Competition Design
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)

Splash-proof
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.


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.


Programming/Upgrading Wirelessly
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.


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.
