Well, if this is the case I stand corrected but I cannot imagine the helo behaving like this (and yes I had the overhead knob on 5).
See, this is the problem man. Too often you assume just because you don't think it should be that way that it can't be and thus whatever it is is crap. Real aircraft aren't all P-51's. The 206 responds like it does for a reason, both in the real world and with the Dodosim 206 in FSX. Helicopters are NOT
easy aircraft to fly. If you're not constantly jostling the controls you either have auto stabilization, have the autopilot on, or you're on the ground. When someone tells you that a helicopter is defying aerodynamics and physics to fly, they're not kidding. The whole issue of asymmetric blade lift should make the aircraft theoretically uncontrollable, yet they aren't. They're unique beasts, and nearly impossible to actually replicate in any simulator, including DCS: Black Shark because of this. Dodosim comes very close according to the helicopter pilots I've seen post in non-FS forums about it. But as with anything, how realistic it is really depends more on the equipment you have to fly with than the sim. The sim can be perfect, but because 99% of simmers don't have a floor-mounted cyclic and collective, you can't fly the helos like the real thing and thus adjustments have to be made from the get-go that make it not "feel" right no matter what you do because your control inputs are so much different than how they'd be if you were really flying the helo or were flying it with proper controls.
