Hello in UK.
I have the same problem with the chassis on the X2C, after a short run.
Bought a new chassis and now will i make a gain in st-servo, which goes out and gets fixed to the front chassis plate, this will be tested tomorrow.
2010 I drove with the X-Pro 2wd both indoor and outdoor racing series in Denmark and have never encountered this problem before now.

sorry for my english
Update: The gain in the front is good, has not broken chassis.
The car is running really good
