_Fig. 17. Showing changing angle of body._

THE SUGGESTED TYPE.--In Fig. 18 the suggested
type is shown with the body normally in a horizontal
position, and the planes in a neutral position,
as represented in position 1. When sufficient
speed had been attained both planes are
turned to the same angle, as in position 2, and
flight is initiated without the abnormal oscillating
motion of the body.

But now let us see what takes place the moment
the present type is launched. If, by any error on
the part of the aviator, he should fail to readjust
the tail to a neutral or to a proper angle of incidence,
after leaving the ground, the machine would
try to perform an over-head loop.

The suggested plan does not require this caution.
The machine may rise too rapidly, or its
planes may be at too great an angle for the power
or the speed, or the planes may be at too small an
angle, but in either case, neglect would not turn
the machine to a dangerous position.

These suggestions are offered to the novice, because
they go to the very foundation of a correct
understanding of the principles involved in the
building and in the manipulation of flying machines
and while they are counter to the beliefs of
