Toavoidscratching yournew airplane, do not
unwrap the pieces until they are needed for
assembly. Cover your workbench with an old
towel or brown paper, both to protect the air-
craftandtoprotect the table. Keep a couple of
jars or bowls handy to hold the small parts af-
ter you open the bag.

proper assembly. LIBERTYARF is hand made
from natural materials, every plane is unique
andminoradjustments may have to be made.
However, you should find the fit superior and

plugging in the aileron servo lead easier
when you are installing the wing . Plug the

 3. Turn the airplane upside down. Place
your fingers on the masking tape and care-
fully lift the plane .

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
75MMBACKFROMTHELEADINGEDGEOF
THEWING.

2) Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them
on the top side of the wing 75 mm back from
the leading edge, at the fuselage sides.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located 75mm back from the
leadingedge.This isthebalancepointatwhich
yourmodelshouldbalanceforyour 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
moredifficulttoslowdownforlanding.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*tothenose. Ifthenosedrops,itis “nose
heavy” and you must add weight* to the tail to
balance.
*Ifpossible, first attempt tobalance 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) 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.
 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.
