Damages which occur as a result of disregard for these operating instructions are
not covered by the product guarantee! Liability for any and all consequential damage
is excluded!
Nor do we assume liability for damage to property or personal injury caused by
improper use or the failure to observe the safety instructions! The warranty is voided
in these cases.
• The unauthorized conversion and/or modification of the product is inadmissible because of safety and
approval reasons (CE).
• 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 unclamp 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 (6-12 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 carefully and do not drop it. 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.
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).
Make note of the position, remove the motor and correct the mounting
position of the pinion gear on the driveshaft.
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.
• Then screw down the motor firmly.
• 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.
Ensure above all things that the control unit ventilation cannot be inhibited in its function (danger of
overheating the control unit!)
Connection to the Receiver
• 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 must be set to the "OFF" position, see the figure on
the right.
• Insert the battery pack in the car and connect it to the control unit.
The control unit has a 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. Hold down the small setup button left of the on/off switch
(don't release!) and switch the control unit switch to the "ON" position, see the
figure on the right.
• When the blue LED on the control unit is lit, release the setup button.
• Move the gas/brake lever to full speed setting.
• The red and the yellow LEDs flash and then stay lit, a beep tone can be heard, the full speed setting is
saved.
• Now move the gas/brake lever to full reverse setting.
• The red and the blue LEDs flash and then stay lit, two beep tones can be heard, the full reverse setting
is saved.
• Now release the gas/brake so that it sits in the neutral position.
• The red and the green LEDs flash and then stay lit, three beep tones can be heard, the neutral position
setting is saved, all LEDs cease to be lit.
• Switch the controller 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!
• Switch on the transmitter. Leave the gas/brake in the neutral position
• Switch on the control unit.
The green LED is lit = reverse movement activated
The yellow LED is lit = reverse movement deactivated
Programming Rechargeable Battery Type
The appropriate low voltage protection is activated during the initial programming of the
battery type after the initial commissioning of the control unit. For NiCd/NiMH rechargeable
batteries, the shutdown voltage is 4.0 V, for LiPo rechargeable batteries 6.0 V (2 cells) or
9.0 V (3 cells).
If you should wish to drive without low voltage protection (we do not recommend this!) you
can select driver profile 5. Then you must complete all further programming again.
• Press and hold the setup button; until the red LED comes on. After it is lit release the setup button. The
red LED flashes, you are now in the setting mode for the rechargeable battery type.
• You can select the rechargeable battery type by briefly pressing the setup button. The flash rhythm of the
red LED changes.

Setting the Brake Performance
As with nearly all other control units, the direct movement of the speed / brake lever on the remote control
from forwards to reverse mode activates the brake. However this control unit allows you to adjust the brake
performance to your requirements. Proceed as follows:
• Press and hold the setup button; until the blue and green LEDs come on. After it is lit release the setup
OFF
button. The blue and green LEDs flash (setting mode for brake performance).
• You can select the brake performance by briefly pressing the setup button. The flash rhythm of both LEDs
change.

Activating and Setting the Holding Brake
As opposed to normal electric motors, the driveshaft of the brushless motor can be easily turned. Thus the
model does not stay still on a slope. A type of "holding" brake can be activated for this reason. Proceed as
follows:
ON
• Press and hold the setup button; until the blue and yellow LEDs come on. After they are lit release the
setup button. The blue and yellow LEDs flash (setting mode for holding brake).
• You can activate and deactivate or select the effect of the holding brake by briefly pressing the setup
button. The flash rhythms of the blue and yellow LED change.

without saving the changes to the settings.
Dead Band Setting
The so-called "Dead-Band" setting allows you to adjust the transmission period between forward
propulsion and braking. A low value means that the transmission period is very small, which requires a
particularly finely graded transmitter signal (e.g. as with high quality transmitters). A high value should be
used for simple transmitters.
• Press and hold the setup button; until the blue and red LEDs come on. After they are lit release the setup
button. The blue and red LEDs flash (setting mode for "Dead Band").
• You can change the settings by briefly pressing the setup button. The flash rhythm of both LEDs changes.

Select Driver Profile
The control unit has 5 preprogrammed driver profiles, which differ in their predefined settings. Driver profile
5 also restores the factory settings whereby the low voltage protection is switched off (rechargeable battery
type is retained).
For this reason, driver profile 5 can be used to drive without low voltage protection.
However, we do not recommend such use, as the rechargeable battery can be damaged
in the case of low voltage (e.g. when using LiPo rechargeable batteries <3.0V)!
• Press and hold the setup button; until all four LEDs come on. After they are lit release the setup button.
The four LEDs flash (setting mode for driver profile).
• You can change the setting by briefly pressing the setup button. The flash rhythm of all four LEDs

Brake Function & Reverse Mode
When changing between forwards and reverse (if activated) the speed lever must be put briefly into the
neutral position (ca. 2 seconds).
If the speed lever is shifted directly from forwards to reverse, the control unit's brake will be activated (the
vehicle will NOT go backwards!) The brake performance can be programmed as described above.
Ending Operation
• First switch off the control unit (bring switch into the "OFF" position).
• Separate the rechargeable battery from the control unit.
