BALANCING.
1)It is critical that your airplane be bal-
anced correctly. Improper balance will cause
your plane to lose control and crash. THE
CENTER OF GRAVITY IS LOCATED 90
MM 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 bottom side of the wing 90mm back
from the leading edge of the wing at the wing
root.
3)With the model upright, place your fin-
gers on the masking tape and carefully lift
the plane.
4)Do not turn plane upside down. Only
low wing models should be turned upside-
down 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 fu-
selage. The balance point is located 90 mm
back from the leading edge of the wing at the
wing root. Th is 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 flying 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 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 stabilizer lev-
el. 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.
