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

LiPo Charging

• Plug the charger into the mains socket. The green LED indicates ready to charge.
• Connect the battery to the charger. The LED lights up red during the charging process.
• When the charging process is complete, the LED changes to green again.
• The average charging time of the empty battery is about 5-7 hours (LiPo)
• Put 4 AA Batteries into the Transmitter

WARNING:

If the LED starts to flash when you connect the battery, disconnect the Battery immediately from the charger. A fl ashing LED signals a defective battery.
Defective batteries must not be charged, there is an increased risk of fire!

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

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 damage to the battery, charger or the power supply (fire hazard).!

• Put the battery into the battery holder in the vehicle. Make sure that the battery holder is scured properly with the 2 included clips for the battery holder.
• 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.

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.

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

Binding the receiver to the transmitter

The receiver must be bound to the transmitter to ensure that the receiver will only react to signals from that transmitter.

If you wish to re-bind the receiver with the transmitter please pro- ceed as follows:

1. Put the battery into the

Now connect the battery to the speed control in the model.

2. Plug the binding plug (included) into the channel 3 socket on the

3. Switch the receiver system on. Depending on your soft- ware version of your receiver indicates the different bin- ding mode (instead of flashing lights for example LED or remains out completely). The binding process as such is in all versions. The receiver LED will begin to flash indicating that the receiver is in bonding

4. Press and hold down the binding button on the transmitter whilst switching it

5. The transmitter will begin to flash indicating that the receiver is in bonding mode.

6. Release the binding button on the transmitter and turn off the controller. Release the binding plug from the receiver.

7. Switch of the transmitter. And remove the binding wire. The system be bound at the next start .

8. If the receiver fails to bond or does not function after bond- ing repeat the above procedure until a successful bonding is

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 antenna 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 :

Using Your ESC

Connecting the Receiver, Battery Pack and Motor
Connect the ESC, motor, receiver, battery and servo according to the diagram.
Ensure that you observe the correct polarity of the battery pack. The red cable should be connected to the ‘+‘ Plus Pole and the black cable to the ‘-‘ Minus Pole. The ’#A’, ’#B’ and ’#C’ plugs are connected to the motor. The ‘SET‘ button initiate the pro- gramming mode.

The ESC should be plugged into the throttle channel of your re- ceiver which is normally channel 2. If in doubt, check your Radio- Control System’s instructions. The 3 Motor wires (#A’, ’#B’ und ’#C’) can now be connected, these connectors can be plugged in any order, and if the motor rotates in the wrong direction any 2 of the wires should be swapped.

Note:

You can use the servo reverse function of your transmitter to reverse the motor direction but the ESC will have to be re-ca- librated afterwards

Throttle range calibration

To ensure that your ESC operates correctly it has to be calibrated. During this process the full throttle, stop and brake positions will be set. There are 3 occasions when the unit must be calibrated.

• Before using the ESC for the first time
• If you change to a new transmitter
• If the neutral point or servo throw is changed within your transmitter

To calibrate the system, please proceed as follows:

1. Ensure that the receiver is switched OFF and switch ON the transmitter. If you are using a Futaba The throw should be set to neutral. If the transmitter is fitted with an ABS function this must be de-activated.
2. Press and hold down the ‘SET‘ button on the ESC and switch the receiver switch ON. This will switch the ESC into Calibration’ mode and the LED will begin to blink. If you fail to release the ‘SET’ button as soon as the LED blinks, the ESC will enter ‘Programming’ mode. If this happens, you will have to switch the ESC off and start again to enter ‘Calibration’
3. Parameters can be set here:
   • Neutral point
   • Full throttle forwards
   • Full throttle reverse

The procedure for setting these 3 points is outlined below:

4. Ensure that the throttle control is in the neutral position and press the ‘Set‘ button. The green LED will flash once and the motor will omit a beep. Move the throttle control to the full throttle (forwards) position and press the green ‘Set‘ button. The green LED will flash twice and the motor will omit 2 Move the throttle control to the full reverse position and press the ‘Set‘ button. The green LED will flash 3 times and the motor will omit 3 bleeps. 3 Seconds after this procedure has been followed, the motor is ready for use.
   

