Timing

Turn on the transmitter, move the 
throttle stick to the bottom position

Connect ESC & battery packs, wait

 

for 2 seconds, motor emits 

continuously 1 long and 1 short tone. It means the ESC is ready 
for working.

Turn on the 
transmitter, 
move the
throttle stick to
the top position.

Connect  the  receiver  to

the  battery,  ensure  the

communication is normal

between  the  transmitter

and receiver, then power

on the ESC.

Wait  for  2  second,  after 
motor emits 2 short "BEEP-
B E E P ",move  the  throttle 
stick  to  the  bottom  position 
in 3 seconds.

Wait

 

for  2  seconds,  motor 

emits continuously 1 long and 
1 short tone. It means the ESC 
is ready for working.

Attention

Please 

calibrate

when first time to use ESC or change transmitter.

Wait

 

for  2  seconds,  motor 

emits  continuously  1  long

the ESC is ready for working.

Turn on the 
transmitter,

on the ESC.

The motor will 
emit different
tone circularly.

Move the throttle stick

in 3 seconds after 
hearing corresponding

timing

( When motor emits tone times 

5 times, long " Beep--" will represent 5 times) 

When ESC drives disc type motor with accelerating  throttle , motor may be out-of-step ,
stalling or requires higher speed , you could try to change timing (  ESC factory default
 value is 22.5°). Higher timing can accelerate motor speed, but also cause more heat. 
After changing timing, please test on the ground before flying.

● 

Start-up Protection:

 ESC will cut off output if it fails to start the motor within 3 seconds by accelerating throttle. you need to move the throttle stick 

    back to the bottom position and restart the motor.( The possible causes :  Bad connection or disconnection between ESC & motor , propellers are 
    blocked, etc)

● 

Over-load Protection:

 ESC will cut off power or output when the load suddenly increases to a very high value, normal operation will resume after 

    moving the throttle stick to the bottom position. ESC will automatically try to restart when ESC and motor are out-of-step.

● 

Throttle Signal Loss Protection:

 

When ESC detects the loss of throttle signal for over 0.32 seconds, it will cut off power or output immediately to 

    avoid an even greater loss caused by the continuous high speed rotation of propellers. ESC will resume the corresponding output after the normal 
    signal is restored.

Solution

Move the throttle stick to the bottom

or

 

reset

 

the

 

throttle range

.

Check if the communication is normal between 

transmitter and receiver; Check throttle channel 

connection well.

Refer to the transmitter instruction and adjust the

of “Normal/Reverse”direction of the throttle 

channel.

 ESC can not work under water. Reasonable use of ESC can prolong the service life

.

Splash-proof and corrosion resistant, please clean 

 

    up the water and stains on the ESC

 

after a certain period of time , to avoid electric short circuit.

 The programming cable is only for the factory download firmware,  user is prohibited from using this cable.

 User need to calibrate the throttle range when starting to use a new ESC or change another transmitter.

● 

When some abnormality occurs in ESC driving the motor or need the motor to reach a higher RPM, user can try to change the timing.
