I guess the weight of the motor was enough to bend the front as the truck landed from the flip. Looks like something like a large zip tie could be used to keep the motor firmly pressed to the rear support. That would mot likely cure this issue... Not really a materials failure, just a design consideration. While the rear support prevents the motor from going down (like on a hard regular landing) it does not stop the motor from going up (like a hard upside down landing).
