Added the cabin wires. Must say feel a bit silly after the tri stock affair. I remember why. I was focused on the joint between the nose frame and the main frame. They are simply attached by epoxy of 2 5/16 balsa sticks on either side and thus just lost track of the firewall. Now that I have the cabin wires installed it seems much more stout. May yet consider fibre-glassing the interior, especially at that joint. Stay with me
