A cracked body shell on your YIKONG YK8081 RC Car after a hard landing, even with the Body Inside Support (80054) installed, can happen if the impact exceeds the strength of the plastic shell or support. This is a common fault with high-speed off-road trucks due to their weight and speed. Inspect both the shell and the support – if the support is cracked, replace it, and consider reinforcing the shell in vulnerable areas.
