Instruction Manual
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.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage.
The balance point is located
64mm
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 experi-
ment by shifting the balance up to 10mm for-
ward or back to change the flying character-
istics. Moving the balance forward may im-
prove the smoothness and arrow- like track-
ing, 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 .
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
64MM
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
64mm
back
from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place
your fingers on the masking tape and care-
fully lift the plane .
BALANCING.
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.
Ailerons : 15mm up 15mm down
Flap : 40 mm
Elevator : 20mm up 20mm down
Rudder : 25mm right 25 mm left
1) Completely charge your transmitter and
receiver batteries before your first day of fly-
ing.
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.
We wish you many safe and enjoyable
flights with your
PZL-124 WILGA.
