Noob here! Im curious how much time it will take to swap out a dead battery. Heres why...I plan to use my P3A to film my High School football games. But, I'm concerned about the process of swapping out batteries. What does that process look like? Do I simply land the P3, swap the battery and take off again (only taking a few seconds)? Or do I have to land, reboot, re-calibrate the compass, wait for GPS signals...etc, etc, etc? How long will it take? I dont want to miss any action on the field!?!? Any input would be awesome! So excited to get my new eye in the sky!!!
