This is a one person cockpit build, you need less room and for my purposes it suites fine. I always fly alone! one person cockpit also allows for a smaller main screen. the footprint is less. 43inch suites me fine. i do not think i will be upgrading to a beamer, or a 55 inch tv any time near. All screens are HD, furthermore, check the hardware i use in my other post.
The image below shows how i did it. i do not claim this to be perfect, it's just how i started the build. I built it from wood, with a roof to make the cockpit experience whole. The total height is 160cm. I sit inside with a normal deskchair on wheels.
