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” 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 “Brushed” ESC, and 100% for the
“Brushed-Crawler” ESC.

TROUBLE SHOOTING
】
Trouble
Possible Reason
Solution
After power on, motor can
’t work, no
sound is emitted, and LED is off.
The ESC doesn’t get its working
voltage; Connections between
battery pack and ESC are
broken.
Check the battery wires connection
or replace the defective connectors.
Switch is damaged.
Replace the switch.
After power on, motor
can’t work; red
LED blinks.
Throttle signal is abnormal.
Check the throttle wire connection;
make sure it is plugged into the
throttle channel of the receiver.
Automatic
throttle
range
calibration is failed.
Set the “TRIM” of throttle channel to
0 or turn the knob to its neutral
position.
The car runs backward while giving
throttle.
(The motor runs in the opposite
direction)
The wire connections between
ESC and the motor need to be
changed.
Swap two wire connections between
the ESC and the motor.
The car can’t go backward.
The jumper position is wrong.
Check the jumper and plug it to the
correct position.
The neutral point of throttle
channel is changed or drifted.
Set the “TRIM” of throttle channel to
0 or turn the knob to its neutral
position.
The car
can’t go forward, but can go
backward.
The direction of throttle channel
is not correct.
Reset the direction of throttle
channel from original “NOR” to
“REV”, or from original “REV” to
“NOR”.
The motor doesn’t work, but the LED in
the ESC works normally.
The connections between motor
and ESC are broken.
Check the connections and replace
the defective connectors.
Motor is damaged.
Replace the motor.
The motor suddenly stops running
while in working state
The throttle signal is lost.
Check the transmitter and the
receiver.
Check the throttle wire connection.
Low voltage cut-off protection
or Over-heat cut-off protection
has been activated.
Replace the battery pack, or cool
down the ESC.
The car cannot get top speed and the
red LED doesn’t solid on at full throttle
Some setting in the transmitter
are incorrect.
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.
Motor is cogging when accelerated
quickly.
The
battery
has
limited
discharge ability.
Use battery with better discharge
ability.
Motor RPM is too high, the gear
ratio is too aggressive.
Use motor with lower RPM, or use
smaller pinion to get softer gear
ratio.
Something wrong in the driving
system of the car.
Check the driving system of the car.
