Battery
Receiver
ESC
Motor
*Please ensure all solder joints are insulated with
heat shrink where necessary.
( 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
( 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.
Trouble

“Beep beep beep…”
continuous urgent shor t tone
Warning Tone
“Beep,beep,beep…”
shor t interval tone
“Beep-beep,beep-beep-beep,…Beep--beep--”
Circular tones
Possible Cause
The throttle stick is not at the bottom
position or throttle range is too small.
No output signal from the throttle
channel on the receiver.
The”Normal/Reverse”direction of the
throttle channel on transmitter is incorrect.
Solution
Move the throttle stick to the bottom position 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 setting of
“Normal/Reverse”direction of the throttle channel.

1Normal star t-up Process
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 shor t tone.
It means the ESC is ready for working.
ATTENTION
Turn on the
transmitter,
move the
throttle stick to
the top position.
Connect the receiver to
the batter y, 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-
BEEP",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.
Please set throttle range,
when first time to use ESC
or change transmitter.
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.
The motor will
emit different
tone circularly.
“Beep-beep-”Throttle rage;
“Beep-beep-beep-” 15° timing
“Beep-beep-beep-beep-”18.75° timing
“Beep--” 22.5° timing
“Beep--beep-” 26.25° timing
Wait for 2 seconds, motor
emits continuously 1 long
and 1 short tone. It means
the ESC is ready for working.
Move the throttle stick to the
bottom position in 3 seconds
after hearing corresponding
tone, the setting will be
completed.
Star t-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 restar t the motor.( The possible causes : Bad connection or disconnection between ESC & motor , propellers are blocked, etc)
Over-load
Protection
Throttle Signal
Loss 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.
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.
Blocking
Protection
When the motor / blade due to contact with foreign objects blocking, ESC will stop immediately, to prevent the high-speed rotation of the blade caused
personal injury. (when the throttle is less than 10%, the protection is invalid).
