The elevator is a miniature edition of the main plane, being 13 in. in span and provided with a chord of 3½ in. The camber is ⅜ in. at the centre and ³/₁₆ in. at the tips. It is attached to the framework in the following manner: Two straight pieces of thin bamboo 5 in. long are attached to the under-side of the elevator, and run parallel to the tapered end of the fuselage, and the projecting ends of these pieces are attached to the frame with elastic bands. To give an increased angle, blocks of wood are placed under the bamboo strips as shown in [Fig. 125], these pieces being ¼ in. high. A greater or less angle may be given by moving the blocks either backwards or forwards as required.
