It is hoped that this book will help the reader achieve a better visual picture of what occurs during the free flight of his miniature aircraft. With such an understanding, it will be possible to obtain high altitude and floating glide with ease. And the most important point of all, to know the limits to which the aircraft is capable of performing with safety and so keep it in the air where it belongs, instead of making it bite the dust.
