The Spektrum™ Firma 70 amp Brushed Smart ESC and motor combo is waterproof and ready to use in most 1/10th scale RC crawlers. Featuring programming options that make it easy to tune for off-road scalers and rock crawlers on or off the trail.

This ESC and Motor Combo is an excellent choice to complete your 1/10th scale off-road crawlers and scale rigs. The ESC and Motor feature industry leading tunability and accessibility, making it easy to adjust settings to get the best performance out of your crawlers, at home or on the trail.

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 motor current, temperature, battery voltage and capacity.

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. You're able to 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!
