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, creating the best-performing RC system for your vehicle. Firma Smart ESCs do much more than regulate power — they function like a virtual engineer inside your model, providing a direct path to 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. No extra wires, modules, or links are needed. A Firma ESC 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, rather than only storing it for after-run study, so you can adjust settings as needed to boost performance on the go.
