The grey values are the basic settings performed by the manufacturer at the time these operating instruc-
tions were drawn up. The speed controller of your vehicle may have a different basic setting; observe the
number of flashes of the red LED in this case.
Description of the setting functions:
• Function #1, green LED flashes 1x short: Drive function
The speed controller can be switched between „forwards/brake“ and „forwards/brake/reverse“ (reverse driving can
thus be switched off).
• 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).
Settable values are 0%, 5%, 10%, 15%, 20%, 25%, 30%, 40%.
• 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 (we
recommend at least 3.0 V per cell).
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, the speed controller first reduces the starting output or speed to 50% for 2
seconds. You can then still steer the vehicle to the edge of the route in a race. Then the speed controller switches
off the motor to avoid deep discharge of the LiPo battery.
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-drive battery is connected, but 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 take-off/start speed is more or less powerful. Note that the two settings „fast“ and
„very fast“ require a high-quality rechargeable battery capable of providing the appropriate current during take off.
These settings also should only be used with a loose underground, since gear service life is otherwise reduced
(drive pinion, main cogwheel, differentials).
