Bit by bit, part by part. Each piece has to be found in the great box, then deburred, prepped, then assembled. The tail post has gotten incredibly stiff while still very light. Near the fuselage/cockpit transition, the aileron box has been installed and treated. The battery box was tougher than you would think, what a bunch of weird angles !! What makes the internal fuselage parts so interesting is that they generally share the same rivet holes as the skins, so final installation or just getting everything all line up and tied down will all come at once. Saves on rivets and substructure but sure makes things interesting !!
