It took longer than I would have ever believed, but I finally have the fuselage ducting for my oil cooler and one of the two radiators completed.  The top fabric of the center section looks loose.  There is no solid structure on the top ribs to keep them spaced properly till I rivet the top skin on.  It will be pulled tight then.  The big opening will also be closed up with a section of fabric after the top skin is in place.
