Product Overview
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 regulate power. They function like 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 not only gather the data but also send it to your transmitter in real time, instead of only storing it for 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!

EC3â„¢/EC5â„¢ BACKWARDS COMPATIBLE
Firmaâ„¢ ESCs feature ICâ„¢ 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 IC3â„¢ or IC5â„¢ connector-equipped Spektrumâ„¢ 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.
Â
SMART TECHNOLOGY BATTERY DATA
When used with a Spektrumâ„¢ Smart LiPo battery, your Firmaâ„¢ ESC provides you with the benefit of battery telemetry that's automatically transmitted to your compatible Spektrum radio in real time. On your transmitter screen you'll be presented with helpful information such as number of cycles, battery percentage, individual cell voltage and more!
