helicopter
closer
to
the
obstacle/object
until
you
hear
and
see
the
corresponding
servo
respond.
This
will
give
you
an
approximate
indication
of
how
well
a
particular
obstacle/object
can
be
detected.
However,
the
actual
distance
of
detection
and
the
corresponding
response
when
flying
will
vary
depending
on
the
factors
previously
noted
(in
the
‘C.A.T.
Functions
and
Performance’
section).
NOTE:
You
may
notice
that
the
servos
seem
to
‘twitch’
when
testing
the
function
and
performance
of
C.A.T.
without
flying.
This
is
normal
and
to
be
expected
as
a
result
of
the
high
performance
and
sensitive
nature
of
the
technology.
Gain
Trimmer
Pot
The
C.A.T.
module
is
equipped
with
a
‘GAIN’
trimmer
pot
that
can
be
used
to
adjust/fine
‐
tune
the
overall
‘sensitivity’
and
response
of
the
technology.
This
pot
is
set
at
the
factory
to
provide
good
performance
overall
and
does
not
typically
need
to
be
adjusted.
However,
you
can
remove
the
C.A.T.
module
from
the
body
or
make
a
small
hole
in
the
windshield
to
access
the
pot
and
use
a
small
‘straight’
blade
screwdriver
(preferably
with
a
plastic
tip)
to
adjust
it.
If
you
ever
find
that
the
helicopter
‘twitches’
when
the
technology
is
activated
(turned
on)
and
there
are
no
obstacles/objects
within
the
detection
range
of
the
sensors,
you
should
decrease
the
gain
until
the
helicopter
no
longer
twitches:
Turn
the
gain
trimmer
pot
counterclockwise
(
‐
)
to
decrease
the
gain.
In
some
cases
you
can
increase
the
sensitivity/response
of
the
technology
by
increasing
the
gain:
Turn
the
gain
trimmer
pot
clockwise
(+)
to
increase
the
gain.
However,
if
you
find
that
the
helicopter
‘twitches’
in
any
direction
after
increasing
the
gain
you
should
decrease
it
slightly
and
check
again.
C.A.T.
Hints
and
Tips
It
is
typically
best
to
use
the
‘Low
(LO)’
control
rate
setting
on
the
transmitter
and/or
minimal
control
inputs
to
keep
the
helicopter
from
traveling
too
quickly
toward
obstacles/objects
whenever
possible.
If
you
ever
feel
the
helicopter
is
on
a
path/at
risk
to
collide
with
an
obstacle/object
you
can
try
the
following
to
help
ensure
C.A.T.
has
the
best
possible
opportunity
to
automatically
avoid
the
collision:
o
Apply
control
inputs
to
slow
the
helicopter
down
(even
if
you
are
not
able
to
stop
it
completely
just
slowing
it
down
will
give
C.A.T.
the
best
chance
to
detect
the
obstacle/object
and
hopefully
avoid
the
collision).
