ARROW 3D
Instruction Manual.
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.
If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C supplier
and join your local R/C Model Flying Club. R/C Model Flying Clubs offer a variety of training
procedures designed to help the new pilot on his way to successful R/C flight. They will also be able
to advise on any insurance and safety regulations that may apply.

SUGGESTION.
To avoid scratching your new 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
aircraft and to protect the table. Keep a couple
of jars or bowls handy to hold the small parts
after you open the bag.
NOTE.
Please trial fit all the parts. Make sure you have
the correct parts and that they fit and are
aligned properly before gluing! This will assure
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.

5) Remove the stabilizer. Using the lines
you just drew as a guide, carefully remove the
covering from between them using a modeling
knife.
When cutting through the covering to remove it, cut with only enough pressure
to only cut through the covering itself. Cutting
into the balsa structure may weaken it.
6) Slide the horizontal fin into place in the
pre-cut slot in the rear of the fuselage again.

7) When you are sure that everything is
aligned correctly, mix up a generous amount
of Flash 30 Minute Epoxy. Apply a thin layer to
the top and bottom of the stabilizer mounting
platform sides in the fuselage. Slide the
stabilizer in place and realign. Double check
all of your measurements once more before
the epoxy cures. Hold the stabilizer in place
with T-pins or masking tape and remove any
excess epoxy using a paper towel and rubbing
alcohol.

INSTALLING THE RECEIVER AND BATTERY.
1) Plug the servo leads and the switch
lead into the receiver. You may want to plug
an aileron extension into 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) Do not permanently secure the receiver and battery until after balancing the
model.
4) Using a 2mm drill bit, drill a hole through
the side of the fuselage, near the receiver, for
the antenna to exit.

JOINING THE WING HALVES.
1. Locate the aluminium wing dihedral
brace.
2. Test fit the dihedral brace into each
wing half. The brace should slide in easily.

ARROW 3D
INSTRUCTION MANUAL.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located95mm 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 smoothness 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 .
Secure
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.
BALANCING.
1) It is critical that your airplane be balanced correctly. Improper balance will cause
your plane to lose control and crash.

2) Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them
on the top side of the wing95mm back from
the leading edge, at the fuselage sides.
3. Turn the airplane up side down. Place
your fingers on the masking tape and carefully lift the plane .

CONTROL THROWS.
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.
Rudder : 30mm right 30mm left.
Aileron Control
PRE-FLIGHT CHECK.
1) Completely charge your transmitter and
receiver batteries before your first day of flying.
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.
