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."

Very fun motor. Made it fit and it’s like a big block in a Miata. Plan on turning this into a F150 Drag truck. Lots of torque and power and good throttle response. I’m coming from a basic brushed motor so I can only say good things. Keeps blowing up gears and driveshafts so it’s perfect

Very nice kit. If your looking to upgrade look no further, this is a very versatile kit and with all the right other things it just comes together perfectly. Definitely worth the money

I have countless Spektrum built rc trucks and they've never let me down. Their 150amp ESC with 2050kv motor works great for up to 6S power. I use them in my bashers because they're durable and rugged. I use them in my speed runners because of the smart tech and AVC which helps you in so many ways. Spektrum has always been rock solid for me and I have no doubts about them making quality products

This is a 1/10 scale redcat racing volcano epx that’s meant to run on a little 2s lipo, but that wasn’t enough power so I got this and lets just say the amount of power going to these non belted 120mm tires was ludicrous. I’m working on making it 4wd again so I can maybe have some control over the car. The motor was so powerful is broke the plastic spur gear and now I’m waiting for it to come in the mail, and just to clarify the break wasn’t bad in my eyes it wasn’t even good it was amazing.

The ESC was dead on arrival. Someone must have returned a dead unit. Hard pill to swallow
