Spektrum Firma 85 Amp Sensorless Brushless Smart ESC & Motor Combo. 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.

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!

Spektrum RC Firma 85 Amp Sensorless Brushless Smart ESC & Motor Combo (3300Kv)
Installed into an Armma Granite 4x4 MEGA 550. This kit is a direct drop-in that doesn't need to be programmed as long as you are using a Spektrum receiver. I am using the stock Pinion gear to ensure no overheating. This upgrade adds much-needed top-end an granite. The ESC has the same mounts as the original esc so you can screw it right down no tape needed. I am running with 2s 30c lipos and it does great. I would not recommend going anymore than a 14 or 17t pinion on this setup.

Overall for $100, this is a very inexpensive upgrade that added much-needed life to my brushed truck.

Spektrum RC Firma 85 Amp Sensorless Brushless Smart ESC & Motor Combo (3300Kv)
I got this kit to install into my Arrma Infraction Mega. Fit perfectly and the ESC is a direct mount high on the receiver box or low on the chassis. I’m using a Spektrum 3s 5000mAh 100c battery with zero issues. Gearing I used the stock 57/15 which keeps the motor and esc temps in a happy place with very little cogging. I can tell you that the motor and esc doesn’t like gearing 50/20! Not only does the temps go up, it also cogs really really really really really bad! So I went back after 5 minutes of driving and put the stock gearing back in.
No issues so far, I have over eight battery packs through it. No cutting out issues that I’ve read on other forums, the temps are perfect while driving hard on the throttle. I recommend this for anyone who wants to upgrade to a brushless set up. It’s really good, easy to use and to program (get the programmer card) unless you only have MAC, only works on windows.

Pretty good, I sort of expected the motor to be a bit faster but the Smart ESC has been fantastic.

It Looks Great Inside the Box.
As soon I can get some time off going to put it in a Reflex DB10 chassis.
I hope it runs as good as it looks
