Hellsavage - I can confirm the diff leakage problem now that I've got some miles on my diffs. I will be ordering the Kyosho P6 o-rings and installing on my next diff maintenance. If you look in the diff photo above, the o-rings that leak are HPI #6811. I'll be replacing both the one on the ring gear and the one on the diff cup.

I guess the other option would be to replace the o-rings with new HPI #6811's every time the diffs are opened for maintenance.

Thanks for the tip, and the link!
