I have several UAV's, Spark, Mavic Pro, P3P, P4 and a P2 (Gopro Version). The P2 keeps me humble as it has the well document weakness with GPS, FPV range and a few others with the gimbal steadiness. Its been over a month or more since I last took it out, and I just got in a new set of props (trying to reduce the jello effect). I put on the props, check the battery (4 bars). Fired up the RC and FPV screen and off it went. With the new props it sounded a little quiet than normal, but I take that as a good thing. I fly over an industrial area near my home that I am very familier with as I have done and do many inspection of commercial and construction projects. On the return route home all was well, as I pushed it to the limits. 600 meters out I got a problem, battery went from 25% to 10% within seconds. Here's the video
