Description of the setting functions:
• Function #1, green LED flashes 1x short: Drive function
In this settings menu the speed controller unit can be switched between the driving functions „Forwards/brake“ and
„Forwards/brake/reverse“. The setting „Forward/brake“ can deactivate reverse driving; this is frequently required in
competitions.
• Function #2, green LED flashes 2x short: Motor brake
If you reduce the throttle at the transmitter or move back the throttle/brake lever into the neutral position, the vehicle
will slow down automatically. The effect is thus exactly like that of the motor-braking function in a „real“ car when you
release the throttle pedal without stepping on the brake pedal.
This also corresponds to the brake function of a conventional electric motor (a brushless electrical motor does not
have any strong magnets that brake the rotor).
• Function #3, green LED flashes 3x short: Undervoltage protection
If LiPo rechargeable batteries are used, then you must ensure that the low-voltage protection is activated and set
correctly (we recommend at least 3.0 V per cell). When operating a LiPo battery without undervoltage protection or
when setting too low a value, the LiPo battery is permanently damaged by deep discharge!
If the speed controller measures a battery voltage of 6.0 V in a 2-cell LiPo battery (fully charged approx. 8.4 V) and
a deactivation voltage of 3.0 V/cell for 2 seconds, the speed controller first reduces the output to 70 % and switches
off the motor after 10 seconds to prevent deep discharge of the LiPo battery. The LED at the speed controller then
emits a double flashing signal (red).
When using am NiMH-drive battery, deactivate the undervoltage recognition. Alternatively, you can set the undervol-
tage recognition to 2.6 V/cell. Deactivation takes place at a battery voltage of 5.2 V then (the speed controller does
not recognise that a NiMH driving battery is connected, but it calculates the deactivation voltage assuming that there
is a 2-cell LiPo battery).
• Function #4, green LED flashes 4x short: Start mode when driving off
Depending on this setting, the start is performed more or less powerful. The higher the set value, the more current
will the motor pull from the connected battery; it must accordingly be of higher quality.
A higher setting also should only be used on loose underground, since otherwise there will be an overload of the
drive (gear, toothed belt, differentials).
