IMPORTANT NOTES – GENERAL

• This product is not suitable for children under 16 years of age without the direct supervision of a responsible and knowledgeable adult.

• Carefully read all manufacturers warnings and cautions for any parts used in the construction and use of your model.

• Assemble this kit only in places away from the reach of very small children.

• First-time builders and users should seek advice from people who have building experience in order to assemble the model correctly and to allow the model to reach its performance potential.

• Exercise care when using tools and sharp instruments.

• Take care when building, as some parts may have sharp edges.

• Keep small parts out of reach of small children. Children must not be allowed to put any parts in their mouth, or pull vinyl bag over their head.

• Read and follow instructions supplied with paints and/or cement, if used (not included in kit).

• Immediately after using your model, do NOT touch equipment on the model such as the motor and speed controller, because they generate high temperatures. You may seriously burn yourself seriously touching them.

• Follow the operating instructions for the radio equipment at all times.

• Do not put ﬁngers or any objects inside rotating and moving parts, as this may cause damage or serious injury as your ﬁnger, hair, clothes, etc. may get caught.

• Be sure that your operating frequency is clear before turning on or running your model, and never share the same frequency with somebody else at the same time. Ensure that others are aware of the operating frequency you are using and when you are using it.

• Use a transmitter designed for ground use with RC cars. Make sure that no one else is using the same frequency as yours in your operating area. Using the same frequency at the same time, whether it is driving, ﬂying or sailing, can cause loss of control of the RC model, resulting in a serious accident.

• Always turn on your transmitter before you turn on the receiver in the car. Always turn off the receiver before turning your transmitter off.

IMPORTANT NOTES – NITRO ENGINES

• Always test the brakes and the throttle before starting your engine to avoid losing control of the model.

• Make sure the air ﬁlter is clean and oiled.

• Never run your engine without an air ﬁlter. Your engine can be seriously damaged if dirt and debris get

inside the engine.

• For proper engine break-in, please refer to the manual that came with the engine.

• Keep the wheels of the model off the ground when checking the operation of the radio equipment.

• Disconnect the battery pack before storing your model.

• When learning to operate your model, go to an area that has no obstacles that can damage your model if your model suffers a collision.

• Remove any sand, mud, dirt, grass or water before putting your model away.

• If the model behaves strangely, immediately stop the model, check and clear the problem.

• To prevent any serious personal injury and/or damage to property, be responsible when operating all remote controlled models.

• The model car is not intended for use on public places and roads or areas where its operation can conﬂict with or disrupt pedestrian or vehicular trafﬁc.

• Because the model car is controlled by radio, it is subject to radio interference from many sources that are beyond your control. Since radio interference can cause momentary loss of control, always allow a safety margin in all directions around the model in order to prevent collisions.

• Do not use your model:

- Near real cars, animals, or people that are unaware that an RC car is being driven.

- In places where children and people gather

- In residential districts and parks

- In limited indoor spaces

- In wet conditions

- In the street

- In areas where loud noises can disturb others, such as hospitals and residential areas.

- At night or anytime your line of sight to the model may be obstructed or impaired in any way.

To prevent any serious personal injury and/or damage to property, please be responsible when operating all remote controlled models.

• Do not run near open ﬂames or smoke while running your model or while handling fuel.

• Some parts will be hot after operation. Do not touch the exhaust or the engine until they have cooled.

These parts may reach 275°F during operation!

IMPORTANT NOTES – ELECTRICAL

• Insulate any exposed electrical wiring (using heat shrink tubing or electrical tape) to prevent dangerous short circuits. Take maximum care in wiring, connecting and insulating cables. Make sure cables are always connected securely. Check connectors for if they become loose. And if so, reconnect them securely. Never use R/C models with damaged wires. A damaged wire is extremely dangerous, and can cause short-circuits resulting in ﬁre. Please have wires repaired at your local hobby shop.

• Low battery power will result in loss of control. Loss of control can occur due to a weak battery in either the transmitter or the receiver. Weak running battery may also result in an out of control car if your car‘s receiver power is supplied by the running battery. Stop operation immediately if the car starts to slow down.

