The Ka-60 easily passes 300 km/h in normal level flight, and can go up to 400 km/h. It also accelerates ridiculously fast, making it hard to attack ground targets at slower speed.

Engine upgrades that make a 300 km/h design hit 400 km/h in less than 10s? Unlikely.
Personally I really dislike arguments like "It's 2035, let's move away from reality as we know it and just take a wild guess as to what improvements might exist." There could just as well be lazer-weapons on gunships...
For me in sustained level flight with the ka-60 with zero wind and 23% overcast at 15m above the sea the top speed is ~ 305kph repeatable in all 4 principle directions consecutively negating existence of wind factors etc.
The speed of aircraft is given for level flight based on an ISA day and is seldom the same as Vne (Never exceed speed – the speed YOU must never exceed), but there are a couple of military helicopters today with Vne >190kts (352kph) and even over 216kts (400kph) and there have even been a couple of helicopters that have been proven to fly >400kph in level flight (modified Lynx) not just over short distances but over 15km and 25km distances of sustained level flight.
You should also remember in A3 you in essence have maximum take-off power available at all times, whereas in real life maximum take-off power is normal duration and duty cycle limited and that many helicopter have far more power from their engine/s than you could hope to use in RL at sea level, as it is there to deal with altitude (physical vs. density), so you still have the same performance at e.g. a 6000ft take-off as with 0ft take-off.

Yes but those were special editions with upgraded engines, lightened fuselage and otherwise edited for speed record.
Instead Mi-24 (A-10) still maintains the speed record for attack helicopters of 368km/h on extended range and can get 330-350km/h speed depending weapons load and does it carry infantry or not.
Still every helicopter in ARMA III reach high speed way too fast, they as well turn and bank way too fast.
And it is as well little weird that all the reticles point to direct flight direction causing that player can not fly helicopter slowly forward and fire weapons without gaining huge acceleration.
Example in ARMA II the problem with KA-50 and KA-52 were that helicopter is capable to "hover" while staying in different directions or banking heavily. But it is not capable to work that way in it as it gains quickly speed.
And if talking about 2035 year attack helicopters like KA-60 it should have helmet aiming for minigun so player could just look freely littlebit different directions (20 degree to side and up directions, 35-45 degree to down what would give a pilot/gunner change to aim little better. Of course AH-9 should have static weapons and rely to its agility and light attacks.
If helicopters would accelerate, turn, bank and take off slower I think it would make them more believable than just easy and fast transport.
Now it is just too easy to do 360kph > 0kph deacceleration to do a infantry drop and then leave the zone after few seconds quickly accelerating to max speed to flee from situation.
vryoffbtdrummr, then you should try it out before thinking its not possible, maybe in a dive of 15 or less grades downside you can reach 300 km/h pretty fast.
I agree, deacceleration its unrealistic, but one of the ArmA weak points is the unrealistic flight physics, mods like ACE, or things like (if they add it) the TOH way to fly choppers will change that

Yes that's true. However, when executing a return to target maneuver, the speed well exceeds 300 km/h after the turn. (like this http://www.youtube.com/watch?v=lRJYu9clZF0) This makes it hard to aim accurately.
BTW, about never-exceed speeds, the Ka-60 in game can exceed 500 km/h *at sea level* without spinning out of control after a dive.
