Hi. This is my first post and I am fairly new to flight sims but I have been putting some time into Flight since yesterday. The "W" and "S" keys on the keyboard control throttle by 1% increments. The wheel on the mouse moves them by 5% increments and the flight stick throttle ( I only have a cheap Logitech 3D Pro) works fine.Perhaps I am not understanding your problem? You might want to check your settings?
