Squee: No, just the HB diff.

Example:

A stock Emaxx: diff = ~2.85:1, tranny (2nd gear) = 1.72:1, spur/pinion (66/18) = 3.67:1. That's a total ratio of ~18:1.

If you use the HP Pro diff (4.3:1), you only need a pinion of 16T to achieve about the same final ratio of 18:1. Or, if using a 51T spur, use a 12T pinion.
