Firma Smart ESCs give you an extra layer of confidence that your electronics are all operating at their best.

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!

This ESC comes bundled with a Spektrum Firma 2250Kv Brushless Motor, which is capable of handling everything this ESC can put out and is perfect for getting you driving with Spektrum Smart technology.
