I run a very similar setup with that same esc/motor combo you mentioned and it worked ok for the most part but I'd periodically get random glitches while driving.

Sometimes on tighter portions of the track I race at I'd lose steering briefly, or on a high-speed sweeper where I was at almost full-throttle while holding a long turn. A couple times the glitches almost caused a very serious crash!

I since added a capacitor to the system and I've yet to experience any of the glitching. I'd highly recommend that for sure. Cheap insurance!
