I mounted the header tanks on the vertical cage behind the pilot and copilot seats as prescribed in the manual. I then plumbed the header tanks up to the fuel feed and vent lines on the main tank using flexible hose so the wings can fold.
One special addition to the header tanks is the "CAUTION:FUEL" stickers on the tanks. This is mostly an aesthetic treatment but will also serve as a caution for anyone unfamiliar with the aircraft as they rummage around in the baggage area. These decals came courtesy of Stacy (the lovely Mrs Catterson) and her home CNC machine. Let me know if you want her to make any for you!
