USING THIS INSTRUCTION MANUAL
Before you begin assembling your Shock 3D 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 motor 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 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 pre-
vent 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.
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. via e-mail (questions@carlgoldberg-
products.com) or 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 sec-
onds 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 pre-
cautions. When using CA, protective eye-wear and care in
keeping the glue away from the face is highly recommend-
ed. If CA does happen to get into the eye, hold lid open
and flush with water only. Seek immediate medical atten-
tion.
COVERING
The Shock 3D 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 correct-
ed. 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 air-
plane 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.
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 direc-
tions that come with your covering , which is available at
your hobby dealer.

Information
Covering coming loose is not
COVERED UNDER WARRANTY. Due to tem-
perature 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.
