Things to Be Considered.
In laying out plans for a flying machine there are five important points which should be settled upon before the actual work of construction is started. These are:
First—Approximate weight of the machine when finished and equipped.
Second—Area of the supporting surface required.
Third—Amount of power that will be necessary to secure the desired speed and lifting capacity.
Fourth—Exact dimensions of the main framework
and of the auxiliary parts.
Loose Joint Connection Device.

Fifth—Size, speed and character of the propeller.
In deciding upon these it will be well to take into consideration the experience of expert aviators regarding these features as given elsewhere. (See Chapter X.)
