3. Turn the airplane up side down. Place
your fingers on the masking tape and carefully
lift the plane .
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 GRA VITY IS LOCA TED
70mm 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 70 mm back from
the leading edge, at the fuselage sides.
BALANCING.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 70mm 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. 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
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.
