serviced by you. In addition, you will void the warranty if you do!
• The product is not a toy and should be kept out of the reach of children!
• The control unit and the motor may not become damp or wet.
• Always separate the battery from the control until if you do not wish to use the control until. If the control
unit is not used for short periods, it can be deactivated via the On/Off switch.
• Always turn on the transmitter first before connecting the control unit with the battery and switching it on!
• Before turning off the transmitter, turn off the control unit and, if necessary, separate it from the battery.
• The control unit can use NiMH/NiCd rechargeable batteries (5-10 cells) or LiPo rechargeable batteries
(2-3 cells) depending on the programming.
• Both the motor and the control unit can become very hot during operation, danger of burns!
• Handle the product with care; knocks, blows or even a fall from a low height can damage it.
• Do not carelessly leave the packaging material lying around as this may become a dangerous toy for
children.
• Make sure when handling vehicles that parts of your body or other objects are never located within
rotating parts. Risk of injury!
• Only operate the control unit with a rechargeable battery pack, never via a plug-in power supply.
• Only connect one single brushless motor to the control unit.
• The brushless control unit is not suitable for the operation of conventional electric motors with two
connections!
• When installing, keep the largest possible distance between the receiver and the control unit/motor to
avoid mutual interference.
• Don't lay the aerial line of the receiver parallel to the current-carrying cables. Do not coil the antenna cord,
use an antenna tube or similar which sticks vertically out of the vehicle.
• Always switch the transmitter on first and place its motor speed control lever in the neutral setting. The
control unit should only be attached to a rechargeable battery pack once this is carried out.
When switching the vehicle off, follow the reverse order of proceedings, switch off the control unit and
remove it from the rechargeable battery, then switch off the transmitter.
• During operation of the model, sufficient cooling has to be provided for both the control unit and the motor.
Never cover the cooling element of the control unit! Never mount the control unit above the cooling
element (e.g. with an adhesive pad or with velcro).
• The control unit and the motor must not become damp or wet.
• Check the vehicle and the control unit/motor for damages. If you do find evidence of damages, then do
not operate the vehicle or the control unit/motor again.
• Before recharging the rechargeable battery it has to be disconnected from the control unit.
Assembly
• If the product is to be used as a replacement for an existing control unit/motor, then first remove the old
components from your model.
• Mount a pinion gear, suited to the drive gear, onto the driveshaft of the brushless motor. The pinion gear
is generally affixed with a grub screw.
Ensure that the grub screw sits exactly on the flattened side
of the driveshaft and is screwed tight in that position (see
the schematic diagram on the right, without the gear)
otherwise the pinion gear will quickly loosen.
The exact position of the pinion gear on the drive shaft must be determined after the motor
is mounted. Thus, only tighten the pinion gear lightly initially.
• Mount the motor in your vehicle and screw it into place. The distance between the pinion gear and the
drive gear will be set later, it is currently not important.
• Now check that the pinion gear comes into exact contact with the drive gear and is not
skewed to the side.
The exact position of the pinion gear is very important, it must not be
skewed to the side as otherwise the drive gear will be damaged (the
transfer of power will only occur over a small area).
Correct the mounting position of the pinion gear on the drive shaft, where
necessary you may have to remove the motor again.
Only when the pinion gear sits exactly parallel on the driveshaft should the
grub screw be tightened firmly.
• After the correct mounting of the pinion gear on the driveshaft of the motor, the correct distance between
the pinion gear and the drive gear must be set.
• Generally when dealing with motor mounts, one mount hole will be round and the other will be oblong.
The motor is thus attached with the screw in the round hole and can be adjusted with the oblong hole.
Loosen both screws a little, so that the motor can be turned with a small amount of force.
• The distance between the pinion gear and the driveshaft should not be too small and should also not be
too large, as the drive gear will be damaged otherwise.
• Fasten the motor with the screws.
