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
65MM
BACK
FROM THE LEADING EDGE OF
THE WING AT THE WING ROOT.
3) With the model inverted, 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 top of the wing
65mm
back
from the leading edge of the wing at the
wing root.
Accurately mark the balance point on the
top of the wing on both sides of the fuse-
lage. The balance point is located
65mm
back from the leading edge of the wing at
the wing root. This is the balance 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 fly-
ing characteristics. Moving 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 lighter and snappier
”feel”. In any case,please start at the lo-
cation 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.