LED’s, errors and protection

In normal use the LED will illuminate as follows:

1. If the throttle control is in the neutral position, neither the red or green LED will
2. The red LED will illuminate if the vehicle is driving forwards or in reverse. If the vehicle is braking, the red LED will flash rapidly. When the car moves forward, the red LED solidly lights; the green LED also lights up when the throttle stick is at the top position (100% throttle).
3. The green LED will illuminate when the vehicle is at full throttle either forwards or in

In certain circumstances the ESC will omit an acoustic tone to warn you of a problem:

1. On switching on, the ESC will check the battery pack voltage and if it falls outside the correct values it will omit double signals followed by a 1 second pause: “beep-beep-, beep-beep-, beep-beep-”
2. If the ESC does not receive a signal from the transmitter it will omit single signal followed by

a 2 second pause: “beep-, beep-, beep-”

The ESC has ben equipped with a series of protective circuits to ensure safe operation:

1.     Low voltage cut-o ff:

If the voltage drops below the set value for more than 2 seconds the ESC will switch the motor off. Please note that the motor cannot be started again if the voltage is below the choosen value per cell.

2. Temperature cut-off

If the internal temperature of the ESC rises above 95°C for more than 5 seconds the motor

will switch off. After the ESC switches off it has to cool down before operating again.

Otherwise the ESC will be damaged. This function should not be disabled!

3. Signal loss

If the signal is lost for more than 0.2 seconds the ESC will switch the motor off.

This ESC is fitted with many useful functions and to help you to be able to make the most of the various options they are explained below. Please use the programming table shown on page 6 together with these explanations to program your ESC quickly and effectively:

1. Drive mode :

If option 1 is selected in Drive mode, the vehicle will only drive forwards and the brake is active which make this mode the best choice for racing. In mode 2 the vehicle can be driven forwards or in reverse and the brake is also active. This mode is useful for general use and training.

Note:

When option 2 is selected, moving the throttle control back past the neutral point will initially activate the brake. If the throttle control is then moved back to the neutral position briefly the ESC will switch over to reverse. Moving the ESC forwards will make the vehicle drive forwards regardless of whether it was braking or moving in reverse.

2. Drag Brake force:

In this option the drag braking force can be set. The value is set as a percentage and the values are from 0 to 40%

3. Low voltage :

In this option you can set the low voltage cut-off value. The cut-off voltage can be set between

3.4 and 2.6 Volts per cell. Once the cut-off voltage has been reached the motor will stop.

4. Start Mode :

With this option you can choose how the vehicle will accele rate when full throttle is applied and you can set the value between ‘Soft‘ and ‘Very Aggressive‘. Please note that if you select one of the 2 ‘Aggressive’ modes that you will need to have batteries with a very low internal resistance otherwise the voltage will drop due to the high current draw and the motor may stutter. Also ensure that your motor and gearing are capable of carrying the high loads.

5. Brake :

The ESC is equipped with a braking system which works proportionally to the throttle control. This means that the further the throttle control is moved rearwards the more braking force will be applied. A higher value here will mean that the vehicle will brake harder but more strain will be placed on the components, for example, the gearing.
To avoid the programming procedere with the set up botton, you can all so use the seperatly available Programmcard ( Ord.No. 08 1454 ).

Menu structure

Important note:

In addition to the red LED blinking, the motor will omit an acoustic signal. After every change to the values the ESC must be switched off to store the values. The new settings will not be effective until the ESC is re-started.

– Connecting the programming card

To connect the programming card to the speed controller, disconnect the fan cable (1) from the connector between the motor cables. Connect the cable to the programming card, making sure that the cable is connected correctly (see connection diagram, Fig. 2). Be sure to reinsert the fan cable after completing the programming.

Suspension Settings

The following settings are possible:

toe-in / toe-ou t

• Toe-in: The responsiveness of the steering is less direct and the vehicle tends to oversteer, but it has better directional
• Toe-out: More direct steering response and

understeer, but has a worse directional stability.

– Negative camber / positive camber front and rea r

• 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.

• Positive camber:

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

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.

– Spring tension hard / soft front and rea r

Harder: More direct response of the suspension but reduced grip.
Softer:Less direct response of the chas- sis but more grip.
Damper angle soft / firm front and rea r Soft: More direct steering
Firming: Less direct steering
Spring defelxion more / less front and rear
Less: Less ground clearance and lower center of gravity
More: More ground clearance and higher center of gravity

– Spare Parts

Please note!

If your wheelybar is not mounted all ready, you have to assemble it.
First remove the rear bumper. To do this remove the marked screws as seen on picture 1+2.
Now you can take the rear bumper with it´s brace by side.
Now take the crews that come with the wheelybar and mount it on the rear side of the gear box housing picture 3 and with the earlier disassembled screws picture 1 on the lower side of the chassis.
You can leave the lexan body like it is. But we recommend to cut it out for the wheely bar. Just cut out the marked section, picture 5
