Hello, I have been flying arducopter for 3 months now and I have been a little surprised that the copter is very stable with the quite old 3.2.1 firmware, but one thing that has been very annoying is that I need to recalibrate the compass almost every week I fly. Is it normal?
But another issue that has been disturbing me lately is that this Sunday I wanted to fly in a different location, I flew there before, and calibrated the compass there before too but this time when I calibrated the compass the offsets were much different from normal (my normal offsets are around [-210, 15, 50]), but this time they were very close to 0 on all axis, maximum 10! Is that normal? The copter flew fine like always but after looking at the logs I noticed many compass / magnetic field interference issues, I also needed to calibrate it twice before it succeeding!
Also note that this happened the same day the world changed time, idk if that matters just pointing out.
I will fly tomorrow and calibrate it again in another location close to where I live and see the offsets!
