No responsibility is taken for the correctness of this information. You have purchased a RTR model, which means it should be ready for immediate use after charging all batteries. You need to check the car, electronics and all plastic parts after each use to make sure no parts are damaged. Also all the moving parts must be checked for their clearance, bolts and screws that they are tight.

Getting Started

NiMh Charging process
Connect the USB charger to a USB port. We recommend a USB adapter (2A) for the grounding receptable. USB ports of computers and laptops usually cannot provide sufficient current to charge the battery. The LED on the charger lights up green. Connect the USB charger to the NiMh drive battery. The red LED of the USB charger signals the charging process. If the plug of the charger and the plug of the drive battery do not match, a charging adapter is included with your model. When the battery is fully charged, the LED lights up green. Make absolutely sure that the charging time is not exceeded. Do not charge any batteries other than the NiMh battery supplied. The average charging time for the empty NiMh battery supplied is approx. 6 – 8 hours. If the LED flashes, there is a fault. Please contact the customer service.
Caution:
Only charge suitable battery‘s with this charger. Suitable battery‘s are Nickel metal hydride battery‘s with max. 6 cells, max. 7,2 V nominal voltage and max. 2000mAh. The battery must have a tamiya plug. The charging of unsuitable battery‘s can cause damage to the charger and the battery‘s. Fire Hazard! The charging connection of the charger is not allowed to get altered or soldered to a different balancer plug type!

LiPo Charging process

Important notes on the suitability of the battery:
Make sure to use only lithium polymer batteries with XH balancer connector. Only these may be used with the charger. Other connections and battery types must not be used (fire hazard due to reverse polarity or overcharging may result).
Please contact the manufacturer of your battery to find out whether your battery is suitable. Only LiPo batteries with a capacity of at least 1600mAh must be used (otherwise there is a risk of fire due to excessive charging current). If you use batteries with a capacity below 1600mAh, the batteries must be approved for a charging current of 1600mA (Speedcharging). Please ask the manufacturer of your battery if your battery meets these requirements.
You may only connect one single battery to the charger at a time. Charging 2 batteries at the same time is NOT allowed and will cause damage to the battery or charger (fire hazard).

Technical data:

1. Power Slot 100 – 240 V
2. 2S Balancer
3. 3S Balancer (Not required for this model)
4. Status LEDs

LiPo Charging process

1. Plug the power cord of the charger into a suitable socket. The LEDS light up green and indicate that the charger is ready for charging.
2. Now connect the empty battery to the charger. 7.4V 2S batteries to the 3 pin connector or 11.1V 3S batteries to the 4 pin connector. Do not use force and pay attention to reverse polarity. The LEDs change to red after a few seconds and indicate that the battery cells are charging.

Attention:
When connecting a 2S battery, only the first 2 LEDs (Cell1-2) change to red, LED 3 (Cell 3) will remain green. When 3S batteries are connected, all LEDs are red (Cell1-3).
As soon as a the battery cell is full, the corresponding LED changes to green. Because the cells are charged individually in a balanced way, it is possible that one cell is fully charged earlier than the others. Always leave the battery on the charger until all connected cells are fully charged (green) to allow the charger to balance your battery

Detecting a full battery.
When you connect a full battery to the charger, the LEDs will turn red for a few seconds and then turn green again. This means that the battery is already fully charged.
Detecting a defective battery.
If the LEDs remain green when an empty battery is connected, there is a defect in the battery (cell defect or deep discharge). In this case, immediately disconnect the battery from the charger and use another battery.
Danger!
Always disconnect the battery from the charger immediately after charging. Always disconnect the charger from the power supply immediately after disconnecting the battery. Inserting the rechargeable battery or charger after charging will result in da-mage to the battery, charger or the power supply (fire hazard).

Inserting batteries into the transmitter
Put 4 AA Batteries into the Transmitter

Battery warning:
Non-rechargeable batteries are not to be recharged!
Do not open!
Do not dispose of in fire!
Do not mix old and new batteries!
Do not mix alkaline batteries, standard (carbon-zinc) or rechargeable batteries!Rechargeable batteries are to be removed from the toy before being charged!Rechargeable batteries are only to be charged under adult supervision!
The supply terminals are not to be short-circuited!

