I did look at Chucks guide, in fact, have some of it printed right here. I am not sure what default profiles you are referring to, but not a single button was mapped except yaw pitch roll and a view. Nothing for the rudder pedals. Sure, everyone will customize the buttons, and Chuck's guide did a good job of highlighting which ones to focus on.
@shu77 I definitely agree that MSFS will bring more people to DCS. I don't think there is any question. There is room for both and they have an entirely different focus.
