I just had a new experience with my P3P. I haven't flown in over a week due to weather and commitments. I'm headed to Colorado next week and wanted to make sure everything is working. When I turned on the quad I noticed the battery was down about a light and a half. I know they start to discharge after about a week of no use. Since I was flying from my farm, and wasn't going to go too far from the take off point, I didn't worry about it. I got about a quarter of a mile out, over a soybean field and the friendly controller lady announced that the quad was landing. It still showed around 10 minutes of battery left. I touched the x in the red circle on the screen, with no results. By now it was at about 20 feet. As a last resort, I pushed the right stick forward and luckily it responded. I made it to a grass area along a trail I keep mowed in a natural area. I found it without too much trouble. It still had two solid lights on the battery. I took it back to the yard, and tried it again. I went to max altitude above the take off point and it flew until the battery was low enough to Go Home. I canceled that and landed it. So I tried the next battery. It was about one and a half lights down also. It did the same thing after a couple of minutes of hovering over the take off point. I let it land on the driveway, rebooted the battery, and again it flew until the battery was to the Go Home point. I assume this is the reason that it's recommended to always start out with a full battery. Glad I tried it at home and not in the middle of some Colorado Rocky Mountain High.
