Hey  everyone , i am new by the way  i would like to ask you guys how do you change the textures of an airplane i mean ive been trying downloading , loads of textures files trying to copy and pasting it into the airplane textures file and still dosent work , can someone please give me an advise (FSX version).  !

It will help to have a preliminary understanding of the "aircraft.cfg" file that each and every model uses. It's found in the main folder for each airplane. You can look at existing aircraft in FSX and study the files. Also, load the FSX SDKs. It's a separate installation found on FSX Disk 1. Microsoft gives away all their trade secrets there, and explain in detail how the aircraft.cfg file works.

Secondly, if you want to do your own repaints, you will need DXTBmp (http://www.btinternet.com/~mnwright/programs/dxtbmp.htm). It's the link at the very bottom.
