mouse: check out your local hobby shop. There are lots around but you will need a pretty big area to fly one indoors with the length of the rotor blades etc.
It is great that they finally came up with true jet engines for modern r/c planes. When I was growing up if you wanted to build and fly a jet aircraft you had to go with a ducted fan which was basically a standard piston engine in a tube. Made the brrrr noise like a piston engine too. Those planes even sound like jets when they fly by etc. That airbus even had the high pitched whine like the real thing....
