Worked on the center fuselage where the wing spar passes through. F704 is a big part that carries most of the loads of the aircraft. It's a cool part because it comes anodized or alodined, I'm not sure which. There isn't much fabrication, just some holes to match drill and a few holes to enlarge for grommets. The plans tell you that the hole in the 2nd picture is going to need to be modified, but this looks like a little much. I'll email vans and see what they say. The final picture is me playing a little and wanting to see big parts come together. The practical bit I got from this was to see where to drill holes for wire passes since I really don't like where the plans have you drilling.
