Hello, I'm having the same issues with the control surfaces, but only when the engines are off or shutdown. Everything works fine when I load the aircraft with engines running. If you move the yoke to the left or right it flutters as if you were violently shaking it. The rudder is also inoperable.

I'm running FSX with other add-ons, but I have re-installed at least five times without installing anything else and still encounter the same issue. I also run everything as an administrator. I'm running on Windows 7 64-bit, could that be a potential problem?
