1. This manual will help you assemble your
Eurofighter Typhoon. Let’s start with the
installation of the main wing panels.
Apply an even coat of 5-minute epoxy to
the root of the wing panel.

2. Press into position on the fuselage side.

3. Check the alignment of the wing with the
fuselage and wipe off any epoxy that
squeezes out. A small amount of rubbing
alcohol on a paper towel works well.

4. Make sure to check the alignment on the
top of the wing to fuselage joint and wipe
off any excess epoxy. Hold in position
until the epoxy sets. Repeat this process
for the other main wing. We recommend
that you epoxy one panel at a time.

4

5. Plug in the Elevon servo and the wing tip
light. Please match the polarity. On the
servo connection, the orange wire
matches with the white wire on the plug
that exits the fuselage.

6. Feed the connected plugs into the
fuselage and carefully push the wires into
the slot in the wing and fuselage.

7. Locate the carbon rod wing reinforcement
and epoxy it in place in the groove on the
bottom of the wing panel.

8. Locate the 2 main landing gear units and
the 8 mounting screws.

5

9. Insert the pushrod wire into the retract
servo as you fit the retract into position
on the wing.

10. Screw the retract into position.

11. Using foam glue or epoxy, apply glue to
the groove for the drop tanks.

12. Position each drop tank and allow the
glue to set.

6

13. Turn the aircraft right side up on its gear.
Locate the vertical fin and plug in the
position light making sure that you match
the polarity (red-to-red and black-to­black)

14. Apply epoxy to the mating surfaces.

15. Push the vertical tail into position and
check for any glue that may have
squeezed out. Wipe off any excess with a
paper towel and a little rubbing alcohol.

16. Epoxy the nose cone in position.

7

17. Locate the canards.

18. Insert canard into tube on side of
fuselage.

19. . Slip the nut onto the shaft inside the
fuselage. The nut works as a spacer. Slip
the control arm onto the shaft with the
control arm pointing down. Snug the
mounting screw to the flat on the metal
shaft.

20. Attach the canard pushrods to the servos
as shown. Make sure that your servos
are in their neutral position.

8

21. Connect your 7-channel receiver to the
servo wires at the rear of the cockpit
opening. These connections are labeled.

22. Left Aileron and Left Vector = Aileron

23. Right Aileron and Right Vector = Elevator

24. Left Canard = Aux 1 (Flap)

25. Right Canard = Aux 2

26. Left/Right Thrust Vector and Nose Wheel
Steering = Rudder

27. Retracts = Landing Gear

28. Throttle = Throttle

29. The battery installs under the canopy and
is held in place with the pre-installed
hook and loop fasteners.

30. Use two 3-cell 3700mAh packs and plug
one each into the two Series Deans
connectors.

31. If you are using a single 6s battery you
will need to make a jumper from a female
Deans Ultra connector in order to make a
complete circuit.

32. Canopy hatch attaches first at the rear
and is held in place by magnets at the
front.

33. A 7-channel computer radio is required
to fly the Eurofighter. The following
instructions are for the Spektrum DX-7
transmitter with the Spektrum AR7000
receiver.

Vector units should move in the same
direction as the Elevons.

NOTE: When the Elevons are in their neutral
position the Thrust Vector Nozzles should be
in their neutral position also. If they are not
you must adjust them mechanically by
screwing or unscrewing the ball link
connector to achieve a neutral position.

49. On HIGH RATES the Elevons should
move 1-1/2" in both directions. The
Thrust Vector units should move in the
same direction as the Elevons.

50. On LOW RATES the Canards should
move 5/8" in both directions. When the
Elevon moves UP the Leading edge of
the Canard should move UP.

13

Flying

We recommend that takeoffs and landings be made on LOW RATES. Initial flights
should be made using LOW RATES until you are familiar with the aircraft. LOW RATES
allow you to fly smooth pattern maneuvers. The jet is very stable with solid handling. On
HIGH RATES with the functioning Canards and Thrust Vectoring turned on, the airplane
can perform amazing maneuvers. High Alpha Harrier flight is easy to steer using the
thrust vector nozzles as your elevator and rudder controls. Flat spins are easily
accomplished using full rudder and up elevator combined with a bit of opposite aileron.
Example: Full left rudder, full up elevator and some right aileron to perform a left flat
spin. Exit the maneuver by neutralizing the elevator and aileron and applying slight right
rudder. This is a larger size model and requires the use of a scale type landing
approach. Set up your final approach with a slight nose high angle of attack and about
1/4 throttle, allow the jet to settle applying a little throttle to arrest the descent and touch
down on the main gear first. Ground handling is superior.

