Helos are their own bit of fun. They are harder to fly and more expensive than airplanes, but flying one will make you a better airplane pilot.

I'm not at all familiar with the chopper you mention, or any of the current helos for that matter. A guy at my field has an electric chopper that flys very well. I know he replaced the stock motor with a brushless. His crash costs aren't very high, since less tends to break when something goes wrong with it.

However, in helos as well as planes, bigger flys better in many ways.
