I've just connected my P1 to the computer for the first time, I turned on orientation and home lock and the fail safe switch.. Other than that I don't think I did anything else.. I've just took it for a test flight (it is a bit windy) but it struggled to get GPS lock, when it did and had home position set I took off and it started asking red, and flight was very rough and uncontrollable.. Interestingly when it was on the ground it did the rapid green home position light thing.. So I thought the battery was flat so I swapped it.. It did the same.. I kept it in the air this time but it was bouncing all over the place.. Turned it to ATT and it was stable so it's not the wind. I'm flying in my garden where I always fly, and always get good GPS.. I'm a bit worried about flying it now..
