Tamiya finally announced information on the new TB-04 Pro chassis. This is the evolution of the TB-03 chassis with some unique features. The most noticeable is the motor position, once parallel to the main driveshaft. It has now been repositioned to be perpendicular, similar to belt driven touring chassis. This change will effectively reduce torque steer faced by many shaft driven chassis. Another change is the shorter dampers. They appear to have larger damper oil capacity but shorter overall length. Still able to utilize traditional length Tamiya springs, this chassis may be more fit for touring and RC Drift. The Caster Hub (C-hub) has been changed 6 degree caster and redesigned for functionality. The change is caster will yield better overall control and steering response. The new Tamiya TB-04 Pro is scheduled to be released in September of 2013. Body, battery, motor, RC mechanical, tire, wheel, etc. are not included with the kit.
