You cannot set the controls exactly as you wish in options.
What ever you set them to, you still have to press another key to have "precision" control, otherwise pressing what ever key you set just gives you maximum throttle/rudder. You can also not set a button to center rudder or cut throttle (like you could in 2006).
Having non "precision" control (ie, having to keep the key pressed and then only being able to have maximum rudder or throttle) is pointless when using the keyboard or joystick.
Even just using the mouse doesn't work 100% as it only seems to steer the left rudder?
also, could you bring back the pan option on the joypad or make it programable so that you don't have to keep grabbing the mouse to pan around.
Rant over,
Nevertheless a great simulator which just needs a bit of fine tunning
