I’ve heard complaints about similar Zongshens having fragile plastic, but whatever they use at CSC is really good (and cheap to replace once I’ve beaten it up enough).
If anyone does manage to crack plastic, though, I definitely recommend the super glue and baby powder option. In my case I repaired the right fairing, which had snapped off cleanly from its mount point, and it still survived this more recent impact as well as I did.
