About this part

Spektrum Firma 130 Amp Sensorless Brushless Smart ESC & Motor Combo, with included 1900Kv motor. Like every component in the Spektrum Smart ecosystem, Firma Smart ESCs combine "plug-and-play" simplicity with the ability to communicate with other Spektrum Smart electronics.

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 Smart compatible transmitter in real time, allowing the ability to adjust settings as needed to boost performance on the go.

This ESC comes bundled with a Spektrum Firma 1900Kv Brushless Motor capable of handling everything this ESC can put out that is a perfect to get you driving with Spektrum Smart technology.

*NOTE: Smart functionality requires use of Spektrum Smart compatible battery, transmitter and receiver.

Wil WhiteVerified owneron Spektrum RC Firma 130 Amp Sensorless Brushless Smart ESC & Motor Combo (1900Kv)

It’s truly an amazing combination between the high power ESC and all the programs you can set up. And the motor is outstanding I’ve put it in an Losi 22 roller with the Extreme racing carbon fiber chassis and new carbon fiber drag bar. Going on a GTO top by Pro-Line. Tires are still stock awaiting more upgrades to come in. Great product would recommend it to everyone. ????

If you are on the fence about getting this setup, just pull the trigger….. The amount of power this combo puts out is insane!!! I’m running this in my Typhon 3s on 4s 5000MAH 100C, 26t pinion and the motor just gets warm and this thing rips! I am going to push this motor to its limits before I put a fan on it.

Runs great on 4s, however the Arrma heat sink shield that fits this motor will not on a Arrma Vendetta.

What reviewers say

Four reviews, all for the 1900Kv variant, rate this sensorless brushless ESC and motor combo positively, averaging 4.75 out of 5. Reviewers consistently describe strong power and good motor performance, with one noting the motor stays only warm under a 26-tooth pinion on 4S LiPo. Owners report using it in buggies and trucks such as a Losi 22 and a Typhon. One reviewer notes that the Arrma heat sink shield designed for this motor does not fit an Arrma Vendetta. Reviewers also mention the ESC's programmability. Sample size is small, so these impressions rest on limited feedback.

  • + Strong power output
  • + Motor runs warm rather than hot
  • + Programmable ESC features
  • + Runs well on 4S
  • − Arrma heat sink shield does not fit Vendetta
