Did I miss a step in the build? It was interesting to walkaround a factory built Kitfox. Of course, everything look familiar but I'm jealous of the nice tight join at the wing tips. One detail that I noticed was aluminum trim pieces that close the gap above the door frame. I've flipped through the online build manual but don't see where this part is installed and I haven't done it on my project. Am I missing something or is this a factory special?
