3. Thermal Protection:
The output throttle from the ESC will be limited (not over 
50 % )   with  the  thermal  value  you  have  preset . ( The 
Thermal   protection   will  be  dismissed  when  the  ESC 
temperature drop to 65℃)
4. If t he  voltage  protection and temperature protection 
set off, and  when  the  voltage and temperature become 
abnormal ,  the  LED  status  will  indicates  the  problems 
correspondingly ,  but  will  not  limit the  throttle  output 
and will not close all ESC timing.
5.  If   the   ESC   detected  the  motor  have  the   driving 
problem  ( like  motor  rotor  locked  or motor phase lost 
problem)  which can  cause  the  motor not run smoothly, 
and  when   the   throttle  trigger  leave  neutral  position 
for  a  while,  then  the  ESC  driving abnormal protection 
will  be  activated, and  the motor will  emit  special  tone 
like  beep-beep-beep ( note:  some motors can not beep 
or  beep  with  a  low  sound  if  motor  have   phase  loss 
problem ),  and  the  protection  will  be  closed until you 
released  the  throttle  trigger to  neutral  position for 0.2 
seconds. If this problem occurs three times continuously, 
then  you have to  solve  the motor driving problem  

rst,

or the protection will exist all the time.

2. With RCOMG Bluetooth, connected the RCOMG  app 

to the  ESC, the user can program parameters, upgrade 

f irmware  and check the real-time data of the ESC on the 

APP.

3. Due  to the  range limit of  Bluetooth, the operational 

distance is around 10 meters.(If there are many metals or 

other  strong  interference  signals  or obstacles around 

will short the operational distance)

4. The Bluetooth name can not be changed.

5. The  Bluetooth  connecting  will  be  failed during the 

ESC throttle calibration process.

Bluetooth

1.  Reset  password :  When  the  ESC  turns on,  press  and 

holding  the power button around 10 seconds, the ESC will 

restore  the  Bluetooth  password  to  default  setting 0000.

1. The user can program parameters at any status if the 

ESC turns on, and new programmed parameters will be 

took effect immediately, no need to restart the ESC, it 

means the programming parameters can be competed 

online, so it can provide a very intuitive feeling between 

the before programming and after programming. 

There will be some impacts on the battery/ESC/motor 

if you program some parameters when the motor in a 

high-speed rotation. For example, if you changed the 

motor rotation when the motor in a high-speed rotation, 

then the ESC will drive the motor reverse immediately, 

but the motor can not be reverse immediately because 

of its inertia, then it will cause a big current and vibration. 

Or when the Boost or Turbo timing opened, but you set
