Virtual cockpits ar not like 2D panels. Some are similar, in that the gauges are "projected" onto an invisible screen (wher some gauge movement is possible).. But most are "cookie-cutter".. meaning each gauge has its own invisible polygon.
I've never experimented with the deafult C172.. but it sounds like its the latter.
Quote:this should be in panels, you could model in some knobs though, (im not the one to ask about modeling though)
You can't do anything to the model, without access to the model's source file.
