Connection
Connection Diagram:
• Connect two motors with the drive control. The four motor cables are marked so you will know
which ones to use for motor 1 and which ones for motor 2. If the rotation direction of a motor
is not correct anymore later on, switch the two cables of the motor (e.g. exchange the two
cables for motor 1 with each other) and set the servo reverse correctly on the remote control.
However, do not switch the cables leading to the rechargeable batteries. This
destroys the drive control and the warranty/guarantee will be void!
• Connect the three-pole plug on your receiver. Make absolutely sure you have the correct
receiver configuration (see operation instructions for receiver as well as the inscription on the
receiver).

Ground
• As the drive control does not have a BEC, you may not use a receiver battery or rechargeable
receiver battery! The rechargeable batteries supply the receiver directly with power via the
drive control.
• Install the On/Off switch of the drive control in the car; place the switch to the “OFF” position.
Running the vehicle
• Turn on you transmitter (control 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 of the drive control must be set to the "OFF" position.
• Insert two rechargeable batteries of the same type (same manufacturer, same design, same
capacity, same charge level) into the vehicle and connect them with the drive control.
Attention!
Place the model car so the drive wheels do not make contact with the ground or
other objects. Do not touch the drive mechanism, do not block it. Risk of injury!
• Let go of the throttle or move it to the neutral position. Put the trimmer for the throttle/brake
into the center position. Do not move the throttle anymore.
• Turn the drive control on (switch into the "ON" position).
• The motor emits a brief confirmation beep and the LED1 in the drive control blinks rapidly
alternating between red and green (approx. 2 seconds). Then the motor emits a confirmation
beep ("DO-RE-MI"), the neutral position is saved and the LED1 in the drive control is
permanently lit (green).
• The drive control is now ready for operation, you can steer the vehicle via your remote
control.
Please note:
When changing between forward and reverse drive, the throttle must be briefly
placed in the neutral position (ca. 2 seconds).
If the throttle is shifted directly from forwards to reverse without a break in between,
the drive control's brake will be activated (the vehicle will NOT drive backwards!)
If the vehicle reacts exactly opposite, exchange the two cables of motor 1 with each other
(or the two cables of motor 2) and set the servo reverse correctly on the remote control.
• The LED1 lights green in neutral position, blinks fast when driving forward (red) or slow when
driving in reverse (red). If LED1 stays permanently red (depending on the transmitter, this
visual display may not appear), you have reached the end position (full throttle).
If the transmitter signal fails, the drive control turns off the motors for safety reasons
(however, the steering servo will shake if you do not have a failsafe installed).
If the drive control overheats, the engines are shut off as well and LED2 lights up.
In this case, check e.g. the transmission of the drive or the motor type.

Safety instructions
The guarantee/warranty will be void if damage is incurred resulting from non-
compliance with the operating instructions. Liability for any and all
consequential damage is excluded!
We do not assume any liability for damage to property or personal injury
caused by improper use or the failure to observe the safety instructions! In
such cases the guarantee is voided.
• The unauthorized conversion and/or modification of the product is inadmissible because of
safety and approval reasons (CE). Never cut the cable/plug off the drive control, this will
cause the warranty to be void.
• The product is not a toy and has no place in the hands of children.
• The product should not be allowed to become damp or wet.
• Do not short-out the connecting cable, as this would damage the drive control. The same is
true for overload (e.g. through the use of an inappropriate motor) or by incorrect polarity.
Never attach a Schottky diode. Only use electric motors with radio interference shielding.
• Unclamp the battery from the control cruise if you do not use the latter. If the cruise control
is not used for brief period, it can be deactivated via the the On/Off switch.
• Always turn on the transmitter first before connecting the control cruise with the battery and
switching it on!
• Before turning off the transmitter, turn off the cruise control and, if necessary, separate it from
the battery.
• The drive control is designed exclusively for NiMH/NiCd rechargeable batteries with 6 cells.
• The cooling system can become very hot during operation, danger of burning!
• Handle the product carefully, it can be damaged by impacts, strikes or by falling from a low
height.
• Do not leave packaging material unattended. It may become a dangerous toy for children!
Installation
Install the control cruise with double-sided scotch tape (or with a Velcro), as far from the
receiver as possible. You can also attach the drive control with screws. The corresponding
holes are located on the side of the drive control.
The power cable to the motors and to the rechargeable batteries as well as the thin control
cables must be installed far from the aerial cable (the aerial cable should run directly from the
receiver to the aerial fitting). Otherwise this can lead to malfunction of the model or a shorter
radio range.
Make sure that the cruise control is sufficiently cooled. The cooling fins must not be covered.
You can also install a fan on the cooler. Please refer to the chapter "Installing a fan".
The cables must not get into moving parts, secure them with cable fasteners.
