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 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, etc.

Mounting Stab Before beginning assembly of your Matrix 40, 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, 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.

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. 4. When satisfied with the alignment, use a dryerase marker to draw a line on side of the stab, top and bottom where it meets the fuselage. Remove stab from opening. 8.

Control Horns 2. Install the e-z hinges in the stab using a pin in the center of each to make sure they stay aligned. 2-56 x 3/4” SCREWS CONTROL HORN PLACE CONTROL HORN AT HINGE LINE SNAP LINK 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.

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. 5 inches 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.

open hole 6. you can mount the hatch cover on the bottom of the fuselage using clear tape or screws (not included) 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 slightly larger. Use a dowel with sand paper to help open the hole. Do not open the hole more than required. 7.

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”. 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. 12. Install the elevator pushrod using the two short nylon swing in keepers on the bellcrank end.

Landing Gear and Wheel Pants The pants are just alike except for this mounting pad. drill a 5/32” hole into this mounting pad, 1/4” up (or into the bottom of that pad) from the bottom edge and centered on the wheel opening. Note: The wheels provided are good for asphalt run ways but not for some grass fields. Use a 23/4” wheel for grass run ways. You might have too open the bottom of the wheel pants more. 1. Locate the landing gear and bolt in place using the four 3mm x12mm bolts and flat washers.
PAGE 13
Engine Mounting 4-3/4” Note: The distance that is shown is for using a Carl Goldberg spinner. If you are going to use a different spinner, the front of the cowl needs to be 4-5/8” from the firewall. 1. Locate 2- motor mounts 4- 4mm x25mm bolts 4- flat washers 4- lock washers 4- blind nuts. 4- #6 x 3/4” Screws 3. Place you engine in the mounts and adjust till the prop washer is 4-3/4” from the firewall. Clamp the engine in place and and mark the location of the mounting holes. Drill using a 7/64” bit.
PAGE 14
Fuel Tank 5. Align the motor on the firewall. Center the engine on the off center vertical line and the horizontal line. Drill holes on the marks using a 3/16” drill. Insert the blind nuts into the rear of the fire wall and tighten using washers and lock washer (use thread lock). 6. Drill a 9/64” hole in the firewall in position with the throttle arm. Insert the 3.25mm nylon sleeve in the hole. Install an e-z connector in the throttle arm and install the 1.25mm x50cm pushrod.
PAGE 15
3. Install the tank in the fuselage in the notches provided in the bulkhead, and hold in place with foam(not provided). Attach the fuel lines(not provided) to the three metal lines and route through the hole in the firewall and to your engine. If you are using an engine without a pump or pressure system you will probably have to mount the tank in the nose of the plane. 2. After all the cutouts are made in the cowl, you can use the same method to mount the cowl.
PAGE 16
Canopy Decal Location 1. Locate the canopy and trim to the scribe line. It is a good idea to trim about 1/8” outside the line at first and then trim to fit so as not to get it too small. 1 Clean model surfaces thoroughly before applying decals. 2 Cut decal sheets apart in sections, as needed. Fold decal in half, front to rear. Open at fold and lay decal out straight. The protective backing will bubble away from the decal at the fold.
PAGE 17
The Elevator This maneuver has your plane drop vertically in a nose high attitude, depending on wind conditions any where from a 45 degree angle in low wind to almost backwards in higher wind conditions. To perform it, at a high altitude with high rates on, pull your throttle back and feed in the elevator until you have the full high rate applied. Use the rudder to guide the plane, and adjust attitude with minor throttle inputs.
PAGE 18
The Waterfall This maneuver has your plane flipping around the axis of the wing, while dropping. Starting from a high altitude, go to low throttle and gradually pull the nose up to near vertical. Just when the plane is about the stall, give it full down elevator and full power. Make attitude corrections with the rudder and ailerons to keep the plane flipping on axis. Cut the throttle and hold full down elevator as the plane flips around to nose high again, add power to flip it over again.
