INTRODUCTION

USING THIS INSTRUCTION MANUAL

Before you begin assembling your SUKHOI ARF, take
some time to read through this entire instruction book. It
is designed to take you step-by-step through the process
and to give you added information on engine and radio
selection and set-up, balancing your aircraft, and flying
your model. The time you spend will speed the assembly
process and help you avoid problems.

PREPARING FOR ASSEMBLY

You will need a work area of approximately 24 x 70" which has
been covered to protect it from adhesive, as well as cuts and
other damage. Many people cover their work area with a
sheet of dry wall (sheet rock) and/or waxed paper t o pre­vent CA Glue and Epoxy from ruining the work surface.

CONSTRUCTION TIPS

IMPORTANT: ALWAYS READ A FEW STEPS AHEAD.
This will alert you to coming instructions and will help you
plan accordingly.

Using the Parts Identification section, familiarize yourself
with the various items included in your kit box.

As you work, CHECK OFF EACH STEP in the box provid­ed, so that you are sure you do not forget anything.

Do not hesitate to ask questions. Your local hobby dealer
and area flyers will most likely be happy to help, as they
want you to have a successful flying experience. You may
also receive technical assistance from Carl Goldberg
Products, Ltd. by telephone [phone].

ADHESIVES & GLUING TECHNIQUES

CA adhesives are specially formulated to firmly glue the
plywood, hardwood, and balsa used in your model and to
withstand the vibration and stresses of high performance
flight. However, there are times, such as when you are
installing the stabilizer and fin on the fuselage and want
more set-up time for careful alignment and positioning,
then you should use epoxy.. Occasionally, you also will
want to use thin CA, which "wicks" into the surrounding
areas. Aliphatic resin glue or similar water-based glues
can also be used, but they will add to the assembly time
because they dry so much more slowly than CA glue.
Remember, when ever using any CA, you must be care­ful to read instructions thoroughly, as you will have only
seconds for positioning of parts. Be sure to trial fit parts
together before gluing. Also, never use watery THIN type
CA glue for gluing plywood and hardwood parts. Thin
CA's do not adequately bond these areas.

CAUTION

Some people may experience an allergic reaction when
exposed to fumes from CA glue or epoxy. As with paints,
thinners, and solvents, it is always important to use glues
only where there is adequate ventilation to carry fumes
away. A fan is recommended. Also, special care must be
taken when using CA, as it will bond skin as well as other
surfaces. Before using any CA, carefully read all label
precautions. When using CA, protective eye-wear and
care in keeping the glue away from the face is highly rec­ommended. If CA does happen to get into the eye, hold
lid open and flush with water only. Seek immediate med­ical attention.

COVERING

The SUKHOI ARF is covered in a premium polyester film
chosen by many of the world's top flyers for its beauty,
toughness, and ease of application and repair. It is not
uncommon for ARF's to develop a few wrinkles in transit.
If this is true of your model, the situation is easily correct­ed. Before you begin putting the pieces together, run over
the surface of each section with an iron (either specially
designed for airplane use or the more cumbersome
household iron) or use a modeling heat gun. Apply the
heat (set at about 350° F), following along with a soft cloth
and pressing down on the covering as you go around.
This will more firmly set the covering adhesive into the
wood and keep your aircraft covering tight and smooth in
the future.

One of the great advantages of polyester film is that it can
be applied over itself without causing gas bubbles. This
allows you to repair your aircraft, as well as to customize
it in a number of ways. If, due to a flight mishap, you get
a hole or similar covering damage, simply trim away the
ragged edges and then apply a patch, following the direc­tions that come with your covering , which is available at
your hobby dealer.

Important

Information

Covering coming loose is not COV­ERED UNDER WARRANTY. Due to
temperature changes the plane may
develop some wrinkles in the cover­ing that you will need to remove
with an iron. Be sure to seal the
edges down first so that you do not
cause the covering to shrink and
leave exposed areas of wood.
Please inspect the plane before
beginning to assemble to make
sure you are happy with it. After
assembly has begun you cannot
return the kit. If you find a problem
before beginning to assemble the
plane you must contact us, please
do not return it to the dealer.

2.  Locate the pre-cut aileron hinge slots in both

wing halves. Using a hobby knife (#11 blade),
slide the blade into each slot to make sure it
is cleanly cut.

 Repeat this process with the ailerons, mak-

ing sure all hinge slots are clean.

3.  Place a straight pin into the center of each of

the four CA hinges.

 Slide each hinge into the hinge slots on one

of the wing halves. The pin will prevent the
hinges from going further than halfway into
the wing.

 Slide the aileron toward the wing until no

gap remains between the aileron and the
wing.

5.

 Carefully check the alignment of the aileron.

It should be centered, with about 1/32" on
either end.

 When satisfied with the alignment, remove

the straight pins, being sure to keep the
aileron tight to the wing. You may wish to
apply a few pieces of masking tape to keep
the pieces in place.

6.  Keeping the aileron and wing in position,

apply 3 or 4 drops of CA glue to the small
exposed area of each hinge.

 Turn the assembly over and again apply 3

or 4 drops of CA glue to the exposed hinge

IMPORTANT! To ensure that any connections locat-

ed inside the wing will not come loose, either when
the wires are pulled, or during flying, always tape

them securely together with electrical tape.

4.  Making sure to use the correct servo for the

opening, attach the servo wire to the12"
extension and securely tape the connection.

 Push the extension wire into the wing until it

comes out the hole near the center of the
wing.

5.

 Grasping the extension in the hole, SLOWLY

pull until the end of the 12" extension comes
out of the hole.

 Tape the extension securely to the wing, so

that it will not slide back in while you are work­ing.
