space moving physics

hello, im making a space shooter game and im in need of help on how to do some moving physics. just so i dont need to explain everything here is a video of the physics im talking about. (moving, tilting when turning) http://www.youtube.com/watch?v=Ul-MiX1Qge0

here is my code i have

var speed = 3.0;

var rotateSpeed = 3.0;

function Update () { var controller : CharacterController = GetComponent(CharacterController);

// Rotate? around y - axis

transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);

// Move forward / backward

var forward = transform.TransformDirection(Vector3.forward);

var curSpeed = speed * Input.GetAxis ("Vertical");

controller.SimpleMove(forward * curSpeed);

}

@script RequireComponent(CharacterController)

Here's a place to start. *Note it needs some tweaking to get it to work but you'll learn quite a bit through the code:

There is also a 2d spaceship controller here:
