2. Over-heat protection: When the internal temperature of the ESC is higher than 100 ˚C 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.
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 zone to backward zone for the first time, the ESC 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.
TROUBLE SHOOTING
Problem
• 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.

Reaction
• 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.
"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").
CHARGING/INSTALLING THE BATTERY.
Always store your model with
the battery pack unplugged and
removed. Always charge your
battery away from the vehicle.
The included 500mAh mains
charger will take approx 3-4
hours to charge a fully discharged
battery, but always remove it from
the charger if it becomes warm to
the touch. Always disconnect the
charger from the mains supply
and the battery pack when not in
use.
Keep children away from charger and battery during the charging process.
Notes on Battery use:
Always allow the battery cool after use, before recharging.
Always inspect the battery before charging.
Any bare wires, split heat shrink or leakage is a sure sign of abuse.
Never attempt to charge dead or damaged batteries.
Do not disassemble the battery or cut the connector wires.
If the battery connector gets hot enough to melt there is most likely a serious
problem with your model, driveline, battery wires or speed controller. Find and
correct the problem before installing another charged battery pack.
NEVER charge the battery unattended incase of overcharging, you need to be
able to monitor the battery during charging
Charge away from flammable objects and on a non-flammable surface incase
the battery becomes too hot.
Solution
• 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.
