New in box Spektrum Firma 150A brushless smart ESC / 2050Kv Sensorless Motor Combo. 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.
