this kit out of the reach of younger children, as it contains parts that could be dangerous. A radio­controlled model is capable of causing serious bodily injury and property damage. It is the buyer's
responsibility to assemble this aircraft correctly and to properly install the motor, radio, and all other
equipment. Test and fly the finished model only in the presence and with the assistance of another
experienced R/C flyer. The model must always be operated and flown using great care and common
sense, as well as in accordance with the Safety Code of the Academy of Model Aeronautics
(www.modelaircraft.org). We suggest you join the AMA and become properly insured prior to flying
this model. Also, consult with the AMA or your local hobby dealer to find an experienced instructor in
your area. Per the Federal Communications Commission, you are required to use only those radio fre­quencies specified "for Model Aircraft."

Hot Stik ARF

2

Congratulations on your purchase of the Hot
Stik ARF. 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 your respon­sibility as an advanced pilot to fly the aircraft in
an intelligent manner. THROTTLE MANAGE-
MENT IS A MUST!!!!!!! Goldberg Models has
flown the Hot Stik ARF through a very rigorous
flight-testing schedule and have stressed the
airframe beyond all practical parameters without
a single failure. Goldberg models will NOT

war­ranty the Hot Stik ARF against flutter due to
improper set-up or excessive speed maneuvers.
having said that, we believe you will find the
Hot Stik ARF 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 Hot
Stik ARF 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, Firewall, 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 re-shrink 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 Hot Stik
ARF, 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 Hot Stik ARF 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.

CONSTRUCTION TIPS

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

COVERING

The Hot Stik 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.

Fuselage Assembly

2.  Locate the holes in the bottom of the fuselage

just ahead of the wing opening. Remove cov­ering with an x-acto knife or soldering iron.

3.  Mount the wheel on the axle using the 5\32”
wheel collar.

4.  Find the center of the stab at the trailing edge
and make a mark at the location. Place the
stab on the fuselage and align the center mark
at the rear. Use a straight pin to hold in place.

6.  Using a pencil, make a mark along the side of
the fuselage on both side of the stab.

7.  Using an x-acto knife or razor blade, remove
the covering inside the line you marked. Cut
about 1/16” inside the line so bare wood will
not show after gluing in place. Be careful to
cut just the covering and not the wood as cut­ting into the wood will weaken the stab.

8.  Locate the two elevator halves and the eleva-
tor joiner wire. The elevators should be
installed before installing the fin.

5.  Measure the stab to make sure it is square
with the fuselage. Dimensions X-X should be
the same and stab will be square.
