1. Brake Type
1.1 Normal Brake
After selected this option, the brake function will be activated when you move the throttle stick to the bottom position. In this mode, the brake amount
equals to the brake force you’ve preset.
1.2 Reverse Brake
A
fter selected this option, the Reverse Brake signal wire (its signal range must be the same as the throttle range) must to be plugged into any vacant channel
on the receiver, and you can control the motor direction via that channel. The channel range of 0-50% is the default motor direction, and the channel range
of 50% to 100% will cause the motor to spin counterclockwise. The channel stick should be within the channel range of 0-50% (0 would be better) when
the first time you power on the ESC. After the Reverse function is activated, the motor will stop first and then spin in the reversed direction and then
increase to the speed corresponding to the throttle input. Either signal loss, no matter reverse brake signal loss or throttle signal loss during the flight, can
cause the throttle signal loss protection to be activated.
2. Brake Force
This item is only effect in the “Normal brake” mode ,The higher the level, the stronger the braking effect , where the low/medium/high corresponds to the
braking force: 60/80/100%
3. Voltage Cutoff Type
3.1 Soft Cutoff
After selected this option, the ESC will gradually reduce the output to 50% of the full power in 3 seconds after the low-voltage cutoff protection is
activated.
3.2 Hard Cutoff
After selected this option, the ESC will immediately cut off the output when the low-voltage cutoff protection is activated.
4. LiPo Cells:
The ESC will automatically calculate the number of LiPo cells you have plugged in as per the “3.7V/Cell” rule if “Auto Calc.” is selected, or
you can set this item manually.
5. Cutoff Voltage
If set off, the low-voltage protection function is disabled. In addition, the protection voltage value of the low-voltage protection function corresponding to
the low/medium/three modes is about 2.9V/ section, 3.2V/ section and 3.5V/ section. This value is the voltage of a single battery, multiplied by the number
of lithium batteries automatically identified by the electronic governor or the number of lithium batteries manually set, which is the protection voltage value
of the battery. (For example, if the low voltage protection threshold of 3 lithium batteries is medium, the protection voltage of the batteries is 3X3.2=9.6V)
6. Start-up Mode
6.1 Normal Start-up
After selected this option, the motor will immediately start spinning and then quickly reach to the corresponding speed when you move the throttle stick
from bottom position to top position.
6.2 Soft Start-up
After selected this option, the motor will slowly start spinning and then quickly reach to the corresponding speed when you move the throttle stick from
bottom position to top position.
7. Timing
Can adjust the drive motor timing value. The low / Medium and high are respectively: 5°/15°/22°.
8.
Active Freewheeling (DEO)
This item is adjustable between “Enabled” and “Disabled”, and it is enabled by default. With it enabled, you can have better throttle linearity or smoother
throttle response.

Solutions
The ESC didn’t work after it was
powered on while the motor kept
beeping.
“BB, BB, BB……”
The input voltage was beyond
the operating voltage range of
the ESC.
Adjust the power-on voltage and ensure
it’s in the operating voltage range of the
ESC.
The ESC didn’t work after it was
powered on while the motor kept
beeping.
“B-, B-, B-, B-……”
The ESC didn’t receive any
throttle signal from the receiver.
Check if the transmitter and receiver are
well bound, if any poor connection exists
between the ESC and receiver.
The ESC didn’t work after it was
powered on while the motor kept
beeping.
“B, B, B, B……”
The throttle stick has not been
moved to the bottom position.
Move the throttle stick to the bottom
position and calibrate the throttle range.
The ESC didn’t work after the throttle
calibration while the motor kept beeping.
“B, B, B, B……”
The throttle range you set was
too narrow.
Re-calibrate the throttle range.
The ESC output suddenly reduced to
50% during the flight, the motor kept
beeping after the flight completed but the
battery was still connected to the ESC.
“BB, BB, BB……”
The ESC thermal protection has
been activated
Improve the heat dissipating condition (i.e.
add a cooling fan) or reduce the ESC load.
The ESC output suddenly reduced to
50% during the flight, the motor kept
beeping after the flight completed but the
battery was still connected to the ESC.
“BBB, BBB, BBB……”
The
low-voltage
cutoff
protection has been activated.
Change another pack; lower down the
cutoff voltage or disable the LVC
protection (we do not recommend this).
Multiple Protections
1. Start-up Protection:
The ESC will monitor the motor speed during the start-up process. When the speed stops increasing or the speed increase is not stable, the ESC will take it
as a start-up failure. At that time, if the throttle amount is less than 15%, the ESC will try to restart automatically; if it is larger than 20%, you need to move
the throttle stick back to the bottom position first and then restart the ESC. (Possible causes of this problem: poor connection/ disconnection between the
ESC and motor wires, propellers are blocked, etc.)
2. ESC Thermal Protection:
The ESC will gradually reduce the output but won’t cut it off when the ESC temperature goes above 110℃. For ensuring the motor can still get some power
and won’t cause crashes, so the maximum reduction is about 50% of the full power. The ESC will gradually resume its maximum power after the
temperature lowers down. In addition, the ESC temperature cannot exceed 70℃ when it’s powered on. Otherwise, it cannot be started up. (Here we are
describing the ESC’s reaction in soft cutoff mode, while if in hard cutoff mode; it will immediately cut off the power.)
3. Throttle Signal Loss Protection:
When the ESC detects loss of signal for over 0.25 second, it will cut off the output immediately to avoid an even greater loss which may be caused by the
continuous high-speed rotation of propellers or rotor blades. The ESC will resume the corresponding output after normal signals are received.
4. Overload Protection:
The ESC will cut off the power/output or automatically restart itself when the load suddenly increases to a very high value. (Possible cause to sudden load
increase is that propellers are blocked.)
III. Select Parameter Values
The motor will beep different kinds of beeps
circularly, move the throttle stick to the top
position after you hear some kind of beeps will
get you to the corresponding parameter value,
then you’ll hear the motor emit “

indicate the value is saved, then get back to
