Bad Company 2

Push 4 for tool/defib, if I remember right.

For helli the default is to use your mouse to go backwards/forwards and W/S for up/down.

Make sure you invert mouse for flying, makes life a lot easier, W go up, push the mouse forwards and you nose down and move forwards, you bank the chopper moving the mouse left and right and use the A and D keys to turn left or right using the rudder. A combination of mouse and rudder helps your turn faster. Use S to decend. Your gunner gets a laser tag on the r-click to paint tanks with, once locked on use the pilots r-click to launch a guided missile.

Last time I tried the mouse wasn't working too much, first thing I tried.  
Try again now.

u dont need to invert, by default moving moving ur mouse down will make the nose descend in turn the heli mvoes forward.

edit down as in forwards XD

I see most many people get in, take off and fly backwards - me too.  
Pushing the mouse forwards instead of backwards.
Thanks, I'll try as soon as I can.

Do you need specialization for the defribs & fixy tool, if so; where can I equip 'em?

Defib comes as standard, along with the repair tool (number 4? on engineer / medic). Quite fun to kill people with as well  

defib come in after a certain lvl. it might be 5 idk.

Right I got it:
Defrib. & Repair tool is unlocked pretty quick so I got the fixy.  
The heli.s on my default control is using WASD & the arrow keys with no use of mouse unless gunning. - is there a chopper that the pilotr can gun?
thanks.  

yes there are, some maps have apaches and other similar types, that allows misssiles to be hailed from the driver seat.
