Hobbywing Xerun V3.1 Stock Spec Sensored Brushless ESC
I have been running this ESC in my 22 3.0 for a few weeks now. I was running 17.5 with the fan attach and this is a smooth ESC. I just recently dropped a 7.5t motor into my car and this ESC handles it just fine with no issues. I have used all the top ESC (Tekin, Orion, Novak) and the quality of this ESC is just as good but for a more reasonable price. The LCD program box is a good additional as well to help fine tune your ESC.)

Hobbywing Xerun V3.1 Stock Spec Sensored Brushless ESC
A smooth, tunable, and reliable ESC with strong brakes. I purchased the V3.1 Stock Spec to pair with a 17.5T motor, but I've also run it quite a bit with a 8.5 turn. I've even run it with a 6.5 with no heat issues. The tuning parameters of this ESC are a great selling point. You can adjust multiple throttle, punch, and braking parameters in order to maximize performance on a variety of track conditions.)

Hobbywing Xerun V3.1 Stock Spec Sensored Brushless ESC
Smooth esc, ran it in a B5m with. Reedy 17.5 for a while before switching the motor to a tekin 8.5. Esc will take a 10 minute main on a tight track with lots of brake, gas, and back again and come off the track at 125 degrees. It's worth the money for sure, easily programmable with the LCD box and very reliable.)

Hobbywing Xerun V3.1 Stock Spec Sensored Brushless ESC
I bought this ESC and the digital programming box for my new associated SC5M short course truck a while back. I have benn running this now for about 4-5 months and I am super pleased with this purchase. It's easy to use and program. I have used the pre set tunes for most of my practice and race sessions. Great price. I would recommend this to anyone who wants a great cool running ESC that is pre programmed yet still allows you to program your own tunes tunes if you want. I plan to buy another one for my B5M Lite buggy that I'm building right now

You will not be disappointed with this ESC

Hobbywing Xerun V3.1 Stock Spec Sensored Brushless ESC
As with all the Hobbywing stuff I've bought, I am impressed. I started with the V3.1 120A in my SC5M, and was thoroughly impressed. When I finished my B6.1 build, with this ESC and a Fantom 17.5 Works, I was also very impressed. It is smooth, precise, and runs cool. With the WiFi module, it makes checking the health between heats a breeze. Motor temps and ESC temps are all logged, as well as max RPM and volts. So coming off the track, it's easy to see where changes need to be made to gearing. My only complaint is that these things have become so popular, that they are never in stock.)

Hobbywing Xerun V3.1 Stock Spec Sensored Brushless ESC
Purchased this esc with confidence because my friend has 2 of these and perform great.
Was running perfect until I wired up a reedy sonic m3 10.5 motor then the esc became permanently Blinky.
I tried reprogramming and new Censors cables but couldn't fix the problems, maybe I should have read the instructions and noticed that the esc is only compatible with certain motors with inboard temp censor (Beware))

Hobbywing Xerun V3.1 Stock Spec Sensored Brushless ESC
The built in on/off switch is a pain to use and my esc quit the second time I used it. I'm going back to my Tekins.)
