Just received delivery on my P4P yesterday. After fully charging the batteries, it connected with the RC and flew very well. On the second battery charge, firmware was updated. I flew it a second time and the camera worked at the beginning of the flight, but suddenly pointed straight down during mid flight. Now my gimbal flops around during initial boot up, and I can't complete the boot up procedure.   I also got a message of gimbal overload. Asking for help. Thanks in advance.

That sucks..
