Is it possible to Buy the G3 package WITHOUT the remote
By "remote" are you referring to the controller?
The controller actually is the identifying hardware that tells the pc what's connected as well as being a simulated model airplane radio transmitter. It is both the USB connector and your TX. It also works as a dongle. Yeah, what a name, "dongle". But that's the term used in the pc world to identify a thing that you have to have in order for a software package to work. A dongle is piracy protection. You can copy the CD and make a billion copies, but without the dongle, all you got is CD copies. You have to buy the dongle to get the simulator. That defeats the software pirates. And you need a TX to fly the simulator, so one comes in the box.
The application has the added benefit that someone who is interested in trying out RC can do so without having to invest in radio equipment, airplane, and support equipment. Of course, if you've already got the radio stuff, you can also plug your TX into the G3 controller, which will then interface to the pc.
The answer is no.
