OK...I am really confused, I mean really confused.  I put the 727_100_4_T texure file and only that file in the texture folder.  On the top of the wing I placed the registration number.  When I loaded the sim the registration number appeared on both sides (mirrored) which means it was backward one of the wings.  Bare in mind that the APU port was also showing on both wings, but it doesnt show on both wings in any of the default paints.  So that lead me to believe that the sim is using the same texure for both sides.  But how can that be?  The defaults have different wings identified by the APU port only showing on the right hand side?  I then renamed the file to 727_100_5_T and the APU port disappeard from the left side but the registration number stayed? Say what?  Anybody painted a wing before so you can tell me what I am doing wrong or is it the paint kit/model set  up wierd?
