Manufacturer Description

North America Edition - Dedicated Designed for ECO / MONO1 Racing & US/Canadian Competitions

The light weight of the Pro 120A is designed to meet the users’ requirements of marine competitions in 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.


  • 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
  • Splash Proof: (IP55) 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
  • HV Built-in BEC: The built-in switch mode BEC, with a maximum output of 8A and adjustable voltage of 6V / 7.4V, makes the ESC compatible with various high voltage servos
  • 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, etc), guarantees the durability and reliability of the ESC
  • Programming/Upgrading Wirelessly: With Hobbywing’s WiFi module and an iPhone or 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
