Troubles
Possible Causes
Solutions
After power on, no LED
lights up, no self-test and no
beep sound.
1. No power is drawn to the ESC.
2. The switch of the ESC is broken.
1. Check the connections between battery and ESC.
Re-solder the connectors if needed.
2. Change the ESC switch.
After turn on, the RED LED
blinks but the motor doesn’t
work.
1. Throttle wire is wrongly plugged
or into the incorrect channel.
2. The ESC can’t successfully
complete the throttle range
self-calibration.
1. Plug the throttle signal wire correctly (in right direction) into
the throttle channel (usually Ch2) of the receiver.
2. Set the “TRIM” of throttle channel to 0 or turn the knob to
its neutral position.
The car runs backwards
when accelerating forward
on the transmitter.
1. The direction setting of the
throttle channel is incorrect in the
transmitter or the motor wires are
wrongly connected.
1. Reverse the direction of the throttle channel, from the
original “NOR” to “REV” or “REV” to “NOR”.
2. Swap any two wires between the ESC and motor.
The vehicle can’t reach to
the full speed even at the full
throttle, and the RED LED
doesn’t keep lighting.
1. There are some incorrect settings
in the transmitter.
1. Set D/R, EPA, ATL to 100% for the throttle channel or turn
the knobs to maximum value. Set TRIM to 0 or turn the
knob to its neutral position.
Vehicle can’t reverse.
1. The corresponding jumper is
plugged into the wrong position.
2. Neutral point of the throttle is
drifted or deviated.
1. Insert the jumper into the right location.
2. Set the “TRIM”of the throttle channel to 0 or turn the knob
to its neutral point.
Motor suddenly stops
running.
1. The throttle signal is lost.
2. The low voltage cutoff protection
or thermal protection (i.e. over
heat protection) of the ESC is
activated.
1. Check the connections between ESC and receiver. Check
the transmitter and receiver). Check whether the battery
voltage of the transmitter is too low.
2. The RED LED on the ESC blinks, denoting the ESC is
under low voltage cutoff protection or over-heat protection.
Please check the ESC temperature, if it is too hot, please
let the ESC cool down.
If the battery voltage is low, please change the battery.
The Vehicle neither go
forward no reverse, but the
LED indicators work
normally.
1. The connection between ESC
and motor is interrupted.
2. The motor is damaged.
1. Check the connectors between the motor and ESC to
ensure all connections are firm and reliable.
2. Replace a new motor.
The motor accelerates
rapidly at the startup
moment, but has lockout or
cogging problem.
1. The discharge capacity of the
battery is not strong enough.
2. The motor rotates too fast, and
the gear ratio is too aggressive.
3. Something wrong with the
driveline of the vehicle.
1. Change a battery with better discharge capability.
2. Use a motor with lower RPM, or smaller pinion to soften
the gear ratio.
3. Check the driveline of the vehicle.
