The

are
of
all-metal
con-
struction.
They
are
jig-built, using
hinges
of
machined
extrusions. The
elevator
an
rudder
incorporate
an
unusual
method
of
construction.
The
leading-edge
spar
of
´•these
controls
consists
of
a
specially designed
extrusion
that allows
flush
attachement
of
the
ski~l.
Lead
counterweights
are
provided
for
dynamic
balancing
to
prevent
flutter.
The
control
system
requires
veSylittle
maintenance and
provides
superior
control-
feel,
because
tubes,
rather
than the’conventional
cable
system,
are
used
to
actuate the
controls.
Helm

are
used
throughout
the
controlsystem.
These
bearings
are
simple
and,
dependable
and
require
very
little
maintenance.
