I think the pulleys look great and add some interest, overscale maybe, but in there, I doubt even noticeable. I have built two of these and can't answer your camera question either, but; in my opinion, the location of the camera in a back area, wouldn't be seen anyway. I like the seat the way it is and the fuel tank turned out nicely, again, hardly noticed once buttoned up. A word of caution, the lower wing will droop unless you rig it with dihedral. When you get to that stage use a strong rigging line on the inner bay to lift that wing into a slight dihedral. I will be following along as you go. Have fun.
