Toavoidscratching your new airplane, donot
unwrap the pieces until they are needed for
assembly. Cover your workbench with an old
towel or brown paper, both to protect the air-
craftandto protect the table. Keepacouple of
jars or bowls handy to hold the small parts af-
ter you open the bag.
Pleasetrial fit alltheparts.Makesure youhave
the correct parts and that they fit and are
alignedproperlybeforegluing!Thiswillassure

from natural materials, every plane is unique
andminor adjustments may have tobe made.
However, you should find the fit superior and
assembly simple.

INSTALLING THE AILERON SERVOS.
Bottom side.
 1) Install the rubber grommets and brass
eyelets onto the aileron servo.
Because the size of servos differ, you may
need to adjust the size of the precut opening
in the mount. The notch in the sides of the
mount allow the servo lead to pass through.
2) Place the mount onto the wing haft,
aligning the cut out in the mount with the cut-
out in the wing. The two notches in the mount
should face the leading edge of the wing.
 3) While holding the servo mount firmly in
place, trace around it using a pen.
4) Remove the mount, and using a model-
ing knife, carefully remove the covering from
inside the outline you drew.

mount, withtheoutputshafttowards the lead-
ing edge of the wing, using the wood screws
provided with your radio system. Drill 1/16”
pilotholes through the mount before installing
the screws. This will prevent the wood from
splitting.

Blow through one of the lines to ensure
the fuel lines have not become kinked inside
the fuel tank compartment. Air should flow

 3. Turn the airplane upside down. Place


1) It is critical that your airplane be bal-
anced correctly. Improper balance will cause
your plane to lose control and crash.

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 80 mm back from
the leading edge, at the fuselage sides.
BALANCING.
Accurately mark the balance point on the
top of the wing on both sides of the fuselage.
The balance point is located 80mm back from
the leading edge. This is the balance point at
whichyourmodel should balance foryourfirst
flights. Later, you may wish to experiment by
shifting the balance up to 10mm forward or
backtochangetheflyingcharacteristics.Mov-
ing the balance forward may improve the
smoothnessand arrow-liketracking,but itmay
thenrequiremore speed for take off andmake
it more difficult to slow down for landing. Mov-
ingthe balanceaftmakesthemodelmoreagile
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 youmust add
weigh*tothe nose.Ifthenosedrops, it is“nose
heavy” and you must add weight* to the tail to
balance.
*Ifpossible, first attemptto 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.
