Hi Rich, welcome to the incredible world of rc-flying! I believe you made a pretty good choice for your first heli. Art-tech does make a usb cable for the 6-channel Transmitter, the part no. is 302101. Maybe Hobby Lobby carries them? On the other hand, what you need to do on the simulator is get used to different orientations of the heli and what to do to be able to hover it, which you should be able to learn on your current simulator with the 4-channel transmitter.

I would also suggest a visit to www.falcon-3d.co.za this is our local falcon website. You will find an article on it called "hovering for dummies" which is intended to help beginners get their falcons in the air with the mimimum of hassle.

Best regards
