I got most of the panels installed today—just a couple to finish up. The panels are held in with Velcro. I added an extra piece or two on several of the larger panels to help them conform to the curvature of the side skins. I used the panels to cut paper templates so I could tell where to stick the Velcro to the skins. All the panels seem to fit quite well—Abby at Flightline Interiors did very nice job.
