GENERAL

a
tricycle

gear.

is
constructed of
heavy,
chrome-
moly-
denum
tubular
steel,
heat

Neoprene

of
magnesium
castings
and
the
six-ply
tires
are
made
by
Good~ear.
The
main
gear
has
a
nine-foot
tread,
which
makes
taxiing
a
simple
orperatioll;
and because of
the
wide
gear´•tread
and
the
aircraft’s
low
center
of
gravity,
taxiing
or
land~g
in
strong
cross-winds
presents
no
problem,
et-en
to
the
novice
pilot.
The
attachin~C
points
of
the
main
gear
are
in
metal
bushings
embedded
in
the
gear-mounting
box
and
attached
to
the
spars.
The
nose
wheel
is
mounted
to
the
cabin’s
tubular-steel
frame
instead
of
the
engine
mount.
The
main
gear
wheels
are
equipped
with
hydraulic
brakes.
The

wheel
rudder
pedal
