2) If all the decals are not precut, please
use scissors or a sharp hobby knife to cut
the decals from the sheet. Please be cer-
tain the model is clean and free from oily
ngerprints and dust. Position decal on
the model where desired, using the pho-
tos on the box and aid in their location.
1) If all the decals are precut and ready to
stick. Please be certain the model is clean
and free from oily ngerprints and dust.
Position decal on the model where de-
sired, using the photos on the box and aid
in their location.
APPLY THE DECALS.
BALANCING.
1) It is critical that your airplane be
balanced correctly. Improper balance will
cause your plane to lose control and
crash. THE CENTER OF GRAV-
ITY IS LOCATED 100MM BACK
FROM THE LEADING EDGE OF
THE WING AT THE WING ROOT.
2) Mount the wing to the fuselage. Place
a piece of masking tape on the top of
each wing 100mm back from the leading
edge at the wing root.
3) With the model inverted, place your
ngers on the masking tape and carefully
li the plane. is is the point at which
your model should balance for your rst
ights. Later, you may wish to experiment
by shiing the balance up to 10mm
forward or back to change the ying char-
acteristics. Moving the balance forward
may improve the smoothness and ar-
row- like tracking, but it may then require
more speed for take o and make it
more dicult to slow down for landing.
Moving the balance a makes the model
more agile with a lighter and snappier
”feel”. In any case, please start at the loca-
tion we recommend.
With the wing attached to the fuselage,
all parts of the model installed ( ready to
y), and empty fuel tanks, hold the mod-
el at the marked balance point with the
stabilizer level.
*If possible, rst attempt to balance the
model by changing the position of the
receiver battery and receiver. If you are
unable to obtain good balance by doing
so, then it will be necessary to add weight
to the nose or tail to achieve the
proper balance point.
Li the model. If the tail drops when
you li, the model is “tail heavy” and you
must add weight* to the nose. If the nose
drops, it is “nose heavy” and you must
add weight* to the tail to balance.
