Also, try the kyosho balls first, unlike the zx5 ones, mine is 3 meetings old and still abso perfect, The zx5 std balls would have lasted about 5 mins lol. Its prob the fact that its not under as much strain and for some reason, the diff gets away with being able to run quite loose.... Unsure as to why but its fine.
I'll prob upgrade come rebuild time, but as of yet that seems quite a distance away.
