Turn on the transmitter, move the

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

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

in 3 seconds.
Wait
for 2 seconds, motor
emits continuously 1 long and

Attention
：
Please
calibrate

( When motor emits tone 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

.
Check if the communication is normal between
transmitter and receiver; Check throttle channel
connection well.
Refer to the transmitter instruction and adjust the
setting
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.
