The bathtub frame of the newly 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.Newly designed front uprights (A parts) have been added to improve the handling of the chassis. These new uprights are made from a polycarbonate plastic material, which reduces play, in turn, making steering and handling sharper and more precise.A new upper deck has also been added to increase the overall rigidity of the chassis; this solid foundation yields to better handling and provides a more responsive racing chassis. The upper deck also incorporates a new transponder mount for those that wish to race their car. The redesigned upper deck features a motor guard to prevent new hobbyist from touching a hot motor and possibly burning a finger.The steering system has been completely redesigned to feature the race proven TA05 steering system. This racing inspired steering system helps to provide less play and more precise steering response.New front and rear shock towers are now molded separately from the gear case covers. This improvement makes maintenance much simpler. Now mechanics will have direct access to the front and rear gear boxes without removing the shocks.
