Helicopter camera

Hi i have made a helicopter with all the controls but now the camera moves like this

but i want to move camera like this http:/www.youtube.com/watch?v=1svDoLNYdTc

The camera in the second video is just childed to the helicopter: remove any camera script, child the camera to the helicopter and adjust its position in the Inspector (maybe something like [0, 5, -30])

Thanks it works
