Yesterday, I took a dozen or so pictures of the inside of the fuselage, and today, I mounted the 8.5" x 11" photos on a foam core board. I began drawing some of the various wires and key components that will live under the floor, planning where the wires will go based on their function and how "noisy" or "noise-sensitive" they are.
I also drilled another four or five holes, and installed snap bushings in several bulkheads.
