Weight of helicopter

I don't know if this is a bug or just something new I have to get used too but its challenging.

When flying the attack helicopter, if feels totally different than Transport Chopper. The attack chopper feels really heavy and when you lower your altitude very fast, it feels heavy and can't raise altitude at same rate as dropping. leading to a lot of crashes.

Also, the missile detection lock from AA launches and Drivable AA Tanks sound the same as when a guided missile is incoming. I end up popping flairs thinking its a AA missile and its just a guided missile, then I'm instantly vulnerable to AA lock or being painted.
