Perhaps I'm getting a bit carried away with this... When I started, I had the intention of just moving the rear axel back so a Hot Wheels car would be able to fit on it. Now its getting to the point where I'm actually building a new frame for the guts so it sits lower as a whole and (if I can find some small enough cogs) mount the motor centraly to avoid thoes annoying pulls to the right.
Back to my original question, how many mods do you have to make to a bit before it's no longer a bit but rather a custom micro R/C?
Rhetorical question, really.

I need to boost my post count somehow and adding an 'I agree' to other people's posts is a lame way of doing that.
