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)

Competition Design

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.

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 Voltage
Built-in BEC

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.

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.
