That is unfortunate that you feel that way.
However the next time you intend to part with so much of your hard earned cash, I suggest you do a little more research to find out what you're actually getting yourself into.
Having said that, have you tried the tutorials? Or have you tried loading the panel state to "Ready for takeoff"?
The thing is now you can't really get your money back, why not try learning it and get your money's worth out of it, beacuse the T7 ain't gonna be much easier to learn either.
I also suggest a likkle patience...as it took me a month almost before I goth the thing off the ground.
Hope it works out well for you
