Have been lurking here for a while, trying to learn a bit, and enjoying flying my Spark. I've been playing with Autopilot as an app, and really liked how it allows for some smooth shots. But I think maybe my novice skills finally won out. I was practicing with Autopilot's "cruise" mode, which manages the spark's yaw and gimbal tilt while you fly the other flight axes so it stays focused on a point while you fly around. May have had a wrong setting, but I lost visual sight of the drone as it passed around the corner of my house. When I turned the corner, I had could not see it, and then started getting GPS errors, Atti mode, etc. I attempted to RTH, no luck, intermittent visual signal, etc. Then I closed Autopilot, started DJI go, got an intermittent and choppy video feed. Attempted to recover and fly back, but finally fully lost signal. Here's the flight log. It seems to kick in after 9 minutes - I assume b/c that is when I switched to DJI Go from Autopilot DJI Flight Log Viewer - PhantomHelp.com The yaw errors I assume are something to do with Autopilot since it was controlling the yaw when I started the flight. Seems the last signal was at about 13% battery on the golf course. Anyone have any input of advice?
