This is our home made copper taped HO MDF track raced non-magnetic!. I made some modifications on my Tomy AFX mega G car to run it on this track: Mod1) Add some lead on the front and rear of the chassis. Mod2) Replace the pickup shoes with copper wire (I used NSR 4824 Ultraflex silicone motor wire) mounted to the brushholder with the tip of a toothpick. And lower the voltage to 6 Volts. I used a Parma 45 Ohm controller.
