Even during hard crashes clip doesn't act as support for body, so no stress goin' to tank in such configuration.
Body is stock, and i have no idea how it looks with FTW body.
Vandalzzz,
I know you said it was the new revised tank but from the pictures that looks like the old tank, this could be your main problem if you are cracking the tank.
