Sincraft, You're coming along fine. You shouldn't need your Dremel to sand on the fuselage. Get a large sanding block. That will keep things nice and flat, with no gouges. My sanding blocks are pieces of foam with the paper glued to them with spray on adhesive. They are the full length of a sheet of sandpaper and half the width. I can sand just about everything on a model with them, accept the tightest spaces.
Now all we have to do is get Elad to start building something. He'll never know how satisfying it is until he starts.
