Since you've shown your age; allow me to be frank because leafer is out of town. Get the Ka-50. Once you've mastered its flight characteristics, you'd want a stable platform to blow shit up. Sure, the Huey and the Mi-8 can also blow shit up but the Ka-50 gives you radar guided shit to blow shit up with. That is why Kamov gives you that altitude hold button, so you can giggle and gasp when shit gets blown to smithereens in your little monochrome monitor.
Now about it being stable, once you've achieved stable in DCS, all it means is you have already crashed many, many times. There's no shame in that. I still cannot do an ass-up landing on the P-51D, and I've had it since released. Nothing that carries the DCS label will give you instant gratification. You just can't get in any of the DCS aircraft and expect to geek out with loops and rings while popping pimples like you could with x-plane and msfs.
Pretty much what I said. :D
