With the CH pedals, I use the toe brakes for yaw but I had to script that in the Control Manager. Sliding to yaw takes a long time in a space combat game, and if you meet a twist rudder user, you're going to come off worst.
I have the TM set up with Saitek rudder pedals and have similar issues. The TM controls are easy enough to edit in the Options menu, but the sensitivity and range on the rudder pedals is horrible. Nothing happens until you get to the extreme end of the range and then it's either full on or nothing causing overcorrection. I've tried both ways and settled on using the brake action to initiate yaw. I was thinking of changing to CH pedals to see if that would help, but I guess from your post that it's not the answer...
Turns out I was using the Toe breaks instead of the rudder, and yes its set to axis now - which makes it a lot less sensitive and good. . My only issue now with it is the fact that it keeps sliding on the carpet a bit.
Any other must have settings I should have on warthog, im not sure what button to use for Oculus rift head position reset or in game overlay menu for steamvr.
I wish in game had a visual of the controller used and pedals so that I can see what each button is already mapped to visually. would be nice!
I reconfigured my pedals to use the axis setting and it is improved. A strategic piece of wood stopped the pedals from moving, but now it seems I need a chair w/o wheels - LOL. there is a diagram of the default Warthog layout in the ED pilot guide manual. http://www.scribd.com/doc/236560722/Elite-Dangerous-pilots-guide-manual-tutorial
