Congratulations on your purchase of the
Protégé 60 ARF. Every effort has been made
to produce a lightweight, straight, easy to
assemble aircraft. Quality hardware compo­nents have been provided, It is your responsibil­ity as an pilot to fly the aircraft in an intelligent
manner. Carl Goldberg Products has flown the
Protégé 60 ARF through a very rigorous flight­testing schedule and have stressed the airframe
beyond all practical parameters without a single
failure. Carl Goldberg Products will NOT

war­rant the Protégé 60 ARF against flutter due to
improper set-up or excessive speed maneuvers.
having said that, we believe you will find the
Protégé 60 ARF to be one of the best trainers
on the market .

We are very proud of the construction of the
Protégé 60 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 Ultra Set™ 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 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 Protégé 60
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.

ADHESIVES & GLUING TECHNIQUES

Ultra Set™ CAadhesives are specially formulated to firm-

ly 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 Ultra Set™ 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 Ultra Set™ CAglue. 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 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 pre­vent Ultra Set™ CA Glue and Ultra Set™ 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 Protégé 60 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.

Use these control throws for the first
flights. Work your way up to more throw
movement when you are comfortable
with the Protégé 60 ARF.

Elevator 7/16” High / 1/4” Low
Ailerons 7/16” High / 1/4” Low

ability.

BALANCING AND CONTROL THROWS

CG Balancing

Balancing the Protégé 60 ARF 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 4” to 4-3/4”. Measure next to the fuse­lage back from the leading edge.
Balance the Protégé 60 ARF right side
up.