• Put the battery into the battery holder in the vehicle and secure it with the velcro straps. Make sure that the battery is safely locked in the battery holder without any great play.
• Now connect the battery to the speed control in the model. If the plug of the speed control and battery do not match, then you will find a connection lead in your box
• Turn the radio on and make sure all the trim buttons on the transmitter are in neutral position. Read the chapter for usage of the transmitter.
• Keep the car in the air in case that the motor turns at full power.
• Switch the speed control on the On / Off switch.
• We encourage you now to activate your receiver‘s built-in Failsafe unit. On delivery it is turned off. (see chapter Fail Safe).
• If this is your first rc car, we recommend to drive it on a small test track to familiarise yourself with the control of the vehicle and the controls of the transmitter.

Danger.
Always switch off the model immediately after each use. Immediately after each use the battery should be disconnected from the model. The battery can be deeply discharged by leaving it switched on accidentally or leaving it plugged in. Deep discharge causes the battery to lose power or can be damaged to such an extent that charging or discharging is no longer possible or the battery can self-ignite during charging or discharging (fire hazard). Never attempt to charge or discharge deep-discharge batteries. The voltage of the LiPo batteries should never be under 6 volt and the NiMh battery never under 4 Volt to avoid a depth discharge. The fully charged LiPo battery has a voltage of approx. 8,4 Volt and the NiMH battery 8,5 Volt. After usage, the intact battery has to be fully charged after a cooling phase of at least 10 min but not longer than 12 hrs. This is to avoid a deep discharge caused by a self- discharge. When not using or storing the battery´s it has to be checked at least every three months for voltage (For LiPo min. 8 Volt, for NiMh min. 7,4 Volt.) or damage and if necessary charged or disposed.

Attention!
Your vehicle has a pivot front suspension. This has a number of advantages. It is very robust and easy to maintain. The set-up of the car has been done so the drive shaft will not pop out. As with any model, screws and bolts can losen during break-in of the car. This can result in tolerance of the drive shaft. The drive shaft can then pop out if high pressure is applied. The inner ball screw (item No.: 505081) will enable you to adjust the tolerance resul- ting in fine adjustments of the track width. For best results when setting up the pivot ball for the first time, please always adjust the upper and lower pivot in the same way. Fasten as far as the pivot can still be pulled up and down easyly but not as far that it will pop out if you give full steering angle. The outer plastic socket screw (item No.: 505080) is only used for securing of the steering knuckle. This should not be too tight, otherwise the steering is not smooth and the handling can be adversely affected.

Attention!
The front and rear bone pan absorbs most of the motor‘s energy and directs it to the front and rear axles. Therefore, the hexagon socket screws which hold the bone pans on the transmission output shafts must be checked and, if necessary, tightened before the first use and in regular intervals e.g 5-7 uses. Insert a rubber ring to the front and the back connection cup. Please check the tolerance of the drive shaft. The tole-rance should be approx. 1 – 2mm. You may have to move the connection cups to adapt the tolerance. Therefore you need to loosen the grub screws to adapt the connection cup. Afterwards tighten the grub screws. If not, the connection cups will move on the gear output shaft. That might cause the con-nection cup and the middle drive shaft to get damaged.

Trim L/R = steering
Should the wheels rotate forward or backward, even though no command was given through the transmitter, then also the throttle needs to be trimmed on the transmitter.
Trim V/R = forward/backward

Insert the batteries

• Remove the battery compartment cover.
• Fit the 4 x AA batteries, observe the correct polarity.
• Replace the battery hatch

Binding the receiver to the transmitter

As with all modern 2.4GHz R/C systems the receiver must be bound to the transmitter to ensure that the receiver will only eact to signals from that transmitter. If you wish to re-bind the receiver with the transmitter please proceed as follows:

• A. Ensure that the transmitter is fitted with fresh or fully charged batteries and leave the transmitter off.
• B. Plug the binding plug (included) into the channel 3 socket on the receiver.
• C. Switch the receiver system on by connecting the battery or turn in a BEC operating on a controller to control. The receiver LED will begin to flash indicating that the receiver is in bonding mode.
• D. Press and hold down the binding button on the transmitter whilst switching it on.
• E. The transmitter will begin to flash indicating that the receiver is in bonding mode.
• F. Release the binding button on the transmitter and disconnect the receiver from the battery or turn off the controller. Release the binding plug from the receiver.
• G. Switch of the transmitter. And remove the binding wire. The system be bound at the next start .
• H. Install all properly and check anything very precisely.
• I. If the receiver fails to bond or does not function after bonding repeat the above procedure until a successful bonding is achieved.

