Nothing wrong with turning sounds down. i have my engine and tread sounds down some so i can hear and talk
on vox. Default was so loud that it made my vox useless. I do leave my engine up some so i now it's running and
when to shift gears up or down.
Don't make the mistake and think this makes u silent - the enemy gv's can still hear u.
Porking enemy ords always helps (LOL what's up AAolds -- me porking ords -- well i never -- maybe i did heheheheh

)
I personally find this no different than all the hoing,running,stay high,play it safe, and all other bs going on in planes.
