Hi,
I have a similar but wired Logitech joystick myself (Logitech Extreme 3D Pro) that connects to my PS3 without problem as a controller.
I can't seem to find a working configuration though to change the throttle in the IL-2 demo (tried all the buttons in vain...).
Does anyone know if there will be an option in the full game to make a custom button configuration so I can use my current joystick, or is my only option to buy a better supported one?
