Carl Goldberg Products MATRIX 40 EXTREME 3-D ARF User manual

1
Congratulations on your purchase of the Matrix 40 Extreme 3-D ARF. This is a very unique dual-
purpose aircraft, capable of flying any FAI pattern sequence with ease, while exhibiting remarkable
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 compo-
nents have been provided to allow for 3D set-up while maintaining adequate mechanical advantage
to eliminate flutter. It is you responsibility as an advanced pilot to fly the aircraft in an intelligent man-
ner. THROTTLE MANAGEMENT IS A MUST!!!!!!! Carl Goldberg Products has flown the Matrix 40
through a very rigorous flight-testing schedule and have stressed the airframe beyond all practical
parameters without a single failure. Carl Goldberg Products will NOT warrant the Matrix 40 against
flutter due to improper set-up or excessive speed maneuvers. having said that, we believe you will
find the Matrix 40 to be one of the most responsive, in-the-grove aircraft on the market. The Matrix
40 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.

We are very proud of the construction of the Matrix 40 and all of our other ARF aircraft. Each air-
craft 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, 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 devel-
op 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.
Important Information
Covering coming loose is not COVERED UNDER WARRANTY. Due to temperature 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.

Before beginning assembly of your Matrix 40,
we highly recommend that you study this manu-
al in its entirety. You should begin planning your
radio installation based on your choice of
engine and equipment from the beginning, as
space is limited within the fuselage of the
Matrix 40.
Because the Matrix 40 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 mod-
eling career you will be able to produce a first
class aircraft.
Building supplies needed
Hobby knife w/#11 blades
Thin CA
Medium CA
Canopy glue
30 minute epoxy
Thread lock
Diagonal wire cutters
Pliers
Assorted drill bits
Various sized screwdrivers( both Phillips and
standard head)
Tape measure
Dry-erase marker
Paper towels
Rubbing alcohol
1. Begin construction by locating the fuselage,
wing, wing bolts, washers, and the horizontal
stab. Using a #11 blade, remove the covering
from the stab location at the rear of the fuselage.
2. Insert the stab into the slot and center using
a tape measure or ruler to measure from the
fuselage side to the tip of the stab.
3. With the stab centered, measure from one tip
to the back of the wing cut out. Move stab until
this figure is the same on both sides.

4. When satisfied with the alignment, use a dry-
erase marker to draw a line on side of the stab,
top and bottom where it meets the fuselage.
Remove stab from opening.
5. Using the #11 blade, remove the covering on
the top and bottom of the stab between the
lines. Cut about 1/8” inside the lines so that
there is no exposed wood when glued in place.
Be careful to cut only the covering and not into
the wood of the stab as this would weaken the
stab.
8. Insert the stab into the fuselage one more
time before gluing and check alignment with
wing. Wing and stab should be parallel. When
satisfied with alignment, remove stab. Mix some
30- minute epoxy and apply to stab opening in
fuselage and to bare balsa on the stab. Re-
insert stab into fuselage and check alignment
using all previous methods. Wipe away any
excess epoxy using rubbing alcohol and a paper
towel. Use masking tape to maintain alignment
while glue dries.
6. Using the #11 blade, remove the covering
over the rear wing bolt holes on the top of the
wing.
7. Turn the wing over and remove the covering
over the wing bolt holes. Slide the front wing
dowels in to the holes in the fuselage saddle.
Push down on the rear of the wing till it sits in
the fuselage. Using two wing bolts and washers,
screw the wing down to the fuselage.

1. While the epoxy dries on the stab, mount the
control horns on the elevators. Align on the
inside edge of elevator on the bottom side, with
the holes on the horn aligned over the hinge line.
Use a square to check alignment of holes over
hinge line, this is important to maintain even
throw on both elevators. Use a long drill, piece of
wire, or pencil to mark the holes through the con-
trol horn. Remove the horn and drill the holes
using a 5/64” drill.
Mount the horns to the elevators using the 2-56
x3/4” bolts and the nylon plates on top of the
elevator.
2. Install the e-z hinges in the stab using a pin
in the center of each to make sure they stay
aligned.
3.Install the elevators on the hinges and with the
elevators pushed tightly against the stab,
remove the pins. Using thin CA, glue each hinge
in place by applying two to three drops on each
hinge. Have the elevators deflected to full up
when gluing the bottom side of the hinges and
deflected to full down when gluing the top side
of the hinges. This will insure that you can get
full throw later.

