The Spektrum Firma 70A Brushed Smart ESC is waterproof and ready to use in most 1/10th scale RC models. Featuring programming options that make it easy to tune for your on-road and off-road racers, scalers, crawlers, and bashers. Firma™ Smart ESCs combine plug-and-play simplicity with the ability to communicate with other Smart electronics.

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, giving you an extra layer of confidence that your electronics are all operating at their best. 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 — letting you adjust settings on the go. The Firma Smart single-wire telemetry solution has been tested for quality and performance by the best brands in RC.
