This instruction manual is designed to help you build a great flying aeroplane. Please read this
manual thoroughly before starting assembly of your ARROW 3D . Use the parts listing below to
identify all parts.
WARNING.
Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it is
capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU
ASSUME ALL RISK & RESPONSIBILITY.
IfyouareinexperiencedwithbasicR/CflightwestronglyrecommendyoucontactyourR/Csupplier
and join your local R/C Model Flying Club. R/C Model Flying Clubs offer a variety of training
proceduresdesignedtohelp the newpilotonhiswaytosuccessful R/C flight.Theywillalsobeable

To avoid scratching your newairplane, 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
aircraftandto protect the table. Keepacouple
of jars or bowls handy to hold the small parts
after you open the bag.
Pleasetrialfitall the parts.Makesureyouhave
the correct parts and that they fit and are
alignedproperlybeforegluing!Thiswillassure
proper assembly. ARROW 3D ARF is hand
made from natural materials, every plane is
unique and minor adjustments may have to
be made. However, you should find the fit
superior and assembly simple.
The painted and plastic parts used in this kit
are fuel proof. However, they are not tolerant
of many harsh chemicals including the
following: paint thinner, C/A glue accelerator,
C/A glue debonder and acetone. Do not let
these chemicals come in contact with the
colors on the covering and the plastic parts.

4) Using a2mm drill bit, drill ahole through
the side of the fuselage, near the receiver, for
the antenna to exit.
 1) Plug the servo leads and the switch
leadintothe receiver. You may want to plug
anaileronextensioninto the receiver to make
plugging in the aileron servo lead easier
when you are installing the wing . Plug the
battery pack lead into the switch.

2) Wrap the receiver and battery pack in
the protective foam to protect them from
vibration. Use a rubber band or masking tape
to hold the foam in place.

 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
100MM 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 100 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
balancepointis located 100mm backfromthe
leadingedge.This isthebalancepointat which
yourmodelshouldbalanceforyourfirstflights.
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
moredifficulttoslow 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 modelis “tail heavy” and you must add
weigh*tothenose. If thenosedrops,itis“nose
heavy” and you must add weight* to the tail to
balance.
*Ifpossible, first attemptto balance themodel
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 measured
at the widest point of each control surface.
 3) Check to be sure the control surfaces
move in the correct directions.

Ailerons : 20mm up 20mm down.
Elevator : 20mm up 20mm down.

 1) Completely charge your transmitter and
receiverbatteries beforeyour firstdayofflying.
 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.
