Just playing around today, and for the most part the day was too windy. So at the end of the day, it died down a bit so I went for a quick flight. After taking off, I noticed that occasionally one of the white lights under the left front motor would flash occasionally. No other warnings, but just that one light. I would left-stick turn the bird and it would come on solid, only to start flashing (about a one second interval) in about 10 seconds. As I went higher, I seemed to lose a bit of control. It also seemed like the bird lost track of how high it was, since it kept going higher and higher. From the video I shot, it was panning left/right like it was struggling to maintain position, and drifted off to the north at a fairly fast rate. Then, after getting a low battery warning, it took FOREVER to bring it back to me (I flipped it into RTH mode). First, does the blinking white light under the left front motor mean anything, or do I simply have a loose connection somewhere? Also, since it was windy earlier, I'm sure I hit a good amount of wind when I went higher and higher. Would this cause the left/right pan? Finally, is it possible that high winds would confuse the altimeter? (Not sure how altitude is monitored, is it simply GPS, pressure sensing, or what). Scary to almost lose control and almost run out of battery!
