This will give you a more powerfull rotor and weak force effects. Resulting in a much easier flying. You can alter the settings as you please to get even more powerfull rotor, but with higher settings you actualy fly to fast and explode mid-air lol. The option for rotor is 'dmrl'.
Now you can fly you helicopter like a plane, without the annoying drag, with all the wonders of a heli, you can even turn instantly lol.
and ofcourse all in-game difficulty to OFF
