The Raven is a great airplane to model.
The Raven art isn't all that difficult and there's plenty of photos available. Look on line. I guess you're thinking the bird graphicxs and Oracle. Correct?
I provide graphicxs and masks, but I can also supply art, or line drawings on paper. I'm in the process of moving, but if you're in no immediate hurry, I could possibly help you with the line art. Could possibly provide vinyl graphicxs also, cuz once the art is made the rest is simple, the vinyl cutting machine just follows the line.
You would have to assist. I would need measurements of your model and a wing/fuselage outline. All this will help in making the art look more like the actual aircraft.
