SPMXSEMC05, Spektrum RC Firma 150 Amp Sensorless Brushless Smart ESC & Motor Combo (2050Kv)

Spektrum Firma 150 Amp Sensorless Brushless Smart ESC & Motor Combo, with included 2050Kv motor. Like every component in the Spektrum Smart ecosystem, Firma Smart ESCs combine "plug-and-play" simplicity with the ability to communicate with other Spektrum 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. 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 RPM, temperature, battery voltage and capacity*. Firma ESCs not only gather the data, but also send it to your Smart compatible transmitter in real time, allowing the ability to adjust settings as needed to boost performance on the go.

This ESC comes bundled with a Spektrum Firma 2050Kv Brushless Motor capable of handling everything this ESC can put out that is a perfect to get you driving with Spektrum Smart technology.

*NOTE: Smart functionality requires use of Spektrum Smart compatible battery, transmitter and receiver.
