This weekend I was working on a flight sim I’m building for my dad. We opted to use the Optoma GT1080. The screen is 21″ from the front of the cockpit. The projector is 42″ away from the screen and is mounted 95″ off the ground. Also, because of distance of the short throw (not ultra short throw) I don’t actually have the cockpit itself centered on the screen–the cockpit is slightly to the left of center, else you could see the edges of the screen. The projector itself is centered horizontally to the screen. The projector mount we built is at ~25 degree angle with shims to adjust the tilt. He didn’t want to mount the projector into the ceiling, hence the mount built onto the cockpit itself. I think we may revise this so that it sits unattached to the cockpit so that movements of the flight controls don’t vibrate the projector.
