The Spektrum Avian Smart 40A Dual Brushless ESC is the perfect upgrade for 3S-6S twin EDF jets and other twin-powered models. Like other Spektrum Avian ESCs, this ESC delivers power and intelligence all-in-one. Without additional sensors or modules, they feed battery and ESC telemetry data straight to your radio in real time, all over one connection.

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 vehicle imaginable.

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

With Avian 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. An Avian electronic speed control provides a one-wire solution for obtaining telemetry data such as RPM, temperature, battery voltage and capacity.

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!

No need to connect multiple wires, sensors, modules, and links. With Avian™ ESCs, simple one-wire telemetry transmits a wide range of data directly to your transmitter in real time, including current, voltage, cell balance, temperature and RPM.
