Hi, guys.
I'm experiencing a serious throttling malfunction with my Thunder Tiger Jackal desert buggy.
I've videoed the problem so you can see how it responds to my trigger presses.

It starts exhibiting the issue about half a minute into the video. (The purpose of including the first 30 seconds of it working fine is to show the seemingly random nature of the problem).
Notice how it stops on its own during reversal, hesitates or outright fails to start, etc.

I should note that the battery charge is well above the cut-off point and the radio AA's aren't out of juice.
Also, it is my understanding that the stock ESC included with the unit isn't exactly state of the art, but could there be more at play here?

Thanks for any help or thoughts.
