Application of the Rudders.
The figures given also include the expense of rudders, but the
details of these have not been included as the glider is really complete
without them. Some of the best flights the writer ever saw were made by
Mr. A. M.
Herring in a glider without a rudder, and yet there can be no doubt that
a rudder, properly proportioned and placed, especially a rear rudder, is
of great value to the aviator as it keeps the machine with its head to
the wind, which is the only safe position for a novice. For initial
educational purposes, however, a rudder is not
essential as the glides will, or should, be made on level ground, in
moderate, steady wind currents, and at a modest elevation. The addition
of a rudder, therefore, may well be left until the aviator has become
reasonably expert in the management of his machine.
