Game settings
In the game settings you can change controls: handle keyboard and change button sensitivity.
Invert vertical
Inverts up-down control keys while maneuvers.
Hide my flag
In the battle other players don't see your country as flag above your plane doesn't display.
Disable the voice acting
This function turns off voice acting in the battle.
Show the flag and avatar
Show the flag only
Show nothing
Pay attention that these settings affect only the display of other players' planes for you and not vice versa. I.e. after turning the function "show the flag only" on you will see only flag and nicknames above enemies.
You can also adjust controls depending on device you play on.
For touchscreen:
Sensitivity on vertical and horizontal axis and rotation sensitivity
The higher is sensitivity, the less effort you make to move your plane.
Dead zone:
You have gamepad, it has sticks. Dead zone is a move of the stick without reaction. I.e. when it's moved for a little bit - the game doesn't react. It lets you make the controls more smooth, if it's required.
For keyboard
You can settle individual buttons for controls. You can check standard controls in the "Controls" section.
