Both should show up in AH as seperate controllers.
Gotta set em up in select joystick portion.
Select X45 and set all inputs to it and click apply.
Then select rudder and then select your peds and set your inputs for that.
That should be all you need to do and they should both work fine.
You can fine tune it in stick input or use a saitek control software if you wanna program it.
The CH Pro peds got toe brakes? can set that input as well.
