Hi, I am very new to my P3 S, have only had it since the weekend and only been able to fly it a couple of times. I am struggling a bit with the GPS functions so had a little play this morning before work. I calibrated the compass, locked onto 7 satellites and tried to set the home point while it was on the ground in the centre of the lawn which didn't work, it gave an error, "home point failed", I think. I tried hovering and that seemed to work, allowing me to set the home point. I flew 150 ft or so and away about 300ft and then manually came closer to home (about 30ft) . At this point I pressed return to home and the P3 slowly landed exactly where it was. Any ideas where I could be going wrong?
