Hi!

Is it possible to somehow do precise adjustments to the mixture/rpm levers? I need to fine tune my mixture/rpm and i find that its rather difficult since each "notch" of the mouse wheel increases the value too much. I want to "twist" the levers to make some fine adjustments but i cant find how.

If you are using the mouse, you can left-click, hold the mouse button, and drag the controls. This should give you a little finer control then the wheel increments.

Mapping to a controller button or using the keyboard keys is the best way to get a super precise increment.   (Or getting a dedicated throttle quadrant with physical mixture levers)

Dedicated throttle quadrant with levers is the way to go.  I currently use the Hotas Warthog and throttle setup but this is pricey.  Before that I used my trusty saitek yoke and throttle quadrant which did the job.

You can also assign mixture up and mixture down to keys.