• Now mount the control unit in the vehicle chassis. Choose a location which is as far as possible from the
receiver. The control unit should also not be directly next to the motor.
You can use velcro or double-sided adhesive or similar to attach the unit.
• The on/off button with the integrated setup button is to be attached so that it can be easily operated. This
also requires attachment with velcro or double-sided tape or similar.
• Position all cables so that they cannot become entangled in rotating or moving parts of the vehicle. Use
cable ties to affix them for example.
Connection to the Receiver
• Connect the three motor connections with those of the control unit. The arrangement of connections is
irrelevant. If the rotation direction of the motor is incorrect, simply interchange two of the three
connections.
• Connect the three-pole plug to the corresponding channel of the receiver. Make absolutely sure you have
the correct receiver configuration (see operation instructions for receiver as well as the inscription on the
receiver).

• As the control unit contains a BEC, a receiver battery or rechargeable battery must not be used! The
battery supplies the receiver directly with power via the control unit.
Initial Operation
a) Preparation
Attention, Beware!
Place the model car so the drive wheels do not make contact with the ground or other
objects. Place the vehicle on a hard foam block or similar.
Do not touch the drive mechanism, do not block it. Risk of injury!
• Turn on your transmitter (check the status of the battery or the rechargeable battery!) Place the trim
regulator in the centre position; place the throttle lever in the neutral position.
• The switch on the control unit is to be set to the "OFF" position, see the figure on
the right.
• Insert the rechargeable battery pack in the vehicle and connect it to the control unit.
The control unit has a Mini-Tamiya plug connector. We recommend exchanging this for a
high current capable specialised connector if you wish to use 3 cell LiPo rechargeable
batteries or NiCd-/NiMH rechargeable batteries with more than 6 cells.
If you are in doubt, employ a specialist to carry out the modification!
• Move the throttle and the corresponding trimmer to the neutral position on the remote control. Let go of
the speed pedal, do not move it.
b) Setting the Control Unit on the Receiver
The control unit must be set to the full speed positions for forwards and backwards as well as the neutral
position. For this purpose, proceed as follows:
• Switch off the control unit. Press and hold the small setup button on the left next to the On/Off switch (don't
release it!)
• Set the switch of the control unit to the "ON" position, see the illustration on the right.
• When the red LED on the control unit is lit, release the setup button.
• Move the gas/brake lever to full speed setting and hold it there. The red LED begins
to flash, wait a few seconds until the red LED goes out and the green LED stays
lit, a beep tone is emitted.
If the red LED does not begin to flash when you move the gas/brake lever to full speed (e.g.
pull the lever towards the handle) then switch off the control unit. Activate the reverse setting
for the motor control on the transmitter and begin from the start again.
If the vehicle travels in the wrong direction later on, then interchange two of the motor
connection cable (it is unimportant which cables you interchange).
• Now move the gas/brake lever to full reverse setting and hold it there. The green LED flashes. Wait a few
seconds until both LEDs stay lit and two beep tones are emitted.
• Now release the gas/brake so that it sits in the neutral position. Then wait another few seconds, the red
and green LED flash and then are lit continuously, 3 high beep tones and one lower beep tone can be
heard, the positions are saved, the green or red LED is lit (depending on whether reverse is switched on
or off).
The green LED is lit = reverse activated
The red LED is lit = reverse deactivated
• Switch the control unit off, the programming to the remote control is complete.
If you always use the same remote control, the programming of the settings on the speed
lever for your remote control need only be carried out once and/or when you have made
changes to the setup of your remote control.
Programming the Control Unit
Attention! Before you can operate the control unit and thus the vehicle itself, you must at
least programme the rechargeable battery type!
• Before you begin programming a feature, switch on the transmitter. Leave the gas/brake lever in the
neutral position
• Switch on the control unit.
The green LED is lit = reverse activated
The red LED is lit = reverse deactivated
Switching Reverse On/Off
• Press and hold the setup button; until one LED is lit and the other one flashes. After this occurs release
the setup button.
