The Tmaxx is weak! I had one that I modded very highly and it still was not up to par in reliability. A arms, turnbuckles, bulkheads, shocks and towers are weak. You need to upgrade all the arms with RPm arms, Bulkheads with aluminum and shock towers with rpm. All teh axles and drive shafts are weak expecially the rear shaft. They will eventually twist and break. I would take an avalanche over a tmaxx any day. If you really had teh money to spend and you want the best it would be the savage, MGt or even a revo if you had to go to traxxas. Those are your toughest trucks and the t maxx is at the bottom for reliability in stock form.
