i setup here2 as the only compass to use on my tarot 680 HEX.
set the setting to relaxed, tolerance is 1800, using radio controlled on board calibration.
Here1 calibrates fine.
i have 2 here2s. none of them work with Orange. They both do work well on another smaller quad with cube black.
(i would kill for DJI style calibration in arducopter)
