Orignal XBox R/C system

I have this idea that I woud like to implement although I am not an expert on Electronics.

I have the shell of a broken XBox what I want to make into a Transmitter for 4 seperate Remote Control Somethings (I havent decided this part yet). I want the controllers to be the controls for the 4 said remote things.

Here are my problems...

1. The xbox controller is basically USB and I dont know how to decode the signals it outputs. Although I did find this site "http://euc.jp/periphs/xbox-controller.en.html" that could help.

2.I dont have nor know how to make a transmitter or receiver.

What I am looking for... Any help someone is willing to give.

Thanks,

NobleDell
