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 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! This ESC comes bundled with a Spektrum Firma 1900Kv Brushless Motor capable of handling everything this ESC can put out that is a perfect to get you driving with Spektrum Smart technology."

This is very easy to use, The price is reasonable. It gives you power quickly and functions very well. I’m also happy it will last forever. I bought it for my camper and it was just what I needed.

It’s a 1/8 scale motor but fit my 1/10 Losi Baja Rey 2nd gen. Works well with the programmer you buy separately. Tried with a 3s lipo and was pretty fast waiting to try the 4s lipo cause the stock motor in the Baja Rey seemed faster. Overall easy to use and install. Definitely has the torque and power idk about speed yet.
