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.
