[_paralyzed_]

I went digging around the traxxas forums before I responded to make sure I was giving correct advice. Arct1k is absolutely correct, you do still run the risk of blowing the internal bec, which kills the esc. But the guys over at traxxas have ran these esc's with a single lipo, and running an external bec is how they did it.

To run the bec you just wire it to your esc plug, black to black and red to red, then when you plug in the battery it will be powered. If the voltage of the bec output is selectable, choose 6v. Then you simply plug the other end of the bec into any open port on your receiver. Now the bec will power the receiver and servos.

On a side note, the search engine on the traxxas forum SUCKS. I ended up googling to find the info.