• When not using RC model, always disconnect and remove battery.

• Do not disassemble battery or cut battery cables. If the running battery short-circuits, approximately 300W of electricity can be discharged, leading to ﬁre or burns. Never disassemble battery or cut battery cables.

• Use a recommended charger for the receiver and transmitter batteries and follow the instructions

correctly. Over-charging, incorrect charging, or using inferior chargers can cause the batteries to become dangerously hot. Recharge battery when necessary. Continual recharging may damage battery and, in the worst case, could build up heat leading to ﬁre. If battery becomes extremely hot during recharging, please ask your local hobby shop for check and/or repair and/or replacement.

• Regularly check the charger for potential hazards such as damage to the cable, plug, casing or other defects. Ensure that any damage is rectiﬁed before using the charger again. Modifying the charger may cause short-circuit or overcharging leading to a serious accident. Therefore do not modify the charger.

• Always unplug charger when recharging is ﬁnished.

• Do not recharge battery while battery is still warm. After use, battery retains heat. Wait until it cools down before charging.

• Do not allow any metal part to short circuit the receiver batteries or other electrical/electronic device on the model.

• Immediately stop running if your RC model gets wet as may cause short circuit.

• Please dispose of batteries responsibly. Never put batteries into ﬁre.

IMPORTANT NOTES – NITRO FUEL

• Handle fuel only outdoors. Never handle nitro fuel indoors, or mix nitro fuel in a place where ventilation is bad.

• Only use nitro fuel for R/C models. Do not use gasoline or kerosene in R/C models as it may cause a ﬁre or explosion, and ruin your engine.

• Nitro fuel is highly inﬂammable, explosive, and poisonous. Never use fuel indoors or in places with open ﬁres and sources of heat.

• Always keep the fuel container cap tightly shut.

• Always read the warning label on the fuel container for safety information.

• Nitro-powered model engines emit poisonous vapors and gasses. These vapors irritate eyes and can be highly dangerous to your health. We recommend wearing rubber or vinyl gloves to avoid direct contact with nitro fuel.

• Nitro fuel for RC model cars is made of the combination of the methyl alcohol, castor or synthetic oil,

R/C & BUILDING TIPS

• Make sure all fasteners are properly tightened. Check them periodically.

• Make sure that chassis screws do not protrude from the chassis.

•

For the best performance, it is very important that great care is taken to ensure the free movement of all parts.

• Clean all ball-bearings so they move very easily and freely.

• Tap or pre-thread the plastic parts when threading screws.

• Self-tapping screws cut threads into the parts when being tightened. Do not use excessive force when tightening the self-tapping screws because you may strip out the thread in the plastic. We recommended

REAR SUSPENSION MULTI-FLEX™TECHNOLOGY

The all-new rear suspension design features Multi-Flex™ quick adjustment to easily adapt the handling of the

car to particular track conditions and tires used. There are 3 different flex characteristics to choose from.

ALTERNATIVE 1

SOFT

Graphite brace and posts are not used. This allows maximum flex of the rear suspension and generates maximum rear traction. Recommended for low-traction tracks.

ALTERNATIVE 2

MEDIUM

Graphite brace connected to 2-speed bulkheads without posts. This slightly reduces the flex of the rear suspension and improves out-of-corner steering and rotation of the car, but also slightly decreases rear traction. Recommended for medium-traction tracks.

ALTERNATIVE 3

STIFF

(INITIAL SETTING)

Graphite brace connected to 2-speed bulkheads with posts. This connects the entire rear suspension together, creating a stiff frame which allows the car to rotate more and improves out-of-corner steering. Recommended for high-traction tracks.

is recommended for smaller, technical tracks when fast direction changes and side weight changes are needed. Follow the “Alternative 2“ assembly steps starting on page 28; DO NOT assemble the blade bars as described immediately below.

DETAIL

When the bar is set, verify that both sides move at the same time. If they do, the bars are set up correctly. If not, make sure that both downstops are the same. If the arms still do not move at the same time, gently loosen the screw which holds eccentric bushing and adjust the bushing until both arms move at the same time.

