Thank you for viewing. This is a set of a flight yoke for flight simulator and the application (Xplane10). The flight yoke includes the main unit only, and the application includes the main DVD (8 discs), instruction manual, and box. The flight yoke is CH Products FLIGHT SIM YOKE. The application is XPlane10 (Japanese version). The flight yoke connects via USB. After installing the application, you can enjoy the flight simulator almost by default by connecting the flight yoke. I was able to enjoy it to a certain extent even with a home computer (i5 5th generation + GTX750). It becomes even more realistic if you set the switches on the flight yoke in detail. Please purchase after understanding the product contents and condition if you have relevant knowledge. Thank you.
