Spektrum™ Firma™ 85A Brushless Smart ESC for surface vehicles is waterproof and delivers power and intelligence all in one. Without additional sensors or modules, it feeds battery and ESC telemetry data straight to your radio in real-time, all over one connection.
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, 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 the vital operating data you need to reach peak performance. Firma Smart ESCs give you more confidence that your electronics are all operating at their best.
With Firma Smart ESCs, you'll be better connected to your vehicle than ever without installing extra components that work independently. You won't need additional 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 storing it for an after-run study. You can 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!
