Product Overview

The Spektrum Firma Sensored Smart ESC System is specifically sourced to be used with 10th scale Drag and Speed Run models running 2S LiPo power. Featuring advanced Smart connectivity that reports valuable telemetry data without any extra accessories.

This system is a complete ESC and motor package that includes a Sensorless 6500kv brushless motor and the Firma 100 Amp Smart ESC, providing a Smart solution for your 1/10 Drag car kits and upgrades.

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!



INCLUDES HIGH RPM FIRMA SENSORLESS 6500KV BRUSHLESS MOTOR

The Firma 6500Kv brushless motor features a large 4-pole 8-magnet rotor design, CNC machined aluminum housing, insulated high purity copper windings, high-quality alloy steel 3.175mm (1/8") output shaft, and precision bearings for high durability and smooth rotation. Preinstalled 4mm gold plated bullet connectors.

 

PRETUNED FOR DRAG RACING SETUPS

Drop in and get started quickly and easily on most Drag kit and RTR models such as the Losi ™ 22S No Prep Drag Car Roller. And with the advantage of Spektrum Smart Technology, drivers can use the real-time telemetry data to better tune their setup for faster runs.

 

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.

 

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

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. 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!

 

MULTIPLE PROGRAMMING OPTIONS

Multiple programming options are available. Using the Smart Firma™ ESC Programming Box, you can easily change settings on the trail to suit driving conditions. An easy-to-use Smart Link USB Updating and PC Programmer app is also available. And for those with a Text Gen capable, programming and adjustment of ESC settings can be performed, right from your Spektrum transmitter, no additional modules or wires needed!

 

PROGRAM FROM YOUR SPEKTRUM TRANSMITTER

With the latest models of Spektrum computer transmitters, drivers can take advantage of the Firma Prog text gen menu. This allows you to adjust any ESC setting or parameter right from your transmitter, on the trail, no programming box or Bluetooth interface required!

Questions & Answers
Real questions from real customers. Why not ask your own?
Will this work with the HPI RS4 Creators as I have 3s Spectrum batteries IC5 and would like to use them in this model also. I will be using the #6932 - PINION GEAR 32 TOOTH (48 PITCH) from HPI but if there are better options, please let me know.
Scott / 17th February 2025

That would be a fast system - but only 2s capable. You would need a lower kv system to run 3s.
