Over time all CC-01 suffer from this: the steering rod that goes through the chassis wears out, adding a lot of play to the steering. This makes the handling of the car very unpredictable, even at modest silver-can speeds.
To fix this one can either do a DIY repair job as described in https://www.tamiyausa.com/articles/feature.php?article-id=499. or use a simple to install repair kit from GPM Racing Products. For us the GPM kit was the better route as we would otherwise have to buy parts for the DIY solution.
