Congratulations on your purchase of the Extra
330ARF. This is a very unique dual-purpose air­craft, capable of flying any FAI pattern
sequence with ease, while exhibiting remark­able 3-D capabilities. Every effort has been
made to produce a lightweight, straight, easy to
assemble aircraft. Because of its oversize con­trol surfaces which are double beveled to allow
for extreme throws, great care must be taken in
the set-up and flying of this airplane. Quality
hardware components have been provided to
allow for 3D set-up while maintaining adequate
mechanical advantage to eliminate flutter. It is
you responsibility as an advanced pilot to fly the
aircraft in an intelligent manner. THROTTLE
MANAGEMENT IS A MUST!!!!!!! Carl
Goldberg Products has flown the Extra 330ARF
through a very rigorous flight-testing schedule
and have stressed the airframe beyond all prac­tical parameters without a single failure. Carl
Goldberg Products will NOT

warrant the Extra
330ARF against flutter due to improper set-up
or excessive speed maneuvers. having said
that, we believe you will find the Extra 330ARF
to be one of the most responsive, in-the-grove
aircraft on the market. Just remember to use
common sense when flying this high perform­ance machine.

We are very proud of the construction of the
Extra 330ARF and all of our other ARF aircraft.
Each aircraft is jig built to insure a straight true
airframe. Every effort is made to build as light an
aircraft as possible. As with any professional
builder, glue is used sparingly. Please take a

moment during assembly and run a bead of
CA or aliphatic resin into the high stress
joints that you can reach such as the landing
gear plate, servo mounting trays, wing hold
down blocks, etc. Also, during the course of

shipping from the manufacturer to our facility in
the United States, it is not uncommon for the air­craft to experience several changes in climate.
This may cause the iron-on covering to develop
wrinkles. This is not a fault of the manufacturer.
Please take a few minutes with your heating iron
and heat gun to iron down the seams and re­shrink the covering where needed. The results
will be a beautiful aircraft with a breathtaking fin­ish that you will be proud to display at your flying
club.

Before beginning assembly of your Extra
330ARF, we highly recommend that you study
this manual in its entirety. You should begin
planning your radio installation based on your
choice of engine and equipment from the begin­ning.

Because the Extra 330ARF is intended for
those with some degree of modeling experi­ence, every minute detail will not be covered.
This is not a basic trainer. Assembly of this air­craft will be easy for the experienced modeler,
and by following the instructions within this
manual and using the skills you’ve gained dur­ing your modeling career you will be able to pro­duce a first class aircraft.

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.

PREPARING FOR ASSEMBL

Y

You will need a work area of approximately 24 x 48" 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.

COVERING

The

EExxttrraa 333300

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
around the edge of the seams first then over the surface
of each section with an iron (either specially designed for
airplane use or the more cumbersome household iron).
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. Once you have ironed the seams
stay away from them with the heat or the covering will
slide when you try to shrink the middle. If this happens the
wrinkles will not come out of the covering.

2.  Locate the pre-drilled aileron hinge holes in both

wing halves. Using a 1/4” drill, drill each hole
1/8” deep. This will allow the center of the hinge
to be inserted half way into each of the surfaces.

 Repeat this process with the ailerons, making

sure all hinges insert half way.

3.  Place 1 drop of oil on each of the hinges at the

center. This is to keep the hinges loose and
prevent epoxy from sticking at the joint.

Caution: Do not get any oil on the length of the

hinge or it will not glue into the surface.

the stab. Then slide the assembly into the
hole in the fuselage till the stab is flush against
the fuse. (The side of the stab with the hole is
the bottom of the stabilizer). Slide the second
stab onto the tube sticking out the other side
of the fuselage. Squeeze both stab pieces
together firmly on to the fuselage.

 Check that the stabilizer is level with the wing.

Shim the tube in the fuselage up or down if
necessary. Do not go any farther till the stab is
level to the wing.

The Stabilizer can be mounted to the

fuselage two ways:

Removable Stabilizer

1.

 Using 4-40 bolt, drill and tap the stabilizer tube

at the hole location. This method will allow
you to remove the stab as needed. CAU-
TION:You must watch the bolt holes for
fatigue and drill another hole by rotating the
tube when this happens.
