About this part

The Hobbywing QuicRun 10BL120 G2 120A 1/10 Sensorless Brushless ESC is designed to be an extremely efficient ESC to improve stability and reliability. The cooling effect of this ESC comes from the integrated radiator design combined with a copper thermal coating. Capable of pumping out 120 continuous amps, this ESC is ready to hit the dirt!

This ESC is given an IP-67 waterproof rating to guarantee excellent water and dust resistance. The whole power system is able to drive on a variety of surfaces including mud, sand, ice, snow, and water without damaging the power unit. The built in capacitor improves both the efficiency and brownout protection. The ESC also features capacitor thermal protection and aids in protecting the ESC and the ESC's capacitors from bursting due to overloading.

This is a update for this item and I change the ratings for one reason I found, still a great esc but with some limitations. What I found the esc is capable of moving g some specific motor lengths. 3652 is possible, 3660 is possible to, and 4268. Any person will and what is the issue well. Even if the 3674 is inside the amp specification they will have some problems. Even the motor 3668 firma have is because I have outcast v2 they can't move that properly well causing some lags at lunch. Can I recommend this esc yes is a great esc but have some limitations on the programing of what type of lengths motor can use, but still a great choice is you want some capable esc. Even a out runner 4254 this esc can move. The motor need to be inside the length required

I received one that had a weird issue where it couldn't quite hold full power. When I floored it, it would cut out for a just a millisecond, then resume- and it would repeat this constantly under power. 5 stars because Amain replaced it without question, and I have one that works great now. I just wanted to post this in case anyone else was having this issue. I've generally had great luck with hobbywing stuff

Excellent product, I recommend it. Amain is the best for spare parts.

What reviewers say

Reviewers generally rate this ESC highly, with most giving 4 or 5 stars and describing it as working well in a Slash 2WD. One reviewer reported that a unit cut out momentarily under full power and was replaced by the seller without issue. Another reported that some motor sizes performed poorly, including a lag with a 3668 motor paired with an Outcast v2, though that review is hard to read. Programming is a recurring point: one reviewer found that it cannot be set with the Set button and needs the Hobbywing program card, which the reviewer had not expected. Reviewers also note that it works with the Hobbywing LCD program box and praise the seller for spare parts and replacement support.

  • + Works well in a Slash 2WD
  • + Seller replaced a faulty unit without question
  • + Compatible with Hobbywing LCD program box
  • + Good overall ratings
  • − Cannot be programmed with the Set button; needs program card
  • − Reported motor compatibility issues with some motors
  • − One unit cut out momentarily under full power
