Special Design for 1/12th Scale Top Racing
Reliable hardware combined with great software (contains 5 common ready-to-use profiles)
creates an ideal power solution to1/12th scale top touring car racing.
Special Design for 1/12th
Scale Top Racing
Small Size & Light Weight
Height of 15.9mm (6mm shorter than the previous V3.1 1S ESC) saves space and makes the
installation convenient; weight of 35.6g (12g lighter than the previous V3.1 1S ESC)
provides more weight margin when adjusting the balance of the chassis.
Small Size &
Internal BEC features booster circuitry can output the current/voltage of up to 6A/6V and
power various servos without connecting any extra receiver battery.
Built-in Electronic Switch & Capacitor Module
The built-in electronic switch with a lifespan of over 50000 on/off cycles
completely solves the problems like stuck reed, rusted contact points, and
automatic shutdown conventional mechanical switches often have.The internal
capacitor module saves space and makes the wiring simple and neat.
Built-in Electronic Switch &
With Hobbywing’s “WiFi Express” module and iPhone or an Android phone (with the HOBBYWING WiFi Link
software installed), the user can remotely program parameters, upgrade firmware and
check relevant data of the ESC without leaving the control stand.

Adjustable Throttle & Brake PWM Frequencies
Independent and adjustable throttle & brake PWM frequencies guarantee precise and accurate
throttle and brake control for all classes of competitions (esp. the Stock class).

Separate Programming/Fan Port
The separate PRG/FAN port on the ESC can power an external fan to maximize cooling performance
or connect the ESC to a LCD program box or WiFi module for ESC programming.

Innovative Data-logging Function
This ESC features the data-logging function which can record the maximum ESC/motor
temperature, RPM and etc. in real time and allows users to check those
data via a LCD program box or WiFi module after each use.

The neutral throttle value stored on your ESC is different from the one stored on the transmitter, please calibrate or re-calibrate the throttle range.
1)1)If the throttle control cable has been plugged in the improper channel on the receiver.
2)2)If the throttle control cable has been reversely plugged in the TH channel on the receiver.
3)3)The ESC firmware is lost; please return it to factory for after-sales service.
1)1)Check if the wire connections between the ESC and motor are A-a, B-b, and C-c.
2)2)Check if there is any poor connection/soldering between the ESC and motor.
3)3)The ESC/motor is damaged. Run some tests with a good ESC/motor to confirm the issue and then contact the dealer for after-sales service.
1)1)You incorrectly set the throttle direction on the transmitter, so please adjust the TH direction from "NOR" to "REV" or from "REV" to "NOR".
2) 2)Check if the differential(s) has/have been reversely mounted on the chassis.
The Red LED flashes a single flash that repeats indicating the low-voltage cutoff protection is activated; please change the battery pack.
The Green LED flashes a single flash that repeats indicating the ESC thermal protection is activated; you need to cool the ESC down before using it again.
The Green LED flashes a double flash that repeats indicating the motor thermal protection is activated, you need to cool the motor down before using it again.
The Red & Green LEDs flash at the same time indicating the ESC has automatically switch the Sensor Mode to Sensorless Mode; please check if the sensor cable or motor has any problem.
1)1)Improper connection. A separate 3-pin port marked with "-/+/S" on the ESC is programming port. And you cannot connect your ESC to the LCD program box or WiFi module via the throttle control cable.
2) 2)The firmware of the program box is not compatible with this ESC, please update the firmware.
3)The ESC is not compatible with this program box; it's only compatible with the multifunction LCD program box and the WiFi module.
