Firma 150A Brushless Smart ESC with Sensorless 2050KV Motor (SPMXSEMC05)

Spektrum Firma 150A Smart ESC and 2050KV sensorless motor bundle is a high‑performance, all‑in‑one power system designed for RC cars and other models that support Spektrum Smart technology. This combo pairs a 150A brushless Smart ESC with a sensorless 2050KV motor to deliver strong, responsive power with real‑time telemetry via a single wire to your transmitter. Developed by Spektrum engineers in collaboration with a leading ESC manufacturer, the system emphasizes reliability and easy integration across a range of vehicles.

It’s built to endure in challenging conditions, featuring waterproof construction and a compact, rugged enclosure with mounting tabs, plus an aluminum heat sink and cooling fan to keep temperatures under control. The package includes backward‑compatible EC3/EC5 connectors, high‑heat IC connectors, an adjustable high‑power BEC, and firmware update options via the Smart ESC Programming Box or the Smart Link USB PC Programmer. One‑wire telemetry streams data such as RPM, voltage, temperature, battery balance, and capacity directly to the transmitter in real time, and when used with a Spektrum Smart LiPo battery it can also report cycles and remaining capacity. The kit includes the 150A Smart ESC, the 2050KV motor, a sticker sheet, and a product manual, and is backed by a 1‑year limited warranty.
