The values highlighted in grey are the manufacturer's default settings at the time of drawing up these op-
erating instructions. The speed controller of your vehicle may have a different default setting; in this case,
note the number of flashing signals of the red LED.
Overview of functions:
• Function #1, green LED flashes one time briefly: Drive function
The speed controller can be switched between the two drive modes ("forwards/brake" and "forwards/brake/
reverse").
In "forwards/brake" mode, the reverse function can be disabled. This is often required in racing competitions.
• Function #2, green LED flashes two times briefly: Brake
If you release the throttle on the transmitter or move the throttle/brake lever on the transmitter back to the neutral
position, the vehicle will slow down by itself. The effect is just like the motor braking function on a "real" car when
you release the accelerator pedal without pressing the brake pedal.
The brake functions like a brake on a standard electric motor (a brushless electric motor does not have strong
magnets that slow down the rotor).
• Function #3, green LED flashes three times briefly: Low voltage protection
If a LiPo drive battery is used, make sure that the undervoltage protection is enabled (we recommend at least 3.2 V
per cell). If you use a LiPo rechargeable battery without undervoltage protection, it will be permanently damaged
by deep discharge!
If the speed controller with a 2-cell LiPo drive battery (fully charged approx. 8.4 V) and a cut-off voltage of 3.2 V per
cell detects a battery voltage of 6.4 V, it will switch off the motor to prevent deep discharge of the LiPo drive battery.
When using a NiMH drive battery, you should disable the undervoltage protection. Alternatively, set the undervolt-
age protection to 2.6 V per cell.
If the voltage of a NiMH drive battery is below 9 V after the speed controller is turned on, the speed controller will
interpret this as a 2-cell LiPo rechargeable battery. Shutdown would then occur at 5.2 V (2 x 2.6 V).
If the voltage of a 6-cell NiMH drive battery is above 9 V (for example, for rechargeable batteries with a
relatively high voltage level or batteries that have just been charged), the speed controller will interpret this
as a 3-cell LiPo rechargeable battery. Motor shutdown would then occur at 7.8 V (3 x 2.6 V), which is of
course undesirable. In this case, overvoltage protection should be disabled.
