Honestly I would call HPI about it. The manual does mention 3s is only to be used for occasional speed runs and things like that but it should at least make it through a pack. I'd at least put in a ticket. They may ask you to send the esc back though but if it is faulty you will receive a new one.
I ended up going with the Castle MMP & 3800KV combo in mine. It really rips and I run 3s pretty much all the time. It's amazingly fun and it is absolutely solid. I can run pretty much for hours on end and not worry about stressing anything due to temps.
For reference on mine I'm running a 17t pinion with the stock 46t spur. It is probably way faster than I need it to be but it still has massive amounts of grunt and it is a blast.
Edit: here is a gallery of pictures of it if you want to check it out. It's mostly mod pictures and stuff like that. http://imgur.com/a/5K0En
