This is an update to the MoD here https://www.digitalcombatsimulator.com/en/files/3300580/
which I was having difficulty getting the tweaks to work with the current DCS build and so i updated it with the following changes.
The new settings are separate and listed as "Fine Control" for the following:
- elevator trim speed from 1.0 to 0.2
- rudder trim from 1.0 to 0.1
- gun range and target size from 1.0 to 0.1
- gunsight dim from 1.0 to 0.1
