Hi all, did some flying today, took off with home position locked, altitude and distance both 0.0, but later on as I was flying I noticed that my distance was 142 meter and my altitude 246 meter. I was a bit puzzled; how can this be...? I did not switch S2 to reset home position. Also, here in holland we live pretty much at sea level, should that be of influence, although I do think the altitude is measured from take off point. Had 9-10 satellites the whole flight. Did switch between GPS & ATTI mode a few times. Easy explanation..?
