Product Overview

Like every component in the Spektrum Smart ecosystem, Firma 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.

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 2050Kv Brushless Motor capable of handling everything this ESC can put out that is a perfect to get you driving with Spektrum Smart technology.

WATERPROOF

WATERPROOF

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.

 

EC3™/EC5™ BACKWARDS COMPATIBLE

EC3/EC5 BACKWARDS COMPATIBLE

Firma ESCs feature IC series battery connectors. The IC series of connectors are designed from the ground up to provide a more solid connection, higher heat resistance, and effortless installation. When used with an IC3 or IC5 connector-equipped Spektrum Smart battery, the ESC can receive and transmit battery telemetry data. EC3 and EC5 are also compatible with Firma ESCs for basic operation and ESC telemetry.

 

ONE-WIRE TELEMETRY
ONE-WIRE TELEMETRY

ONE-WIRE TELEMETRY

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

*See compatibility chart for more information.

 

SMART TECHNOLOGY BATTERY DATA

SMART TECHNOLOGY BATTERY DATA

When used with a Spektrum Smart LiPo battery, your Firma ESC provides you with the benefit of battery telemetry that's automatically transmitted to your compatible Spektrum radio in real time.

Spektrum RC Firma 150 Amp Sensorless Brushless Smart ESC & Motor Combo (2050Kv)
In what appears to be typical for Spektrum, I was unable to access the features described in their Quick Hit Tech Tips. There are two tables of options for the ESC on line. One has eight lines, the other 11. I spent a great deal of time messing around with button programming before I finally gave up and called tech support. They informed me that I can't get there from here because of my out of date firmware and software, and advised me to buy a programmer card. I did, and got into another mess with broken links and old updates for the card USB link, and the ESC. Another call to tech support got me to the latest updates. Sadly, it did not resolve the problem of missing programmable feature on the ESC. There are two sets of specs for the 150A Smart ESC, and mine just wasn't as smart. It turns out that three options may have been dropped. Tech support is following up with Spektrum to see if eliminating the features was a design "upgrade." Main thing that's missing is the ability to set the LVC voltage, which was my only reason for buying the programmer. Push button programming works fine as long as you have the correct table. Having the table be part of the paper manual would have been nice, not having a table on line with three options that no longer exist would have been nice too. In a nut shell, printed Spektrum documentation, and documentation on line are a mess. Tech support was good, other than misleading me into buying a programmed that did not solve the problem. The difference in tables of features were news to them too. Other than taking my battery down below 3V one time, the ESC works OK. No problems with the motor, works as it should.
