Huge yaw movement everytime I take off

Hi Guys,

I have seen this problem as well using ver 1.5.5

here is a video.

I think it is related to Compas calibration.

We discovered that we have to wait at least 2 mins at the exact location where it will be calibrated before calibrating it. All this to make sure MAG gets stabilized before calibrating it.