2008 Official Academy of Model Aeronautics National Model Aircraft Safety Code

GENERAL

1. A model aircraft shall be defined as a non-human-carrying device capable of sustained flight in the atmosphere. It shall
not exceed limitations established in this code and is intended to be used exclusively for recreational or competition
activity.

2. The maximum takeoff weight of a model aircraft, including fuel, is 55 pounds, except for those flown under the AMA
Experimental Aircraft Rules.

3. I will abide by this Safety Code and all rules established for the flying site I use. I will not willfully fly my model aircraft in a
reckless and/or dangerous manner.

4. I will not fly my model aircraft in sanctioned events, air shows, or model demonstrations until it has been proven airworthy.

5. I will not fly my model aircraft higher than approximately 400 feet above ground level, when within three (3) miles of an
airport without notifying the airport operator. I will yield the right-of-way and avoid flying in the proximity of full-scale
aircraft, utilizing a spotter when appropriate.

6. I will not fly my model aircraft unless it is identified with my name and address, or AMA number, inside or affixed to the
outside of the model aircraft. This does not apply to model aircraft flown indoors.

7. I will not operate model aircraft with metal-blade propellers or with gaseous boosts (other than air), nor will I operate
model aircraft with fuels containing tetranitromethane or hydrazine.

8. I will not operate model aircraft carrying pyrotechnic devices, which explode, burn, or propel a projectile of any kind.
Exceptions include Free Flight fuses or devices that burn producing smoke and are securely attached to the model aircraft
during flight. Rocket motors up to a G-series size may be used, provided they remain firmly attached to the model aircraft
during flight. Model rockets may be flown in accordance with the National Model Rocketry Safety Code; however, they
may not be launched from model aircraft. Officially designated AMA Air Show Teams (AST) are authorized to use devices
and practices as defined within the Air Show Advisory Committee Document.

9. I will not operate my model aircraft while under the influence of alcohol or within eight (8) hours of having consumed
alcohol.

10. I will not operate my model aircraft while using any drug which could adversely affect my ability to safely control my model
aircraft.

11. Children under six (6) years old are only allowed on a flightline or in a flight area as a pilot or while under flight instruction.

12. When and where required by rule, helmets must be properly worn and fastened. They must be OSHA, DOT, ANSI,
SNELL or NOCSAE approved or comply with comparable standards.

RADIO CONTROL

1. All model flying shall be conducted in a manner to avoid over flight of unprotected people.

16

2. I will have completed a successful radio equipment ground-range check before the first flight of a new or repaired model
aircraft.

3. I will not fly my model aircraft in the presence of spectators until I become a proficient flier, unless I am assisted by an
experienced pilot.

4. At all flying sites a line must be established, in front of which all flying takes place. Only personnel associated with flying
the model aircraft are allowed at or in front of the line. In the case of airshows demonstrations straight line must be
established. An area away from the line must be maintained for spectators. Intentional flying behind the line is prohibited.

5. I will operate my model aircraft using only radio-control frequencies currently allowed by the Federal Communications
Commission (FCC). Only individuals properly licensed by the FCC are authorized to operate equipment on Amateur Band
frequencies.

6. I will not knowingly operate my model aircraft within three (3) miles of any preexisting flying site without a frequency­management agreement. A frequency management agreement may be an
allocation of frequencies for each site, a day-use agreement between sites, or testing which determines that no
interference exists. A frequency-management agreement may exist between two or more AMA chartered clubs, AMA
clubs and individual AMA members, or individual AMA members. Frequency-management agreements, including an
interference test report if the agreement indicates no interference exists, will be signed by all parties and copies provided
to AMA Headquarters.

7. With the exception of events flown under official AMA rules, no powered model may be flown outdoors closer than 25 feet
to any individual, except for the pilot and located at the flightline.

8. Under no circumstances may a pilot or other person touch a model aircraft in flight while it is still under power, except to
divert it from striking an individual.

9. Radio-controlled night flying is limited to low-performance model aircraft (less than 100 mph). The model aircraft must be
equipped with a lighting system which clearly defines the aircraft's attitude and direction at all times.

10. The operator of a radio-controlled model aircraft shall control it during the entire flight, maintaining visual contact without
enhancement other than by corrective lenses that are prescribed for the pilot. No model aircraft shall be equipped with
devices which allow it to be flown to a selected location which is beyond the visual range of the pilot.

WARNING – THIS IS NOT A TOY! Radio controlled model aircraft are capable of inflicting serious injury and/or property damage if

not assembled, operated, and maintained in a competent and safe manner. If you are not already experienced with radio controlled

models, we strongly suggest that you find an experienced modeler to assist you.
