Programmable Items

(The option written in bold font is the default setting)

1. Brake Setting ：Enabled / Disabled
2. Battery Type ：Lipo / NiMH
3.  Low Voltage Protection Mode(Cut-Off Mode) ： Soft Cut-Off (Gradually reduce the output power) /Cut-Off (Immediately stop the output power)
4. Low Voltage Protection Threshold(Cut-Off Threshold) ：Low / Medium / High

1. For lithium battery, the battery cell number is calculated automatically. Low / medium / high cutoff voltage for each cell is: 2.85V/3.15V/3.3V. For example: For a 3S Lipo, when “Medium” cutoff threshold is set, the cut-off voltage will be: 3.15*3=9.45V
2. For NiMH battery, low / medium / high cutoff voltages are 0%/50%/65% of the startup voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function is disabled. For example: For a 6 cells NiMH battery, fully charged voltage is 1.446=8.64V, when “Medium” cut-off threshold is set, the cut-off voltage will be: 8.6450%=4.32V 。

5.  Startup Mode ：Normal /Soft /Super-Soft (300ms / 1.5s / 3s)
   a) Normal mode is suitable for fixed-wing aircraft. Soft or Super-soft modes are suitable for helicopters. The initial acceleration of the Soft and Super- Soft modes are slower, it takes 1.5 second for Soft startup or 3 seconds for Super-Soft startup from initial
   throttle advance to full throttle. If the throttle is completely closed (throttle stick moved to bottom position) and opened again (throttle stick moved to top position) within 3 seconds after the first startup, the re- startup will be temporarily changed to normal mode to get rid of the chance of a crash caused by slow throttle response. This special design is suitable for aerobatic flight when quick throttle response is needed.

6. Timing ：Low / Medium / High,( 3.75°/15°/26.25°)
   Usually, low timing is suitable for most motors. To get higher speed, High timing value can be chosen.

Begin To Use Your New ESC

IMPORTANT! Because different transmitter has different throttle range, please calibrate throttle range before flying.
Throttle range setting (Throttle range should be reset whenever a new transmitter is being used)

Switch on the t r ansmi tte r, move throttle stick to the top position

| Connect battery pack to the
ESC, and wait for about 2 seconds| The “Beep-Beep-” tone should be emitted, means the top point of throttle range has been confirmed| Move throttle stick to the bottom position, several “beep-” tones should be
emitted to present the  amount of battery cells| A long “Beep-” tone should be emitted, means the
lowest point of throttle range has been correctly
confirmed
---|---|---|---|---

Normal startup procedure

Move throttle stick to bottom position and then switch on transmitter.| Connect battery packto ESC, special tonelike “ 123” meanspower supply is OK| Several “beep-” tones should be emitted to present the amount of lithium battery cells| When self-test is finished, a long
“beep—–” tone should be emitted| Move throttle stick upwards to go flying
---|---|---|---|---

Protection Function

1. Start up failure protection: If the motor fails to start within 2 seconds of throttle application, the ESC will cut-off the output power. In this case, the throttle stick MUST be moved to the bottom again to restart the motor. (Such a situation happens in the following cases: The connection between ESC and motor is not reliable, the propeller or the motor is blocked, the gearbox is damaged, etc.)
2. Over-heat protection: When the temperature of the ESC is over about 110 Celsius degrees, the ESC will reduce the output power.
3. Throttle signal loss protection: The ESC will reduce the output power if throttle signal is lost for 1 second, further loss for 2 seconds will cause the output to be cut-off completely.

Trouble Shooting

Replace the connector.
After power on, motor does not work, such an alert tone is emitted:
“beep-beep-, beep-beep-,beep-beep-” (Every “beep-beep-” has a time intervalof about 1 second)| Input voltage is abnormal, too high or too low.| Check the voltage of battery pack
After power on, motor does not work, such an alert tone is emitted:
“beep-, beep-, beep- ”(Every “beep-” has a time interval of about 2 seconds)| Throttle signal is irregular| Check the receiver and transmitter
Check the cable of throttle channel
After power on, motor does not work,such an alert tone is emitted:
“beep-, beep-, beep-” (Every “beep-” hasa time interval of about 0.25 second)| The throttle stick is not in the bottom (lowest) position| Move the throttle stick to bottom position
After power on, motor does not work, aspecial tone “ ” is emitted after 2beep tone (beep-beep-)| Direction of the throttle channel is reversed, so the ESC has entered
the program mode| Set the direction of throttle channel correctly
The motor runs in the opposite direction| The connection between ESC and the motor need to be changed.| Swap any two wire connections between ESC and motor

Program the ESC with your transmitter (4 Steps)

Note: Please make sure the throttle curve is set to 0 when thethrottle stick is at bottom position and 100% for the top position.

1.  Enter program mode
