e-revo weakness diff

[BrianG]

Shimming the diffs involves two sections:

- between the bearings and the diff on each of the outdrives. This moves the pinion closer or further away from the ring gear.

- between the pinion and the pinion bearings. This pushes the pinion closer to the diff cup.

If either of these are off far enough, you are not getting a good mesh and could strip the tops of the teeth off. Of course, even if shimmed perfectly, a powerful enough setup will destroy them anyway.

I had my BL Revo (converted 2.5, 9XL, 14 cells) for about a year or so and never had a diff problem.
