Ok in this hobby anything can bash if you are not afraid to fix it . really though the T4 is a great truck I beat the piss out of one a few years back when they were fairly new and beat the piss out of the T3 before that! I will say though you will break front arms pretty easy, if you replace them with RPM parts you will have no more problems I would also say get a alum. bulk head those were the only up grades that I did to mine that have not already been done on the RTR truck. You will not be disappointed with a T4 IMO they are built to be competitive on a race track and it shows.
