Thanks for the information. I will continue to learn C++ , Lua, and Gizmo. Flight Simulation programs have come along way and I know it has a bright future. As a real world pilot it always amazes me at how real the controls, cockpits and scenery look in xplane. Do you feel that there is a market for programmers in the simulation world or do most do it as a hobby? I enjoy programming so my plan is to dive into it and learn as much as I can.
