Yesterday I made my throttle cable and ran it through the firewall. Nothing particularly interesting to report here. Very straightforward. Just one item of note, the instructions never actually say to run the wire through the sheathing. I guess that would seem obvious. But if the wire and sheathing are in separate bags not near each other it might confuse someone. So I am mentioning it.

I installed the under carriage skin. I was worried that the leading edge of the skin is the lowest point on the plane bottom so it might catch some wind and before I attached the skin I could see light up through the bottom. I was worried about air getting in there. And creating noise. So I added some firewall insulation above the skin to stop drafts.
