The TA series of mid-range on-road car machines has been running since 1991. This 7th generation 4WD R/C touring car chassis assembly kit is endowed with a design influenced by data from the TRF (Tamiya Racing Factory) team s top level racing activities. It is based around a composite structure that consists of a narrow lower deck and an upper frame, and gives optimal torsional rigidity which can be further adjusted by removing the frame center section. The highly efficient single belt drivetrain offers 3 motor positions, each with its own performance characteristics suited to different tracks and setups. Proven TRF419 suspension, gear differential units and steering components are joined by TRF dampers and universal shafts to make this chassis a hi-spec racer!
Further Details from Tamiya s Design Team:
The upper frame allows for a symmetrical chassis design, which in turn helps to optimize chassis flex. Note: that front/rear stiffener, and center brace parts are attached separately to the integrated lower and side frame piece.
The efficient single belt winds back around the main and counter pulleys. Using one belt as opposed to two facilitates the changeable motor position feature. It allows simple reconstruction of the chassis using the existing belt rather than many different lengths.
The 3 motor positions cover a total range of 52mm. Changing motor positions is easy; just take off the cover, remove 2 screws, and re-attach the motor mount in the desired position.
TRF419 suspension parts and gear differentials give top-level performance and reliability. Like on the TRF419, the servo mount is attached on one side only, with chassis flex in mind. The battery can be removed via the chassis side.