We encourage you now to activate your receiver‘s built-in Failsafe unit. On delivery it is turned off.
Mount the 2.4 GHz antenna vertically as shown in the diagram. Do not allow any metal object to come into contact with the an-tenna or to shield it as this will reduce the range.

How to setup the fail safe function

1. The instruction of function
   The function of protection of losing control is mainly for r/c boats and cars and keeps them away from damage through throttle channel. When the receiver is out of control signal, the receiver of throttle will automatically return to the initial position which set up before starting to avoid the error action:

2. How to set the function

   • a. Switch on the transmitter power and enter into the working condition
   • b. Connect the receiver with power and enter into the working condition, the signal light on receiver will blink all the time.
   • c. Control the throttle of transmitter and keeps the servo or ESC in the neutral position.
   • d. Press the setting button, the LED will be flash for 3 seconds (see on pict. left).
   • e. Release the setting button. The setting is finished.

3. Testing

   • a. Switch on the transmitter and enter the working condition.
   • b. Contact the receiver with power and enter the working condition.
   • c. Turn off the power of transmitter.
   • d. The throttle of servo will be set automatically.
   • e. Finish these steps above means the setting is ok.

Controller (installed)

Technical Data:

• Operating Voltage: 7,2 – 7,4 V
• Battery Pack: 2 Lipo | 6 NiCd/NiMh Cells
• Internal Resistance: Fwd: 0.002 Ohm, Bwd: 0.004 Ohm
• BEC Voltage: BEC 2A/5V (Linear mode BEC)
• Intended use: RC-Car 1:10
• Protection Circuit: Under voltage cut off
• Continuous load: 40 A
• Size: ~ 45 x 32 x 26 mm

If you want to disable the backward function just set the jumper to disable. If the jumper is set to enable the backward function is enabled.

This regulator has two battery modes which will be set with jumpers. If you are using a Lipo battery this jumper has to be set to Lipo. This function protects the lipo battery against deep discharge and possible damage due to deep discharge! At a threshold voltage of 6 V total the esc switches autom. off to safe the battery from under voltage. If you are using a NiMH battery this jumper has to be set to NiMh. The controller allows a voltage less than 6 V down to 4 V.

WARNING
Your controller is Splash-proof. Not waterproof.
Avoid puddles that are higher than the controller is installed in the vehicle. Do not get the model un-der water. After each ride in the wet, the complete controller must be thoroughly dried and lubricate the mechanical components. Damage caused by improper use overload or lack of maintenance is not covered under warranty.

Using your controller
To operate the ESC, proceed as follows:

• Switch on your transmitter and ensure that the throw for the throttle channel is set to +/- 100%.
• Ensure that the receiver switch is in the OFF position and connect a battery pack ensuring the correct polarity (+ and -).
• Switch the receiver system ON.
• Once a battery is connected the system is ‘live‘ and extreme caution must be exercised to prevent injury due to the motor suddenly starting to turn.
• Do not connect the battery pack until directly before operating the model and disconnect the pack immediate after use.
• Conduct a range test before running the model for the first time. This test should be carried out at full, half and low throttle and if the servos jitter or make uncontrolled movements do not operate the model until the reason for the interference has been established and corrected.
• When the vehicle is being driven forwards, pulling the throttle back past the neutral position will cause the vehicle to brake. To make the vehicle then reverse, the throttle stick must first be moved back to the neutral position for a short period and then the model will reverse.
• If you want to disable the backward function just set the jumper to disable. If the jumper is set to enable the backward function is enabled.

Configuring your controller
The speed controller automatically calibrates itself to the transmitter signal. For this, the trim button of the gas channel at the transmitter must be set to neutral. Turn on the transmitter and then the speed controller. The speed controller signals the calibration with a short melody and is ready for use. In case the speed controller has no clear signal or the trim control is not set to neutral, the speed controller will not initialize.

When using the controller please observe the following safety notes:

• Use only batteries which not exceed the max. operating voltage (2 Lipo cells | 6 NiCd/NiMh cells).
• Allow the ESC to cool down completely before operating it again.
• Remove the battery from the model when not in use.
• Always switch off the receiver first and then the transmitter. On switching on, switch on the transmitter first and then the receiver.
• Only use top quality cables and connectors.
• Make sure that the ESC is adequately cooled and never wrap the unit in anything that insulates.

