Today I was flying my M200 V1 for a couple of missions that I normally use the P4P on (thought it was about to rain). On the first mission I flew off track multiple times but only when flying south. I stopped it and had to refly with my P4P.
So I did another test at another site and the same thing happened only this time it only veared off when flying Northwest. I thought I grabbed a screen shot on the first mission but did not. I have a screenshot on the second mission. I did a compass calibration after the first occurance. There were NO error messages or warnings. Apparently the M200 series had compass problems several years back but that involved warning messages.
When I initiated Go HOME it came straight home and did not waiver at all. I have no idea if this is a compass issue, firmware issue, or some other issue. The M200 the latest firmware as do the batteries.
Any help will be appreciated.
