I just ordered a Walkera #36 too with brushless, lypoli and carbon blades. I can't wait fo it to arrive. Can I ask you what store did you order yours from? I got mine from rc-toy-shop.
It is also my first CP heli, had a FP hummingbird before but never flew well.
I just figured for the $ you can't go go wrong. I would hate to spend 600 to 1g on a tRex and crash it the first day.
