• Function #12, red LED flashes twice long and twice briefly: Start mode
The vehicle will start to move with more or less force depending on the setting. For a crawler, a low setting
should be selected to allow a smooth start of the vehicle.
• Function #13, red LED flashes twice long and thrice briefly: PWM frequency (clock frequency)
A higher setting allows more sensitive control of the speed controller; however, the speed controller warms
up more due to the higher PWM frequency.
• Function #14, red LED flashes twice long and four times briefly: BEC voltage
Here you can set the BEC voltage (output voltage of the speed controller for the power supply of the
receiver and steering servo).
For safety reasons, always use the 6 V setting if you are unsure whether the receiver and steer-
ing servo allow the higher setting. Setting the voltage too high may damage the receiver or the
steering servo and thus result in a loss of warranty/guarantee!
• Function #15, red LED flashes thrice long: Free wheel
For crawler vehicles, this function should be turned on to enable a linear driving behaviour at low speeds.
Adjusting the neutral and full throttle setting
If the vehicle does not stay stationary when the throttle/brake lever is in the neutral position, you can adjust
the throttle trim on the remote control. If the trim is insufficient (or if the trim is almost in the end position),
you can reset the trim accordingly.
Proceed as follows:
• Switch on the transmitter, leave the throttle/brake lever in the neutral position. Set the trim for the drive
function to the neutral position.
• Turn off the speed controller by pressing and holding down the on/off button for more than 0.5 seconds.
• Keep the setup button pressed and turn on the speed controller by briefly pressing the on/off button.
• The red LED on the speed controller will then flash and the motor will emit beeps. Release the setup
button.
Beeps are generated by a brief activation of the motor.
• Release the throttle/brake lever on the remote control so that it is in the neutral position.
• If you press the setup button briefly, the red LED on the speed controller will flash once briefly and you will
then hear a beep. The neutral position has been saved.
• Move the throttle/brake lever on the transmitter to the full speed throttle position, then pull it as far as it will
go in the direction of the handle and hold it there.
Attention!
If you do not move the throttle/brake lever on the transmitter or do not move it far enough during
programming, the vehicle may respond to even minute movements of the throttle/brake lever
on the transmitter or become uncontrollable upon completion of programming. In this case,
reprogram it.
• If you press the setup button briefly, the red LED on the speed controller will flash twice briefly and you will
then hear two beeps. The full forwards throttle position will be saved.
• Move the throttle/brake lever to full reverse throttle (push the lever away from the handle as far as it will
go).
• If you press the setup button briefly, the red LED on the speed controller will briefly flash three times and
you will hear three beeps. The full reverse throttle position will be saved.
• Release the throttle/brake lever to return it to the neutral position. Wait for at least three seconds. The
speed controller will exit settings mode and apply the new settings.
Resetting the speed controller
You can reset the speed controller either via the programming card or the control buttons of the speed
controller.
When resetting via the programming card, refer to section “Programming via the supplied programming
card”.
If you want to reset the speed controller using its control buttons, proceed as follows:
• Switch on the remote control. Leave the throttle/brake lever in the neutral position, do not move it.
• Turn on the speed controller (briefly press the on/off button). Wait until the speed controller has completed
a self-test and the LED stops flashing/goes off.
The speed controller must not be in programming mode.
• Now press and hold down the setup button for more than three seconds.
• The red LED on the speed controller lights up once long and a long sound signal is emitted (the sound
signal is generated by activation of the motor). Finally, the red LED flashes.
• Now turn off the speed controller by pressing and holding down the on/off button (for more than 0.5
seconds).
• With the speed controller turned on, all settings are thus reset to their default values. You now have to
programme the neutral and full throttle settings as well as make all other settings.
Getting Started with the Speed Controller
Attention, be careful!
Place the model vehicle 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!
• Switch on the transmitter and then check the rechargeable battery or battery status of the transmitter.
Release the transmitter controls, do not move them.
• Insert a drive battery into your vehicle and connect it to the speed controller.
Attention!
You should pay attention to the correct polarity of the trip controller's connection cable: Red =
Plus (+) and Black = Minus (-). If incorrectly connected, the speed controller and the recharge-
able drive battery can be destroyed! Danger of explosion/burns!
• To turn on the speed controller, briefly press the on/off button.
• A red LED on the speed controller is used to display the function. Sound signals that are generated by a
short activation of the drive motor also serve for further signalling.
Meaning of the sound/LED signals
Function
One short beep, LED flashes once briefly
NiMH vehicle battery detected
Two short beeps, LED flashes twice briefly
2-cell LiPo battery detected
One long beep, LED lights up once long,
LED goes off
The speed controller has received a valid signal from the
transmitter, the throttle/brake lever is in the neutral posi-
tion, the speed controller is ready for use
LED flashes continuously
The transmitter is switched off or the throttle/brake lever
is not in the neutral position
• Now check the drive and steering functions of the vehicle; observe the operating instructions for your
remote control system.
Ending operation
• Move the throttle/brake lever on the transmitter to the neutral position so that the vehicle is stationary (if
necessary, adjust the trim controller on the transmitter so that the motor stands idle).
• Switch off the speed controller.
• Disconnect the drive battery from the speed controller completely.
• Only now do you switch the transmitter off.
Excess temperature protection
If the speed controller becomes too hot, the motor will turn off. In this case, the red LED emits flashing
signals. When the speed controller cools down sufficiently, it is ready for operation again.
Fail-safe function
The speed controller switches off the motor for safety reasons, if there comes no valid signal from the re-
ceiver. In this case, the red LED flashes. If your transmitter/receiver has its own fail-safe function, programme
it correctly! Check this function so that it works correctly in the event of failure.
