Pro Racing Motor and Chassis Timeline

By Steve Okeefe

(with a little help from his friends)


Pro Racing Timeline 170102.jpg



This update, the first in several years, generally adds greater detail and clarity in the 1970 to 1973 time frame.


Changes include an attempt to more accurately depict when the C-can motor first arrived on the scene.


Additions include new tags indicating general trends in chassis design (lighter vs. heavier and shorter vs. longer), design improvements to further isolate front wheel function, the advent of NCC car and motor classification, and increasing design dependence on aerodynamic down-force.

Very interesting for those of us who never raced Slot cars in this era.  Is there a similar chart from '73 onwards?

Champion of Chamblee did have .005 laminations around the "Orange Picker" timeframe. the legs were pretty wide like 3mm or so. I do not recall seeing .010 thick laminations out here in the wild west, If I recall correctly even Reeteez was using Champion .005 arms with very thin blue hysol coating.


I note that Blue Dots and then White Dots were not listed in the chart, DZ's were good but the molding on Blue Dots was better.
