In placingthe planes or wings on the backbone or motorbase have the inside edges about fifteen inchesapart. With the two planes, each ten inches indepth, this will make the aeroplane thirty-fiveinches in length, or about one yard. It should be remembered all the aeroplanemodels here suggested and illustrated are farfrom being perfect. The science of aviation isstill very young, and the best we can do at pres-ent is to experiment with all sorts of models, andso gradually develop the best form. The greataviators, the Wright brothers, Curtiss, andothers, admit very frankly that their aeroplanes
