Take a look into Falcon BMS 4.32/User/Joystick/Generic/Kolbe/CH Fighterstick & Pro Throttle
There’s a document on how to program the stick and throttle.
Also in Falcon BMS 4.32/User/Joystick/Generic/Kolbe there’s an Excel document called BMS-DX-Generator1_6.xls
If it works for CH Stick and Throttle like it does for the X52, using this spreadsheet is pretty easy.
If you don’t know all those functions yet you can just use the assignments already made within the spreadsheet. All you have to do in this case would be to enter the device numbers, select your input device in the output column and then copy and paste the assignments into the keyfile you choose to use. Once you got the hang of it, it’s s so easy you feel like cheating:)
