He-111 Coarse setter? & AutoPilot weaving.

[MadTommy]

Hello,

I'm learning to fly the He-111

One thing i'm a bit confused about is the 'coarse setter'. I don't really understand what it does. This is the 'ring' around the compass. if i alter it don't i screw up my compass directions?

Presently i think i have the auto pilot and directional gyro setup figured out but i don't understand the 'coarse setter'. By moving it i seem to be reconfiguring the compass. Is this right. Is it just mislabelled?

Also i often find the AutoPilot weaves a lot. I manually get myself on the desired coarse, set the AP to this coarse, engage it, and it weaves left & right of this coarse. Is it just a bit crap or am i doing something wrong. I do manually line myself on the desired coarse..

Thanks.
