I had bad luck with both of mine, which is a shame since it was nice when it worked.

Got the 2100 combo a year ago, put it in my E-XXL, and got 10-15 minutes of driving out of it before it would just stutter when starting from a stand still.

Six weeks later It came back(new ESC same motor), and it now worked for about 5 months of little use(winter season). Finally during the first race of the season back in February the new one stopped working. The internal BEC would shut down after 4 minutes, and as I tried to localize the problem, the the period of time between failures kept going down. In the end it would power up, and all LED's would go on when applying throttle/brake, but no movement from motor.


Eight weeks after that I was given a full refund, and now have a 80A xerun ESC.
