Hey everyone! I'm new here, just read through this entire thread, what a journey lol. Anyway, I just got my XS a couple of weeks ago and wanted to chime in and say that I've run around 5 or 6 packs of 3s and the same amount of 2s through it and the ESC has been fine so far. It did randomly get "de-programmed" once, and we had to use the Castle Link to get it set up again, that was weird.
As far as bashing goes, like most people here have mentioned, it's a blast to bash, but I have noticed that I tend to break things 90% more often with the 3s than with the 2s. The 3s speed is addictive though
Anyway, I look forward to following this thread and upgrading the XS when the time comes. As of right now, I've replaced the stock servo with the Traxxas 2075 and the improvement was very noticeable and welcome.
