I Think I Broke My System!!!

[BrianG]

Well, that's good news at least! So, maybe your problem is in your batteries; a partially broken/loose solder connection on the batteries maybe. Would make sense since a bad/loose solder joint can't supply the current the ESC will try to pull.

Man, I really hope I don't blow my controller somehow when it comes in! I think I'll definitely make some type of ESC box to protect it and support the wires (while maintaining adequate cooling of course). Might be worth the effort!
