DAVEW: Yes, you saw it here, I was actually able to make something with my dremel without scraping a huge line across it!
I may be getting better at this!
A good tip for making yours, if you do so with a dremel. Buy one of those metallic sharpies that write on dark surfaces and draw your design on the graphite, with the outside of the lines being your desired boundaries. Then cut, with the cutting disc, like half a centimeter around the whole thing. After that, use a dremel sanding drum to grind to the edges of the lines.
Doing it this way, I was actually able to get the lines straight and smooth. The graphite grinds very easily, it just makes a huge mess (especially in your nose if you don't wear a dust mask
You probably don't need any tips from me, though. I remember seeing last year's tc3 with 4 cells on one side, two on the other, and a tunnel in the center for weights. That thing looked fresh from the mold!
BIGDON18: Thanks, I race at Toys for Boys Raceway, which I shorten to TFB to alleviate concerns that I race at an adult bookstore
Check it out at tfbraceway.com. We are racing indoors on carpet right now for the winter. When it gets warm, we will move back to our awesome asphalt track. There is also a good off road program, but I've never messed with any of those cars, well, unless my old traxxas trucks count.
