ovignaud22, I see that the first two responses to your request for assistance were totally worthless, (which it seems is becoming a theme lately). However, nedyob, kicked in some really good info.
You can't forget the grand daddy of all graphics providers for custom RC Airplane graphics. I've used them for years and they will do your graphics however you wish. I've talked with them both on the phone and via e-mail and have always gotten what I wanted/needed. Kirby Custom Graphics, at
http://kirbysgraphics.com/ and their phone number is 513-932-2422.
Good luck with your project.
