Spektrum Firma 150A V2 Brushless Smart ESC for 6S is a high‑performance electronic speed controller that powers brushless motors in large‑scale RC vehicles while delivering real‑time telemetry directly to a compatible Spektrum radio via a single wire. As part of the Firma Smart ecosystem, it combines robust power management with smart data sharing, giving you instant feedback on RPM, voltage, temperature, and capacity to help optimize performance on the fly.

Designed for easy field installation with no soldering, this ESC features a rugged plastic housing, an aluminum heatsink, and a cooling fan for efficient cooling, plus an adjustable high‑power BEC. It offers multiple programming options—button programming, the Smart ESC Programming Box, and a Smart Link USB PC app—and is waterproof for all‑weather use. IC series connectors are supported (backwards compatible with EC connectors), enabling straightforward integration with compatible batteries and gear, while one‑wire telemetry keeps vital data flowing to the transmitter.
