Congratulations on your purchase of the Goldberg Ultimate ARF 3-D ARF.
This is a very unique aircraft, with great 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 your responsibility as an advanced pilot to fly the aircraft in an intelli­gent manner. THR

OTTLE MANAGEMENT IS A MUST!!!!!!!! We at Carl goldberg
have put the 30% Ultimate ARF through a very rigorous flight-testing sched­ule and have stressed the airframe beyond all practical parameters without
a single failure. Carl goldberg will NOT warrant the Ultimate ARF against
flutter due to improper set-up or excessive speed maneuvers. having said that,
we believe you will find the Ultimate ARF to be one of the most responsive, in­the-grove aircraft on the market. The Ultimate ARF excels at high-alpha
maneuvers including Harriers (both upright and inverted), high-alpha rolls,
and high-alpha knife edge. Torque rolls, waterfalls, knife edge loops and ele­vators are all within the performance parameters of this unique aircraft.
Just remember to use common sense when flying this high performance
machine.

BUILDING
INSTRUCTIONS

Before starting to build this kit, we
urge you to read through these
instructions. They contain some
important building sequences as well
as instructions and warnings con­cerning the assembly and use of the
model.
We expect that you have some build­ing experience to take on this model.
This means, every minute detail is not
covered. This is not a basic trainer.
The instructions together with the
simplicity of this kit will allow you to
produce a first class Ultimate .

BUILDING SUPPLIES NEEDED
Hobby knife w/ #11 blade
Thin Zap CA
30 Minute Z-poxy
Thread lock
Wire cutters
Pliers
Drill with bits: 1/8", 5/32", 5/64”

9/64”
Phillips and standard screwdriver
Small clamps
Masking tape
Tape measure
Washable marker
Paper towels
Rubbing alcohol

Begin construction by locating the
two 1/4-20 x 1” socket head bolt used
to bolt the bottom wing on. Put the
bottom wing in place and remove the
covering over the mount holes at the
trailing edge. Bolt the wing down.
Next locate the stabilizer and fit into
opening in fuselage. Check alignment
with wing, it should be parallel when
sighted from the rear. It should not
be necessary to remove any material
to achieve alignment, simply pushing
up or down on one tip should do it. If
necessary remove material from the
bottom of the stab saddle on one side
to achieve alignment.

30% Ultimate ARF

Remove the stab and using a sharp
#11 blade, cut the covering about
1/8” inside the line you drew and
remove the covering. Be careful and
do not cut too deep and cut into the
balsa as this will weaken the stab.
Do this top and bottom. Check the
stab saddle in the fuselage and
remove the covering where the stab
will be sitting. Mix some 30 minute e­poxy and apply to the bare wood on
the stabilizer where you removed the
covering. Slide the stab back into the
fuselage and align using the marks
you made. Use masking tape pulled to
the top of the fin and bottom of the
fuselage to hold parallel to wing.
Use rubbing alcohol and paper tow­els to clean up the excess epoxy.
Recheck your alignment and set aside
to dry.

When satisfied with the alignment,
measure to make sure the stab is
square and centered. Measurement A
should be the same on both sides and
measurement B should be the same on
both sides. When stab is aligned, use a
marker and draw a line on top and
bottom of the stab, on both sides next
to the fuselage.

Top Wing Mounting

Locate the aluminum brackets that
make up the cabane struts. It consist
of six pieces. The two long straight
pieces are the diagonal supports. The
two longer of the pieces with angles
go to the rear and the two shorter
ones go to the front. The sharper of
the two angles are the bottom of the
strut.
