The Hobbywing Platinum 120A V5 3-8S Brushless ESC w/ 5-12V SBEC is a high-performance aircraft speed controller designed for demanding RC helicopter and fixed-wing applications. Built with Hobbywing’s Platinum V5 technology, it delivers strong 120A continuous current handling, smooth throttle response, reliable power delivery, and advanced programmability for serious electric aircraft setups.

This ESC supports 3-8S LiPo power systems and features a built-in switch-mode SBEC with adjustable 5-12V output, making it suitable for high-power servo and receiver setups. Hobbywing lists the BEC output at 10A continuous / 30A peak, with support for a maximum adjustable voltage of 12V.

The Platinum 120A V5 uses a compact double-sided heat dissipation design with an internal air duct structure to help improve cooling efficiency. It also includes Hobbywing’s DEO driving efficiency optimisation technology, designed to improve throttle response, efficiency, flight stability, battery life, and ESC temperature control.

Suitable for 420-520 class electric helicopters or compatible fixed-wing aircraft, this ESC also supports firmware upgrades, LCD Program Box programming, OTA Programmer compatibility, and telemetry protocols including Mikado VBar and Futaba S.Bus2.
