Spektrum Firma 150A Brushless Smart ESC V2, 3S–6S: Dual IC5
Part of the Spektrum Smart ecosystem, the Firma 150A Brushless Smart ESC V2 goes beyond basic speed control to function as a virtual engineer for your vehicle, delivering real-time telemetry like RPM, temperature, and battery voltage straight to your transmitter. Its single-wire Smart telemetry solution eliminates the need for extra wires, modules, or links, keeping installation clean while giving you live data you can act on mid-run instead of only reviewing after the fact. A fast 32-bit ARM M4 processor handles signal input and motor output with high precision, while a fully waterproof design lets the ESC perform through dust, gravel, snow, and water. With multiple programming options and no soldering required, the Firma Smart ESC is built for racers who want plug-and-play simplicity backed by serious performance data.
