You probably know the aircraft models! There are white devices on which we place our companies, this system is called Repeindre. Some sites like JetAbout and Norrebo provide an excellent template, but at Norrebo they can not use a template because they do not have transparency! so you can not use them with Microsoft Paint. JetAbout offers only a few transparent models.
My idea of the day is to create my own completely transparent models so that the most null people can use them.
AIRBUS
A300-600
A300-600CF
A330-600F
Other templates after.
