Hi all, I recently took delivery of my I1. I have replied to a couple of threads on here describing the problems I have experienced with Compass Error -switched to atti mode. This problem shows its ugly head every time I attempt to fly and then seems to disappear a few minutes later. So far I haven't had any crashes or accidents as I know to expect it now and until it clears I watch it like a hawk. However I noticed a new symptom when I tried flying yesterday and wondered if anybody else has encountered the same thing. After changing out the battery and powering back up I waited a few minutes until the safe to fly with GPS turned green. I took off and hovered for a few seconds, all was good and turned the bird around 180deg pointing back towards me, my screen flicked up a warning stating compass error again. Because of a reasonable wind I turned it around 180 again and brought it into land. At about 30cm off the ground the status turned green again and everything said it was good. I throttled up and climbed it went yellow this time staying yellow and reporting a continuous compass error. Brought it in to land and again at 30cm it went good again, I was able to repeat this about 4 or 5 times. Can't think of an explanation for this, no large metal structures or no cell phone towers etc. had done compass cal and checked the IMU status. Has anyone got any suggestions?
