Sidewinder SC esc issue

[bdebde]

A guy at the races last week had a similar issue... if you give it large amount of throttle, it would cog or make strange noise. If you accelerate slowly, it would ramp up fine. The shop where he bought the system had seen the problem before and it was an ESC problem. I had a spare in my box and got him going for the races. Never hurts to send in the whole system, often castle will tell you the same.
