b) Programming the Special Functions
The speed controller is already programmed in the factory with the best pre-settings. No changes should
be made for the first attempts at driving.
The speed controller unit has many different programming options, e.g. adjustment of the braking strength, a low-
voltage protection function for LiPo rechargeable batteries and much more.
We would like to explain the function of the programming using the following example of how to set the handbrake
function.
The higher the set value of the handbrake function, the less the vehicle rolls when it is resting on a slope.
A standard electric motor - at rest - has a certain amount of braking strength due to the magnets it
contains - a brushless electric motor, however, does not.
The basic (factory) setting, for example, is "10%". In the following example, this value is to be changed
to "40%"
For this purpose, proceed as follows:
• Switch off the speed controller (see chapter 9 g, figure 2).
• The remote control transmitter must be activated/must remain switched
on (don't switch it off!). The throttle/brake lever must be in its neutral
position.
• Hold down the small button on the speed controller unit (see arrow in the
picture to the right); then switch the speed controller unit on (do not release
the button, keep it held down!).
Do not use any force when holding the button down. Otherwise
the button may break; you will void your guarantee!
• The red LED on the side of the speed controller unit flashes. Continue to
press and hold the setup button. Don't release it!
• The red LED stops flashing and the green LED begins to flash (continue to press and hold the setup button. Don't
release it!).
Depending on the flash signal given by the green LED, the speed controller unit is in a corresponding
settings menu. At the same time as the flash signal emitted by the green LED, the motor emits a
corresponding beep tone.
The beep tone is generated because the brushless motor is activated for a moment. Depending on the
motor, this beep may be very low or inaudible. In this case, observe the LED on the speed controller.
• Staying with the example of setting the handbrake function - release the set-up button at the exact time when the
green LED flashes twice briefly (2x).
The red speed controller LED flashes to indicate the value currently set for the hand brake function.
