Nothing yet, but thinking of making up some pilot name or AMA number decals I can put on my stuff.
That or else work on some stencils and buy airbrush equipment. I've got enough hobbies and not enough raw artistic ability, so I'll likely stick with the decal option.
Can also use some Rc-Help decals for things (will take some measurements for sizes I need).
I'll work things up in Illustrator and let you know.
