Spektrum™ Smart Technology Video Overview

Spektrum Firma 150A Smart ESC for surface vehicles is waterproof and delivers power and intelligence all-in-one. Without additional sensors or modules, they feed battery and ESC telemetry data straight to your radio in real-time, all over one connection. Now includes a compatible 4000Kv Firma Brushless Sensorless motor when you purchase the combo.

Like every component in the Spektrum™ Smart ecosystem, Firma™ Smart ESCs combine "plug-and-play" simplicity with the ability to communicate with other Smart electronics — together, creating the best-performing RC system for your vehicle imaginable.

Firma Smart ESCs do much more than regulating power. They function as a virtual engineer inside your model, providing a direct path to the vital operating data you need to reach peak performance. Firma Smart ESCs give you an extra layer of confidence that your electronics are all operating at their best.

With Firma Smart ESCs, you'll be better connected to your vehicle than ever before — without installing extra components that all work independently of each other. You won't need extra wires, modules, or links. A Firma electronic speed control provides a one-wire solution for obtaining telemetry data such as RPM, temperature, battery voltage and capacity.

Firma ESCs gather the data and send it to your transmitter in real-time instead of only storing it for an after-run study. You're able to adjust settings as needed to boost performance on the go. The Firma Smart single-wire telemetry solution has been tested for quality and performance by the best brands in RC. Their verdict? Smart technology is both simpler and superior!

Spektrum Firma Waterproof Smart ESC
Spektrum Firma EC3/EC5 Backwards Compatible

The all-weather, waterproof design of Spektrum™ Firma™ Smart ESCs allows them to perform in nearly any terrain under almost any conditions. Firma ESCs keep you going through dust, gravel, snow, and water.

Ec3™/Ec5™ Backwards Compatible

Firma™ ESCs feature IC™ series battery connectors. The IC series of connectors are designed from the ground up to provide a more solid connection, higher heat resistance, and effortless installation. When used with an IC3™ or IC5™ connector-equipped Spektrum™ Smart battery, the ESC can receive and transmit battery telemetry data. EC3 and EC5 are also compatible with Firma ESCs for basic operation and ESC telemetry.

One-Wire Telemetry

No need to connect multiple wires, sensors, modules, and links. With Firma™ ESCs, simple one-wire telemetry transmits a wide range of data directly to your transmitter in real-time, including RPM, voltage, temperature, balance, capacity, and speed.