• You can alternate between the two modes of operation by briefly pressing the setup button:
Red LED is continuously lit, the green LED flashes: Reverse on
Red LED flashes, the green LED is continuously lit: Reverse off.
• Hold down the setup button for at least 2 seconds, this saves the setting and the programme mode is
exited.
• If the setup button is not pressed for some 10 seconds, the programming mode is automatically exited
without saving the changes to the settings.
Setting the Brake
• Press and hold the setup button; until the red LED is lit. After this occurs release the setup button.
• You can alternate between the two modes of operation by briefly pressing the setup button:
Red LED flashes 1x = proportional
Red LED flashes 2x = ABS activated
• Hold down the setup button for at least 2 seconds, this saves the setting and the programme mode is
exited.
• If the setup button is not pressed for some 10 seconds, the programming mode is automatically exited
without saving the changes to the settings.
Setting the Rechargeable Battery Type
The control unit has an inbuilt voltage monitor. If the voltage is too low the control unit is
switched off to protect the batteries.
For NiCd/NiMH rechargeable batteries, the shutdown voltage is 0.8 V, for LiPo rechargeable
batteries 3.0 V per cell.
• Press and hold the setup button; until the green LED comes on. After this occurs release the setup button.
• Briefly pressing the setup button now allows you to switch between:
Green LED flashes 1x = NiCd/NiMH
Green LED flashes 2x = 2 LiPo cells
Green LED flashes 3x = 3 LiPo cells
• Hold down the setup button for at least 2 seconds, this saves the setting and the programme mode is
exited.
OFF
• If the setup button is not pressed for some 10 seconds, the programming mode is automatically exited
without saving the changes to the settings.
Setting the Motor Timing
• Press and hold the setup button; until the red and green LEDs are lit. After this occurs release the setup
button.
• You can now select the motor timing by briefly pressing the setup button:
Red and green LEDs flash 1x = 2°
Red and green LEDs flash 2x = 4°
Red and green LEDs flash 3x = 6°
Red and green LEDs flash 4x = 8°
• Hold down the setup button for at least 2 seconds, this saves the setting and the programme mode is
exited.
• If the setup button is not pressed for some 10 seconds, the programming mode is automatically exited
without saving the changes to the settings.
ON
Resetting the Factory Settings on the Control Unit
• Press and hold the setup button; until the red and green LEDs flash alternately. After this occurs release
the setup button.
• Hold down the setup button for at least 2 seconds, this resets the control unit to the factory settings
(reverse on, rechargeable battery type NiCd/NiMH, Timing 4°, brake proportional).
• If the setup button is not pressed for some 10 seconds, the programming mode is automatically exited
without the control unit being reset to the factory settings.
Beginning Operation:
• Place the vehicle on a suitable surface so that the wheels can turn freely.
• Switch on the transmitter, move the gas/brake lever to the neutral position.
• Switch the control unit off and connect the rechargeable battery pack to the control unit connection.
• Switch the control unit on (move the switch to the "ON" setting) and wait a few seconds until the LEDs
on the control unit are lit.
Red LED on = only forwards gear (reverse is switched off)
Green LED on = both forwards and reverse
• Check the function of the steering servo and control unit/motor.
Set steering trim on the transmitter so that the turned wheels are approximately facing straight ahead.
An exact setting if the steering trim to drive straight ahead can be carried out during driving operation.
Set the trim for the motor to the neutral setting; the motor must not start when the gas / brake
lever on the transmitter is not moved.
If the motor turns in the incorrect direction (e.g. when you accelerate forwards, the wheels
turn backwards) then switch off the control unit and interchange two of the three motor
connection cables (it does matter which of the cables you swap).
• If everything functions correctly, you can now start driving the vehicle, enjoy!
Ending Operation
• First switch off the control unit (bring switch into the "OFF" position).
• Separate the rechargeable battery from the control unit.
• Only now should you turn off the transmitter.
