X6 Chassis problems.

[gordy]

I bought my X6 a couple of weeks ago, along with Rich Davis, we've both nticed today that both the cars have cracked chassis's. They've cracked where the rear most front kick up plate screws thread differectly into the chassis, infront of the servo post, parallel to where the bolts go through. Both cars have identical damage.
Just wondered if anyone else has suffered this problem, or whether we've got a couple of freak chassis's. I can understand them cracking if we hadn't tapped the holes - but we have.
cheers
