[font color = blue]"What is the difference between paint templates for the Lite version and the Reality XP version of the Baron 58?"[/font color = blue]
The only difference between the two is the depiction of the instrument panel in the external aircraft model. Repaints for the Lite version show the Lite version's instrument panel in the external aircraft model, while repaints for the Reality XP version show the RXP version's panel in the external aircraft model.
Otherwise, the repaint templates are the same and, in theory, can be used on either model if you do not mind the external model's instrument panel matching up. Not a big issue in our opinion. ;-)
