FutureAir

I have a flight simulator donated to my company with no instructions on how to install or just how to get the sim working smooth. Right now the simulator is work but only working enough to fly a bit its still pretty laggy. All of the plugs are being used except for avionics input on the sim. If anyone has any idea how i can get this sim working that would be great like even pictures of how your sim is set up would help. Also the nav isnt working the display lights up but it does work.
