The car ran forward/backward slowly when the throttle trigger was at the neutral position. Re-calibrate the throttle range or fine tune the neutral position on the transmitter. The neutral position on the transmitter was not stable, so signals were not stable either. The vehicle could run forward (and brake), but could not reverse. Contact the distributor for repair or other customer services. Set the “running mode” to “Forward/Reverse with Brake”. No LED on the ESC will come on when the throttle trigger is at the neutral position. Re-calibrate the throttle neutral position. The throttle neutral position on your transmitter was actually in the braking zone. Check all soldering points, please re-solder if necessary. The ESC was damaged (some MOSFETs were burnt). Some soldering between the motor and the ESC was not good. The motor suddenly stopped or significantly reduced the output in operation. The GREEN LED keeps flashing indicating the thermal protection is activated, please let your ESC cool down before using it again. The RED LED keeps flashing indicating the LVC protection is activated, please replace your pack. Check all devices and try to find out all possible causes, and check the transmitter’s battery voltage. The ESC entered the thermal (over-heat) protection. The ESC entered the battery LVC (Low Voltage Cutoff) protection. The receiver was influenced by some foreign interference. The vehicle ran backward when you pulled the throttle trigger towards you. Your chassis is different from popular chassis.
The (ESC-to-motor) wiring order was incorrect. After the ESC was powered on and finished LiPo cells detection (the GREEN LED flashed N times), and then the RED LED flashed rapidly. Re-calibrate the throttle range after you release the throttle trigger to the neutral position. Check if the throttle wire is reversely plugged in or in the wrong channel and if the transmitter is turned on. The neutral throttle value stored on your ESC is different from the value stored on the transmitter. The ESC didn't detect any throttle signal.
The ESC was unable to start the status LED, the motor, and the cooling fan after it was powered on. Check if all ESC & battery connectors have been well soldered or firmly connected. Tr o u b l e ( s ) Solution(s) Possible Causes 1.
