To be honest there are too many choices. If I can find a good combo that is truely RTF I'll probably go that route. I looked at one site saying their HDX450 was RTF for $475. As i scrolled down the page it had everything but the motor, tx ands rx. Now to me a RTF is RTF out of the box, not add the motor, TX and RX for another grand. I saw a couple of 400/450 class RTF helis on the RC Heli Universe for sale site. How reliable are these sites? I don't want to buy someone else's wrecked POS.
If I had to piece a 450 class heli together, I'm leaning towards the RC Tec Diable as far as clones go.
