Custom heli keybindings

Hello,
I can't manoeuver helicopters because I changed my infantry controls to something more suitable for me. It is however atrocious for heli flying. I'd love if you could add a keybinding section for helicopter because I'd like to have exactly theses controls : http://ift.tt/2ra6H7j

I don't use the mouse too so an option to disable mouse movement while flying would be great to avoid accidental movements. If you could do that that'd be awesome

Thanks in advance
