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 120MM BACK
FROM THE LEADING EDGE OF
THE WING AT THE WING ROOT.
2) Mount the wing to the fuselage. Using
a couple of pieces of masking tape, place
them on the top of the wing 120mm 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.
Accurately mark the balance point on
the top of the wing on both sides of the
fuselage. The balance point is located
120mm 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 .
