Section three and four of the bottom sheeting are molded in the same manner as the first two. Balsa holds shape very well once it is dry. Once I removed the dry sections from the fuselage, I trimmed the edges to make nice seams. This is difficult as prior to having the sheeting glued on, the stringers and formers have a bit of flex. As you try to hold the parts into their final position to test the fit, you distort the structure with the pressure of holding them in place. It may look beautiful has you hold everything together, but when you take your hand away, everthing springs back into place and your seams open up. This is exactly why I keep large tubs of filler on hand.

Electrical tape was not required at the balsa sticks I used to hold the edges down while gluing are covered with a layer of clear packing tape. Easy mold release! The syringe technique also made for much cleaner seams.
