YOUNGSTERS FLY
MODEL GLIDERS
Half a Hundred Boys Ready to
Try for HidalgO Cup at
Auditorium

Final tryouts in the model aeroplane
flying contests to be held by the youth
fuI members of the San Francisco aero
club as a part Of the airship exposition
the Pacific aero club will hold at the
Auditorium Thursday. Friday and Sat
urday were held in the armory in Van
Ness avenue yesterday afternoon. Now
the half hundred boys are ready to fly
their models in the indoor races that
viii give the Hidalgo cup to the one
making the best flights.
Nearly all of the large areoplanes
dirigibles and balloons that viii crowd
the Auditorium have been placed ready
for the opening night, but President
J. c. Irvine has left ample space for
the machines OF Colonel Frank Johnson
and Whipple Hall. Both aeronauts will
be on hand during the three days, and
VIII demonstrate their biplanes. Irvine
and George Kerr, mai gers of the ex-
position, left for San Jose yesterday to
make arrangements for shipping the
aeroplanes from the Garden City avia-
tion field to this city just as soon as
the flights at the rose carnival are
ended
An original monoplane by George H.
Loose, fashioned after the sea gull, will
be shown. Loose has made several
short flights in this machine and hopes
10 have it perfected after a few more
experimental tests.
The 20 foot Santos Dumont mono
plane viii be demonstrated also. This
is the tiniest aircraft known, and yet
1t flies at the rate of 60 miles an hour.
WILL HAMMER AWAY
Tremendous interest has been aroused
in the freak machine an aspiring avia-
tor viii show at the exposition. 1t will
be operated by a motor, and is so ar
ranged that heavy hammer alter
nately rises and falls as the machinery
is in action. This hammer is supposed
to strike a spring which kicks back
and drives the airship into the atmos-
phere. How the aviator, after having
been hammered into the clouds, will
hammer his craft back to earth is not
explained.
This freak bit of mechanics is but
one of score of unusual devices that
viii be on display.
Almost every one OF the youthful
aeronautical enthusiasts of San Fran
cisco gathered together yesterday
afternoon at the armory, Page street
and Van Ness avenue. to experiment
with their home made gliders and mod
els of aerocrafts of every known de-
sign. besides many unknown designs,
which have enlanated from the minds
of the boy birdmen.
Easily the most successful of the
young chaps who will compete at the
meeting to be held in the Auditorium
rink Thursday, Friday and Saturday
nights and Saturday afternoon next, un-
der the auspices of the Pacific aero club.
in yesterdays tests. was Waldemar
Doyal, 120 Buena Vista avenue, who has
a monOplane which he has entered in
classes 2 and 3. While patterned after
no particular known model, the ma
chine of young Doyal proved the in
genuity of it's inventor by making a
fight of 100 feet, the best record set
up by any of the participants at yes
terday's tryout
AN INGENIOUS MACHINE
Another boy who has an ingenious
machine and has spent considerable time
and money in producing a model that
he expects viii bring home one of the
coveted prizes is James Dean. 1860
Union street, who has built a biplane
patterned TO some extent after the fa-
nous Farman, but with what its manu-
facturer considers several vital improve
ments. This biplane will be entered
IN the third and Notifying classes. and
may bear out the hopes Of its inventor.
While ct the present time the motive
power Of the aeroplane is furnished
by powerful elastic bands, 1T is possible
that a miniature motor may be substi-
tuted. which should navigate the small.
frail craft for some considerable dis
tance.
Difficulty in large measure is being
met by the boy flying artists in secur-
ing rubber articles of sufficient purity
and strength to propel properly their
crafts. This defect must be overcome
by the rubber manufacturers and will
undoubtedly eventually call for a new
line Of endeavor in the rubber industry.
THE PRIZE WINNERS
Following are the prizes that will be
given to the successful youths:
Joseph HidaIgo cup-For the most successful
Joseph Hidslgo cup-For the best showing
made by boy under Is years of age.
J. q. POssdas Jr cup-For the best flying fest
made: open 10 boys of all ages.
Oscar Moore cup-For the best ''man carrying
glider.
Pacific aero club-Two cups for special boys
events.
The next and final meeting at which
the entries viii be closed. will be held
Tuesday evening at 700 D. M at the
Auditorium. It is expected that the
boys will turn out in force at this time
and show just what they have done
in the way of subduing the air. Up
TO the present time considerable re-
ticence has been shown. each of the
youngsters feeling that he has the
other fellow beat a little. and that his
ideas viii be stolen and appropriated
by others to their personal use.
