I learned, sorta, on a HBK2 and I deff. find the larger birds much easier to fly, well I guess I mean hold in a steady hover. Big helis are MUCH more stable!!! The HBK2 is very quick, to the point of being very UNsteady, but it really is not. Once you are used to its attatude it is very cool!!! I've built a very blinged out all CF and every upgrade there is for it so I could have one bad mother in my fleet. It is soooo fast that I really need to slow it down before it is flyable. For someone who is a good pilot I think the HBK2 would be one of the most fun helis going. I can see that some day I will be doin nothin but grinning from ear to ear while flying it. BUT till then I really think a larger heli is better to learn with.
