Butler,
NO mod's for the Bit-Char-G. Believe it or not
I am too focused on my Micro RS4 right now.
I've also debbled in some Square wheels and Kyosho slicks for my Mini-Z F1's.
The Bit Char-G is just plain sweet and simple and it's exactly how I want it to stay.
Oh, my wife played with the Bit Char-G earlier this evening

I asked her if she'd like one, she declined the offer

Unofrtunately she was bored with it before I could get my Mini-Z prepared to 'bully' the Bit Char-G.
Butler, once that track of yours is completed, I am coming over to whip your ass with my big bad CLK.
