I am loving this and woff - I bought them both just recently - fantastic immersion!!!
Anyway in woff my thrustmaster warthog and vbksim rudder pedals were easy to assign.
But in wotr it would recognize my pedals as rxaxis and then I woul choose bind and save the profile and exit. Flying or coming back in to assign keys it would be gone.
I checked key files for both games and the only difference I could see was a space after the name of the rudder pedals in wotr.
I copied and pasted the rudder section from woff to wotr key files and now it all works.
Just in case the fix helps someone and reporting a bug.
