Exceed Sunfire Question

[cbaumler]

I recently purchased an exceed sunfire pro buggy, brushless version.  This is my first entry into the hobby and so far I'm having tons of fun with the car. 

I have read most of the negative posts regarding the exceed, so you can spare me that.  I understand this is an entry level car, and that is what i wanted.

Anyway, here's my question, the car works fine except for one issue. 

The car sputters and jerks at low speeds.  It's an annoyance more than anything else as once i give it more power, it runs great.  This should be fixable. 

Any idea where to start?  Is my ESC bad?  This happens on a fully charged battery btw.

Thanks in advance.

Try adjusting the throttle trim.
