"This game is a simulator, there is no "overpowered or underpowered" more realism is good."

Exactly! People think of this as Battlefield, but it's not! It's arma, and arma is a game when you see a tank, you know you're screwed!

Still able to reproduce the problem. Same as before

If you want to fix it, add all the controls for heli to the options menu. In this example we need to change the "helifast foward" option, but we can only do that in the config and not in-game!

Well to fix it, you just have to put in a button which has the "Fast foward" option in the "controls" menu?

But i am trying it now

fixed it... went into my profile config and deleted the: heli_fastfoward (or something like that) so went from:
heli_fastfoward: "18"
to
heli_fastfoward: ""
