just installed BL-WOW-now problem

Was that first video full throttle? Sounds almost like a little clicking of something catching, then not catching. Could also be an unfortunate MMM failure though. Do you have another ESC/motor setup to test and make sure it's not either component (do all possible combinations if you can).

I don't have my MMM yet but that does not sound like an esc failure, it sounds like something is grinding. Maybe the diffs? Have you disconected your motor and try rolling the truck yet?

Yeah, I'm starting to think it's not an ESC failure. I figured since he said it ran fine in the air, but when on the ground it did that, that tends to be a sign of a blown or screwed up phase from my experience.

It does sound like something is up with a diff though; more probable I would guess.
