Fast gear mods

[mbartell]

I got one of the tyco fast gear cars, and figure that the only big diffrence between it and the audley cars is that it uses a motor for steering instead fo a magnet.
I put in a four cell battery pack from radio shack- it took some dremeling, but it fits under the mini cooper body. It's the four cell that arranges the batterys in a square. I just dremeled off the top of the battery case and pushed it thru. The "frame" is still prety rigid, but I don't want to run it with the body off.

Then, I found out about the relay mod. So the big question is, does anyone have a good circut diagram to show how to hook up the relay mod? I can't use the pre-made kit, because they use 3v relays, and I want to use 6v ones, rated for a high amperage, if I can find them. The 6 pin relays are pretty common, and should have a standard way of hooking up.

I can almost see how they are put together on the canracers site, but I would be more comfortable with a circit diagram to make sure I have the diodes pointing the correct way.

any sugestions or a link?
