C. Instructions

C.1 Normal Startup procedures

Step1: Pull the throttle stick to the bottom position (full Off throttle),

Step2: Switch the transmitter on,

Step3: Switch the ESC on (normally by connecting batteries).

Step4: System detects the Min. throttle signal, and makes a long “beep” sound.

Step5: System detects battery voltage and makes several short “beep” sounds, which denotes the number of

battery cells.

Step6: System conducts self-check. If it is normal, you will hear a “♪ 1 2 3” tune, push the throttle stick to start up.

(LED on the ESC will flash along with the tune.)

C.2 Throttle range setting procedures

Step1: Push the throttle stick to the top position (full On throttle),

Step2: Switch the transmitter on,

Step3: Switch the ESC on (normally by connecting batteries)

Step4: System detects the Max. throttle signal, and makes two “beep” sounds, which denotes that Max. throttle

has been confirmed and saved.

Step5: Pull the throttle stick to the bottom position (full Off throttle) within 5 seconds,

Step6: System detects the Min. throttle signal and makes a long “beep” sound.

Step7: System detects battery voltage and makes several short “beep” sounds, which denotes the number of

battery cells.

Step8: System self-check occurs. If it is normal, you will hear a “♪ 1 2 3” tune, push the throttle stick to start up.

If the system doesn’t detect the throttle signal, it will constantly make “beep” sounds without stopping.

Any fault in self-check, it will make 20 short “beep” sounds.

C.3 Protection setting

Low-voltage protection: Whether to shut down the motor immediately or to lower the power when the input

voltage drops below the programmed low-voltage protection voltage depends on the values set as Cutoff
Type.

Loss of signal protection: Power will automatically lower to 20% or less when signal is lost for 1 second, and

resume when detecting the signal.

Over-heat protection: When the temperature increases to above 110 Celsius degree, power will be lowered

gradually to less than 35% of the full power, and will resume when the temperature decreases.

Hardware self-check: The system will check by itself when the battery is connected. Any hardware fault, it will

make 20 short “beep” sounds.

E. Programmable parameters

A number of the performance parameters for the ESC are set as Default values. By using a Program Card

(available separately) or a transmitter these default values can be set to meet the users’ particular performance

requirements. The following section will deal with these factors

E.1 Brake T ype: There are three brake types including OFF (brake disable), Soft brake and Hard brake. The

default is OFF (brake disable). Soft brake: less forceful and lasts longer. Hard brake: more forceful and

lasts a shorter time.

E.2 Timing Mode: There are three options: Low, Mid and High. The default is Mid. Low advance timing is

recommended for high inductance and low KV motors. High advance timing is recommended for low

inductance and high KV motors, e.g. high KV outrunner motors. For some high KV motors, if it shakes

while rotating in high speed, the High timing mode is recommended.

E.3 Cutoff Mode: There are two options: Soft-Cut and Cut-Off. The default is Soft-Cut.

Cut-Off option: immediate motor shutdown occurs in low-voltage.
Soft-Cut option: Gradually reduce throttle power to 50% of the current power at low-voltage.

E.4 Start Mode: There are three options: Fast start, Soft start and very Soft start. The default is very Soft

start. Fast start is recommended for low inductance and low start loading motors. Very Soft start is
recommended for high inductance and high start loading motors. Soft start is recommended for those motors

with medium inductance and medium start loading.

E.5 Throttle Curve Mode: Three options: CURVE1, CURVE2, AND CURVE3 (corresponds to the OFF,

Gov-low, Gov-high of GOVERNOR

mode in the program card). The default is CURVE1.

E.6 Li-XX Cells: It is used to choose cells of Li-xx battery packs. Range : 0－12 cells. The default is 0 cell.

If the battery cell is 0, the system will automatically identify the battery cell as 0 and calculate the

Low-voltage cutoff voltage. E.g. suppose the low-voltage cutoff voltage is 2.85V per cell (under Mid

Low-voltage cutoff type), if there’re 3 cells, the total Low-voltage cutoff voltage would be 2.85*3=8.55V.

E.7 Cutoff voltage: There’re three options: Low, Middle, and High. The default is Middle.

Low: Low-voltage cutoff voltage is 2.6V per cell.
Middle: Low-voltage cutoff voltage is 2.85V per cell.
High: Low-voltage cutoff voltage is 3.1V per cell.

E.8 Motor Rotation: Options: Normal and Reverse. The default is Normal. (Programmable via using

transmitter only)

F. Programming via program card

F.1 Programming the ESC

1． Disconnect the ESC from the battery
2． Pull the PPM signal wire out from the receiver, and plug it into

the program card jack. Please pay attention to the direction

3． Connect the ESC to the battery (the first row of LED

on the program card will flash)

4． The program card automatically reads parameters

from the ESC and the corresponding LED will be on.

5． All parameters can be viewed and modified by pressing corresponding

buttons.

6． Press the “Write” button to write the new parameters to the

ESC

7． Cut off the power

F.2 Functions of each button

Button：Choose different parameters (7 in total). The corresponding LED will flash given the values chosen.

Button: Choose the value of the parameter which is currently set

Write Button: when all the parameters are set, press this button to permanently save the new parameters to the
ESC. “Write” LED will flash 3 times which indicates the setting is successfully written in.

G. Programming via Transmitter

2. Select program parameters

There’re 9 parameters can be set by using your transmitter. You would hear 9 different indicating sounds

which correspond to 9 different parameters. Pull the throttle stick to the bottom position (full Off throttle)

within 3 seconds after you hear the correspondent sound will brings you to the correspondent parameter

setting status. The indicating sounds will repeat in turn as follow (1 long sound=5short sounds):

1. “beep-” (a short sound) which indicates the Brake Type

2. “beep-beep-” (two short sounds) which indicates the Timing Mode

3. “beep-beep-beep-” (three short sounds) which indicates the Start Mode

4. “beep-beep-beep-beep-” (four short sounds) which indicates the Cutoff Mode

5. “beep-----” (a long sound) which indicates the Throttle Curve Mode

6. “beep-----beep-” (a long sound and a short) which indicates the Li-XX Cells

7. “beep-----beep-beep-” (a long sound and two short) which indicates the Cutoff V oltage

8. “beep-----beep-beep-beep-” (a long sound and three short) which indicates Motor rotation

reversible.

9. “beep-----beep-----beep-----“(three long sound) EXIT.

1. Enter program
mode

Push the throttle stick to

the top position (full On

throttle), turn on the

transmitter, connect the ESC,

wait 2 seconds, you will hear

two “beep” sounds which

means the full On throttle is

confirmed. Wait another 6

seconds, it will make “♪ i 3 i

3” tune, then you can start

programming via transmitter.

3. Select program values

After entering parameter setting status, you will hear the ESC making sounds in cycle. Different sounds

indicate different values. Push the throttle stick to the top position (full On throttle) within 3 seconds after

you hear the correspondent sound, then you will hear a special tune “♪ 5 6 5 6”, which means the

correspondent value has been chosen and saved. If you don’t want to continue setting other values, just pull

the throttle stick to the bottom position (Full Off throttle) to exit. Or wait 3 seconds to return to the second

step and continue programming.

Remarks: Under Li-XX Cells value status, when the number of Li-xx battery cell is more than 4, the ESC

will indicate by making long “beep” plus short “beep” sounds, a long “beep” sound equals 5 short “beep”

sound. E.g. you will hear “beep-----beep-” (a long sound + a short sound) if there is a 6-cell Li-xx pack and

you will hear “beep-----beep-----beep-” (two long sounds + a short sound) for a 11-cell Li-xx pack.