FORWARD ARM POSITION Shim behind arm

HUDY GRAPHITE GREASE #106210

It is extremely important that the arms move freely on the pivot pins. If they do not, use the #107634 HUDY Arm Reamer to slightly resize the holes in the arms.

ARM REAMER

IMPORTANT!

The position of the front arm directly inﬂuences the steering Ackermann (angle of the steering linkages). When the arm is moved to rearward position (shim in front of the arm), the angle of the steering linkages changes and gives less Ackermann. By decreasing the Ackermann, the car gets more turn-in & increased steering at corner exit, but less cornering speed. The Ackermann can be changed by the Quick-Saver™ (see page 33).

Ensure that the suspension arms move freely

. Ensure that the eccentric holders move freely.

DETAIL

Each anti-roll bar blade has a hex hole at its end. Use a 1.5mm hex wrench to adjust the blades.

Do not insert ball into cup too deeply

INITIAL PRELOAD

STEP 1 gives the most Ackermann and makes the car understeer more into & out of corners. It offers good cornering speed and creates very good traction mainly in chicanes, because the car will be more stable. Recommended for tracks with long sweepers where a lot of cornering speed is needed.

STEP 4 gives the least Ackermann and creates a lot of steering into & out of corners. However, the car is more difficult to drive in chicanes because there is less traction and stability. Recommended for tracks where a lot of in-corner steering is needed.

The fuel tank has a larger fuel volume and includes OPTIONAL tank inserts for decreasing the volume of the tank. Using the inserts allows you to adjust the volume of fuel inside the tank; this works in conjunction with variables such as fuel ﬁlter capacity and/or length of fuel line to ensure you have the legal fuel volume limit for racing.

Tube holders are easily connected to the fuel tank by screws. Using screws is much more secure than using glue to attach the holders to the fuel tank.

2CC FUEL TANK INSERT

The larger insert decreases the fuel tank volume by 2cc, and is recommended for use when the fuel ﬁlter is used.

TECH TIP FOR EXTRA BOTTOM-END POWER

For extra bottom-end power, thread a M3x4 set-screw (#901304) into each clutch ﬂyweight as shown. The set-screw will add more weight to the end of the ﬂyweight which will cause the ﬂyweight to open harder, giving more bottom-end power. This is recommended for high-traction tracks where bottom-end power is required.

IMPORTANT!

Install set-screw into free (non-pivot) end of ﬂyweight.

After inserting the set-screw, some excess material may come out of the hole. REMOVE this excess material with a knife.

TECH TIP FOR RX8 CLUTCH SHOE

To ensure that the RX8 clutch shoe works properly and for a long time, it is very important to run in the clutch shoe.

Please follow these run-in steps to help ensure proper clutch operation:

Install clutch according to manual.

➊

Check that the spring preload is not too much; for run-in process use less preload.

➋

When you start the engine, the clutch should start engage under low RPM.

➌

If the clutch engages only under high RPM, stop the engine and loosen the spring preload collar. Repeat until the clutch engages under low RPM.

Run in the clutch shoe on the track, or on the starter box if you have only limited time.

➍

(We recommend running it in on the track.)

DETAIL

#901304 NOT INCLUDED

M3x4

CUTAWAY VIEW

Run in the clutch shoe for 1 tank of fuel using a soft preload setting, and then after that

➎

slightly tighten the spring preload. DO NOT run in the clutch shoe under high RPM.

Continue this process until the clutch shoe is properly run in; this will be indicated by a dark

➏

and glossy surface colour on the top of the clutch shoe.

➌

Install the clutchbell, outer ball-bearing (small), and thrustbearing assembly on the engine crankshaft. DO NOT install the inner ball-bearing or internal shims.

Push the clutchbell onto the clutch shoe and measure distance A as indicated.

Pull the clutchbell away from the clutch shoe and measure distance B as indicated.

