Connect BEC wires with the receive 2. Connect motor wires with ESC 3. Turn on the transmitter 4. Connect battery pack with ESC then switch on the ESC 5. When the connection of motor and battery is finished, the motor emits"beep-beep tone. 6. When the throttle stick is In the neutral position, the motor re-emits"beep" 7. The ESC is workable Motor Installation and Maintenance: 1. lf replacing the motor mounting screws , use the same type and size that your vehicle was equipped withoriginally。 2.Do not over-tighten the motor mounting screws .

Troubleshooting: 1. After power on, if the motor fails to work and no sound is emitted, please check the connection between the battery pack and the motor. 2. If the motor emits a "beep", please check all connections: BEC cable, transmitter and receiver, throttle signal cable, etc. Please check the transmitter for TH.TRIM and adjust it so that the motor beeps again. 3. If the car cannot accelerate, please check whether the battery voltage is too low or the temperature of the ESC is too high. If the battery voltage is too low, please replace the battery. If the temperature of the ESC is too high, please check all connections. If it is not, press the EPA button on the remote control. 4. If the car suddenly stops under working conditions, please check the motor connection and roadblocks 5. If the car is driving in the opposite direction to the transmitter, please swap the two wire connections between the ESC and the motor. Motor specifications: ESC uses jumper cap to set the BEC voltage to 7.4V or 6.4V, and set the track model to ON or OFF.
