Ok so thought I would have a go at a range test with the p3. When watching the record back you can see that the P3 seems to be getting pushed from side to side even though I am heading straight ahead in GPS mode. The ground wind that day was only around 5mph so not sure if it was the wind pushing it around. One other thing I noticed on the video is the gimbal horizon was also moving left and right. Everything was calibrated and in good range. I came back most of the way in atti after I got signal back with the line looking better. Next time I will do the full run in atti .
