Good start. I stopped using the dremel for sanding when I sanded way to much off a couple of times.
Are you planning on making it with the cockpit open or just in flight like I did with mine in the workbench section page 34?
I painted my Zentraedi/Zentran emblems on. With the first Regult release Capt made some emblems that you had to printout and are too scale. I cut out the shape and taped them on to the right spots and painted. I attached the image for you.
