Thanks for purchasing our
Electronic Speed Controller (ESC). High power system for RC model is very dangerous, please read
this manual carefully. In that we have no control over the correct use, installation, application, or maintenance of our products,
no liability shall be assumed nor accepted for any damages, losses or costs resulting from the use of the product. Any claims
arising from the operating, failure or malfunctioning etc. will be denied. We assume no liability for personal injury, property
damage or consequential damages resulting from our product or our workmanship. As far as is legally permitted, the
obligation to compensation is limited to the invoice amount of the affected product.
Features
1.
4 speed controllers in1board, only 1 pair of battery wire is needed.
2.
Powerful switch mode built-in BEC (the BEC voltage outputs from the S3 connector).
3.
Multiple protection features: Low voltage cut-off protection / over-heat protection / throttle signal loss protection.
4.
The throttle range of each ESC can be calibrated to be suitable for different multi-rotor flying control systems / transmitters.
5.
Maximum speed: 210000 RPM (2 poles motor), 70000 RPM (6 poles motor), 35000 RPM (12 poles motor).

3.
Low Voltage Protection Mode (Cut-Off Mode)
：
Soft Cut-Off (Gradually reduce the output)
/Cut-Off (Immediately stop the output)
4.
Low Voltage Protection Threshold (Cut-Off Threshold)
：
Low
/ Medium / High
a)
For lithium battery, the battery cell amount is calculated automatically. Low / medium / high cutoff voltage for each cell is:
2.85V/3.15V/3.3V. For example: For a 3S Lipo battery, when
“Medium” cutoff threshold is set, the cut-off voltage will be:
3.15*3=9.45V
b)
For NiMH battery, low / medium / high cutoff voltages are 0% / 50% / 65% of the startup voltage (i.e. the initial voltage of
battery pack), and 0% means the low voltage cut-off function is disabled. For example: For a 6 cells NiMH battery, fully
charged voltage is 1.44*6=8.64V
, when “Medium” cut-off threshold is set, the cut-off voltage will be 8.64*50%=4.32V
。
Warning!
In order to protect the expensive multi-rotor, the default settings (i.e.
Battery Type
= “NiMH” and
Cut-Off Threshold
=
“Low”) don’t take any protection even if the Lipo battery is over discharged. If you do need to activate the battery protection function
please change the default settings.
5.
Startup Mode
：
Normal
/Soft /Super-Soft (300ms / 1.5s / 3s)
The initial acceleration of the Soft and Super-Soft modes are slower than the Normal mode, it takes 1.5 second for Soft startup or 3
seconds for Super-Soft startup from initial throttle advance to full throttle. If the throttle is completely closed (throttle stick moved to
bottom position) and opened again (throttle stick moved to top position) within 3 seconds after the first startup, the re-startup will be
temporarily changed to normal mode to get rid of the chance of a crash caused by slow throttle response. This special design is
suitable for aerobatic flight when quick throttle response is needed.

Usually, the default timing is suitable for most motors. To get higher speed, High timing can be chosen.
Begin To Use Your New ESC
Because different transmitters / flying control systems have different throttle ranges, please calibrate the throttle range for each speed
controller before flying.
The Throttle Signal HUB is recommended for calibrating the throttle ranges for 4 speed controllers simultaneously instead of one by one.
Throttle range setting:
Note:
The throttle range of each speed controller in the Quattro should be set separately. When the Quattro is installed in a multi-rotor,
you should set the throttle range of each ESC via the flying control system.
