(8/23/03) Progress report
I finished the structure of the left wing today! The right wing lacks rip caps and tip rib but should soon be finished. I started covering the underside of the fuse in anticipation of the installation of the wing center section, when I expect it will not be so easy to flip upside down. I think I'll have the airframe structure complete before the leaves fall. That will give me the winter to cover, install engine and control system. Think spring:-)
5/9/2004 Both wings are covered and have one coat of latex paint. Vstab, rudder and hstab are covered and waiting for paint. I've decided that I will probably pull off the less-than-perfect fabric I had originally put on the fuselage and redo it. The 3M Fastbond 30NF contact cement works great. Check out the link for a step-by-step description of the covering process.
