I've had almost 30 flights with my P3A so far. Earlier today, after calibrating the compass before each flight, I took off from the mountain cliff right at sunrise to get some low cloud footage with the sun shining on it and flew for about 15 minutes and as soon as I landed, you guessed it, I realized I forgot to hit "record", so I immediately put a fresh battery in and flew again. About midway through the 2nd flight, that's when the compass problem began. The bird tilted left and I got a compass error, so I switched to A-mode briefly, then back to P. Bird steadied for a while then errored again a few minutes later, tilting the horizon to the left again. Repeated steps and it went back to normal. Took the bird up for a 3rd flight about an hour later and had no problems. So, questions are... 1) Is this typically what happens with those of you that have had compass errors? 2) Did you get your compass error after inserting a new battery and immediately flying again? 3) Perhaps the error occurred due to the bird still being warm after the previous flight? It seems like an isolated incident, and healthydrones.com didn't show the compass errors to be in dangerous range. If you want to see the area I was flying, see here PS, I think the part where the quad tilted were edited out, but I thought showing the site I took off from might help.
