Carefully
review how
your
Electronic Speed Control (ESC)
works. Most ESC's
will not power
up the motor until
the
throttle has been reduced
to
zero. Avoid the prop in
case
the
motor suddenly stafts to
turn.
Step 23.1
Consult
your
radio manual for
instructions about
testing and
operating
your
radio system.

BALANCING THE AIRCRAFT
Step
24.1
The
CG
for your J3
PIPER
CUB is located at
2"
to
2-118"
(50
-
55 mm)
back
from the leading edge of
the
wing when the wing has been attached to the fuselage
as
per
illustration 25A.
Step 24.2
For the initial flight, the
CG should
be located at
2" (50mm) back from the leading edge
of
the wing when the
wing has
been attached to
the fuselage.
Step 24.3The CG
is measured with the
motor, battery
and
all
other components
installed.
Step 24.4
Set up
the
CG as it will
be
when you fly
it.
Step 24.5lt
is
very important to have the CG correct.
Flying
your
model
with the CG
too far
back
will likely
lead
to
loss
Step 25.1 Once you have confirmed that the CG
is
correct,
you should do
a
thorough review of the entire model before
your first flight. Check everything twice! Every hook
up,
every coupling, everything! Do
it twice!!
Step
25.2 Before your first flight,
have an experienced flyer
review your work. Do not
fly your model until
it
has
been
checked out by
a
third party
who knows how
to
fly
and how
to set up a
model aircraft. Do not fly
alone. Seek
experi-
,
,
enced
help.
Step
25.3 Once you have completed your
first
flight, get
in the
habit of checking
your
model over before and after each flight!

have
assembled your
model and installed your radio,
motor and
battery that the CG of your model is
incorrect
you
must
bring
the CG to the correct location by doing the
following
BEFORE
FLYING
:
-
Move the battery pack fore or
aft
-
Do not add weight to correct the CG. Move
components
& especially
your
battery pack rather than add
weight.
Only
add weight
as
a
measure of last
resort.
