Connect BEC wires with the receive2. Connect motor wires with ESC3. Turn on the transmitter4. Connect battery pack with ESC then switch on the ESC5. 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-beep tone7. The ESC is workableTroubleshooting:1 . If after power on , motor can , t work , no sound is emittedplease check the connections between battery pack and motor .2 . If after power on , LED flashes , please check the voltage of battery pack , which should be from 5V-13V3 . If the motor emits a " beep-beep tone Only , please check all the connections : BEC wires , transmitter and receiver , throttle signal wires , etc . please check the transmitter TH . TRIM and adjust it to the motor re-emits " beep-beep''tone4 . If the car can't be speed up , please check either voltage of the battery pack is too low or the temperature of ESC is too high . If the voltage ofthe battery pack is too low , please replace the battery pack . If the temperature of ESC is too high , please check all connections . If not ,pease push the button EPA on your remote control5 . If the car stops suddenly while in working state , please check the motors connections , and the road6 . If the car runs in the opposite direction , which the transmitter is available , please swap two wire connections between the ESC and the motor .Package List:1 x Electric Speed Controller1 x ManualNote:1.
