Hey Jeff, I also used 30k in the rear diff initially and found that the rear was on the edge of grip. I have now changed to 10k and it seems to hook up much more solidly. Just a thought.
I also found in both my fw and the new RRRthat the kyosho shock diaphrams leaked after very little time. I have changed to the trf tamiya flat diaphrams and they hold the oil much much better.
Thanks rcosmax. I will try a lighter rear diff, although I had to go up to 15k on my FW for the same track to gain on power steering.
