I have a new SIG Four Star 60 in red that I am very happy about. The one thing that's tough is it's hard to figure out which is right sideup/upside down. Since I've already covered it, are there any special decals that really stand out I could put on the bottom? I'm sure with all the stuff that R/C companies do, they would have one that shimmers in the sunlight or really stands out. Keep in mind this will have to be a decal since I don't want to re-cover.
