I think i feel you.
I traded my cougar for a warthog last year and found myself struggling with BMS configuration more than any other sim i use (probably due to how seamlessly integrated the cougar was to falcon4).
what i came to realize was that at the same time that we all moved from the cougar, there was also a shift in the tendency to highly-script everything into our Foxy profiles like we used to.
i remember, you could find tons of profiles, and many of which allowed you to be up and flying immediately with just some axis assignments.
the new method was , for sake of speed (which i dont entirely agree with since we all are now running USB3 in very fast CPU/Northbridge platforms that were not around, nor performant enough, years ago.) is to go with just DX strokes, instead of all the keyboard-mapping we were doing in Foxy.
So now, most everyone is actually not running much beyond the included profile in your C:\Falcon BMS 4.33 U1\Docs\Key Files & Input folder and just DX profiling. we also no longer need to save axismapping.dat - maybe thats why.
i personally miss all the automation i had in my cougar profiles customized, holding a button down for 2 seconds to get a third function, or even a macro of strokes, was pretty fun and it really made you get to know the keyboard strokes.
