radio controll

100 bucks for a 99 percent ready to fly plane, it was the firebird phantom, a very simple mid size plane, i'd say no bigger then the are of a small coffee table, if you get my jist...

and it included the remote. now as far as i see, the antenna is connected to a little black thingy. Since the antenna is connected to that, does that make it the transmitter?

if so, it only seems to have 1 pin connected to it, other then the antenna....
