A magnetometer is for a compass. Nothing to do with autolevel.
Okay, I thought that a 3 axis magnetometer was needed so the fc would always know its position, not just north/south but pitched up/down and rolled left/right? Like, if I calibrate it while on a level surface, then unplug the battery, roll it 30 degrees over and plug it back in... it knows it has been rolled 30 degrees? I get that it would know this if the power was on and it sensed it was being rotated... I just don't know how it would know if power was disconnected?
Or do you have to calibrate on a level surface every time a new battery goes in?
