I come up second version with three 110 inch screen segments each at
60 degrees for a total screen angle of 180 degrees with a radius of
110 inches or a diameter of 220 inches or 18.333 feet

David, the physical screen segments will be broken down into 11.25 or 22.5
degree slices in order to make it more efficient to make parts for.
That's how I did the larger one. The FOV for each projector is completely
under the control of the software. For example, Ivar Hestness' 737
project is using a 225 degree physical screen using 3 projectors that show
75 degree slices of view using un-docked windows. The NThusim gang
recently added a feature to their software that would clip the pixel or
two wide border that appears when an un-docked window in MSFS has the
input focus.