The clutch gap is A - B; the correct gap is 0.6-0.7mm

If the clutch gap is greater than this, you can easily calculate the thickness of shims required to set correct gap: Thickness of shims required (in mm) = A-B-0.7

For example, using the values A=5.5mm, B=4.5mm Shim thickness = 5.5-4.5-0.7=0.3mm

Place shims on the small collar, outside the thrustbearing assembly.

Be careful not to cross-thread the collar on the shock body.

DO NOT USE CROSSED-OUT PARTS

SHOCK FILLING

Fully extend the piston rod so the piston is at the

➊

bottom of the shock body.

➋

Hold the shock upright and slightly overﬁll the shock body with shock oil.

➌

Let the oil settle and allow air bubbles to rise to the top. Slowly move the piston up and down until no more air bubbles appear. Add shock oil as necessary.

➍

Pull the piston rod most of the way out of the shock body. Let the shock rest for 5 minutes to allow the air bubbles to escape.

CUTAWAY VIEW

After you insert the membrane ensure that it sits properly all around the alu cup properly.

When installing the shock cap assembly on the shock body, some oil will leak out... this is normal.

Fully tighten the cap and clean off any excess oil.

After the shock is assembled, the shock rod will push itself out of the shock body fairly quickly.

Follow the next procedure to adjust the rebound.

REBOUND ADJUSTMENT

AFTER THE SHOCK IS ASSEMBLED YOU HAVE TO SET THE SHOCK REBOUND.

➊

Release the shock cap by 2-3 turns.

➋

Push the shock shaft fully up. For the first time the extra oil will release through the hole in the alu cap-nut.

➌

Tighten the shock cup. When tightening the shock cap, extra oil will again release through the hole in the alu

cap - nut. When tightening, the shock shaft will push out from the shock body.

REBOUND CHECK

It is very important to push the shock shaft into the shock body slowly otherwise air can come into the shock body which would create bubles.

100% rebound - repeat step 2 and 3 two - three times 75% rebound - repeat step 2 and 3 until the shock shaft will push out 75% of its length 50% rebound - repeat step 2 and 3 until the shock shaft will push out 50% of its length 25% rebound - repeat step 2 and 3 until the shock shaft will push out 25% of its length 0% rebound - repeat step 2 and 3 until the shock shaft will push out 0% of its length

If the shock shaft does not rebound enough, you will have to refill the shock with shock oil, and then repeat the bleeding and rebound adjustment procedure.

SHOCK LENGTH ADJUSTMENT

It is VERY important that all shocks are equal length. Fully extend the shock absorber and measure the end-to-end length; we recommend using digital calipers to give an accurate measurement. If a shock absorber is shorter or longer than others, adjust the shock length by tightening or loosening the ball joint on the shock rod.

CARB LINKAGE ADJUSTMENT

NEUTRAL (IDLE)

Approx. 0.5mm

Turn on transmitter and receiver and set the throttle servo trim to the neutral position.

Adjust the idle adjustment screw on the carburetor to open approx. 0.5-1mm.

Adjust both collars on the carb and brake linkages accordingly. The carb linkage must have approximately

0.5mm of preload on the spring at neutral.

DO NOT ADJUST while the engine is running.

FULL THROTTLE

IDLE ADJUSTMENT SCREW Do not allow carburettor to close to less than 0.5mm.

Approx. 0.5-1mm

Engine idling

With the engine NOT RUNNING but the receiver turned ON, apply full throttle at the transmitter.

Adjust the transmitter‘s throttle servo high-end point so that the servo horn fully opens the carburettor when the transmitter‘s throttle control (e.g., throttle trigger) is at 95% of full throttle. The servo should not have excessive strain when at full throttle, or throttle/carb damage will result.

If the transmitter does not have throttle high-end point adjustment, adjust the throttle linkage pivot position on the servo horn until full throttle is obtained.

BRAKE

Adjust the composite collar on the brake linkage so the brakes work smoothly.

If the brakes apply too much or not enough, adjust the collar accordingly. If your transmitter has throttle servo lowend point adjustment (or brake adjustment), use that to set the appropriate amount of throttle servo horn throw.
