Weird ESC or Motor issue (MMM/Neu)

[jpoprock]

Hey all! It's been a while!

I finally ordered a new 6S Turnigy Nano-Tech 5000mah 45-90C Lipo for my E-XXL. Got the battery all charged up and balanced, updated the FW on my MMM to the newest Beta, fired up the truck... but it won't go forward or in reverse at all, or at super low speeds. If I pick the truck up off the ground, it explodes into a hot rocket in my hands. Take the pinion off, and the motor responds to my trigger as it should. It's only when the truck is on the ground. It's like there is an invisible force field around it that causes it not to want to go? The tranny isn't binding up, and the driveshafts aren't loose. So I have no clue what to do.

I tried to reprogram the FWD/REV points on the ESC to my DSX3 Sport, but I don't have an on/off switch. So, I had my son pull the trigger on the radio while I plugged the battery in (Pinion off). It beeped as it should, then flashed red indicating that I was to move to the REV position... but it never beeped telling me to go to neutral? So, maybe I messed it up, or maybe it didn't work at all?

The truck was working fine a YEAR ago when I ran it. But this spring my Lipo shorted out inside and puff daddied. I never got around to getting a new one until recently. Been driving other trucks, if at all.

Usually I can figure this stuff out... but I've not seen this type of problem before. Any ideas?
