This clip is actually just 3DoF. If you turn off Pitch, Yaw and Roll in the tracker, you have the same result in IL2. If you also use [KeyPad 0] to toggle "Zoom View" to off, you don't get into a zoom by moving too far forward, so you can use the [Delete], [End] and [PageDown] keys to zoom.

Downside? You can't follow aircraft around the sky with your head or check your six.
