I don't know about the futaba, my brother has one, but I haven't played with it at all. However, from what I understand, the G2's controller that came with the sim also has a cable that came with it. I was told that my controller plugs into this cable, which plugs into the back of the G2's controller which plugs into the PC.
Another words you have to daisy-chain your controller to the G2 controller. I've just been using the G2 controller and have never tried it so take this comment with a grain of salt.
