The light-weight of the Pro 120A is designed to meet the users’ requirements of a light
weight product for all marine competition which weight is a factor of speed and
endurance. The core program for top-level competition products guarantees the user
first-class control and “abundant” programmable parameter items for different
competition environments. (* The ESC is especially applicable to ECO/MONO1)
The whole circuit board and all the components on it have gone through nano-coating
treatment; this makes the Seaking Pro 120A ESC splash-proof.
High Voltage Built-in BEC
The built-in switch mode BEC with a maximum output of 8A and adjustable
voltage of 6V/7.4V make the ESC compatible with various high voltage servos.
High Durability & Reliability
Reliable hardware (i.e. MOSFETs with extremely low internal resistance) combined with advanced
software (features low-voltage cutoff protection, thermal protection, throttle signal loss protection, and
etc) guarantees the durability and reliability of the ESC and relevant electronic devices.
High Durability & Reliability
Innovative Turbo Function
The world’s first marine ESC to have implemented the turbo timing function
which will give the user the edge over the competition with instant turbo boost.
With Hobbywing’s WiFi module and iPhone or an Android phone (with the
HOBBYWING WiFi Link software installed), the user can remotely program
parameters or upgrade firmware without leaving the control stand.
Wifi Express module
Efficient Cooling System
The Hobbywing patented heat-conductive copper bar cover on the power board
of the ESC combined with the water cooling module efficiently and effectively
transfers heat to the outside thus keeping your ESC as cool as possible.
Regular Firmware Updates Free of Charge
You can upgrade the ESC with the Hobbywing WiFi/USB LINK software, a WiFi
module/LCD program box and a smartphone /laptop. Hobbywing updates its ESC
firmware regularly giving you upgraded features more often when available.

Manuals & Documents
Because the ESC didn’t detect any correct throttle signals then, so please check the following items:
1)If the throttle control cable has been plugged in the improper channel on the receiver.
2)If the throttle control cable has been reversely plugged in the TH channel on the receiver.
3)The throttle stick hasn't been moved to the neutral position or the bottom position, or the neutral position or the bottom position has not been set properly, please reset the throttle range.
The Red LED flashes a single flash that repeats indicating the low-voltage cutoff protection is activated and you need to change the battery pack.
The Green LED flashes a single flash that repeats indicating the ESC thermal protection is activated, you need to cool the ESC down before using it again.
1)Improper connection. Please plug the throttle control cable (White/Red/Black tri-color) into the power port (marked with "+/-") and the Turbo Acceleration wire (Yellow) into the port (marked with "S/+/-") on the LCD program box, connect the ESC to a battery, and then press any button on the program box.
2)The ESC is not compatible with the LCD program. You can only program it via a multifunction LCD program box or WiFi module.
3)The firmware of the program box is out-dated; please update it to the latest version.
