2. Explanation for each programmable item
Running mode
With "Forward with Brake" mode, the car can go forward and brake,
but cannot go backward, this mode is suitable for competition.
"Forward/reverse with brake" mode provides backward function,
G
which is suitable for daily training.
But for ESC, "Forward/reverse with brake" mode uses the "Single-
click" method to make the car go backward.
"Forward/reverse" mode uses the "Single-click" method to make the
car go backward. When you move the throttle lever from forward
zone to backward zone, the car will go backward immediately.
Drag brake force in neutral position
Set the amount of drag brake applied at neutral throttle to simulate
the slight braking effect of a neutral brushed motor while idle speed.
Low voltage cut-off
The function prevents the lithium battery pack from over discharging.
The ESC detects the battery's voltage at any time. If the voltage is
lower than the threshold for 2 seconds, the output power will be redu-
ced 70%, 10 seconds later the output will be completely stopped, and
the red LED flashes in such a style: " ** , ** , ** " (double flashes).
Acceleration mode (also called "Punch")
Select from "Level 1" to "Level 9". A higher number means more
aggressive acceleration.
Maximum Brake Force
The ESC provides proportional brake function. The brake force is rela-
ted to the position of the throttle stick. Maximum brake force refers
to the force when the throttle stick is located at the top point of the
backward zone. A very large brake force can shorten the brake time,
but it may damage the gears.
Maximum Reverse Force
Sets how much power will be applied in the reverse direction. Diffe-
rent value makes different reverse speed.
Initial Brake Force
It is also called "minimum brake force", and it refers to the force when
the throttle stick is located at the initial position of the backward zone.
The default value is equal to the drag brake force, so the brake effect
can be very smooth.

Throttle Neutral Range
Please see the following illustrations to adjust the neutral range as
your like.
Timing
There are many differences among structures and parameters of diffe-
rent 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. Generally, higher timing value brings
out higher power output, but the whole efficiency of the system will
be slightly lower down.
Over-Heat Protection
If the function is activated, the output power will be cut-off when the
temperature of the ESC is up to a factory preset threshold for more
than 5 seconds. When the protection happens, the Green LED will
flash.
Motor Rotation
You can use this element to change the direction of rotation. Look
at the motor shaft, and move the throttle lever at the upper point of
the forward range. If this element set to "CCW" (counterclockwise),
the shaft runs against clockwise to "CW" (clockwise) the shaft runs
Clockwise.
LiPo Cells
We strongly recommend that the element "LiPo cells" to set the actu-
ally you are using LiPo batteries manually.
3. Program the ESC with the "SET" button
You'll find the instructions on the next page in the flowchart.
4. Reset all items to default values
At any time when the throttle is located in neutral zone (except in the
throttle calibration process or ESC program mode), you can hold the
"SET" key for over 3 seconds. The red LED and green LED will flash at
the same time, which means each programmable item has be reset to
its default value.
