【BEGIN TO USE THE NEW ESC】
WARNING! THIS BRUSHLESS SYSTEM IS VERY POWERFUL! FOR SAFETY, PLEASE ALWAYS KEEP THE
WHEELS AWAY FROM THE TRACK WHEN YOU BEGIN TO SWITCH ON THE ESC.
A) Sensored brushless motor wiring
When using brushless motor with Hall Sensor，
please connect the motor and the ESC with a
sensor cable.
WARNING! For sensored brushless motor,
the #A, #B, #C wires of the ESC MUST be
connected with the motor wire #A, #B, #C
respectively. Do not change the wires
sequence optionally!
B) Sensorless brushless motor wiring
When using brushless motor without Hall
Sensor, the #A, #B, #C wires of the ESC can
be connected with the motor wires freely
(without any sequence). If the motor runs in the
opposite direction, please swap any two wire
connections.

2. Throttle Range Setting (Throttle Range Calibration)
In order to make the ESC fit the throttle range, you must calibrate it when you begin
to use a new ESC, or a new transmitter, or change the settings of neutral position of
the throttle stick, ATV or EPA parameters, etc. Otherwise the ESC cannot work
properly.
The following pictures show how to set the throttle range with a Futaba
transmitter.
A) Switch off the ESC, turn on the transmitter,
set the direction of throttle channel to "REV",
set the "EPA/ATV" value of throttle channel to
"100%", and disable the ABS function of your
transmitter.
B) Hold the "SET" key and then switch on the
ESC, and release the "SET" key as soon as
possible when the red LED begins to flash.
(Note2 )
If you don't release the "SET" key as soon as the red LED begins to flash, the ESC will enter the program mode,
Note2:
in such a case, please switch off the ESC and re-calibrate the throttle range again from step A to step D.
C) Set the 3 points according to
the steps shown in the pictures
on the right side.
1) The neutral point
Move the throttle stick at the
neutral point, and then click the
SET key, the green LED
flashes 1 time.
2) The end point of forward
direction
Move the throttle stick at the
end point of forward direction,
and then click the SET key, the
green LED flashes 2 times.
3) The end point of backward
direction
Move the throttle stick at the
end point of backward
direction, and then click the
SET key, the green LED
flashes 3 times.
D) Throttle range is calibrated;
motor can be started after 3
seconds.
3. Check The LED Status In Normal Running
► Normally, if the throttle stick is located in the neutral range, neither the red LED nor the green LED lights.
► The red LED lights when the car is running forward or backward and it will flash quickly when the car is braking.
► The green LED lights when the throttle stick is moved to the top point of the forward zone.
4. Check The Lipo Cells Setting If You Are Using Lithium Battery
If you are using Lipo battery, we strongly suggest setting the programmable item # 12 --- "Lipo Cells" manually to avoid the
over-discharge problem. Please read the instructions on page 2.
In normal case, when the ESC is switched on, the motor will emit several "Beep" tones to express the cells amount of the
battery pack. For example, "Beep-Beep-" means 2S Lipo, "Beep-Beep-Beep-" means 3S Lipo, etc.
