Instruction Manual

Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 

115mm

 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 smooth-
ness 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 bat-
tery and  receiver. If you are unable to obtain
good balance by doing so, then it will be nec-
essary to add weight to the nose or tail to
achieve the proper balance point.



1) We highly recommend setting up a

plane using the control throws listed.





2) The control throws should be meas-

ured at the widest point of each control sur-
face.





3) Check to be sure the control surfaces

move in the correct directions.

CONTROL THROWS.





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.

PRE-FLIGHT CHECK.

We wish you many  safe and enjoyable

flights with your EXTRA 330L .
