Used the DecalPro system to decal the lettering onto the panels. I started with the small control cable panel on the pilot's left hand. The system was a little difficult to get accustomed to. Of the first 10 attempts, only 5 were successful. I had to print more decals, particularly the big ones to get a successful application. After a couple of nights of attempts, I got satisfactory results. These are two of the panels I decaled.
