Overview

The Spektrum 40 Amp Brushed Smart ESC is waterproof and can be used in most 1/10 scale RC models. It features programming options that allow for easy tuning for your on and off-road racers, scalers, crawlers and bashers.

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 RC system for your vehicle imaginable.

Firma Smart ESCs do much more than just regulate power. They act like a virtual engineer in your model, providing a direct path to the vital operating data you need to achieve peak performance. Firma Smart ESCs give you the peace of mind that your electronics are working optimally.

With Firma Smart ESCs, you are better connected to your vehicle than ever before - without having to install additional components that all work independently of each other. You don't need additional wires, modules or connections. A Firma electronic speed controller provides a one-wire solution for collecting telemetry data such as motor current, temperature, battery voltage and capacity.

Firma's ESCs not only collect the data, but also send it to your transmitter in real time instead of just storing it for post-run investigation. You can adjust the 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 easier and better!
