Do you have the drivers for your stick? Go to the net and get them.
(sounds like you don't have them, you are running in default settings mode, so the drivers for throttle and Rudder are absent)
One way is to check in the windows device manager for you Sound Video and Game Controller Driver versions
Note that some games require sticks to be set up in Windows first then they can detect them.
I have the latest Logitech F710 controller and it was very hard to get going correctly having to be working in Windows first.
Go to "Start" then "Run" it will show "Open" and a little window then type in compmgmt.msc hit "Yes" and select device manager
