In normal cases, Low or Medium timing can be suitable for most motors. In order to get higher speed, try the High timing value.
Note: After you changing the timing setting, please test your RC model on ground firstly!
【Begin To Use The New ESC】
Before using your new ESC, please check all the connections to make sure that they are reliable, and then start up the ESC in the
following sequence:
1. Move the throttle stick to bottom, and then switch on the transmitter.
2. Connect the receiver battery pack (4-6V) to the receiver, and then connect the main power battery pack to ESC, the ESC begins
the self-test process, and the motor will emit several “beep” tones to represent the number of lithium battery cells. After 2 seconds a
long “beep------”tone will be emitted, which means the self-test is OK, and now the RC model is ready to go flying.
 If nothing is happened, please check your battery packs and all the connections;
 If a special tone “
” is emitted after 2 beep tones (beep-beep-), means the ESC has entered the program mode, i.e. the
throttle channel of your transmitter is reversed, please set it correctly on the transmitter;
 If a very rapid “beep-beep-, beep-beep-” tone is emitted (The time interval of each “beep-beep-” tone is 1 second), means the
input voltage is too low or too high, please check your battery’s voltage.
3. VERY IMPORTANT! Because different transmitter has different throttle range, you need to use the “Throttle Range Setting
Function” to calibrate the throttle range. Please read the instructions on page 2------“Throttle Range Setting”.
【Alert Tone】
1. Input voltage abnormal alert tone: The ESC begins to check the voltage of battery pack when it is power on, if the voltage is not in
the acceptable range, such an alert tone will be emitted: “beep-beep-, beep-beep-, beep-beep-” (Every “beep-beep-” has a time
interval about 1 second)
2. Throttle signal abnormal alert tone: When the ESC can’t detect the normal throttle signal, such an alert tone will be emitted: “beep-,
beep-, beep-”. (Every “beep-” has a time interval about 2 seconds)
3. Throttle stick is not at its bottom position alert tone: When the throttle stick is not in the bottom (lowest) position, a very rapid alert
tone will be emitted: “beep-, beep-, beep-”. (Every “beep-” has a time interval about 0.25 second.)
【Protection Function】
1. Start up protection: If the motor failed to start up in 2 seconds while the throttle stick is being moved up, the ESC will cut off the
output power. In this case, the throttle stick MUST be moved to bottom again to restart the motor. (Such a situation happens in the
following cases: The connection between ESC and motor is not reliable, propeller is blocked, gearbox is damaged, etc.)
2. Over-heat protection: When the temperature of ESC is higher than a factory-preset value, the ESC will reduce the output power.
3. Throttle signal lost protection: The ESC will reduce the output power if the throttle signal is lost for 1 second, further lost for totally 2
seconds will cause its output to be completely cut off.
【Normal Startup Procedure】
Please note that we use a special way to represent the number of lithium battery cells: 1 long “beep—” = 5 short “beep-”.
For example, 2 long “beep—” plus 2 short “beep-” (Beep—Beep—BB) means a 12 cells lithium battery pack, 1 long “beep—” plus 1
short “beep-” (Beep—B) means a 6 cells lithium battery pack.
【Throttle Range Setting】 Throttle range should be reset when a new transmitter is being used
【Trouble Shooting】
Trouble Possible Reason Action
After power on, motor can’t work, no
sound is emitted
The connection between battery
pack and ESC is not OK
Check the power connection.
Replace the connector.
After power on, motor can’t work, such
an alert tone is emitted:
“beep-beep-, beep-beep-,beep-beep-”
(Every “beep-beep-” has a time interval
about 1 second)
Input voltage is abnormal, too high
or too low
Check the voltage of battery pack
After power on, motor can’t work, such
an alert tone is emitted:
“beep-, beep-, beep- ”(Every “beep-” has
a time interval about 2 seconds)
Throttle signal is abnormal Check the receiver and transmitter
Check the cable of throttle channel
After power on, motor can’t work, such a
alert tone is emitted:
“beep-, beep-, beep-” (Every “beep-” has
a time interval about 0.25 second)
Throttle stick is not in its bottom
position (Lowest position).
Move the throttle stick to bottom
Switch on the
transmitter, and
then move the
throttle stick to
bottom position
Connect the battery
pack to ESC, a special
tone like “ 123” will
be emitted, means the
power supply is OK
When self-test is
finished, a long
“beep— ” tone will
be emitted
Ready to go
flying now
Several “beep-” tones will
be emitted to represent
the number of lithium
battery cells
Switch on the
transmitter,
and move the
throttle stick
to top position
Connect the
battery pack to
the ESC, and
then wait for
about 2 seconds
“Beep-beep-” tone will
be emitted, means the
highest point of the
throttle range has been
correctly confirmed
Move the throttle stick to the
bottom position, and then
several “beep-” tones will be
emitted to represent the
number of Lipo battery cells
A long “Beep-” tone will be
emitted, means the lowest
point of the throttle range
has been correctly
confirmed.
