The coaxials are not real helicopters because it has 2 smaller motors driving 2 counter spinning rotors. I think the setup waste power and you also need a extra motor at the end to push the thing around. I would rather have those that has only 1 rotor that can fly out door, but of course even harder to fly.

But still 2 motors for the 2 rotors and therefore I think still waste power on the extra weight and gear. Also 4Ch is more expensive too.

I saw one in LD for $99, but it is still a 3Ch.
