【DECLARATION】

Thanks for purchasing HOBBYWING “EZRUN” series Electronic Speed Controller (ESC). High power

system for RC model can be very dangerous, so please read this manual carefully. In that we have no

control over the correct use, installation, application, or maintenance of our products, no liability shall be

assumed nor accepted for any damages, losses or costs resulting from the use of the product.

【FEATURES】

1. Specially designed for RC car and truck, with excellent start-up, acceleration and linearity features.

2. Compatible with sensorless brushless motor.

3. 3 running modes suitable for different applications (“Forward with brake” mode, “Forward/Backward with

brake” mode and “Rock crawler” mode).

4. 4 steps of maximum reverse force adjustment.

5. Proportional ABS brake function with 4 steps of maximum brake force adjustment, 8 steps of drag-brake force

adjustment and 4 steps of initial brake force adjustment.

6. 9 start modes (“Punch”) from “Soft” to “Very aggressive” to be suitable for different chassis, tires and tracks.

7. Multiple protection features: Low voltage cut-off protection for lithium or nickel battery / Over-heat protection /

Throttle signal loss protection / Motor blocked protection.

8. 8 steps of timing adjustment.

9. User programmable. Several program methods are supported, such as: The “SET” button on the ESC, the

digital LED program card, the advanced LCD program box, the PC software, etc. The program card and

program box are pocket-sized and they have friendly user interface to be easily used.

1) For 4-6 cells NiMH or 2 cells Lipo: You needn’t change the fan combined with the ESC;

2) For 7-9 cell NiMH or 2 cells Lipo: You must change the fan combined with the controller

because it cannot work with such a high voltage, so please choose a high voltage fan or supply

the fan from the receiver (+5V); (*Note1)

Note1: For information about the high voltage cooling fan,

please refer to the brief introduction on page 3.

【BEGIN TO USE THE NEW ESC】

1. Connect the ESC, motor, receiver, battery and servo

according to the following diagram

“+” and “-” wires of the ESC are connected with the battery

pack, and #A, #B and #C are connected with the motor wires.

The “SET” button is used for programming the ESC.

The control cable of the ESC (trio wires with black, red and

white color) is connected with the throttle channel of the

receiver (Usually CH2).

The #A, #B, #C wires of the ESC can be connected with the

motor wires freely (without any order). If the motor runs in the

opposite direction, please swap any two wire connections.

Note: You can use the transmitter to set the throttle

channel to the “Reverse” direction, and then the motor

will run oppositely. Please calibrate the throttle range

again after changing the direction of throttle channel.

Throttle Range Setting (Throttle Range Calibration) In order to make the ESC fit the throttle range, you must calibrate it for the following cases; otherwise the ESC cannot work properly. 1) Begin to use a new ESC; 2) Begin to use a new transmitter; 3) Change the settings of neutral position of the throttle stick, ATV or EPA parameters, etc. There are 3 points need to be set, they are the top point of “forward”,” backward” and the neutral point.

Timing: There are many differences among structures and parameters of different brushless motors, so a fixed timing ESC is difficult to compatible with all brushless motors. It is necessary to make the timing value programmable. Please select the most suitable timing value according to the motor you are just using.
