Firma 160A Brushless Smart ESC for 3S to 8S (SPMXSE1160)

Firma 160A Smart Brushless ESC for 3S–8S LiPo systems is a high-performance electronic speed controller designed to power brushless motors in competitive RC models. It pairs power management with one-wire telemetry to stream RPM, voltage, temperature, and battery data directly to a compatible radio in real time. The unit is compact, waterproof, and ready to install with no soldering required, making it a practical upgrade for ready-to-run builds.

Inside, a fast 32‑bit ARM M4 processor handles precise motor control, while an aluminum heat sink and cooling fan help keep temperatures in check during intense sessions. It offers multiple programming options, including button programming, the Smart Firma ESC Programming Box, and a PC-based SmartLink USB tool, so dialing in performance at the track or on the bench is quick and easy. The ESC uses IC series connectors for a sturdy connection and is backward compatible with EC3/EC5 power leads; it also includes protections such as over-current, automatic LiPo low-voltage cutoff, thermal protection, and failsafe. When paired with a Spektrum Smart LiPo battery, the one-wire telemetry delivers battery data to the transmitter in real time, giving clearer insight and confident control over power delivery.
