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
175MM
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
175mm
back from the leading edge, at the
fuselage sides.
3)
Turn the airplane upside down. Place your fingers
on the masking tape and carefully lift the plane.
Accurately mark the balance point on the top of the wing
on both sides of the fuselage. The balance point is
located
175mm
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
1)
We highly recommend setting up a plane using the
control throws listed.
2)
The control throws should be measured at the
widest point of each control surface.
3)
Check to be sure the control surfaces move in the
correct directions.
Control throw Ailerons:
Low: 12 mm up / down.
High: 14 mm up / down.
Control throw Flaps:
Mid: 25 mm down.
Control throw Elevators:
Low: 8 mm up / down.
High: 10 mm up / down.
Control throw Rudder:
Low: 25 mm left / right.
High: 30 mm left / right.

PRE-FLIGHT CHECK
1)
Completely charge your transmitter and
receiver batteries before your first day of flying.
2)
Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3)
Double check the balance of the airplane.
4)
Check the control surface.
5)
Check the receiver antenna. It should be fully
extended and not coiled up inside the fuselage.

6)
Properly balance the propeller.
