The Christmas holidays were a great distraction from building. I did make progress but it was sporadic.
Lots of small jobs including sloshing and installing the fuel tanks, #2 rib and lower false ribs. My biochemist daughter explained why sloshing acetone and gasoline releases a gas and quickly builds pressure but I was too overcome by fumes to remember the details. The #2 ribs and false ribs were fairly simple.
Kitfox does offer an optional banjo fitting for the fuel line. The photo shows how little material had to be removed from the rib so the finger strainer can be cleaned in the future.
Used plenty of Hysol when installing the piece of trailing edge between ribs #1, 2 and 3. Then, when it came time to install the reinforcing flaperon brackets on the ends of those ribs, it took lots of careful work with a Dremel to remove the rock hard epoxy.
