CHAPTER XIII.
AEROPLANE MODELS.
Aeroplane Models are small sized aeroplanes. They may be divided into four classes:
A. Small models of large machines, made for the purposes of construction.
B. Small models of large machines made for the purpose of flying as kites.
C. Gliders.
D. Self-propelling models.
It will be seen at a glance that this chapter should be expanded into a book by itself. Mr. Collins has written an excellent book, "The Second Book of Model Aeroplanes", on the subject, and I hope the readers of this book will look it up, as it will be worth while. In dealing with the subject in this chapter we can not go into it very deeply and not many plans can be given, but we will try to touch here and there some of the important features of construction.
I have grouped the model aeroplanes into four divisions, but before we proceed it will be well to notice the various classes of large machines. There is the monoplane or one plane type; the biplane or two planes, one above the other; and the multiplanes in which several planes are used. The first two have survived, and form the very large percentage of all that are attempted these days. I should like to make clear that I do not recommend, even discourage, any attempt at gliders large enough to carry the maker, and the aeroplane in which a motor engine is to be placed. There is too much danger connected with them, and our lives and limbs are too precious a gift to be trifled with in such unnecessary ventures. The little models, however, are harmless and yet are very fascinating, even when there is no thought of their embodiment in a large machine.
In group A, where the worker seeks to imitate a large machine in miniature, the joy of the undertaking lies in the processes involving very accurate work and nicety of finish. There is a fascination for young people in the making of things in miniature. The models made
