Hello: So now I've had my first flyaway and I don't want to fly my P3S again until I figure out what I did wrong or ??? I just went out and did a flight tonight to play with my new ND filters. And it turns into a disaster -- almost. When callabraiting the compass before, I've had errors and moved, callibrated again, etc. I understand all that, or thought I did. This is from my backyard where I've probably flown 15 times at least. I had no warning at all. Everything looked cool Just safe to fly in GPS mode. Here is the healthy drones log, which doesn't even show any of these errors that I can see: https://healthydrones.com/main?f ... ;page_id=SENSORSGPS So about 22 seconds into the flight (very lower left) I notice the thing is drifting fast totally out of control (that's the bottom left flight area) back towards me and right then I get a COMPASS ERROR blah blah and it's totally flyling back the opposite way. I have no control. I switch it into ATTI mode but it won't respond, it's just keeps flying away back from me in the opposte direction. I have no control at all. I think I'm doomed. So it's out of control basically from the bottom left point to the top right point of the map trail that's when it was just having a mind of its own. (Screen shot attached.) Then I got control back. This went on so long, that it wasn't like I was dissoriented in ATTI mode and just flying away from me without knowing it. It would respond up and down, but not left or right it seemed. But then at that point I seem to gain control. And was able to fly it back and land. I then looked at the aircraft status and its a HUGE COMPASS ERROR warning inside the app, but it has never done this to me after the aircraft has taken off. It's warned me on a few occasions as I was callibrating or setting up and I've moved, etc. So what did I do wrong? Or what happend to the aircraft? I had hoped the healthy drones data would have shown me what was going on more, but everythign seems to be OK. Any insight from more experienced users would be greatly appreciated. I just want to understand what I did (or didn't do.) Quint EDIT: Here are the Phantom logs: Phantom Log Viewer - PhantomHelp.com You see where I finally am able to switch into ATTI mode, while there are all these YAW errors. But then it switched back to GPS on it's own at some point or ???
