Helicopter Simulation Suggestions

[CCIP]

Sounds like Take On Helicopters might be the title for you: http://takeonthegame.com/

It's not perfect so far from what I hear, but it's getting support, and in terms of look and a mix of both civil and military operations, nice graphics and decent modeling, it's a good balance. You get to fly a range of choppers from military to civilian, and the engine (same as ARMA II all-around military sim) means that you can expect user-created cotnent to be easily available (and creatable). Makes for good single player, from what I gather.

If you want an uber-realistic combat sim, DCS: Black Shark 2 may be the title for you: http://www.digitalcombatsimulator.com/

It's a fair bit more complex and quite retentive in systems/weapons modeling, but if you want to fly a high-tech Russian attack helicopter. You don't get to fly any other units, although it is cross-compatible with DCS: A-10 (separate game) now from what I hear. Good for multiplayer, if what I've seen from our resident flyers here is any indication.

Hope this helps
