Smart Technology ESCs

Smart Electronic Speed Controls

Using the latest advances in connectivity, Spektrum™ Smart technology ensures that all of your model’s electronics work together for the greatest efficiency and performance. Smart technology keeps you aware of every component’s status, boosts your confidence in its capabilities, and makes your entire RC system more responsive and simpler to use than ever before.

Now Firma™ surface and Avian™ air electronic speed controls join the Smart system. They not only deliver power but also eliminate the hassles from running telemetry. The days of installing and connecting multiple wires, sensors, modules and links are over. The Smart ESC gathers and transmits intelligence from other components, sending the data in real-time so you can see information like battery voltage, capacity, rpm, temperature, amp draw and more! It gives you the ability to make better decisions about your model and make needed adjustments.


No need to connect multiple wires, sensors, modules, and links. With Smart ESCs, simple one-wire telemetry transmits a wide range of data directly to your transmitter in real-time, including RPM, voltage, temperature, balance, capacity, amp draw speed and more. The Smart data wire on the innovative IC3/IC5 connector replaces sensors, sending telemetry information to the transmitter directly from the Smart ESC.


When used with a Spektrum™ Smart LiPo battery, your Smart ESC provides you with the benefit of battery telemetry that’s automatically transmitted to your compatible Spektrum radio in real-time. On your transmitter screen you’ll be presented with helpful information such as number of cycles, battery capacity used and remaining, individual cell voltage and more!


The all-weather, waterproof design of Spektrum™ Firma™ Smart ESCs allows them to perform in nearly any terrain under almost any conditions. Firma ESCs keep you going through dust, gravel, snow, and water.


Set, review, adjust and save the operating parameters of your Avian and Firma ESC using the Spektrum Smart ESC Programmer. When connected to a PC using the included USB cable, the programmer will update Smart ESC firmware and can adjust parameters through the Spektrum SmartLink app.