3. Place tailwheel on the bottom of the fuselage
so that the wire is flush with the back of the
fuselage and centered on the bottom.
Drill two 1/16” holes in the location of the
two mounting holes and install the tail wheel
using the 2mm screws.
6. Locate the rudder horn 5” from the bottom
edge of the rudder on the left side. Mark the
holes and drill using 5/64” drill as was done with
the elevator. Mount the horn using the 2-56 x 1”
bolts and nylon plate. Twist the control horn so
that it is facing the rudder servo hole.

4. Mark the location of the tail wheel wire on the
rudder and drill a 5/64” hole into the rudder to
accept the tail wheel wire.
5. using pins to center the hinges as was done
with the elevators, install the rudder.
Deflect to full throw and glue the hinges in place
using thin CA.

Elevator Bellcrank
Elevator Bellcrank
1. Locate the elevator bellcrank hardware.
3. Locate the center tiller arm and the two 2-56 x
29” threaded rod with two nylon clevis.
Install the tiller set screw into the tiller arm.
Thread the nylon clevis onto each of the rods
then snap the clevises to the center tiller arm.
Push the center tiller arm through the fuselage
towards the tail starting at the radio compart-
ment.
2. The aluminum shaft has a hole on one end,
make sure that the hole size is 3/32” by using a
drill in the hole. Install one of the control arms
on the end with the hole using a 2mm screw.
The screw should go all the way through the
arm.

5. Install the shaft through the mounts by first
putting a washer, then the ball shaped
bearing,and inserting in one side. You must
then install the tiller arm on the shaft as it pass-
es through the fuselage. On the other side install
the ball shaped bearing, another washer and
then the other control arm. You must now mark
the location of the hole on the aluminum shaft
and drill a 3/32” hole to accept the 2mm screw.
Install the screw through the shaft and into.
Rotate the shaft so as both control arms point to
the bottom of the fuse. Through the access hole
on the bottom of the fuse. Center the tiller arm in
the fuselage and tighten the set screw. (See
Drawing on top of page 8)
6. you can mount the hatch cover on the bottom
of the fuselage using clear tape or screws (not
included)
open hole
4. Using your #11 blade, open the hole on both
sides of the fuselage. Install the mounts in both
sides using the 2mm screws supplied. There is
an access hole in the bottom of the fuselage for
installing the plate on the inside.
Note: You may need to make the hole slight-
ly larger. Use a dowel with sand paper to
help open the hole. Do not open the hole
more than required.
7. Center the elevator servo in the tray and
mount the servo using the hardware supplied
with the radio.
Place the elevator pushrods on top of the servo
arm.
8. Making sure that the elevators are level, mark
the outer hole location on the pushrods and
make a 90 degree bend.
9. Insert the pushrods through the bottom of the
servo arm and install the nylon swing in keepers.
Cut off the remainer of the wire so 3/8” is show-
ing.

11. Locate the two 2-56 x 10” elevator pushrods
and thread a clevis on each. Install the clevis on
the elevator horn and mark the location of the
bend at the bellcrank. Bend the rod 90 degrees
and cut to a length of 3/8”.
12. Install the elevator pushrod using the two
short nylon swing in keepers on the bellcrank
end.(Don’t forget to use the silicone retain-
ers)
Rudder Servo
1. Remove the covering over the rudder servo
cutout with your #11 blade. It is just above the
elevator bell crank hole on the right side of the
plane.
2. Install the rudder servo using the hardware
supplied with the radio. You will need an 18”
extension added to the servo lead.
3. Locate the 2-56 x 10” pushrod and thread a
clevis on the end.(Don’t forget the silicone
keeper) Install a servo arm on the servo and
center the servo. The servo arm should be
positioned pointing up parallel to the rudder
hinge line. Mark the location for the bend and
make a 90 degree bend. Cut off at 3/8” and
install in the servo arm using the swing in nylon
keeper to retain it. The hole in the servo arm
will need to be drilled to a 5/64”.
