Just tried switching the tracks. Helps a little but still lists.

So looks like its either the wheels or the motors. (I suspect its the motors). Any more ideas?
Well, for me, it's the radio. I know this because my old radio that came with my Bulldog worked fine with the trim centered. My new radio that came with my Panzer, as I mentioned before, has to be trimmed all the way to the right for it to move straight, and that's with both tanks, Bulldog included. So maybe that's your problem too, the radio.
Do you have another HL radio you can switch out crystals and test it?
