pretty much seems just like what p mode is doing. Drifting while hoovering. I realize I should check the gps connection, but a new GPS isn't real expensive and it's been crashed a couple times now. Seems if I'm gonna open it up anyway to check the connection I should probably just replace the old GPS anyways. I guess my question is could it be a problem elsewhere and not the gps module? The one thing I'm trying not to do is start throwing a whole bunch of parts at it and just guessing that it's the gps module. Suggestions please. And thanks.
