The handling with fuels requires circumspective and careful hand-
ling. Imperatively observe the security advices.
-Refuel only if the engine is switched off!
-Take off the body.
-Thoroughly clean the area around the fuels nipple.
-Remove the fuel filler cap and carefully fill in the fuel mixture.
-Smoking or any kind of open fire is not admitted.
-Fuels might contain solvent-like substances. Avoid contact with skin
and eyes. Wear gloves for refueling. Do not inhale fuel vapors.
-Do not spill any fuel. If you have spilled fuel immediately clean the
engine and the model.
-Make sure that no fuel will get into the soils (environmental protecti-
on). Use an appropriate mat.
-Do not refuel in enclosed rooms. Fuel vapors accumulate at the soil
(risk of explosion).
-Transport and store fuels only in admitted and labeled canisters. Keep
fuel out of the range of children.
-The operator is responsible for any damages caused to third persons
in the operating range of the model, respectively of the engine, if they
are injured or in case of property damage.
-The model must only be passed on to persons who are familiar with
this model and its operation, always provide the operating manual.
-Persons with implanted heart pacemakers must not work on running
engines and on live parts of the ignition system when the engine is
being started.
-The engine must neither be started nor operated in enclosed rooms
(without sufficient ventilation).
-When starting the engine, avoid inhaling the exhausts.
-The model must neither be started nor operated without air filter or
without exhaust system.
-Before every start perform a functional check of the safety-relevant
parts.
-The throttle rods must always return automatically to the idle position.
-Any cleaning, maintenance and repair works must only be performed
with the engine being switched off. The engine and silencers are get-
ting very hot. In particular do not touch the silencer.
Comments regarding the construction manual:
Before starting the assembly please see through this construction
manual. This way you will get an overview of the whole execution.
Please check by means of the parts or bag list if the construction kit is
complete and also check the weight of the individual bags for the posi-
tions. Only this way you may be sure that all parts which you need for
the assembly are available. If a part is missing, please immediately
contact your specialized dealer.

As 4WD models have raised steering forces compared
to 2WD models we recommend to use only servos with
metal gear for steering.

Mounting of the rear differential gear
1. Press the ball bearing 12x28x8 on the differential housing.
2. Insert the differential bevel gearwheels in the differential housing as
pictured in position 1. When using the FG mounting tool Item N°.
08505 the inserting of the bevel gearwheels will be eased considerably.
3. Lubricate the diff. driving axles slightly with grease and push them in
the diff. housing.
4. Mount the diff. bevel gear axle. If the bevel gear axle resperctively
the driving axles can only be pushed in severely or if it is impossible to
push them in at any position, you have to disassemble the bevel
gearwheels again and insert them once more.
5. Lubricate the gearwheels slightly with multipurpose grease, e.g. Item N°.
06501.
6. Now press the parts on the diff. housing as described in position 1
and in the given sequence: Steel gearwheel 48 teeth ( consider moun-
ting direction of the slant), rear plastic gear disk 42 teeth, plastic stop
disk right. Fix the complete unit with the M4x40 countersunk screws
and stop nuts M4 (impress the M4 stop nuts in the plastic stop disk
right and use the screw retention high-strength).
Mounting of the front differential gear
1. For mounting of the front differential gear you have to disassemble
the differential from your 2WD model, remove diff. bushing and steel
gearwheel 48 teeth.
2. Now mount the parts on the diff. housing as described in position 2
and in the given sequence: Front plastic stop disk left (consider moun-
ting direction of the slant), front plastic toothed belt wheel 42 teeth, pla-
stic stop disk right. Fix the complete unit with the M4x40 countersunk
screws and the stop nuts M4 (impress the M4 stop nuts in the plastic
stop disk right and use the screw retention high-strength).
3. Push the bearing shafts 6x50mm centrally in the deflection roller
16mm and in the 12-teeth toothed belt wheel.

servo saver) at the inner hole of the servo saver using 2,9x19
pan-head screws as pictured.
4. Disassemble the track
rods of your existing 2WD
model.
5. Mount the track rods
(collar of the joint ball

screws and M4 stop nuts. 1. Impress the tension sleeve for servo saver
from above through servo saver part B and
servo saver part A.
2. Mount the servo saver spring with the
M10 nut on the thread of the tension slee-
ve and check on free movement.
3. Lubricate the servo saver axle slightly
and press it from the top into the tension
sleeve for servo saver. Secure the servo
saver axle with an M5x10 pan-head
screw. Use screw retention lacquer.
Hint: Fill the bottom part of the receiver box
with some foam to protect the receiver
against vibrations.

3. Switch on the remote control system, set the trimming of
the steering to central position. Adjust the servo saver in
centre to the chassis. First mount one servo rod to the
servo arm of the steering servo using a 2,9x16 pan-head
screw, then mount the second servo rod. Both servo rods
should be adjusted in the same length. You should be able
to mount both servo rods easily and without any resistance
to the servo arm of the steering servo using 2,9x16 pan-
head screws, position 41-43.

All metric screws need to be secured with thread lock fluid.
1. Mount the plastic rc-plate 4WD underneath the front axle stif-
fening to the alloy chassis using 4,2x16 countersunk screws.
2. Now mount the servo saver underneath the plastic rc-plate
4WD by using M5x16 pan-head screw and Ø5,3 disk as pictu-
red. Use screw retention lacquer.
Dirt, but also longer downtimes can
affect the function and free move-
ment of the servo saver. Therefore we
recommend to spray some penetra-
ting oil between tension sleeve and
servo saver part A+B. Then press ser-
vo saver part A downwards against
the spring and check the function. If it
does not function smoothly you have
to dismount and clean the part.
A stiff servo saver can cause a servo
damage.

1. Mount the throttle rods to the carburetor arm using
collets and M3x3 headless pins as described in positi-
on 45. Keep some clearance between the collets and
the carburetor arm. Make sure the carburetor arm can
be easily moved and does not jam.
2. Push the M3x25 pan-head screw from the bottom
into the servo arm as described in position 46 and
secure it with an M3 nut. Screw on two M3 stop nuts
as distance. Switch on the remote control system and
set the trimming for throttle/brake in central position.
Press the servo arm on the the servo as pictured in
position 46 and fix it with enclosed screw.
3. Push the collet, pressure spring, throttle pivot post
and collet on the throttle rods. In doing so, press the
throttle pivot post on the M3x25 pan-head screw and
secure it with an M3 stop nut. Fix the collets using
M3x3 headless pins. See position 46.
Switch on the remote control system. Set the servo for
throttle/brake in central position. Now clamp the collet
to the throttle pivot post using an M3x3 headless pin.
Set the transmitter to full throttle position and check if
the carburetor arm opens completely.
Tipp: Do not tighten the M3 stop nut at the throttle
pivot post. The throttle pivot post and the throttle rods
must run smoothly, move easily and should neither
touch nor clamp in any position.
