Flipped over the fuselage to start the prep and covering of the bottom. Funny how when you do something like and and change the perspective of how you are looking at stuff you find more to do while it's flipped. I installed the avionic trays that go behind the panel, the header tank drain, the transponder ground plane and then, finally got to lay the skin over the bottom. Traced out all the fuselage points that I will glue the skin to and have started brushing on the glue.
