ATTACHMENT WING-FUSELAGE.
Use the two wing bolts to attach the wing to
the fuselage. Make sure the distance between
a point centered at the rear of the fuselage and
each wing tip. The measurement will be equal
if the wing is aligned correctly. If the measure-
ment is not the same, slightly the hole for the
wing bolts until an equal measurement is
achieved.

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 GRAVITY IS LOCATED
95 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 top side of the wing 95 mm back from
the leading edge of the wing at the wing root.
3) Turn the airplane upside down. Place
your fingers on the masking tape and carefully
lift the plane .

Instruction Manual.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 95 mm 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
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 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 receiver battery
and receiver. If you are unable 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.
