This is the Spektrum Avian 45-Amp Brushless Smart ESC with IC3 plug (EC3 compatible) for 3S-6S LiPo power.

Like every component in the Spektrum Smart ecosystem, Avian 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 aircraft imaginable.

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

With Avian Smart Air ESCs, you'll be better connected to your aircraft than ever before -  without installing extra components that all work independently of each other. You won't need extra wires, modules, or links. An Avian electronic speed control provides a one-wire solution for obtaining telemetry data such as current, voltage, cell balance, temperature and RPM.

Avian 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 Avian 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!
