Installation of Motor.

Next comes the installation of the motor. The kinds and efficiency of the various types are described in the following chapter (IX). All we are interested in at this point is the manner of installation. This varies according to the personal ideas of the aviator. Thus one man puts his motor in the front of his machine, another places it in the center, and still another finds the rear of the frame the best. All get good results, the comparative advantages of which it is difficult to estimate. Where one man, as already explained, flies faster than another, the one beaten from the speed standpoint has an advantage in the matter of carrying weight, etc.

The ideas of various well-known aviators as to the correct placing of motors may be had from the following:

Wrights—In rear of machine and to one side.

Curtiss—Well to rear, about midway between upper and lower planes.

Raich—In rear, above the center.

Brauner-Smith—In exact center of machine.

Van Anden—In center.

Herring-Burgess—Directly behind operator.

Voisin—In rear, and on lower plane.

Bleriot—In front.

R. E. P.—In front.
