Full official photos and details of Tamiya 42384 TRF421 Chassis Kit

This R/C model assembly kit creates the 2 belt-driven 4WD TRF421, the latest model in the line of TRF chassis; its newly designed carbon fiber upper and lower decks move the motor 22.7mm further forward than on the TRF420X, while the center shaft is in the chassis center and drive belts are of equal size; pulleys are also a new design. The upshot of this is greater pitching stability on the throttle. Bulkheads have a new design for a lower center of gravity, and new USBB (ultra-short big bore) dampers are mounted via aluminum stays: they can be fine-tuned with spacers. The suspension uses upper and lower A-arms for superior rigidity, with identical lower arms front and rear that have a longer span for more linear roll that translates into more control.
