I wrote an earlier article about building the IROC hot rods. That article took into account how to build identical cars based on measurements... you know, is the chassis flat, does the top plate match the chassis, are the armature Ohm readings close, are the magnets matched and close in strength etc. If you would like to catch up and read about that you can do that here. Well as good as that sounds that's just the basics... there is more and that is the fine art of tuning the IROC chassis. If you're interested then click the read more link below.

Shoe Bending and Travel Adjustment
I don't know about you but when I got back into this hobby the technology for these little cars had skyrocketed exponentially. One part of this included pick-up shoes especially with bending and limiting shoe travel. I started looking at one particular tool to bend the shoe from Scale Engineering. At first didn't know quite how it was supposed to work, but with time and help I was able to figure it out. Also when I came back to this hobby I didn't realize the importance of shoe travel. That said, If you're interested in this then click the read more link.
