Firma 85A Brushless Smart ESC with 4000Kv Sensorless Motor Combo (SPMXSEMC02)
Spektrum Firma 85A Smart ESC with 4000Kv Sensorless Brushless Motor Combo is an all-in-one, telemetry-enabled power system for 1/10-scale, 2WD electric RC cars using 2S LiPo packs. It pairs a high-current Firma Smart ESC with a 4000Kv sensorless motor to deliver crisp throttle response and dependable power, while a one-wire telemetry link streams RPM, voltage, temperature, and battery status to a compatible transmitter in real time for on‑track tuning.
Designed for straightforward installation in typical 1/10-scale 2WD models, the unit is compact and protected by a rugged plastic enclosure with an integrated aluminum heatsink and cooling fan for efficient operation. It offers multiple programming options—button programming, the Smart ESC Programming Box, or a PC app—and a configurable high-current BEC that can run 6V or 7.4V up to 4A to power the receiver and servos. IC-series connectors provide a solid battery connection and telemetry with compatible Spektrum Smart LiPo packs, with EC3/EC5 compatibility and waterproof construction for all-weather use. Firmware updates keep performance current, and the system is ready to install with minimal setup.
