My dual BL set-up

[RC-Monster Mike]

The RD Logics cvds don't work with the 1/8 diffs. The Maximizer diff cups with stock spiders and aluminum cases are very stout gears, though (although I can't seem top get the diff cases anywhere). The stockers won't hold up for two long if you drive hard. The spool will shear the 4 small screws that hold it to the ring gear and stock stock plastic diff will flex and fail.
