I’m glad to be helpful. It really is a bit more complicated than I expected, and I lost about an hour before figuring out how to set it.
Since I’m writing this post, I’d like to explain a couple of things.
First of all, what “l3crusader” said about reassigning the axes every time is partially true. If you set everything as keyboard as I said, then close Falcon and launch it again, you’ll see in the controller menu that falcon automatically selects X-55 stick.
Now, if you leave it like that, you won’t have problems, you can check everything from that screen. Your stick, X and Y axes, the Z axis on the stick (rudder) and you can see the throttle and set AB.
BUT if at this point you change the controller to anything other (throttle or keyboard), then it will indeed reset everything, so you have to set it again as keyboard and assign the axes again.
As long as you don’t touch the controller selection in the menu, and you leave it as X-55 stick, like in the following picture, everything will be OK. You can check everything and you can assign button of your hotas directly from Falcon’s menu.
I recommend creating another key file, as you can see I created “X55.key”. Just save your settings with the name you want.
