The new emaxx and erevo use the same diffs, internal tranny ratios and tire heights. The novak gearing chart is related to the old emaxx though...
I'm pretty sure the chart I posted up thread is for the new E-Maxx, although the new Traxxas part number should have been included in the copy. The new E-Maxx is the reason that we redid the HV shaft/rotor and tooled up the 5mm/32 pitch gears.
