Damn, it has been over a year...
Let's just say the X-T looks nothing like that anymore besides the front and rear ends. I went back to the stock chassis and made a new motor/diff mount setup that puts the motor in the front-left corner.
I had been driving this buggy with Maxamps 4s 6300mah (2100HV cells), but one parallel group puffed up. So I sent the pack back to Maxamps, and Austin verified a complete pack replacement. However, when I got it back, only the puffed up group had been replaced (I even included a detailed letter and references). So, I hacked up that battery pack for the loose cells, since I didn't want to deal with it any more.
The buggy has just been sitting on a shelf for the past few months, waiting for a battery. I think I'll let it share the 5s2p A123 pack from the Revo) for some insane power. I have some pics from a while ago that show it in its current form:
The battery mounts shown were for the 4s 6300mah pack, but I'll remove those when I work on the buggy again.
