cause your plane to lose control and
crash. THE CENTER OF GRAVITY IS LOCATED 75MM 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
75mm 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 .
Li the model. If the tail drops when
you li, 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, rst 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.
75 mm
Accurately mark the balance point on
the botttom of the wing on both sides of
the fuselage. e balance point is located
75mm 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 balance forward may improve
the smoothness 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 .

1) Completely charge your transmitter and receiver batteries before
your rst day of ying.
2) Check every bolt and every glue
joint in the ISPORT to ensure that
everything is tight and well bonded.
3) Double check the balance of the
airplane. Do this with the fuel tank
empty.
4) Check the control surfaces. All
should move in the correct direction
and not bind in any way.
5) If your radio transmitter is
equipped with dual rate switches double check that they are on the low rate
setting for your rst few ights.
D) Check the throttle. Moving the
throttle stick forward should open the

E) From behind the airplane, look
at the aileron on the right wing half.
Move the aileron stick to the right.
e right aileron should move up and
the other aileron should move down.

switch on your transmitter to change
the direction.
We wish you many safe and enjoyable ights
with your ISPORT.

An out of balance propeller will cause
excessive vibration which could lead
to engine and/or airframe failure.
