Firma 160 Amp Smart ESC with Cap (SPMXSE1160CP)

Firma 160A Smart ESC with Capacitor Pack is a high-performance electronic speed controller designed for RC vehicles, delivering power while providing real-time telemetry through the Spektrum Smart ecosystem. It combines efficient motor control with one-wire data transmission, so RPM, voltage, temperature, and capacity can be monitored on the transmitter in real time. The unit is compact, waterproof, and built for easy installation with a rugged plastic case, mounting tabs, an aluminum heat sink, and a cooling fan. It supports multiple programming options—button programming, the Smart ESC Programming Box, and the Smart Link USB PC app—so tuning at the track is quick and straightforward.

Designed for 3S to 8S operation, this ESC includes an inline capacitor pack to smooth voltage and current spikes in high-output setups, making it ideal for 8S speed runs and tough basher vehicles. It features robust protection—over-current, LiPo low-voltage cutoff, thermal, and failsafe—and a configurable high-power BEC. IC-series battery connectors provide a secure, heat-resistant connection and remain backwards compatible with EC3/EC5 systems. With firmware updatable via the provided programming tools, the Firma Smart ESC stays ready for performance improvements and on-the-fly adjustments while out on the track.
