Anyone having trouble with drifting in GPS, or toilet bowl effect? Well out of the box my was bad, and looking around the internet, it seems there is a simple fix.
What you need to know is your magnetic declination:

When you have found out how far east or west you need to go, then loosen your compass, and turn it around so it will match the magnetic declination angle.
I had to turn mine clockwise, so it is between 12 and 1 o clock position. If you see your Phantom doing a clockwise circle, then you got to move your compass clockwise, if anticlockwise, move anti clock wise. I adjusted mine several times and now is almost rock steady. Apart from a stop, will drift slightly counter clockwise for a couple of seconds then hover rock steady.
You can fine tune by moving your compass around on the leg. Think I got mine pretty good now.
