Firstly, the user must understand the performance of the remote control , the range and direction of throttle
control what’s your purposes for the model you are handling For different purpose it has different setting for the
model
Set throttle with gun-type remote control
Cut off the main power supply of ESC, turn on the power
supply of transmitter and receiver Pull the transmitter
throttle to the end(Max of the throttle),connect the
main power of ESC and wait for 2S ,the motor will make 3 sound of BEEP
like“∮∮__∮∮__∮∮” When hearing the third sounds, please loose
the throttle to the middle (if you set full throttle, pull to the highest of
reverse direction )When motor makes 1 sound ∮,the set of throttle trip has finished and stored in the ESC
Wait for 2S, motor will make single sound for many times After the single sound, It will make 2 continuous
sound∮∮ At this time, it shows ESC has been ready Motor can work by increasing the throttle
Set throttle with Panel-type remote control
●Cut off the main power supply of ESC, turn on the power
supply of transmitter and receiver Pull the transmitter
throttle to the end(Max of the throttle),connect the
main power of ESC and wait for 2S ,the motor will make 3 sound of BEEP
like“∮∮__∮∮__∮∮” (it shows the Max throttle is ensured by ESC )When hearing the third sounds, please loose
the throttle to the middle (if you set full throttle, pull to the highest of reverse direction )When motor makes 1 sound
∮,the set of throttle trip has finished and stored in the ESC Wait for 2S, motor will make single sound for many times
After the single sound, It will make 2 continuous sound∮∮ At this time, it shows ESC has been ready Motor can work
by increasing the throttle
：If losing the signal of receiver during the operation, the output of motor will be cut off in 1S and makes sound of
BEEP “∮__”with interval 1S
( but PCM receiver lose the signal of transmitter , it will keep the normal control signal, ESC won ’t provide the
sound through motor at this time )
※ For gun-type remote control and panel-type remote control , ESC support the set of half throttle trip It can set the
Maximum –Minimum The maximum – every position where between middle throttle and the Max position (when
using the panel remote control without being back to the middle automatical ,the residence time of the maximum
throttle setting should wait for the end of the sound of battery test For security, if the throttle is pushed when the
throttle is lower the middle the throttle, the present position should be as the lowest position Please pay attention to
it )
III Start up
》a Push the throttle to the lowest ( two-way throttle back to the middle)
If ESC has connected in circuit, please check if ESC connects battery pack If connected battery pack, please
disconnect the battery pack
》b Connect ESC with battery pack

Positive and negative rotation with brake: reverse function is available when push the throttle from forward
direction to the reverse zone, Ship model is in the braking state, the throttle must return to the middle, And the
motor stops operating then reversing, this mode is mainly used for training .
Direct positive and negative rotation: When push the throttle from the middle point region to the reverse
zone, the motor reverses immediately .
★ 2 Designated region in the throttle
The designated region of the throttle are 6%, 9%, 12%, you can choose according to personal preference after
experiments
★ 3 Battery low voltage protection
To prevent the lithium battery from over-discharge damage, the ESC will monitor the battery voltage all the
time during operation, once the battery voltage is below the set value, the motor output will be cut off
★ 4 Start acceleration
9 levels in total, the default is 6 levels , select the appropriate acceleration, according to the area and personal
habit, the higher level the faster start, but a high requirement for the discharge capacity of the battery,(if high
level
with insufficient battery capacity, it may cause abnormal start, then please reduce the level ) it’s difficult to
operate
★ 5 Maximum reverse force
4 kinds of options: 25%, 50%, 75%, 100%, different option has different reverse force, it is recommended to
use a less option, to avoid collision because the strength is too big to control hard when reversing
★ 6 Entrance angle setting
0 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees (the default), 25 degrees,30 degrees,
automatic optional
The role of this function:

Compatible with different motors, this motor can’t operate normally in the default entrance angle, need to adjust into
the right entrance angle before work properly

By adjusting the entrance angle, you can fine-tune the motor output speed, the higher the entrance angle, the higher
maximum output speed, and power consumption is greater

By adjusting the entrance angle, the motor can work in the best efficiency point

Auto entrance angle can adjust entrance angle automatically between 0-30 degree according to the motor speed ,user
can use this angle as it’s simple setting
Announcements
●When controlling the system, please note if the ESC is approved by CE
●Properties of electrical or mechanical like bad technology may cause the unconscious operation of the motor,loose
parts may cause serious personal injury or property damage
●The ESC is specifically used for RC(remote control) model Manned aircraft is prohibited
●Do not reverse the power supply batteries’ polarity of ESC when connecting(＋side and －side flip) if the polarity of
the battery pack connected to the ESC reverse, it will cause irreparable damage
●Electronic equipment is sensitive to moisture, if the ESC is wet , please do some dry processing or contact us to give
guidance
●The ESC must connect to standard power strictly, if the voltage of the power is too high, the ESC will be damaged, if
too low, it won’t work normally

●When turning off the battery of receiver, please note: Depending on the receiver you are using, it will send false
throttle signal to the ESC, which will shortening the lifetime of the motor
●Protect the ESC from mechanical load, vibration, dust and pollution
●The length of motor cable should be as short as possible, can not exceed stated maximum length of the cable
between the batteries and the ESC The inside wiring of the battery pack must be as short as possible Embedded way
connected to the battery pack
●Although some ESC use On/Off Switch to separate from the battery, but it can’t completely insulate with the battery
the function of the ESC can be revealed with full use Only in good handling state can protect and monitor the circuit
●In the case of motor fault(like coil short circuit),controller's over-temperature sensors responds is very slow in the
prevention of damage turn off the motor Immediately to prevent permanent damage to the ESC
Note: Keep in mind that the circuit monitor can not detect each of the abnormal operation, like the broken of motor
cable if the motor's stop current higher than the controller's peak current, the stall motor will hinder current limiter For
example, if you connect 80A ESC with 20A motor, although the motor is stalling, the current monitor can not detect
excess current
●Interference
We think that some interference is related to the types of motor The the occurrence of interference is related to different
manufacturers of motor
5. Tips should be pay attention and fault handling table
Failure phenomenon Possible reason Solution
when power on, motor does not
work,come with
“BEEP--,BEEP--”warning
sounds (（Each group of dual
sounds' time interval is 1second)
The battery packs' voltage is not
in the normal range
Check the battery voltage
increase the throttle of remote
control in the forward
direction,Ship move in the
opposite direction
1 The ESC output lines and
motor Line are connected in
wrong order
2 Maybe the problem of positive
and negative control
Settings
1 If it is senseless motor，exchange every
two of the three connect line,or solve the
problem as below
2 Change the positive and negative
control Settings
Motor suddenly stopped in the
process of running
1 Receivers meet interference
2 The ESC is on the condition
of battery low voltage protection
or temperature protection
1 Rule out interference and power on to
start up again
2 Replace the battery, use again until the
temperature drop
When motor startup quickly
increase the throttle ，motor
come with the problem like
Stick or pause
1 The battery discharge ability
is not enough
2 Motor running speed is too
high ，reduction ratio is too
small
3 The ESC start acceleration set
is too high
1 Replace a high ability battery
2 Exchange to low speed motor or
improve the reduction ratio。
3 Set the ESC start acceleration softer。
