While you say you have bad compass inside many things may cause this lots of interference inside, but if you also have same bad readings outside then yes maybe safer to calibrate just do suggested method according to your manual, once done correctly no need to keep repeating.
Regarding drifting , this can be particularly when flying at low altitude caused by VPs if lighting is not good or ground conditions are not good for position lock with VPs , to test drifting you need to be above 10 metres and out of range of VPs ,
Yea horizontal and vertical position hold seemed good, so imu should be ok.
It could have been vps since I was flying over snow, but there were bushes and grass and such sticking out of the snow.I'll have to go back and check the flight record, but I'm pretty sure I was over 10m for at least part of both flights.
And yes I was fully expecting compass interference at home, but not approximately the same amount out at the park with nothing obvious around to interfere. |
