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
100 MM
BACK
FROM THE LEADING EDGE OF
THE WING AT THE WING ROOT.
3) With the model upright, place your
fingers on the masking tape and carefully
lift the plane.
2) Mount the wing to the fuselage. Using
a couple of pieces of masking tape, place
them on the bottom side of the wing
100mm
back from the leading edge of the
wing at the wing root.
4) Do not turn plane upside down. Only
low wing models should be turned up-
sidedown for balancing. Remove this
paragraph, it is not intended for use in
the instructions. it is a note for you.High
Wing models must be balanced upright.
Accurately mark the balance point on
the botttom of the wing on both sides of
the fuselage. The balance point is located
100 mm
back from the leading edge of
the wing at the wing root. This is the bal-
ance point at which your model should
balance for your first flights. Later, you
may wish to experiment by shifting the
balance up to 10mm forward or back to
change the flying characteristics. Mov-
ing the balance forward may improve the
smoothness and arrow- like tracking, but
it may then require more speed for take
off and make it more difficult to slow
down for landing. Moving the balance aft
makes the model more agile with a light-
er and snappier ”feel”. In any case,please
start at the location we recommend .
With the wing attached to the fuselage,
all parts of the model installed ( ready to
fly), and empty fuel tanks, hold the model
at the marked balance point with the sta-
bilizer level.
Lift the model. If the tail drops when
you lift, 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.
*If possible, first attempt to balance the
model by changing the position of the re-
ceiver battery and receiver. If you are un-
able 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.
