not only that, but you do have to have TIME, and alot of experience, bc im pretty good with computers, i'm good w\ autoCAD and mechanical desktop and i couldnt figure it out. And the planes you can download fly like sh*t, the only time I fly xtr is if i want to fly the foamy, that is the only plane that flies like it should. i hate to say all that but im just giving you my opinions.
