XRAY xb808 electric motor mount

i know this is a little off topic, but close, has any one noticed that the diff cases on an xb808 start stretching, it caused a chain reaction, like so- the case stretched and then the bearing has more room to move, which the conical gear and the pinion start stripping...
i very dislike the some of the design of this buggy. the flaws i see are:

-13x19, and 8x14 bearing failure a least 1 every 2 months
-the diff case stretch because they are thin...
-the rear of the buggy love to steer for you

but other than that it is a great car.
