Hi Jim fantastic information regards rhys watsonia Victoria Australia

Worth knowing that the rear tire diameter also effects the final drive ratio.

Other variable is car mass, if you lighter some weight from your slotcar. This allows to use higher gear ratio without harm car's previous accelerate behavior. Cheers!

Finally i understand the rgears ratio, Where can i get the Gear ratio spreadsheet? Thxs
