Yeh I've noticed what the power pack does, it makes a big difference (I wouldn't of though it would), weighs down the back end making the springs stiffer. I'll move it, see what results I get.
I will consider getting the UE extension too, instead of Gorilla, so I can use my Titanium skids, I love my Ti' skids. :D
The ESC is mounted on a metal bracket (the type you get for putting shelves on the wall) and I just bolted it through where the 2nd motor went. Very sturdy but maybe abit too high.

Thanks, glad you like my truck, took me ages getting here! :)
