THE DIFFERENCE BETWEEN “BRUSHED” AND
“BRUSHED-CRAWLER & BOAT” ESC
1. “Brushed” and “Brushed-Crawler& Boat” ESCs have different backward-running modes.
“Brushed” ESC uses “Double-Click” method to make the car go backward. When you move
the throttle stick from forward one to backward one for the rst time, the begins to
brake the motor, the motor speeds down but still running, so the backward action is NOT
happened at this moment. When the throttle stick is moved to the backward zone again
(The 2nd “click”), if the motor speed is slowed down to zero (i.e. stopped), the backward
action will be activated. The “Double-Click” method prevents mistakenly reverse when the
brake function is frequently used in steering.
“Brushed-Crawler& Boat” ESC uses “Single-click”
to make the car go backward. When you move the
throttle stick from forward zone to
backward zone, the car will go
backward immediately. This
mode is common for the Rock
Crawler and tank.
2. The maximum reverse
force (for backward
running) is 50% for the
general “Brushed” ESC,
100% for the “Crawler”
mode of a “Brushed-
Crawler & Boat” ESC, and
25% for the “Boat” mode
of a “Brushed-Crawler &
Boat” ESC.
3. The Low Voltage Cut-off
Protection modes are different (Please check the
instructions in the section of “PROTECTION FUNCTIONS”).

(Crawler or Boat mode).
. verheat protection hen the internal temperature of the is higher than
or 212 Fahrenheit degree for 5 seconds, the ESC will reduce and cut
off the output power.
When the car stops, the red
LED blinks to indicate the
over-heat protection has
been activated. If the ESC
cools down to 80 Celsius
degree (176 Fahrenheit
degree) the output power
is recovered to normal
state.
3. Throttle signal loss
protection: The ESC
will cut off the output
power if the throttle
signal has been lost for
0.1 second. The “Fail Save”
function of the radio system
is strongly recommended to be
activated.
• After power on, motor can’t work, no sound is emitted,
and LED is off.
• After power on, motor can’t work; red LED blinks.
• The car runs backward while giving throttle.
(The motor runs in the opposite direction).
• The car can’t go backward.
• The car can’t go forward, but can go backward.
• The motor doesn’t work, but the LED in the ESC works
normally.
• The motor suddenly stops running while in working state.
• The car cannot get top speed and the red LED doesn’t
solid on at full throttle.
• Motor is cogging when accelerated quickly.
• The ESC doesn’t get its working voltage; Connections
between battery pack and ESC are broken.
• Switch is damaged.
• Throttle signal is abnormal.
• Automatic throttle range calibration is failed.
• The wire connections between ESC and the motor need to
be changed.
• The jumper position is wrong.
• The neutral point of throttle channel is changed or drifted.
• The direction of throttle channel is not correct.
• The connections between motor and ESC are broken.
• Motor is damaged.
• The throttle signal is lost.
• Low voltage cut-offprotection or Over-heat cut-off
protection has been activated.
• Some setting in the transmitter are incorrect.
• The battery has limited discharge ability.
• Motor RPM is too high, the gear ratio is too aggressive.
• Something wrong in the driving system of the
car.
• Check the battery wires connection or replace the
defective connectors.
• Replace the switch.
• Check the throttle wire connection; make sure it is
plugged into the throttle channel of the receiver.
• Set the “TRIM” of throttle channel to 0 or turn the knob to
its neutral position.
• Swap two wire connections between the ESC and
the motor.
• Check the jumper and plug it to the correct position.
• Set the “TRIM” of throttle channel to 0 or turn the knob to
its neutral position.
• Reset the direction of throttle channel from original “NOR”
to “REV”, or from original “REV” to “NOR”.
• Check the connections and replace the defective
connectors.
• Replace the motor.
• Check the transmitter and the receiver.
• Check the throttle wire connection.
• Replace the battery pack, or cool down the ESC.
• Check the settings. Set D/R, EPA, ATL to 100% or turn the
knobs to maximum value. Set TRIM to 0 or turn the knob
to its neutral position.
• Use battery with better discharge ability.
• Use motor with lower RPM, or use smaller pinion to get
softer gear ratio.
• Check the driving system of the car.
Problem Reaction Solution
Output cuts off at
6.5V.
If the throttle stick
moves to neutral
and then up again,
the output can be
recovered to 50%.
If the voltage drops
to 6.5V again, the
above process
repeats in circles.
Output cuts off at
9.75V.
If the throttle stick
moves to neutral
and then up again,
the output can be
recovered to 50%.
If the voltage drops
to 9.75V again,
the above process
repeats in circles.
Output cuts off
at 13V.
If the throttle stick
moves to neutral
and then up again,
the output can be
recovered to 50%.
If the voltage drops
to 13V again, the
above process
repeats in circles
Output cuts off at
4.5V.
If the throttle stick
moves to neutral
and then up again,
the output can be
recovered to 50%.
If the voltage drops
to 4.5V again, the
above process
repeats in circles.
