RE: RF Without The USB
cfossa, I think he is just looking for a way to bypass a controller all together because he says that he doesn't want to have to pay for a controller; he wants to just use his tx.
But even with the serial port controller, don't you need a Realflight controller? I think, Mudsurfer, that with RF you're going to have to buy an Interlink/serial port controller just to play the game. -Andrew
