Important Information
Covering coming loose is Not COVERED UNDER WARRANTY. Due to tempera-

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.

a problem before beginning to assemble the plane you must contact us,
please do not return it to the dealer.

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 intelli-
gent manner. THROTTLE MANAGEMENT IS A MUST!!!!!!!! We at Carl goldberg
have put the 30% Ultimate ARF through a very rigorous flight-testing sched-
ule 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, in-
the-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 ele-
vators 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 con-
cerning the assembly and use of the
model.
We expect that you have some build-
ing 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 e-
poxy 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 tow-
els 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.

Take a straight pin and stick through
the blind nut inside the fuselage to
locate the holes for the struts.
Using the four 6-32x3/4” socket
head cap screws, mount the struts to
the top of the fuselage, short ones in
front longer ones in rear. Do not
tighten the screws down tight at this
time. Leave them loose until the top
wing is mounted.
Locate the two I-Struts and the eight
6-32x3/4” socket head cap screws.
The I-Struts are identified left and
right, top and bottom with small
stickers.
Fit the tabs on the top wing between
the brackets front and rear and
install a 6-32x3/4” socket head cap
screw through the holes. Do not
install nuts now.

30% Ultimate ARF
Fit the I-Struts in place paying atten-
tion to left and right and top and bot-
tom. The I-Struts have recesses in
them that fit over the tabs in the
wings. Install the four 6-32x3/4”
socket head cap screws in each strut.
With the I-Struts screwed in place,
install the nuts on the screws that
hold the top wing to the cabanes and
tighten. Install the diagonal braces
using the four 6-32x1/2” socket head
cap screws and 6-32 aircraft lock
nuts. After these are tight remove
the screws holding the struts to the
fuselage one at a time and apply
thread locker. Reinstall and tighten.
This sequence of install and tighten-
ing the bolts will make sure that the
struts are aligned and not under
stress.
