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
88MM
BACK FROM THE LEADING EDGE OF
THE WING.
2)
Mount the wing to the fuselage. Using a cou-
ple of pieces of masking tape, place them on the
top side of the wing
88mm
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 bal-
ance point is located
88mm
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 charac-
teristics. 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
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: 25 mm up / down.
High: 25 mm up / down.
Control throw Elevators:
Low: 25 mm up / down.
High: 25 mm up / down.
Control throw Rudder:
Low: 40 mm up / down.
High: 40 mm up / down.

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.
