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 1-678-450-0085.
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 surfaces.
Allow to dry for 10 minutes before flexing
the aileron.
7.
Repeat the above steps for the other half of
the wing.

2. Unscrew the engine from the motor mounts.
Place the cowl on the fuselage and fasten
using the 4-40 x 1/2” bolts and washers.
Re-tape the clear plastic sheet on the marks
that you made on the fuselage.
Make a mark where the cut out is on the cowl.
remove the cowl and cut out the openings.
NOTE: Start with small openings then slowly
increase the size till the cowl fits.
RECEIVER, BATTERY & SWITCH
Install your radio switch.
Install your receiver and battery pack accord-
ing to your radio instructions.
The Sukhoi has lots of room to move the bat-
tery around to help with the CG. Do not make a final place till you have balanced the plane.
We placed our receiver behind the rudder
servo and our battery in front of the throttle servo. The location of these items will vary with each planes set up.

Throws
We have provided two sets of throws. Use the lower throws on the first flights then work your way up to the higher throws. Do not use the higer throws till you are ready.
LOW HIGH
Elevator 1” UP& Down All you can get Ailerons 1/2” Up & Down All you can get Rudder 1-1/2” Right & Left All you can get
When you have gotten comfortable flying the Sukhoi slowly increase the throws while still staying within your flying ability.
The Sukhoi was designed around a
1.20 four-cycle engine or a .90 two-cycle engine both of these engines will give you excellent performance. Remember, a bigger engine is not always better. Using a 15-8 to a 16-8 prop works well on these engines.
BALANCING AND CONTROL THROWS
CG Balancing
Balancing the Sukhoi is very important, you might need to use weight depending on the servos and engine that you use. Start out with the balance point at 5”. This balance point is a safe place for you to fly the Sukhoi at. As you get comfort­able you can move the CG back further. The further you move the CG the more wild the aerobatics will become, BUT the more unstable the Sukhoi will become.
For your next aerobatic A R F, try the Ultimate Bipe.
