Holy mother of pearl... So my HobbyWing ESC is acting up. Not sure if it's the ESC, sensor wire, motor or the battery. When I first apply just a touch of throttle, the motor starts to stutter. I guess this is what "cogging" is, eh?
According to the ESC manual, it's set by default for a pretty high level of "punch" or initial acceleration and thus has "strict battery requirements." Unfortunately these strict battery requirements are not spelled out! (Nothing on the web site, either.) An insufficient battery will cause "stuttering and hesitation" which is exactly what I'm experiencing.
It's a 60A (320A burst) ESC and I'm wondering if maybe my battery isn't up to the job. It's a 2S 4000mAh 20C battery. So that's 80A right there. (80 in theory, I know these sorts of specs are fudged.) I'm going to experiment with turning down the punch setting and see if that improves things. If that alleviates the stuttering then I'll be getting a new battery (I was going to get a shorty pack for racing anyway). I just got this ESC and I'm hoping I won't have to warranty it already!
