I flew all 4 batteries today using the new 3.06 firmware. I had read about the new battery operation in the P2 assistant but really didn't pay enough attention to what it did. On my first battery I had been up for a while and was far away and high. I lost all control and was terrified. The P2 did a return to home just like it was supposed to do. While it was desending the rear lights were still blinking green . About 20 foot from the ground it slowed to a hover and then countinued down slowly. As it came down the rear light starting blinking red showing the battery was low. I got home and fired up the software and went to the battery screen. This time I paid attention to what it said. I found out I really didn't lose control but did a auto RTH like it was suppose to do. It is pretty cool that the software did what it was supposed to do. It knew by the distance and altitude that it was time to come home. Now I am trying to decide weather to leave it like this or unckeck it. I would like to hear the pros and cons of each way. What do you guys think and what are which way are you leaving it? Thanks in advance for your comments.
