New Invention Is Expected to Put
Plane Within Reach of
Every Family.

The "hylng flivver" has literally and
suddenly come into the sky. Although
the pioneer was wrecked, aeronautic
experts believe that flying fiivyers
soon will become as plentiful, relative
ly, us their namesakes. The new ex-
pertinent In human flight proved itself
before 1t crashed upon Il Jersey tree
in an attempted flight from New York
20 Washington.
The nickname of the Dewoitine
cross between glider and regular
airplane is befitting In respect Of
weight, size, fuel requirements, relative
speed and probable construction cost.
Emil Dewoitine Is quoted as having
said that the machine can and will be
manufactured in quantity at retail
price Of $400. Georges Barbot, the pi-
LOT, has said that the craft would COW
er 125 miles on gallon OF gasoline.
But In respect to practical usefulness,
as a means of aerial transportation OF
persons or goods, the flying fiivver
gives no promise of living up to the
fiivver reputation, In the opinion of
aviation experts.
:. The Dewoltine machine Is different
from a motorless glider chiefly In that
It has a motor. To withstand the VI
bration of the engine, the wing sur
faces and skeletons and the body had
to be constructed more strongly than
in the case of a glider. This meant
additional weight, and, together with
the weight of the motor itself-said to
be only forty pounds-made the whole
craft considerably heavier than gil
der. The total "tsnnage" of the fly
ing flivver was about 400 pounds, with
out the pilot, which is double the av-
erage weight of man-carrying gliders.
And successful man-carrying gliders
have been made weighing even less
than the average of 200 pounds.
The Dewoitine craft is different
from a regular airplane mainly In that
the motor Is Of much lower horse pow
er and the whole machine Is smaller
and lighter. The motor mounted In
the flying flivver Is two-cylinder Cler-
guet of twelve horsepower. Ordl-
nary small airplanes carry 100 horse
power motors, on the average; though
constant improvements in propeller
and wing design are gradually lower
ing the horsepower requisite In pro-
portion to the weight Of machines.
The Sperry fast messenger plane, re-
Gently tested over Long Island, has a
6O-horsepower engine. This plane is
10 hn In fha country
however.
In point of size the Dewoitine in
yention measures 40 feet from wing tip
to tip and IS feet over all In length.
The craft is q monoplane. and even
with the 40-foot spread its wing area
Is less than the average airplane. 1t
is just about equal, however. to the
total wing surface Of many small types
of comparatively high speed one-seater
planes, which have more powerful mo-
tors, weigh much more, but can sus-
tain their weight with the small wings
by virtue Of their swiftness.
Extends Power Of Gliders.
The power equipment Of the flying
fivver, small though II be, is enough
to do away with the limitations pc
culiar to motorless gliders. Its addi-
tional weight, however. Is not too great
to prevent powerless gliding. A glider
cannot start flight from level ground.
Ordinary glider flights are begun from
hilltops, by rolling the craft downhill
until they pick up "fying speed" and
take Off from the slope. Where hill
sides are less steep or long. catapult
devices have been used to help supply
the initial flying speed, but with little
success on the whole. II. J. Nordman
used an elastic rope to propel his sail
plane" into the air from the highest
mound at the golf links near Bayside,
L. l., In n recent series Of flights.
The seemingly impossible feat OF
making motorless winged craft climb
up in the sky is possible because Of
the presence Of upward movements Of
