It's not a dumb questions but you'll get a bunch of dumb answers , well not really dumb more like biased.

Here's the deal about ESCs, almost all will do the job. Some will do it better and those would be the LRP, Viper, Tekin, Hobbywing, Speed Passion, Black Diamond and the list goes on. Pick one that others use at your local track so you can share set ups and troubleshoot if necessary. We had one guy at our track last Sunday asking how to program his Havok and all he got were blank looks, someone downloaded the manual and finally was able to help him out. That's another point, always bring your manual with you.

I tried out a Duo3 and it was pretty good.
