XRAY - Model racing cars

sounds like it's locked up in the rear, 10,000 is alot,

You could also try the plastic rear brace or no rear brace at all. Other things that come to mind are more rear negative camber and toe in. And I agree on softening up the rear diff.

try running 3.5 rear toe in and also 3.0 negative rear camber, and also I agree that the 10,000 rear diff oil is way too much, try something like 2k or 3k and that should help dramatically

For that race I didn`t use a brace because in the main it got very bumpy. Otherwise I`m using a alu brace with "one hole" cut off or the plastic.
