Xbox 360 inverted controls ?

I have searched the form about everything about key mapping the xbox controller but nothing about Inverting the sticks, I want the right stick to reserve the camera down to look up , up to look down
thanks for any help

 

You would have to map your own controls. Playing#Controls Scroll down to "Configure your own controller." Gives semi-detailed instructions, my controller recently broke so I can't create a video tutorial.

 

Thank for the reply , all I want is for the the camera pan stick , the right stick up and down camera to be reversed, (down to be up , and up to be down) like an airplane you pull back on the stick you go up forward u go down
