ok, i found this on another forum :
In the main IL-2 folder there is a file named
rcu. Edit the rcu file in Notepad add the line
then create a new text file (Notepad) and paste this lines
Code:
mp_dotrange FRIENDLY DOT 18.000 COLOR 2.500 RANGE 0.005 TYPE 3.500 ID 0.005 NAME 0.005
mp_dotrange FOE DOT 18.000 COLOR 2.500 RANGE 0.005 TYPE 3.500 ID 0.005 NAME 0.005
timeout 60000 file settings.rcu
The values in those lines will give you dots at 18km, aircraft type at 3.5km, color (friend or foe) at 2.5KM, everything else at 5m (= disabled)
Save the file as settings.rcu (be sure notepad didn't renamed it as
settings.rcu.txt, if rename it as
settings.rcu)
Edit settings.rcu according to your preferences. Values are in km, I guess you figured out how to set them by now.

ah.. forgot to tell you that you need to show the command console (shift+tab) or values will not be changed, then wait a little bit and close it again (shift+tab). If somebody have a better solution i'll also use it
