The best FS2004 can do is the "Advanced 206" Jetranger from Dodosim:

Flightsim is fun and good for procedures/nav but feels "dead" compared to the real world....
My understanding is that DodoSim has improved the flight dynamics simulation of FS 2004. So when you mean "dead", would that mean, it is also unrealistic (their web site looks like they have made improvements like "Vortex Ring State", "loss of tail rotor effectiveness", etc.)
