The bathtub frame of the evolved shaft-driven 4WD TT-01 Type-E has its motor and battery close to the ground for lower center of gravity and optimum balance. Mounted on the bathtub frame is a fiberglass reinforced nylon upper deck and gear covers improving rigidity, as well as a 3-piece tie rod providing smooth steering action. The low center of gravity, highly balanced design, 4 wheel double wishbone suspension system, and front and rear differential gears all come together to produce an excellent drive. A host of Hop-Up Option parts are available to soup up the TT-01 Type-E!
