The Hobbywing Platinum 120A V5 Speed Control (HW30203402) is a brushless ESC for regular-voltage systems, supporting 3–8S LiPo power. It delivers 120A continuous and 150A peak current, backed by a robust switch‑mode BEC rated at 5–12V, 10A continuous (30A peak). Designed for high-performance RC applications, it brings telemetry connectivity and convenient programming options to advanced helicopter and fixed‑wing models.

With a separate programme port, support for LCD and OTA programming, and firmware upgrade capability, the Platinum 120A V5 streamlines setup and tuning. Telemetry links with popular ecosystems help monitor key parameters in flight.
