LED STATUS IN NORMAL RUNNING
1. In normal use, if the throttle stick is in the neutral range, neither the red LED nor the green LED lights.
2. The red LED lights when the car is running forward or backward and it will flash quickly when the car is braking.
3. The green LED lights when the throttle stick is moved to the top point of the forward zone.
ALERT TONES
1. Input voltage abnormal alert tone: The ESC begins to check the input voltage when power on, if it is out of
the normal range, such an alert tone will be emitted: ‘beep-beep-, beep-beep-, beep-beep-’
(There is 1 second time interval between every ‘beep-beep-’ tone).
2. Throttle signal abnormal alert tone: When the ESC can’t detect the normal throttle signal, such an alert tone
will be emitted: ‘beep-, beep-, beep-’ (There is 2 seconds time interval between every ‘beep-’ tone).
PROTECTION FUNCTION
1. Low voltage cut-off protection:
A: Lipo. If the voltage of a lithium battery pack is lower than the threshold for 2 seconds, the ESC will cut of
the output power. Please note that the ESC cannot be restarted if the voltage of each lithium cell is lower than 3.5V.
B: For NiMH battery packs, if the voltage of the whole NiMH battery pack is higher than 9.0V but lower than 12V, it will
be considered as a 3S lithium battery pack; If it is lower than 9.0V, it will be considered as a 2S lithium battery pack.
For example, if the NiMH battery pack is 8.0V, and the threshold is set to 2.6V/Cell, so it will be considered as
a 2S lithium battery pack, and the low-voltage cut-off threshold for this NiMH battery pack is 2.6x2=5.2V.
2. Over-heat protection: When the temperature of the ESC is over a factory preset threshold for 5 seconds, the ESC
will cut off the output power. When the over-heat protection happens, the Green LED will flash in
such a style: ‘
g
,
g
,
g
’ (Single flash).
3. Throttle signal loss protection: The ESC will cut off the output power if the throttle signal is lost for 0.2 second.
PROGRAM THE ESC
1. Programmable Items List (The white texts in the form are the default settings)
2. Explanation For Each Programmable Item.
2.1. Running Mode:
With ‘Forward with Brake’ mode, the
car can go forward and brake, but cannot go backward, this
mode is suitable for competition; ‘Forward/Reverse with
Brake’ mode provides backward function, which is suitable
for daily training.
Note: ‘Forward/Reverse with Brake’ mode uses ‘Double-
click’ method to make the car go backward. When you move
the throttle stick from forward zone to backward zone for the
1st time (The 1st ‘click’), the ESC begins to brake the
motor, the motor speeds down but it is still running, not
completely stopped, so the backward action is NOT applied
immediately. When the throttle stick is moved to the
backward zone for the 2nd time (The 2nd ‘click’),
if the motor speed is slowed down to zero (i.e. stopped),
the backward action applied. The ‘Double-Click’ method
prevents mistaken reversing action when the brake function
is frequently used in steering.
By the way, in the process of brake or reverse, if the throttle
stick is moved to forward zone, the motor will run forward
at once.

‘Forward/Reverse’ mode uses ‘Single-click’ method to
make the car go backward. When you move the throttle
stick from forward zone to backward zone, the car will
go backward immediately.
2.2. Drag Brake Force: Set the amount of drag brake
applied at neutral throttle to simulate the slight braking
effect of a neutral brushed motor while coasting.
2.3. Low Voltage Cut-Off: The function prevents the
lithium battery pack from over discharging.
The ESC detects the battery’s voltage at any time,
if the voltage is lower than the threshold for 2 seconds,
the output power will be reduced 70%, 10 seconds later
the output will be completely stopped, and the red LED
flashes in such a style: ‘
g g
,

g g
’ (Double flashes).
2.4. Start Mode (Also called ‘Punch’):
Select from ‘Level1’ to ‘Level4’. Higher number means
more aggressive start effect.
