So I've been flying flawlessly for months now. Last night I had a small compass error for the first time. Luckily it only lasted about a second then found its bearings again. What I have noticed that is different is that where I used to have a 'D' next to my distance reading I now have a flashing location symbol with an 'H' instead. Have not changed any settings and I don't know if it could be related to the compass error. It was pretty windy up there last night.
