Welcome Juggs
I encourage you to read and re-read various build posts on the forum - it will help you make decisions on the type of pit (simple desktop vs full-size realistic), the flight software (BMS Falcon, DCS, MSFS2020, Prepar3D, etc), the interface system (AIC, PSCockpit, PoKeys, XKeys, etc.) and the display (simple, multiple screens, projectors).
There is no "One-Way" to building a pit. It is completely up to you. We are here to help you. We are all still learning, and constantly discovering new and better ways of upgrading our pits. Welcome to the madness that is Viperpits!
