Good call on the Batts Jazz.
Tonight I got home and pulled apart the drivetrain and put liberal amounts of graphite powder on everything and used metal bearings in place of the plastic (at least for the 2 pieces on the drivetrain)...MUCH smoother.
So I took it out, using some fresh from the charger batteries and she runs like a CHAMP!
...Then I swapped in the alkalines I used last night (they average 1.35v each, which come to think of it isn't so good considering they're alkalines) and indeed the truck barely moved using these batts.
