So, let me get this right, there are two posters complaining that with all their wisdom and experience of virtually flying Helicopters in different games (BF Helicopters are nothing like the real thing, they were dumbed right down for ease of use) they feel that BIS have got it wrong?
Arma II is not perfect, though the helicopter flight model is fairly accurate. This is expected from a 'jack of all trades' simulator rather than a specific flight /infantry /vehicle simulator.
What is actually being complained about is the actual realistic way a helicopter flies, it is obvious that you have not experienced a realistic helicopter flight model, other than DCS Black Shark, and that helicopter is an exception, in its typical Kamov co-axial rotor design it uses a rudder control surface which allows for higher manouverability at speed.
The problem is not with the flight model in Arma II, it is with your misunderstanding of an accurate flight model through the experience of games rather than simulators on the whole.
Take time out and clock up some hours in the editor and give the helicopter some respect and assume you do not know it all and you will be all the more satisfied when you master it.
Learn, adapt and enjoy.
