Hello to all! First post ever here... I have been using a P2V+ since one year back. There have been some threads about briefly getting solid red lights during flight. In my case I'm not able to tell why this happens, because I see absolutely no indication of any error or need for calibration, neither in the DJI Vision app nor in the DJI Phantom 2 Assistant. The lights go solid red for a few seconds and then return to normal. Nothing strange happens: the thing still flies perfectly, no message or error in the Vision app, battery charge still well above warning limit. I did notice, the few times this happened, that one common denominator was that I was descending when the red lights appeared. Is it an undocumented warning about too high speed of descent...!? My flight mode is almost always Home Lock. Oh yes, another common denominator (kind of...) is that there were power lines in the neighbourhood, but in each case I was separated from them by 200 m or more, so this doesn't seem a likely explanation to me. What's the verdict - is this something I can just disregard, since there have been no visible effects whatsoever?
