I think you can, they allow us to change repaints, gauges, cockpit poster and more  ;)

Hope so. But there a lot of files involved - Cfg-s, Effects, Textures, Lightmaps, gauges xml-s and so on, plus some preparations have to be done before. So there no way just to post "How-to guide".
Only way a see - the bunch of files to download. I'm not sure that CS will agree if I do so.

But anyway - there still a lot of things to do and figure-out.
Be patient, but stay tuned! :)
