I haven't seen one for brushed motors. I would put a lot faith in that chart though. It'll be a good base line but there are a bunch of variables. Internal gearing will change the final drive ratio. I haven't looked at the chart but I imagine they took that into account. But is that chart based on touring car sized tires or truggy sized tires or somewhere in between?

Or you could use this... http://www.scriptasylum.com/rc_speed/_solver.html There are a whole bunch of useful(and useless -- for crawling) calculators on this site.  |

Yes, the link I posted did not factor in any ring/pinion gearing or tire size. I know it is not an absolute, but it would be interesting to see. |
