For my purposes - mild modified in a shortcourse 2wd truck, 2S Lipo, properly geared.... do I really need a Mamba? I was ready to get the Sidewinder SCT combo, but then I see many complaints on the ESC and how people upgrade to the Mamba.

From a technical angle, isn't the Mamba just a "heavier duty" Sidewinder, capable of 3s (and maybe 4s in the latest model)? I'll never use that capability, so the extra $ seems like kind of a waste for me.

Am I missing something here?
