Slot Car Drag Racing Gear Chart

 
Everybody has a gear chart, right? Well, not everyone, as it turns out, and sometimes not for a wide enough variety of ratios. Besides, it's easier to do this than to mail one to you-know-who. If the gear ratio range you use isn't on here, you're still using those Cox repro 48-pitch FRP/nylon inline gears, aren't you? Where the molds are way more than 30 years old? Yum. Best of luck to you. This page looks different than most of the others here because it's designed to be easily printed out, even in low-resolution mode. Well, at least it works that way on my printer. If you have a problem, let me know.
