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 72MM 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 side of the wing 72mm
back from the leading edge of the wing at
the wing root.
3) Turn the airplane upside down. Place
your ngers on the masking tape and
carefully li the plane .
Accurately mark the balance point on the
top of the wing on both sides of the fuse-
lage. e balance point is located 72mm
back from the leading edge of the wing at
the wing root. is is the balance point
at which your model should balance for
your rst ights. Later, you may wish to
experiment by shiing the balance up
to 10mm forward or back to change the
ying characteristics. Moving the bal-
ance forward may improve the smooth-
ness and arrow- like tracking, but it may
then require more speed for take o and
make it more dicult 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 location we recommend .
