Atm i use only 2 pc but im working a rebuild on a new cockpit or sim setup with materials i have
Your controls is on both pc and to set it up is not so much work as one might expect.
Just set them both up in yc with the plane of youre choice and save.
Then decide which pc is the server and which is the client (you can always give control or take back control)
But on the client pc it is important to set multiplayer option to off (if not the two planes mix up together and this is weird and annoying)
Than you decide if you set up a direct connection or through server host.
When connection is established you can setup your display
Tthis is something i do not mind doing and for me is part of the fun
A 3 pc would be fun but require another and so for me a 3th licence of msfs and third party plane
which would be crazy not to mention electrical bill and internet.
But you could do this and have another view point like from passenger seat for example and your controls config on third as an observer
Have fun, for there is so much more to do with it
