Hi Svsmokey,
Well, I can bind my xbox controller thumb stick as axis command in DCS controls menu. But it only can be binded with some command that DCS allow analog axis input (Not Hat switch type).
Anyhow, I found the solution to bind the xbox thumb sticks as hat switch using by the app is called "Antimicro".
I mapped the analog thumb sticks as normal keyboard key and it works very well. If someone doesn't have HOTAS, it will be a cheap solution to play DCS.