Before each use make sure to check all bolt connections and cable connections. Your vehicle has a pivot front suspension. This has a number of advantages. It is very robust and easy to maintain. The set-up of the car has been done so the drive shaft will not pop out. As with any model, screws and bolts can losen during break-in of the car. This can result in tolerance of the drive shaft. The drive shaft can then pop out if high pressure is applied. The inner ball screw (item No.: 505081) will enable you to adjust the tolerance resulting in fine adjustments of the track width. For best results when setting up the pivot ball for the first time, please always adjust the upper and lower pivot in the same way. Fasten as far as the pivot can still be pulled up and down easyly but not as far that it will pop out if you give full steering angle. The outer plastic socket screw (item No.: 505080) is only used for securing of the steering knuckle. This should not be too tight, otherwise the steering is not smooth and the handling can be adversely affected.

Setting points 

Suspension Settings

The following settings are possible:
toe-in / toe-out

• A Toe-in: The responsiveness of the steering is less direct and the vehicle tends to oversteer, but it has better directional stability.
• B Toe-out: More direct steering response and understeer, but has a worse directional stability.

Front caster high / low

Less caster: Less caster has a worse directional stability, but provides a better steering on corner entries.
High caster: A higher caster has a better directional stability, but can result in worse corner turn-in.

Setting points 

Negative / positive camber front and rear
You can adjust the front camber by turning one of the inner screws on the pivot front suspension. Turn both screws equally inwards or outwards to adjust the track width.
To adjust the rear camber, turn the rear track rod.

• A Negative camber:
  Better grip on terrain, as the edge of the wheels stem into the ground allowing higher cornering speed. We recommend approx. imately 1.5 degrees negative front and an ave rage of 0 degree to the rear. An excessive negative camber angle can deteriorate the ride quality.

• B Positive camber:
  A Positive camber should be avoided in your vehicle due to poorer ride quality.

Spring tension hard / soft front and rear
To adjust the spring preload, pull the spring down a little and insert the desired clip´s.

• Harder: More direct response of the suspensi-on but reduced grip.
• Softer: Less direct response of the chassis but more grip.

Damper angle soft / firm front and rear
To adjust the damper angle, remove the screw on the suspension arm, adjust the angle and tighten it again.
Soft = More direct steering
Firming = Less direct steering

Safety precausions for battery
Because of the high power compactivity (up to 150Wh/kg) the cells are quite dangerous and need special care! The company Jamara excludes explicitly, all types of liability for damages, that can occure when using the Lithium- Polymer-Cells indequate.

• When using the battery incorrect there is a risk of getting fire or acid-injuries.
• Overcharging, too high power, or discharging at low level destroys the cell.
• Protect from mechanical stress (squeezing, pushing, bending, drilling).
• Never open or cut batteries, do not throw into fire, keep away from children.
• Handle damaged or leaking battery with care. Injuries or damages to the product can occure.
• Under no circumstance short-circuit the device and always watch out for correct polarity.
• Protect batteries from heat above 65 °C , mount away from hot objects (for example exhaust pipe).
• Before storing batteries (for example in the winter) charge the battery. Do not store in fully charged or in non charged state!
• The contents of the cell is harmfull for skin and eye.
• If the content comes into contact with skin, clean with plenty of water and take off moisted clothes.
• If the content comes into contact with the eyes, clean with plenty of water and consult a doctor. If the cell overheats, swells, burns or smoke is coming from it, do not touch it under any circumstances. Keep away in a safe distance and prepare adequate extinguishing agents such (No water explosion, well dry sand, fire extinguishers, fire blanket, salt water).

Disposal restrictions
Batteries and accumulators must not be disposed of in domestic waste. You are obliged to dispose of batteries (seperate collection) appropriately. After use you can return batteries free of charge to the retail store. As batteries contain substances that can be irritant, can cause allergy and are highly reactive, separate collections and proper recycling is important to the environment and to your health. If the batteries are marked with a chemical symbol Hg, Cd or Pb below the crossed-out waste bin on wheels it refers to that more than 0.0005% of mercury (Hg), more than 0.002% of cadmium (Cd) or more than 0.004% Lead (Pb) is included.

Disposal restrictions
Electrical appliances must not be disposed of in domestic waste and must be disposed of separately. You are obliged to take out the batteries, if possible, and to dispose of the electrical equipment at the communal collection points.
