I would look at a few things, such as the suspension movement. If the too much travel is allowed in the suspension , the cvd will bind in the cup and cause this to happen. That is rather disappointing to hear, though. I bind in the suspension or a severe flex in a suspension arm (which would also cause a bind) would be the culprit I suspect.
don't feel bad, in my t-maxx, i shredded the end (the CVD end) of an RDlogics which everybody gives outstanding ratings too. I upgraded to UE (which cost an arm and a leg i might add)
If the vendor is an actual hobby shop, they may be able to go through their distributor to claim or at least try to claim a manufacturers defect. It is worth a try. Either way, it won't happen overnight. Try to contact MIP directly.
