Description
Overview
The Tamiya Dark Impact is a high-performance 1/10 scale 4WD off-road buggy that was born and bred on the racing circuit. Even while still in prototype form, this buggy was already hitting the track at competitions as part of Tamiya's rigorous research and development process. The result is a race-focused machine built on the refined DF-03 shaft-driven 4WD chassis, featuring optimized vehicle balance, efficient power transmission, and aggressive styling that commands attention at any track or trail.
The DF-03 chassis represents Tamiya's refined approach to shaft-driven 4WD buggies, with a durable monocoque bathtub frame that positions heavy components low and central for optimal balance. The mid-rear mounted motor and longitudinally placed battery create excellent weight distribution for confident jumping and aggressive cornering. With ball differentials, extra-long suspension arms, CVA oil dampers, full ball bearings, and high-density spike tires, the Dark Impact delivers serious off-road performance right out of the box—with extensive upgrade potential for competitive racing.
