Tamiya TB-04 Pro Version II

This is a limited edition release of the R/C TB-04 PRO chassis kit. The advanced on-road chassis is paired with upgraded parts, including some from the Tamiya Racing Factory TRF418 chassis, for a thrilling blend of high speed and crisp handling! The chassis features a number of newly-designed parts and provides a blend of speed and handling that R/C racers are sure to enjoy. The Tamiya TB-04 shares the same double wishbone, independent suspension parts seen on the TB-03, TA-05 Version II and TRF 416/417/418 series of proven chassis designs. It is expected to be available in the by the end of this month for around $450 USD.
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.
