Hi there ,
I've attached the compass to the quad as the image below show (APM points forwards - between yellow arms). and the compass is Rotation_Roll_180.
When I'm calibrating the compass I keep getting reversed results (North shows South).
I've tried rotation none , yaw 180 , rotation_pitch_180 without luck.
1. Does this affect loiter mode ? Alt hold works fine , loiter and RTL don't work well , quad drift and fly somewhere it shouldnt.
2. What can I do in order to get good results from compass ?
Attached image how I mount my Ublox.

either u can manually repair it or try to search in ebay
The black cable was torn from the white connector , i don't see a way to "re insert" it , and the yellow was cut id the middle....
I had the same prob like you(EAST was WEST and vice versa) and loiter was highly unstable.....So while calibrating I use ROTATION_NONE . After doing this I found the compass gauge gives the proper direction. Now my RTH and loiter is ok
I've calibrated compass in my room , the directions looks ok.
Went out to porch , no GPS FIX and the directions are bad again.
I think ill go outside with the laptop and see how it behave there.
you must wait for some time to lock gps... if GPS is locked u can see blue light of APM become solid...
I think I can't arm the APM if I don't have GPS lock.
I'll go down soon and re-test it.
yes make pre arm check disabled or skip GPS
My pre arm is set to Enabled.
I'm going now down to open field with laptop and quad.
Hope all work fine :)
be back soon.

okk best of luck....., while enabling pre arm chk make sure all of your sensors are working and calibrated properly.... otherwise apm will oppose the copter to arm
Can I do the tests indoor or it must be outside ?
