Instruction Manual
WING ATTACHMENT.
Wing bolt.
Insert.
Secure.
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
weigh* 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.
3. Turn the airplane upside down. Place
your fingers on the masking tape and care-
fully lift the plane .
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
110-115MM
BACK FROM THE LEADING
EDGE OF THE WING.
2) Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them
on the top side of the wing
110-115mm
back
from the leading edge, at the fuselage sides.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located
110-115mm
back from
the leading edge. 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. 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. Mov-
ing the balance aft makes the model more agile
with a lighter and snappier ”feel”. In any case,
please start at the location we recommend .
