Good results may be obtained by revers-ing this arrangement, as in Fig. 5.

The frame is built likean umbrella, and the whole folds up into a verycompact form. A useful idea may be borrowedhere. By using an old umbrella-frame for thebackbone of your model you may utilize the ribs,which are firmly attached to the frame, and bendthem to form the edges of the planes, the skids,and the braces. The most successful flights, nowadays, aremade by adaptations of the monoplane forms(Fig- 7). The broad V-shape or dihedral angle
