Duratrax Durability

[PRH]

I was running my Big Rock yesterday trying out my Duratrax Six Pack MT belted 2.8's. No Jumps, just running around a baseball diamond at the park. I loved the way it did not roll over at high speeds in turns, so I started pushing it harder to see just how fast I can take the turns. I finally got it to flip. Once I set it upright and excelerated, the back right wheel had a bad wobble. Looks like the plastic behind the wheel nut cracked. The stock wheels took a beating, these wheels cracked after 1 roll over? Take a look at the attached pic. Has anyone else experienced this?

That is a DTX wheel stamped Arrma on it. And apparently Arrma is an OE for many upgrade wheels FWIW.
Just where is the crack? I cant see it in the picture.
