External compass issue.

Hi all.

I have a fly away problem in loiter, AC 3.0.1, and I've seen that there is a misleading issue with my external compass HMC5883 (3dr robotics). The arrow silkscreened shows an incorrect direction.

I don't know if that corrects my fly away problem, but the true is that I have compass_orient parameter = 0 (not correct).

I will test tomorrow.

Please, advise at wiki.

This is APM 2.5 (see compass IC code and arrow)

This is the external mag (y arrow and IC text):
