Guys am taking down noetes..
the problem with the rear case is always there what ever shims you put?
i mean if you have the correct mesh again there is that problem?
like the mp9? because the mp9 also has that rear diff case problem...
as for the driving the best i have ever seen i think is the new losi 8t 2.0
but to say the truth i have never seen an st-rr driven by a good driver that spend time with it and had setups...
the 8t i saw was driven by the best driver in that track and it had a lot of practise...but the hadling and speed was very nice...
