Specification: Item Type: 25A ESC Material: Plastic + Alloy Color: Red Black Continuous Current: 25A Maximum Current: 100A Motor Type: Sensorless brushless motor 1. Highway: KV <7200KV 24xx size or smaller engine 2. Off-road/: KV <4800KV 24xx size or smaller engine Resistance: 0.0014 ohm Battery: 2S lipid battery / 4-6 battery section BEC Output: 5.0V / 2A (analog mode) Size: Approx. 40 x 32 x 15mm / 1.6 x 1.3 x 0.6in Compatibility: Suitable for 1/16, 1/18, 1/20 RC car Instructions: 1.Connect the BEC wire to the receiver. 2.Connect the motor wire with ESC. 3.Turn on the transmitter. 4.Connect the battery pack to the ESC, then turn on E. 5.When the motor is connected to the battery, it makes a beep-beep-beep-beep-beep-beep. 6.When the throttle lever is in neutral, the motor will beep again 7.ESC works. Trouble Removal: 1.Check the connection between the battery pack and the motor if the motor does not work and no sound is emitted. 2.If the power indicator flashes, check the voltage of the battery pack, which should be 5V-13V.Signal line, etc.Please check the transmitter TH.Adjust and adjust until the motor starts beeping again. 3.If the motor makes a beep sound only, check all connections: the BEC wire, the transmitter and the remote control. 4.If it cannot be accelerated, please check the battery voltage is too low or the electric adjustment temperature is too high. If the battery voltage is too low, please replace the battery.If the electrical temperature is too high, check all connections.If not, press the EPA button on your remote control. 5.If the car stops suddenly while in service, check motor connections and roadblocks 6.If the car is going in the opposite direction (a transmitter can be used), exchange two wires between the electric regulator and the motor.. Package List: 1 x 25A Waterproof ESC 1 x Manual Note: 1. Please allow 1‑3mm error due to manual measurement. Thanks for your understanding.2. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.3. Remove the cooling fan before using the ESC in water; Clean and dry immediately after use to prevent the connector from rusting.
