e-revo rear bulkhead?

[E-fanatic]

So I am haveing issues with the rear bulkhead breaking. I did some jumping yesterday and landed every jump on the wheels The only thing is that some how during the mix the rear bulkhead broke AGAIN . I have had it break about 6 times now and only once was from hitting something at 5mph, 2 of them from cartwheeling, and the rest is from just general running in the yard? Since I put the wing/bondy mount brace in, this is now the only part I have left breaking(well besides the diffs but thats a whole other issue)

Is there any bulk upgrade for the revo?
