Figs. 102 to 109. Details of Collapsible Monoplane
The two centre ribs are shaped as shown in [Fig. 104]. It will be seen that the leading edge is raised ¼ in. above the fuselage, and the rear edge is level with it. The ends of the ribs are fitted into small holes drilled in the top of the fuselage, and kept in position by means of small metal clips, as shown in Figs. [105] and [106]. Four of the clips are required, and they may be easily made from thin tinplate and soldered. The ribs should be soldered to the trailing edge so as to make them secure. The framework should be covered with proofed silk, and neatly glued on all edges.
