Global TopTRF421 Chassis
The TRF421 is a 2 belt-driven 4WD chassis, the latest in the TRF (Tamiya Racing Factory) series, which offers a plethora of setup options and easier pit work. Its motor has been moved into an almost central position and drive belts are of equal size, contributing to greater pitching stability on the throttle. A choice of one- and two-piece versions of the upper deck lets you fine-tune your setup, and the suspension uses upper and lower A arms, with the latter employing ball connector mounts. USBB (ultra-short big bore) dampers are mounted via aluminum stays, and can be further fine-tuned with spacers. The drivetrain also features numerous updated parts.
