The USB interface is an RC buddy box to PC USB interface, it will work with up to 8 channels, channels 1 to 4 will be used as analogue inputs for the joystick giving 4 axis. Channels 5 to 8 will be used to activate the button inputs. If your RC transmitter has less than 8 channels then the interface will only generate output for the same number of input channels i.e. if you have a 6 channels set it will produce 4 analogues and 2 switched channels or if you only have a 3 channel transmitter then it will just produce 3 analogue channels and no more.

The USB interface will work with any PC program that uses input from a PC games port joystick be it a RC simulator, Flight/Combat simulator or any other game. It will not work with any program that requires it's own special RC transmitter interface. It will work with most makes of RC transmitter that output a standard PPM buddy box signal from their training socket.
