Need a few terms explained

Ah right thanks.

So basically I just need to work out which in CoD is the one that gives me lower RPM and that's the setting for coarse. I think from playing it that would be the setting at the bottom of the slider icon on the HUD (the 3 bars you get in planes like the Spit).

BTW what's the half height slider on the HUD for the Stuka, the one on the right, it doesn't seem to be mixture or prop pitch as my controls don't affect it, unless I've mapped them wrong?
