Buy a slash 4x4 if thats what you want to do....the only upgrades mine has is a king heads motor mount and rpm arms....
This truck takes and amazing amount of abuse...the only thing i've ever actually broke from bashing is one stock rear carrier and that was from driving it 30 feet up a tree and having it fall and land on one back wheel
I would be willing to put money down that my slash 4x4 would out bash your flux
Maby for you it is but if you've seen what i've put this truck through i bet you would have a different opinion...
from reading your threads around the forum i doubt you would have the balls to put your flux through what i've put my slash 4x4 through....and i'm not talking about water and snow, i'm talking about an all out beating
